20180150774
The present application claims priority upon Japanese Patent Application No. 2016-230279 filed on Nov. 28, 2016, which is hereby incorporated herein by reference.
The present invention relates to a transportation service information providing apparatus, and a transportation service information providing method.
In the field of providing transportation service, such as railway, bus, or taxi, transportation service is planned preliminarily or each time in accordance with demand (hereinafter, referred to as travel demand) of users who use such transportation services. Note that the aforementioned transportation service plan also involves plans to be prepared after having received a request from a user, such as dispatching a taxi, in addition to preliminarily prepared plans such as railway or bus operation plans.
Although transportation service is planned after having preliminarily predicted travel demand to some extent in order to perform efficient vehicle operation or prevent shortage of transportation capacity, timely actions are required in response to momentary situation taking future travel demands into account, in order to handle minor daily variation of demands or unexpected events such as operation failure.
As a related technique for taking such a measure, Japanese Patent Application Laid-Open Publication No. 2016-085734 (Patent Literature 1) has disclosed therein a means for calculating a set of vehicle services to be provided for boarding requests, on the basis of prediction of future demand for respective services and probability of respective services being selected by passengers. Accordingly, Patent Literature 1 suggests that it is possible to present information (options) relating to transportation services which may improve the sum of the profit of transportation service provider and the degree of user satisfaction, taking into account future travel demand.
Patent Literature 1, however, is intended for a transportation service that covers the entire route from the input departure point to the arrival point by one and the same vehicle, and does not assume a transportation service that covers a part of the route from the departure point to the arrival point by another vehicle. Accordingly, when an unexpected event occurs in transportation over a medium or long distance, there is provided only information of a transportation service that covers the entire route of the transportation with one and the same vehicle (e.g., special transportation service). Practically, a special transportation service often turns out to be a small- or medium-scale transportation means such as taxi, shared taxi, or bus, and therefore the cost required for transportation over a medium or long distance turns out to be high with the technology disclosed in Patent Literature 1.
The present invention, which has been made in view of the aforementioned circumstances, is intended to provide a transportation service information providing apparatus and a transportation service information providing method for providing useful transportation service information.
An aspect of the present invention for solving the aforementioned problem is a transportation service information providing system having a processor and a memory for providing information on transportation from a departure point to a destination point by a transportation facility, the system including: a transportation facility specification unit configured to specify a transportation facility that performs transportation from the departure point to the destination point; a special transportation facility extraction unit configured to extract a special transportation facility which is a different transportation facility from the specified transportation facility and performs transportation for a partial section in the transportation from the departure point to the destination point; a special transportation facility specification unit configured to specify the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point, in a case where the extracted special transportation facility satisfies predetermined conditions relating to the transportation for the partial section; and a special transportation facility information output unit configured to output information on the specified special transportation facility.
According to the present invention, it is possible to provide useful transportation service information.
Problems, configurations, and effects other than those mentioned above will be apparent via description of the following embodiments.
Hereinafter, embodiments for carrying out the present invention will be described, referring to drawings.
A transportation service information providing system according to the present embodiment is applied in a transportation network including at least one or more types of transportation facilities (e.g., traffic vehicles, such as train, subway, airplane, and ship).
Although each of such transportation facilities (hereinafter, referred to as normal transportation facility) usually transports its users from a predetermined departure point to a destination point, an alternative or additional transportation facility (hereinafter, referred to as a special transportation facility, including, for example, special train, shared taxi, specially operated bus, or the like) will be operated in case of a change in the users' usage form or other factors (when, for example, a large-scale event is being held, or an unexpected event such as a disaster or an accident has occurred, which is referred to below as service failure time).

The traffic-jam prediction unit 141 has stored therein information on backup of an irregular service (e.g., a traffic-jam section length of a road, or travel speed in a traffic-jam section of a road), out of traffic-jam information. Note that the traffic-jam prediction unit 141 has stored therein not only the past or present traffic jam, but also information on traffic jam over a predetermined future time zone predicted from the past or present traffic jam.
The communication unit 142 communicates with other information processing devices. For example, traffic-jam information calculated by the traffic-jam prediction unit 141 is transmitted to the special transportation service planning device 150 via the communication unit 142.
The input unit 151 accepts input of information from a user. The input unit 151 includes a transportation condition input unit 1511 and a special transportation facility selection unit 1512.
The transportation condition input unit 1511 accepts input of conditions relating to the departure point, the destination point, and a time zone of the transportation, and optionally, accepts input of conditions relating to at least any of a via-point between the departure point and the destination point, cost relating to transportation from the departure point to the destination point, time required for transportation from the departure point to the destination point, and time required for transfer at the via-point.
The special transportation facility selection unit 1512 accepts selection of a special transportation facility extracted by a special transportation facility extraction unit 1591 described below.
The storage unit 155 acquires transportation service plan information from the transportation planning device 110 and stores the acquired transportation service plan information in a transportation service plan information DB 1 (DB: database, the same goes below).
Here, the transportation service plan information DB 1 will be described.
Among these, the departure-and-arrival item 106 has respective items of: a point 103 for storing information specifying a departure point of the transportation facility specified in the name 101, via-points (passing points, or stopover points) of the transportation facility specified in the name 101, or the destination point (final arrival point) of the transportation facility specified in the name 101; an arrival time 104 for storing information on a point of time when the transportation facility specified in the name 101 passes or arrives at the point specified in the point 103; and a departure time 105 for storing information on a point of time when the transportation facility specified in the name 101 departs from the point specified in the point 103.
As thus described, the transportation service plan information DB 1 is a database having stored therein points such as stations, bus stops, or taxi stands where passengers get on or off a transportation facility such as railway, bus, or taxi, and points of time when the transportation facility arrives at, departs from, or passes by, the point. Note that, of the points of time of the arrival, departure or passing by, the point of time of the day is a point of time estimated, on the basis of the present service situation and prediction of a future service situation.
Next, the storage unit 155 acquires travel demand information from the travel demand prediction device 120 and stores the acquired travel demand information in a travel demand information DB 2.
Here, the travel demand information DB 2 will be described.
For example, a record 208 illustrated in the drawing indicates that the number of people using transportation from a departure point “point A” to a destination point “point C” (number of travel demands) is estimated to be “1000” in a time zone of “7:30 to 7:35”.
The transportation condition specified in the route selection condition 207 includes respective items of, for example, the time required for transportation from a departure point to a destination point (required time), cost for change of transportation facilities, an additional fare required for the user to pay when using a special transportation facility, and degrees of importance or reference values of the respective items as well. Note that, when no transportation condition is specified in the route selection condition 207, a condition preliminarily stored in the special transportation service planning device 150 is applied as the transportation condition.
As thus described, the travel demand information DB 2 has stored therein, for each transportation from a departure point to a destination point, information of the number of people using the transportation (number of travel demands).
Note that, respective records of the travel demand information DB 2 may be generated by the travel demand prediction unit 121 of the travel demand prediction device 120 as described above, or may be updated by an input unit 161 of the passenger terminal device 160 in a manner such as accepting input of travel demand information from a user of a transportation facility (e.g., accepting via a travel demand information input screen described below) and transmitting the accepted travel demand information to the special transportation service planning device 150 via a communication unit 163.
Here,
As illustrated in the drawing, the travel demand information input screen 1000 has respective items of: a screen frame 1001, a departure point input 1002, a destination point input 1003, a via-point input 1004, and a route search condition input 1005.
Among these, the departure point input 1002 accepts input of information specifying the departure point (e.g., information such as name or location). The destination point input 1003 accepts input of information specifying a destination point (e.g., information such as name or location). The via-point input 1004 accepts input of information specifying a via-point (e.g., information such as name or location). Note that, when not specifying any via-point, there will be accepted input of characters or symbols such as “not specified” indicating no via-point will be specified.
The route search condition input 1005 optionally accepts input of information on a transportation condition. Specifically, the route search condition input 1005 has an additional cost check button 1011, an additional cost reference value input field 1012, an additional cost condition input field 1013, a required-time check button 1014, a required-time input field 1015, a transfer check button 1016, a transfer importance input field 1017, and a transfer evaluation item input field 1018.
The additional cost check button 1011 accepts selection of whether or not to include an additional cost to be paid as a fare of a special transportation facility in the transportation condition. When the additional cost is to be included in the transportation condition, the additional cost reference value input field 1012 accepts input of a reference value, such as the upper limit value or the lower limit value of the additional cost. When the additional cost is to be included in the transportation condition, the additional cost condition input field 1013 accepts input of an inequality sign for specifying the transportation condition.
The required-time check button 1014 accepts selection of whether or not to include required time in the transportation condition. When required time is to be included in a condition, the required-time input field 1015 accepts input of a relative importance against items of other conditions.
The transfer check button 1016 accepts input of selection of whether or not to include ease of transfer in the transportation condition. When ease of transfer is to be included in the condition, the transfer importance input field 1017 accepts input of relative importance against items of other conditions.
The evaluation item input field 1018 accepts selection of an item relating to whether or not to include ease of transfer in the transportation condition. Specifically, the evaluation item input field 1018 has respective items of: a number-of-transfer-times check 1022 relating to the number of transfer times of transportation facilities specified when ease of transfer is to be included in the transportation condition; a walking-distance check 1024 specifying a walking distance when ease of transfer is to be included in the transportation condition; and an elevator check 1026 specified on the premise that an elevator is provided at the transfer point, when ease of transfer is to be included in the transportation condition.
Next, the storage unit 155 illustrated in
Here, the traffic service congestion information DB 3 will be described.
As thus described, the traffic service congestion information DB 3 is a database having stored therein predicted values of congestion for respective traffic services defined in the transportation service plan information DB 1, including, for example, numbers, symbols, or names that uniquely specify traffic services, and predicted values of congestion of the traffic services.
The storage unit 155 acquires congestion information from the traffic-jam prediction device 140 and stores the acquired congestion information in a traffic-jam information DB 4.
Here, the traffic-jam information DB 4 will be described.
a front-end location 401 for storing information indicating the location of the front end of a traffic jam (e.g., name and location information of the point); a tail-end location 402 for storing information indicating the location of the tail end of the traffic jam (e.g., name and location information of the point); a traffic-jam length 403 for storing information indicating the length of the traffic jam; and a travel time 404 for storing information indicating the time required for passing a traffic-jam section.
As thus described, the traffic-jam information DB 4 is a database having stored therein information of the present traffic jam of a road being used by an irregular service and future prediction information of traffic jam.
The storage unit 155 has stored therein a special traffic means information DB 5.
Here, the special traffic means information DB 5 will be described.
For example, a record 508 illustrated in the drawing indicates that a “shared taxi”, which is a special transportation facility using a “road”, performs transportation from a departure point “point A” to a destination point “point E”, and that, when the number of people using the special transportation facility is “six or more” and the fare income is “2000 yen or more”, business operators of transportation facilities are able to provide the special transportation facility.
Next, as illustrated in
The transportation facility specification unit 1561 specifies a transportation facility that performs transportation from the departure point to the destination point.
For example, the transportation facility specification unit 1561 calculates a plurality of combinations of transportation facilities capable of performing transportation from the departure point to the destination point, calculates evaluation values relating to respective transportations by the calculated transportation facilities, and specifies the combination of transportation facilities with the highest calculated evaluation value as the transportation facilities that perform transportation from the departure point to the destination point.
Specifically, the transportation facility specification unit 1561 includes a network model creation unit 156, a travel demand information classification unit 157, and a travel demand calculation unit 158.
The network model creation unit 156 reads the transportation service plan information DB 1, the travel demand information DB 2, and the special traffic means information DB 5, and creates a network model (model representing the relations between departure points, via-points, destination points, and transportation facilities (including special transportation facilities) that perform transportation therebetween), on the basis of the databases which have been read.
The network model of the present embodiment is represented by nodes and links. Among these, a node indicates any of: a departure point, a destination point, or a via-point. A link indicates a transportation facility that performs transportation between the aforementioned points, and an evaluation value relating to the transportation facility. Note that the departure points, the destination points, and the via-points are stored in the transportation service plan information DB 1 and the travel demand information DB 2. A specific example of the network model will be described below.
Note that the aforementioned evaluation value refers to an evaluation value resulting from an evaluation with regard to required time, fare, or number of transfer times of transportation facilities, for example. It is assumed in the present embodiment that the evaluation value refers to an evaluation value relating to the time required by a transportation facility to perform transportation.
Note that the evaluation value is calculated, on the basis of a utility function or the like, which is generally used when evaluating a transportation facility in terms of items such as required-time and fare.
The travel demand information classification unit 157 compares respective records of the travel demand information DB 2, recognizes records having the same departure point, destination point, and route selection condition (transportation condition) and close departure times (e.g., records having the same departure point, destination point, and route selection condition (transportation condition), and departure times within 10 minutes) as a group (hereinafter, referred to as travel demand group), and classifies the records into respective recognized groups.
The travel demand calculation unit 158 extracts, for each travel demand group, a part of a network model (hereinafter, referred to as partial model) from the network model created by the network model creation unit 156. In other words, a partial model is a network model of a transportation route connecting a predetermined departure point and a destination point, within the network model covering the entire transportation network.
The travel demand calculation unit 158 then calculates an evaluation value of each transportation facility in the transportation from the departure point to the destination point, on the basis of the traffic service congestion information DB 3 and the traffic-jam information DB 4 (specifically, on the basis of the partial model). The travel demand calculation unit 158 then calculates the number of people using respective transportation facilities (number of travel demands), on the basis of the calculated evaluation value.
Next, the special traffic service calculation unit 159 calculates a special transportation facility, a transportation section covered by the special transportation facility, and information (hereinafter, referred to as special transportation service information) relating to the time zone in which the special transportation facility performs transportation, on the basis of the number of travel demands calculated by the travel demand calculation unit 158 and the special service provision conditions stored in the special traffic means information DB 5.
Specifically, the special traffic service calculation unit 159 includes the special transportation facility extraction unit 1591 and a special transportation facility specification unit 1592.
The special transportation facility extraction unit 1591 extracts a special transportation facility which is a different transportation facility from the specified transportation facility, and which covers a part of transportation from the departure point to the destination point.
The special transportation facility specification unit 1592 specifies the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point, when the extracted special transportation facility satisfies a predetermined condition (special service provision condition) relating to transportation in the partial section.
For example, the special transportation facility specification unit 1592 calculates the number of people using the extracted special transportation facility and, when the calculated number of people using the special transportation facility exceeds a predetermined value, specifies the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point. Specifically, for example, the special transportation facility specification unit 1592 specifies the transportation facility corresponding to the extracted special transportation facility, and estimates the number of people using the special transportation facility, on the basis of the number of people using the specified transportation facility.
In addition, for example, the special transportation facility specification unit 1592 specifies the transportation facility to be used for transportation from the departure point to the destination point, among the special transportation facilities selected by the special transportation facility selection unit 1512.
Next, the output unit 152 outputs the execution status or execution result, or the like of the process performed by the special transportation service planning device 150.
The output unit 152 includes a special transportation facility information output unit 1521. The special transportation facility information output unit 1521 outputs information on the special transportation facility specified by the transportation facility specification unit 1561.
For example, the special transportation facility information output unit 1521 outputs, for presentation to users, information on the special transportation facility specified, on the basis of the condition input to the transportation condition input unit 1511, to any one or more of: the output unit 152 of the special transportation service planning device 150; an output unit 162 of the passenger terminal device 160; or the output unit 113 of the transportation planning device 110.
For example, the special transportation facility information output unit 1521 outputs information on the special transportation facility in the time zone input to the transportation condition input unit 1511, among the special transportation facilities specified by the transportation facility specification unit 1561.
In addition, for example, the special transportation facility information output unit 1521 outputs information on the special transportation facility that satisfies the conditions input to the transportation condition input unit 1511.
The communication unit 153 communicates with other information processing devices.
Here, the network model in the present embodiment will be described, referring to a partial model.
The partial model 900 includes nodes 901 and links 902. The nodes 901 indicate any of: departure points, destination points, or via-points between the departure points and the destination points. The links 902 represent information including transportation facilities that perform transportation between a departure point and a via-point, between via-points, or between a via-point and a destination point (i.e., connection relation between the nodes 901), and their evaluation values 904 as well. Note that the departure points, the destination points, and the via-points are stored in the transportation service plan information DB 1 and the travel demand information DB 2.
Further, the partial model 900 includes a model 903 relating to a transportation facility from a departure point to a destination point and a model 905 relating to a transportation facility from a via-point to another point. In the example of the drawing, a point D corresponds to the “another point”. In other words, the point D is an “another point” which is not included in the transportation route (via-points) from the point A to the point C, but is reachable by a predetermined transportation facility from a point B which is a via-point therein.
Note that the evaluation value 904 of the link 902 is calculated by subtracting, from the arrival time at each point of each traffic service stored in the transportation service plan information DB 1, the departure time from an immediately preceding point, for example.
Next,
The input unit 161 (transportation condition input unit) accepts input of conditions relating to the departure point, the destination point, and a time zone of the transportation, and optionally, accepts input of conditions relating to at least any of a via-point between the departure point and the destination point, cost relating to transportation from the departure point to the destination point; time required for transportation from the departure point to the destination point, and time required for transfer at the via-point.
The output unit 162 (transportation facility output unit) specifies the transportation facility that performs transportation from the input departure point to the input destination point in the input time zone, and outputs the specified transportation facility.
In addition, the transportation facility output unit specifies the transportation facility that satisfies the input conditions and performs transportation from the input departure point to the input destination point, and outputs the specified transportation facility.
The functions of respective information processing devices described above are realized by hardware of respective information processing devices or by the processors 11 of respective information processing devices which read and execute programs stored in the main storage devices 12 and the auxiliary storage devices 13.
As illustrated at S201 of the drawing, the network model creation unit 156 of the special transportation service planning device 150 first reads all of the entries of the transportation service plan information DB 1 and the travel demand information DB 2, and creates a network model representing the relations between the departure points, the via-points, the destination points, and the transportation facilities stored in the transportation service plan information DB 1 which has been read (S201).
The travel demand information classification unit 157 creates a travel demand group, on the basis of information read at S201 (S202).
The travel demand calculation unit 158 determines whether or not processes of S204 to S207 described below have been performed for all of the travel demand groups generated at S202. In a case where the aforementioned processes have already been performed for all of the travel demand groups, the travel demand calculation unit 158 performs the process of S208 and, when there exist unprocessed travel demand groups, the travel demand calculation unit 158 selects one of such travel demand groups (S204) and performs the process of S205.
At S205, the travel demand calculation unit 158 specifies a departure point, a destination point, and a via-point in a transportation section (hereinafter, referred to as processing section) in a travel demand group selected at S204 to generate (extract), from the network model created at S201, a partial model indicating all of the combinations of transportation means that perform transportation in the processing section (S205). Note that the combinations of transportation means that perform transportation in the processing section may be combinations of different types of transportation means (when, for example, transferring trains and busses), or may be combinations of different vehicles in the same type of transportation means (when, for example, transferring from a train of a certain route to a train of another route).
Next, the travel demand calculation unit 158 specifies all of the transportation facilities that perform transportation in the processing section and calculates an evaluation value of transportation to be performed by the specified transportation facility, on the basis of congestion information (S206). Specifically, for example, the travel demand calculation unit 158 extracts combinations of points in the processing section (e.g., between a departure point and a via-point, between a via-point and a via-point, or between a via-point and a destination point), on the basis of the traffic service congestion information DB 3 or the traffic-jam information DB 4, and the transportation service plan information DB 1, and calculates (updates) the evaluation value of each link in the partial model by calculating the times required between each of the extracted points, respectively.
Specification of the aforementioned transportation facility is performed, for example, by specifying, among transportation facilities that stop at a predetermined point, a transportation facility that arrives at the point after the start time of the departure time zone in the processing section, with an occupancy which is equal to or lower than a constant value at the point. In addition, specification of the aforementioned transportation facility may be performed, on the basis of specification to the passenger terminal device 160 by a user.
Here, an example of specifying a transportation facility and calculating an evaluation value will be described.
Accordingly, as illustrated in the drawing, respective congestion rates of the transportation facilities to be determined are: “250%” for “train 1”, “200%” for “train 2”, and “180%” for “train 3”. Among these transportation facilities, “train 3” turns out to be the transportation facility satisfying the transportation condition indicated by the route selection condition 207 in the record 208 (congestion rate condition). Therefore, “train 3” is determined to be (one of) the transportation facilities for the processing section.
Then, assuming that the transportation facility that departs from “point A” has previously been “train 1”, the departure time from “point A” is changed to “7:50” which is the departure time of “train 3” and is 20 minutes later than “7:30” which is the departure time of “train 1”, whereby the users have to wait for another 20 minutes. Therefore, the previously set evaluation value of “5 minutes” is updated to “25 minutes”.
Next, as illustrated in
The special traffic service calculation unit 159 specifies a transportation facility (including a special transportation facility) from the departure point to the destination point in the processing section, on the basis of the number of travel demands estimated at S207 and the special traffic means information DB 5.
Specifically, for example, the special traffic service calculation unit 159 specifies, among respective special transportation facilities, a special transportation facility for which the number of travel demands estimated at S207 exceeds a predetermined value (e.g., 50 users) as the transportation facility that performs transportation from the departure point to the destination point in the processing section.
The special traffic service calculation unit 159 then generates special transportation service information on the specified transportation facility, and outputs the generated special transportation service information via the output unit 152 or the output unit 162 of the passenger terminal device 160 (S208).
Thereafter, the special transportation facility specification process is terminated (S209).
Here, the screen displayed on the passenger terminal device 160 at S208 will be described.
The selection field 1702 is an input field for selecting a special transportation facility indicated by the corresponding special transportation facility display field 1701. Information on the selected special transportation facility is transmitted to the information processing device managed by a business operator of the transportation facility or the special transportation facility, for example, and the special transportation facility is actually operated, on the basis of the information.
Here, details of the number-of-travel demands calculation process will be described.
Specifically, for example, the travel demand calculation unit 158 acquires respective links in the partial model which has updated the links at S206. In addition, the travel demand calculation unit 158 extracts all of the nodes connected to a plurality of links, among the nodes in the partial model which has updated the links at S206, and calculates an evaluation value of a link (hereinafter, referred to as branch link) connecting all of the extracted nodes to a node linked to the node of interest. In other words, the travel demand calculation unit 158 specifies a plurality of types of transportation facilities that perform transportation from a via-point (branch originating transition point) branching to a plurality of different points (e.g., not only the link connecting “point B” and “point E” illustrated in
Next, at S302, the travel demand calculation unit 158 calculates, on the basis of the special traffic means information DB 5, an evaluation value relating to transportation to be performed by a replacement or an additional special transportation facility of a normal transportation facility, which performs transportation in a partial section of the processing section (e.g., a special transportation facility that performs transportation in a section overlapping with a part of the processing section in which a normal transportation facility performs transportation).
The travel demand calculation unit 158 then compares the evaluation value for the partial section among the evaluation values calculated at S301 with the evaluation value calculated at S302, and specifies and stores the transportation facility having a higher evaluation value.
In other words, the travel demand calculation unit 158 specifies a section for which transportation by a special transportation facility has a better evaluation value than transportation by a normal transportation facility, and stores the special transportation facility that performs transportation in the specified section, together with the section.
Specifically, for example, the travel demand calculation unit 158 extracts, for each of the branch links, all of the special transportation facilities that perform transportation in the branch link, among respective special transportation facilities stored in the special traffic means information DB 5, and calculates the required time, fare, or the like, for performing transportation in the processing section using at least one or more of the extracted special transportation facilities and a normal transportation facility, as the evaluation value of the link. The travel demand calculation unit 158 then compares the calculated evaluation value of the link with the evaluation value of the branch link calculated at S301 and, when the calculated evaluation value of the link is higher, stores the extracted special transportation facility and the section (link).
Note that the evaluation value of a special transportation facility which uses a road (e.g., shared taxi) is calculated, on the basis of duration of road traffic jam. For example, in a case where the type of special transportation facility is “road” (e.g., the type 503 of the special traffic means information DB 5 is “road”), the evaluation value of transportation to be performed by the special transportation facility is a value stored in the travel time 404 of the traffic-jam information DB 4. Alternatively, in a case where the special transportation facility is a transportation facility that uses an infrastructure other than a road (e.g., the type 503 of the special traffic means information DB 5 is “railway”), the evaluation value is calculated, on the basis of a required time calculated, on the basis of transportation to be performed by a transportation facility stored in the transportation service plan information DB 1, or a preliminarily set required time.
Next, at S303, the travel demand calculation unit 158 stores the special transportation facility specified at S302 as a candidate transportation means to be used for transportation from the departure point to the destination point. Specifically, for example, the travel demand calculation unit 158 adds the link stored at S302 to the partial model updated at S206.
Next, at S304, the travel demand calculation unit 158 searches for an optimal transportation route in the processing section, on the basis of the special transportation facility specified at S303. Specifically, for example, the travel demand calculation unit 158 searches for a combination of links with the smallest total sum of evaluation values (i.e., the shortest required time), among the combinations of links from a node of the departure point to a node of the destination point, on the basis of evaluation values of respective links in the partial model generated at S303.
Note that a dynamic programming method or the like, for example, is used for the search of the transportation route. Additionally, in a case where a transportation condition is set for each transportation facility, a search is performed for a transportation route to be covered by a transportation facility satisfying the transportation condition.
Here, an exemplary search for a transportation route at S304 will be described.
Next, as illustrated in S305 of
Specifically, for example, the travel demand calculation unit 158 adds the number of travel demands (e.g., value of the number-of-people-demanding 205 in the travel demand information DB 2) for the transportation facility belonging to the travel demand group selected at S204 and performing transportation from the departure point to the destination point, to the present number of travel demands (the initial value is “0”) for the special transportation facility specified at S303. Accordingly, travel demands (number of travel demands) for the special transportation facility is updated.
As has been described above, the transportation service information providing system 10 of the present embodiment specifies a transportation facility that performs transportation from a departure point to a destination point, extracts a special transportation facility that performs transportation in a partial section of a route from a departure point to a destination point, and specifies and outputs the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point, in a case where the extracted special transportation facility satisfies predetermined conditions relating to transportation in the partial section so that, in a case where transportation has become unavailable in a partial section of the route from the departure point to the destination point, it is possible to specify an appropriate special transportation means that performs transportation in the partial section, on the basis of a predetermined condition, and provide information of the specified special transportation facility. Accordingly, it is possible to provide business operators of transportation facilities and users of the transportation facilities with information on a special transportation service supposed to replace a part of a preliminarily planned transportation service in view of daily variation of demands or unexpected events (in case of service failure).
For example, a user of a transportation facility may travel from a departure point to an intermediate point using a special transportation facility and travel from the intermediate point to a destination point using a preliminarily planned transportation facility. In addition, a transportation facility manager can provide a user with an appropriate special transportation facility even when the user of the transportation facility has a demand for a medium or long distance travel.
In addition, the transportation service information providing system 10 of the present embodiment calculates a plurality of combinations of transportation facilities capable of performing transportation from a departure point to a destination point, calculates evaluation values relating to respective transportations by the calculated transportation facilities, and specifies the combination of transportation facilities with the highest calculated evaluation value as the transportation facilities that perform transportation from the departure point to the destination point, so that it is possible to provide a combination of appropriate transportation means that performs transportation from the departure point to the destination point. Accordingly, for example, it is possible to provide business operators of transportation facilities and users of the transportation facilities with a combination of appropriate transportation means.
In addition, the transportation service information providing system 10 of the present embodiment calculates the number of people using the extracted special transportation facility and, when the calculated number of people using the special transportation facility exceeds a predetermined value, specifies the special transportation facility as the transportation facility to be used for transportation from the departure point to the destination point, so that, for example, business operators of transportation facilities can grasp a special transportation facility expected to be demanded by users. In addition, users of transportation facilities also can grasp a special transportation facility which is likely to be operated.
In addition, the transportation service information providing system 10 of the present embodiment specifies a transportation facility corresponding to a special transportation facility and calculates the number of people using the special transportation facility, on the basis of the number of people using the specified transportation facility, so that, even when a special transportation facility may be operated in place of the original transportation facility, it is possible to appropriately estimate the number of people using the special transportation facility and thereby provide an appropriate special transportation facility.
In addition, the transportation service information providing system 10 of the present embodiment accepts input of conditions relating to a departure point, a destination point, and a time zone of transportation, and optionally, accepts input of conditions relating to at least any of a via-point between the departure point and the destination point, cost relating to transportation from the departure point to the destination point, time required for transportation from the departure point to the destination point, and time required for transfer at the via-point, and outputs information on the special transportation facility specified, on the basis of the input conditions, so that it is possible to provide, for example, business operators of transportation facilities and users of the transportation facilities with an appropriate special transportation facility that satisfies a desired condition.
In addition, the transportation service information providing system 10 of the present embodiment accepts selection of an extracted special transportation facility and specifies a transportation facility to be used for transportation from the departure point to the destination point among the selected special transportation facilities, so that it is possible to provide, for example, only the special transportation facility desired by users of transportation facilities.
