Referring to
The service providing server 100, the user terminal 200, and a plurality of driver terminals 300_1 to 300_6 are connected to each other through a network.
The service providing server 100 may include a call control module 110, a ride group determination module 120, a general call module 130, and a walking call module 140.
Also, the application 210 is provided in the user terminal 200, and a plurality of applications 310_1 to 310_6 are provided in a plurality of driver terminals 300_1 to 300_6, respectively.
When describing common operational and technical characteristics of a plurality of driver terminals 300_1 to 300_6, a plurality of driver terminals 300_1 to 300_6 are collectively referred to as a driver terminal 300. Although the number of the driver terminals 300 is shown as 6, this is for convenience of explanation, and the number of the driver terminals 300 is not limited thereto.
Hereinafter, a driver using each of the driver terminals 300_1 to 300_6 may be referred to as a driver 1 to a driver 6. The driver 1 to the driver 6 may represent a person operating a taxi using a call dispatch according to the ride positioning service according to an exemplary embodiment of the present disclosure.
The starting position and the destination of the call request may be input through the application 210 of the user terminal 200 (
In the following, the starting position is the starting point of the path that the user wants to move through the call request. Also, the destination is an end point of the path that the user wants to move through the call request.
The ride point is a position determined through the ride positioning service provided by the service providing server 100, and means a position in which the user rides a taxi to move from the starting position of the call request to the destination.
The general ride point may be determined through the service providing server 100 as a position where the user may ride a taxi directly without moving on foot from the starting position of the call request.
The walking ride point may be determined through the service providing server 100 as a position where the user can ride a taxi after moving a predetermined distance on foot from the starting position of the call request.
The call control module 110 receives a signal indicating the starting position and the destination along with the call request from the user terminal 200 (S100).
The call control module 110 may receive a signal indicating a position in which the user terminal 200 is positioned at a specific time from the user terminal 200. The call control module 110 may determine the position in which the user terminal 200 is positioned at a specific time point as the starting position.
Here, the specific time point may be any point in the period from the time when the user terminal 200 receives the starting position input from the user to the time when the service providing server 100 dispatches the call to the driver terminal 300.
The call control module 110 may determine the starting position as a general ride point (S200).
According to the ride positioning service according to an exemplary embodiment of the present disclosure, the user may make the call request by use of the position input by the user as the starting position as the ride point just like the general taxi call request, so that the starting position may be determined as the general ride point.
For example, when the call control module 110 determines the current position of the user terminal 200 as the starting position, the current position of the user terminal 200 may be determined as the general ride point.
The ride group determination module 120, for a plurality of driver terminals 300_1 to 300_6, determines a walking ride group including the driver terminal in which the road to which the starting position belongs is a non-preference option, and a general ride group including the driver terminal in which the road to which the starting position belongs is not the non-preference option (S300).
If the driver 1 to the driver 6 do not prefer a specific road type, the driver 1 to the driver 6 may select the corresponding road as the non-preference option and input it to each of the driver terminals 300_1 to 300_6. The ride group determination module 120 may receive the non-preference option for each terminal from each of driver terminals 300_1 to 300_6.
The specific road type may include certain types of roads such as pedestrian lanes, bike lanes, one-way streets, alleys, etc and certain types of road zones such as no-parking zones, children protection zones, bus stops, etc.
For example, if the driver using driver terminal 300_1 selects a one-way street as the non-preference option and the starting position of the call request belongs to the one-way street, the ride group determination module 120 may include the driver terminal 300_1 in the walking ride group.
Here, there may be a plurality of driver terminals forming each ride group.
Hereinafter, a driver terminal forming the walking ride group is represented by the driver terminals 300_1 to 300_3, and the driver terminal forming the general ride group is represented by the driver terminals 300_4 to 300_6. However, this is for convenience of description, and the number of driver terminals forming each walking ride group and general ride group is not limited to three, and may be an integer of 1 or more.
The call control module 110 may determine whether the weather information of the user terminal 200 corresponds to a specific weather condition (S400).
The specific weather condition may be determined based on the position of the user terminal 200 at a specific point in time. Here, the specific point in time may be any point in the period from the point in time when the service providing server 100 receives the call request from the user terminal 200 to the point in time when the call is dispatched to the driver terminal 300.
The call control module 110 may check the weather at the position of the user terminal 200 and determine that it is raining, which is one of the specific weather conditions, when it rains. The specific weather condition may include, in addition to the raining, an inclement weather such as snow and/or hail, heat waves, or extreme cold.
If the weather information of the user terminal 200 corresponds to the specific weather condition, the general call module 130 may determine the expected fare expected to be required when moving by the taxi from the general ride point to the destination based on the taxi fare information and the path to move by the taxi from the general ride point to the destination (S410).
For example, when it rains at the position of the user terminal 200, the general call module 130 may derive the path so that the entire moving distance from the same general ride point as the starting position to the destination may be moved by the taxi without moving by foot.
The taxi fare information may include a basic fare, a taxi fare rate, and the like.
The general call module 130 may derive the path to move by the taxi from the general ride point to the destination based on the distance from the ride point to the destination, the road usage fee, the estimated required time, and the like.
The general call module 130 may transmit a signal indicating the determined expected fare to the user terminal 200 (S420).
The general call module 130 may request the call to the driver terminals 300_4 to 300_6 forming the general ride group based on the general ride point (S430).
Because the driver terminals 300_1 to 300_3 forming the walking ride group use the road to which the starting position belongs as the non-preference option, the call request to ride the taxi at the starting position, which is the general ride point, is not received. Accordingly, only the driver terminals 300_4 to 300_6 forming the general ride group may receive the call request.
The general call module 130 may dispatch the call to the driver terminal that has accepted the call request (S440).
If there is one driver terminal that has accepted the call request, the general call module 130 may dispatch the call to one driver terminal that has accepted the call request.
In the call dispatch (S440), if a plurality of driver terminals 300_4 to 300_5 accept the call request, the general call module 130 may predict the times to arrive at the general ride point when moving by the taxi from each position of a plurality of driver terminals 300_4 to 300_5 to which the call is accepted.
The general call module 130 may receive a signal indicating the position in which a plurality of driver terminals 300_4 to 300_5 are positioned at a specific time point from a plurality of driver terminals 300_4 to 300_5. Here, the specific time point may be any point in the period from the time when the service providing server 100 receives the call request to the time at which the call is dispatched to one of the driver terminals 300.
The general call module 130 may determine the driver terminal to dispatch the call according to a result of comparing the estimated arrival times of each of driver terminals 300_4 to 300_5 that have accepted the call.
For example, when moving by the taxi from the current position of the driver terminal 300_4 to the general ride point, if the expected arrival time to the walking ride point is 10:00 and the expected arrival time of the driver terminal 300_5 is 10:15, the general call module 130 may dispatch the call to the driver terminal 300_4, which has the earlier expected arrival time.
If the weather information of the user terminal 200 does not correspond to the specific weather condition, the walking call module 140 may determine a plurality of ride candidate positions according to the size of the road in the area within a certain range and the path to move by the taxi to the destination based on the starting position (S500).
For example, if the weather at the position of the user terminal 200 is sunny, the user may consider moving from the starting position to the area within a certain range by walking. The walking call module 140 may determine a plurality of ride candidate positions for designating the walking ride point in the area within a predetermined range based on the starting position.
The predetermined range and the number of the ride candidate positions may be received from the user terminal 200, or may be determined in advance by the service providing server 100 as initial information. For example, three ride candidate positions may be determined at a distance within a 500 m radius based on the starting position.
In
For example, the walking call module 140 may derive the specific position on the road, in which the size of the road is two or more round trip lanes, as a preliminary ride position to facilitate the entry of the vehicle.
The number of the preliminary ride positions may be greater than or equal to the number of the ride candidate positions.
The walking call module 140 may derive a plurality of paths to move by the taxi from a plurality of preliminary ride positions to the destination, and determine the ride candidate position according to a result of comparing the distances of each of the derived paths with each other (S520).
The walking call module 140 may determine the preliminary ride position including the shortest distance to the destination as the ride candidate position, giving preference to the preliminary ride position including the longest distance to the destination.
For example, three positions may be determined as the ride candidate positions in the order of the closest distance to the destination among ten preliminary ride positions.
The walking call module 140 may determine a plurality of expected fares expected to be required when moving by the taxi from each ride candidate position to the destination based on the taxi fare information and the paths traveled by the taxi from each of ride candidate positions to the destination (S600).
The walking call module 140 may transmit a signal indicating the position of each ride candidate position and the expected fare determined for each ride candidate position to the user terminal 200, and may determine one selected position as the walking ride point if a signal indicating one position selected among a plurality of ride candidate positions is received from the user terminal 200 (S700).
Referring to
The user may select one position among a plurality of ride candidate positions displayed through the application 210 to be input to the user terminal 200. The user terminal 200 may transmit a signal indicating one position selected by the user among a plurality of ride candidate positions to the walking call module 140.
In
The walking call module 140 may determine the expected fare expected to be required when moving by the taxi from the walking ride point to the destination based on the taxi fare information and the path to travel by the taxi from the walking ride point to the destination.
The walking call module 140 may determine the expected fare expected to be required when moving by the taxi from the general ride point to the destination based on the taxi fare information and the path to travel by the taxi from the general ride point to the destination.
Referring to
The user may select one position among the walking ride point and the general ride point displayed through the application 210 to be input to the user terminal 200.
The walking call module 140 may dispatch the call to the driver terminal that accepts the call request (S900).
If the position selected by the user is the walking ride point, the walking call module 140 may request the call to each of the driver terminals 300_1 to 300_6 forming the walking ride group and the general ride group based on the ride point received from the user terminal 200. At the instant time, each of the driver 1 to the driver 6 may accept the call request through the applications 310_1 to 310_6 of the driver terminals 300_1 to 300_6.
Alternatively, if the position selected by the user is the general ride point, the walking call module 140 may request the call to each of the driver terminals 300_4 to 300_6 forming the general ride group based on the ride point received from the user terminal 200. At the instant time, the driver 4, the driver 5, and the driver 6 may each accept the call request through the applications 310_4 to 310_6 of the driver terminals 300_4 to 300_6.
If there is one driver terminal that has accepted the call request, the walking call module 140 may dispatch the call to one driver terminal that has accepted the call request.
In the call dispatch (S900), when a plurality of driver terminals 300_4 to 300_5 accept the call request based on the general ride point, the walking call module 140 may predict the times to arrive at the general ride point when moving by the taxi from each position of a plurality of driver terminals 300_4 to 300_5 to which the call is accepted.
The walking call module 140 may receive, from a plurality of driver terminals 300_4 to 300_5, a signal indicating the position in which a plurality of driver terminals 300_4 to 300_5 are positioned at a specific time point. Here, the specific time point may be any point in the period from the time when the service providing server 100 receives the call request to the time at which the call is dispatched to one of the driver terminals 300.
The walking call module 140 may determine the driver terminal to dispatch the call based on a result of comparing the estimated arrival times of each of driver terminals 300_4 to 300_5 that have accepted the call.
The walking call module 140 predicts the time to arrive at the walking ride point by walking from the starting position (S910).
Because the walking ride point does not match the starting position and the ride point, the walking call module 140 derives the walking path from the starting position to the walking ride point. The walking call module 140 may predict the time for the user to arrive by the walking to the walking ride point based on the walking path from the starting position to the walking ride point.
The walking call module 140, if a plurality of driver terminals 300_1 to 300_2 accept the call, may predict the times to arrive at the walking ride point when moving by the taxi from each position of a plurality of driver terminals 300_1 to 300_2 that have accepted the call to the walking ride point (S920).
The position of each of driver terminals 300_1 to 300_2 that have accepted the call may be determined based on an arbitrary time in the period from the time when the present service providing server 100 receives the call request to the time when the call is dispatched to one of the driver terminals 300_1 to 300_2.
The walking call module 140 may determine a plurality of error times between the times predicted to arrive at the walking ride point by moving on foot and each of the times predicted to arrive at the walking ride point of a plurality of driver terminals that have accepted the call, and dispatch the call to one driver terminal based on a plurality of error times (S930).
In other words, the walking call module 140 may dispatch the call to the driver configured for minimizing the difference between the time that the user arrives at the walking ride point and the time the taxi operated by the driver drives arrives at the walking ride point.
For example, it may be assumed that the walking call module 140 requests the call to the driver terminals 300_1 to 300_3 and receives the call acceptance from the driver terminals 300_1 to 300_2. In the example, it may be predicted that the predicted time for the user to arrive at the walking ride point by the walking is 10:00, the predicted time for the driver 1 to travel by the taxi to arrive at the walking ride point is 10:15, and the predicted time for the driver 2 to travel by the taxi to arrive at the walking ride point is 10:05. At the instant time, because the error time of the driver terminal 300_1 of the driver 1 is 15 minutes and the error time of the driver terminal 300_2 of the driver 2 is 5 minutes, the walking call module 140 may dispatch the call to the driver terminal 300_2 with the small error time.
When one of a plurality of driver terminals 300 is dispatched for the call request based on the general ride point, the general call module 130 or the walking call module 140 may provide the arrival information of the taxi dispatched through the application 210 of the user terminal 200.
When the driver terminal 300_2 is dispatched for the call request based on the walking ride point, the walking call module 140 may provide the walking path of the user and the arrival information of the dispatched taxi through the application 210 of the user terminal 200.
The arrival information of the dispatched taxi may include the name of the driver of the dispatched taxi, the vehicle number of the dispatched taxi, the vehicle type of the dispatched taxi, and the estimated arrival time of the dispatched taxi.
