Embodiments of the invention relate to the tracking and analysis of drivers within a fleet of vehicles.
Operators of fleets of vehicles desire tools to track and analyze their fleets. These fleets comprise a plurality of vehicles that are commonly associated. For example, a fleet of vehicles could be a commercial delivery service, a city police department, a state emergency response team, a military unit, or the like. Fleets require extensive costs for maintenance of the vehicles and training of the drivers. The fleet also represents a litigation liability for the operator due to the potential for property damage and injury that can be caused by the drivers. Therefore, operators desire detailed information on their drivers' activities while operating the vehicles.
Systems of the prior art utilize a vehicle-tracking device that is disposed in the vehicle. The vehicle-tracking device monitors the location and status of the vehicle and transmits this information to a central location. The central location may then populate a map with location and incident information and may also track incidents related to each driver.
These systems of the prior art have several drawbacks. First, any video of the incident is not associated with the incident in the system, or must be manually located and extracted. Second, incidents are difficult to review due to the lack of associated video. Third, the simple analysis performed by the systems of the prior art provides little meaningful information.
Embodiments of the invention solve the above-mentioned problems by providing a system, a computer program, and a method of fleet tracking and analysis. Embodiments of the invention associate video data from a video camera with the incident. Embodiments of the invention then populate the map with segments of the video to aid in the review of the incident by a supervisor. Embodiments of the invention perform detailed analysis of the drivers by comparing the drivers against other drivers in the fleet, across other fleets, across other similar drivers of other fleets, etc. Embodiments of the invention therefore provide improved analytical tools for operators of the fleet.
A first embodiment of the invention is directed to a system for tracking a fleet of vehicles. The system includes a monitoring engine for receiving information from a vehicle-tracking device associated with a vehicle of the fleet, wherein at least a portion of said information is incident information that is associated with an incident detected by the vehicle-tracking device. The system also includes a mapping engine for displaying, to a user, an icon indicative of the incident on a map, wherein the icon is located on the map in a location corresponding to an incident location. The system also includes a video repository engine for receiving video data from a video camera associated with the vehicle, said video repository engine acquiring an incident video based upon at least a portion of said video data. The mapping engine associates the incident video with said icon displayed on the map such that the user may select and view the incident video.
A second embodiment of the invention is directed to a system for analyzing a driver associated with a fleet of vehicles. The system includes a monitoring engine for receiving information from a vehicle-tracking device associated with a vehicle of the fleet that is associated with the driver, wherein at least a portion of said information is an incident information associated with an incident detected by the vehicle-tracking device. The system also includes a driver analysis engine for obtaining the incident information associated with a plurality of drivers, wherein the driver is one of said plurality of drivers. The driver analysis engine also analyzes the incident information associated with the driver to generate a driver profile. The driver analysis engine also compares the driver profile for the driver with corresponding driver profiles for the plurality of drivers.
A third embodiment of the invention is directed to a system for tracking a fleet of vehicles and analyzing a driver associated with the fleet of vehicles. The system includes a monitoring engine for receiving information from a vehicle-tracking device associated with a vehicle of the fleet, wherein at least a portion of said information is incident information that is associated with an incident detected by the vehicle-tracking device. The system also includes a mapping engine for displaying, to a user, an icon indicative of the incident on a map, wherein the icon is located on the map in a location corresponding to an incident location. The system also includes a video repository engine for receiving video data from a video camera associated with the vehicle. The video repository engine acquires an incident video based upon at least a portion of said video data. The mapping engine associates the incident video with said icon displayed on the map such that the user may select and view the incident video. The system also includes a driver analysis engine for obtaining the incident information associated with a plurality of drivers, wherein the driver is one of said plurality of drivers. The driver analysis engine analyzes the incident information associated with the driver to generate a driver profile. The driver analysis engine also compares the driver profile for the driver with corresponding driver profiles for the plurality of drivers.
A fourth embodiment of the invention is directed to a non-transitory computer readable medium having a computer program stored thereon. The computer program instructs at least one processing element to perform the at least a portion of the steps discussed herein.
A fifth embodiment of the invention is directed to a computerized method for tracking a fleet of vehicles and/or analyzing a driver of the fleet of vehicles. The method comprises at least a portion of the steps discussed herein.

Embodiments of the invention are broadly directed to a system 10 for providing an operator, supervisor, or administrator of a fleet 12 with tools to maximize the safety, cost efficiency, and effectiveness of the fleet 12. Embodiments of the invention improve safety by identifying weaknesses and other characteristics of a driver 14 that can be improved to reduce the likelihood and severity of accidents. Embodiments of the invention improve cost efficiency by reducing fuel and other maintenance costs, providing exculpatory evidence in the case of litigation, etc. Embodiments of the invention improve effectiveness of the fleet 12 by recommending training or changes in behavior of the drivers 14.
Before discussing embodiments of the invention in depth, a few terms will be discussed so as to orient the reader. It should be noted, however, that the terms discussed herein provide exemplary discussions that should not be considered constraining on the construction of said terms.
As used herein, a “fleet” is an association of vehicles 16, machinery, or other devices. Vehicles 16 of the fleet 12 can be operated primarily on land, primarily in water, primarily in the air, primarily in space, etc. Typically, a fleet 12 is united in a common purpose, location, or control. For example, the fleet 12 may all be owned and/or operated by a single company, organization, or government entity. Examples of fleets 12 include a group of commercial shipping vehicles, a group of taxi cabs owned by a company in a certain city, a company's commercial shipping barges, a school district's school buses, law enforcement vehicles belonging to a certain municipality, a squadron of military airplanes, etc. For the sake of clarity, the fleet 12 will primarily be referred to as a fleet 12 of law enforcement vehicles throughout the remainder of this application; however, this is only exemplary.
As used herein, a “driver” is a driver 14 of the vehicle 16, an operator of the vehicle 16, a pilot of the vehicle 16, a captain of the vehicle 16, another crew member associated with the vehicle 16, etc. The driver 14 may be co-located with the vehicle 16, or may be remote. For example, a driver 14 in a fleet 12 of unmanned aerial vehicles may be located hundreds of miles away from the vehicle 16. Typically, the driver 14 is responsible for the movement of the vehicle 16 through its environment. Generally speaking, embodiments of the invention track and evaluate how the driver 14 moves the vehicle 16 through its environment.
Turning to the figures, general components associated with the system 10 are depicted in
As the vehicle 16 is operating, the vehicle-tracking device 18 is acquiring information regarding various aspects of the vehicle 16 such as location, speed, acceleration, the use of brakes, the use of blinkers, and the like. Abnormal behaviors or conditions may be detected by the vehicle-tracking device 18 (known as “incidents,” discussed more below). The vehicle-tracking device 18 communicates with a monitoring engine. The vehicle-tracking device 18 sends information to the monitoring engine such as location, speed, incident information, etc. In embodiments of the invention, communication between the vehicle-tracking device 18 and the monitoring engine happens substantially in real time. A mapping engine generates a display of a map 22 on a display for the user. The mapping engine generates an icon 24 to display on the map 22. The icon 24 is indicative of a location and/or a status of the vehicle 16, based upon the information received by the monitoring engine from the vehicle-tracking device 18. The location of the icon 24 on the map 22, color, written information, and the like may be periodically or continuously updated based on newly received information from the vehicle-tracking device 18.
Upon the vehicle 16 traveling or returning to an upload location (such as a facility associated with the fleet 12), a video repository engine communicates with the video camera 20 disposed in the vehicle 16. The video repository engine receives, retrieves, or otherwise acquires video data from the video camera 20 in the vehicle 16. Typically, the video repository engine acquires the video data at a time later than the incident. For example, in the case of a law enforcement vehicle, when the law enforcement vehicle returns to the central law enforcement station, the video repository engine may communicate with the video camera 20 (or other device) to download the recorded video data. Alternatively, recorded video data may be transmitted to the video repository engine in substantially real time as the incident is occurring (e.g., “live streamed”), at a time later than the incident but prior to the vehicle 16 returning to the upload location, or in response to a user request to download the video data.
A driver analysis engine acquires data regarding the performance of the driver 14 from the monitoring engine. The driver analysis engine may also receive information from the video repository engine and/or the mapping engine. The driver analysis engine compares the information related to the driver's performance against historical information for the driver 14, established standards, and comparisons to other drivers 14. Based upon this analysis, the driver analysis engine may present information for a supervisor to review, recommend training, etc.
In some embodiments, the vehicle-tracking device 18 communicates only with the monitoring engine and not with any of the other components. In other embodiments, the vehicle-tracking device 18 communicates with the recording device manager 28 to send incident information, location information, and the like. In these embodiments, the recording device manager 28 may instruct the video camera 20 or other recording device to save the information from vehicle-tracking device 18. In addition, the video camera 20 or other recording device manager 28 may associate the information with the video data being recorded. In still other embodiments, the vehicle-tracking device 18 communicates directly with the video camera 20 or other recording device to provide incident information and/or current information about the status of the vehicle 16. In yet further embodiments, the vehicle-tracking device 18 communicates with the driver computing device 30, such that information from the vehicle-tracking device 18 is displayed to the driver 14 in the vehicle 16. This allows the driver 14 to make adjustments to driving habits to avoid future incidents, be able to discuss prior incidents with a dispatcher or supervisor while still driving, etc. The driver computing device may also display the map 22 to the driver 14.
It should be noted that while the vehicle-tracking device 18, the vehicle-mounted video camera 26, the recording device manager 28, and the driver computing device 30 are depicted in
The components of the vehicle-tracking device 18 are schematically illustrated in
The accelerometer 40 independently detects accelerations of the vehicle 16. The detected accelerations can be vertical (e.g. traveling over a bump or pothole too fast), horizontal forward (e.g. the driver 14 is accelerating or braking too quickly), and horizontal lateral (e.g. the driver 14 is taking turns at a high rate of speed). Accelerations that surpass a certain threshold are recorded and transmitted as incidents. The threshold may be fixed (e.g. a maximum safe acceleration rate of the vehicle 16), variable based upon location (e.g. within the posted speed limit, as determined by a map associated with the location element 42), variable based upon conditions (e.g. a very sudden deceleration or impact may be indicative of a vehicle crash), or the like.
The location element 42 determines the location of the vehicle 16. In some embodiments, the location element 42 utilizes the global positioning system (GPS) to determine location. The location element 42 determines the GPS location of the vehicle-tracking device 18 (and thereby the vehicle 16). The location element 42 transmits information indicative of the location to the processing element 48. The location information may then be stored on the memory element 50 of the vehicle-tracking device 18 and/or be transmitted to the recording device manager 28 and/or monitoring engine via the communications element 46. The location element 42 may also determine and record the time of the incident. This information can, like the incident information and other data, be further saved as video metadata, as described above. The location information and time information provide further authentication to the incident information.
The vehicle status element 44 interfaces with the vehicle 16 via the vehicle interface 38 and an on-board diagnostics (OBD) port in the vehicle 16 to determine various statuses of the vehicle 16. For example, the vehicle status element 44 may determine when and if the brakes are applied, the blinker is engaged, the engine is running, the headlights are on, the gas pedal is depressed, etc. The vehicle status element 44 may also determine levels and warnings displayed in the vehicle 16, such as the “check engine” light, the fuel level, the emergency brake, etc. The vehicle status element 44 provides operating information such as idle time, travel time, working time, etc. In some embodiments, the vehicle status element 44 stores this information. In some embodiments, the vehicle status element 44 records this information in connection with an incident (“incident information”). In other embodiments, the vehicle status element 44 records all of this information for later use and/or communicates at least a portion of the information to the recording device manager 28 for association with the recorded video data.
The communications element 46 of the vehicle-tracking device 18 transmits incident information and other information to the monitoring engine. In some embodiments, the vehicle-tracking device 18 sends continuous or substantially continuous information to the monitoring engine regarding the vehicle's location. In some embodiments, the vehicle-tracking device 18 sends incident information regarding an incident detected by the vehicle-tracking device 18. In still other embodiments, certain incidents are communicated if they are above a threshold severity. For example, the communications element 46 may send incident information to the monitoring engine for vehicular accidents and vehicle breakdowns but will not send incident information for other unsafe driving incidents.
In some embodiments of the invention, the communications element 46 is communicatively linked to the recording device manager 28 and/or the driver computing device 30, such that messages can be sent therebetween. In some embodiments, the communications element 46 is also communicatively coupled, either directly or indirectly, with one or more other elements of the system 10. In addition to the incident information, the vehicle-tracking device 18 may transmit information indicative of a status. The status could include information such as vehicle-tracking device power on, vehicle power on, vehicle driving, error detected, error not detected, name of the driver 14 (based, in some embodiments, upon the proximity tag system discussed below), one or more identifiers (such as model number or serial number) associated with vehicle-tracking device 18, etc. All of this information can be stored as metadata for video recorded by one or more video cameras 20, or displayed in real time by one or more displays associated with the system 10.
The communications element 46 of the vehicle-tracking device 18 may be wirelessly connected to the recording device manager 28, the driver computing device 30, and/or the monitoring engine. The communications element 46 transmits the incident information and/or status substantially in real time (as defined below). Typically, the communications element 46 will operate via the mobile broadband network, Bluetooth technology, Wi-Fi technology, or the like. The communications element 46 may alternatively or in addition be connected via a communications wire to the recording device manager 28, the driver computing device 32, and/or video camera 20.
The incident information may be stored in metadata of the recorded video data from the at least one video camera 20. In some embodiments, the storage of the metadata may be done in substantially real time as the vehicle 16 is operating. In other embodiments, the storage of the metadata is performed automatically or semi-automatically after the vehicle 16 returns to the upload location, discussed below.
Metadata associates one set of data with another set of data. The metadata may be embedded in the captured video data, stored externally in a separate file that is associated with the captured video data, otherwise associated with the captured video data, or all of the above. Embedding the incident information into the same file with the captured video data can be advantageous because it allows the metadata to travel as part of the data it describes. In some such embodiments, metadata is associated with a particular frame or frames of the video data. This is advantageous where, for example, the same video file contains more than one incident. In other such embodiments, the metadata is associated with the video file as a whole. Externally stored metadata may also have advantages, such as ease of searching and indexing. The metadata may also be stored in a human-readable format, such that a user can access, understand, and edit the metadata without any special software. Some information stored in the metadata may be relatively static, such as a manufacturer name and model of the vehicle-tracking device 18, an identifier assigned to the specific vehicle-tracking device 18 by a law enforcement agency, etc.
The user may also selectively superimpose the incident information, the status and/or the relatively static information over the recorded video data. This may aid in the presentation of the video in a court or other judicial body. For example, if the vehicle 16 is a commercial vehicle, the operating company may present a video of a traffic accident in court with the relevant incident information and/or status superimposed thereon. The video, along with the superimposed status and/or incident information may be visually appealing and persuasive to a fact finder that the driver 14 was not at fault for the accident. As another example, in corrective training generated for the driver 14, embodiments of the invention may utilize actual video data from the driver's history with superimposed information to demonstrate certain information to the driver 14. Still further embodiments of the invention may include a driving simulation in which the driver 14 is invited to recreate the event and attempt to improve their performance. For example, if a driver 14 struck an animal while driving, the driving simulation may use or base a simulation on the associated video data (along with the superimposed information) and allow the driver 14 to recreate the event through simulation such that the driver 14 can be better prepared to avoid striking animals in the future.
Some embodiments of the invention comprise a proximity tag system for authenticating the devices, cameras, and drivers 14 associated with the incident. The proximity tag system comprises a plurality of proximity tags 34 and at least one proximity tag reader 52. Proximity tags 34 are any devices that radiate an identifying signal, herein referred to as the proximity tag identifier, that can be read by a corresponding reader such as the proximity tag reader. Proximity tags 34 can be active (meaning that they periodically broadcast their identifier), assisted passive (meaning that they broadcast their identifier only when interrogated by a signal from the reader), or passive (meaning that they have no power source and are illuminated by a signal from the proximity tag reader in order to radiate their identifier). Other forms of proximity tags are also possible. Proximity tag identifier may be preprogrammed into proximity tags 34, or may be field-programmable, such that the identifier is assigned by the user when the proximity tag 34 is deployed. One common form of proximity tag system is the radio-frequency identification (RFID) tag and the corresponding RFID reader. Another form of proximity tag system utilizes a challenge-response protocol to avoid the spoofing of a proximity tag identifier. An exemplary proximity tag system is described in U.S. patent application Ser. No. 14/517,368, filed Oct. 17, 2014, and entitled “FORENSIC VIDEO RECORDING WITH PRESENCE DETECTION,” which is incorporated by reference herein in its entirety.
In embodiments of the invention, the driver 14 uses a proximity tag 34 that contains a proximity tag indicator specific to that driver 14 to authenticate the name, fleet 12, and/or status of the specific driver using the recording device manager 28 and/or the vehicle-tracking device 18. The proximity tag 34 may be located within a proximity card held by the driver, within the badge worn by the driver, on a watch or a belt worn by the officer, within a key used by the driver to start the vehicle, etc. There may also be a proximity tag 34 in the vehicle-tracking device 18 and/or the video cameras 20. The proximity tag reader reduces work to be performed at a later time to associate the recorded video data and incident information with the specific driver.
The recording device manager 28, as illustrated in
Typically, the recording device manager 28 detects when one video camera 20 begins recording, and then instructs all other associated devices to begin recording. The recording device manager 28 may also send information indicative of a time stamp to the various recording devices for corroborating the recorded data. In embodiments of the invention, the recording device manager 28 instructs all associated video cameras 20 to begin recording upon the receipt of a signal from the vehicle-tracking device 18 that an incident has been detected. This helps to ensure that the incident is captured as thoroughly as possible. For example, the vehicle 16 may have one forward-facing video camera that is continuously recording and multiple externally mounted video cameras facing in multiple directions that remain idle until an incident is detected. Upon the detection of an incident by the vehicle-tracking device 18, the recording device manager 28 instructs these secondary video cameras to begin recording, such that conditions around the vehicle 16 may be observed. The video cameras may also be continuously recording and dumping a set amount of time worth of video. The recording device manager 28 may instruct the video camera to store that amount of video data instead of dumping it.
Various methods of embodiments of the invention as performed by various engines will now be discussed. In some embodiments, a non-transitory computer readable storage medium having a computer program stored thereon may instruct at least one processing element to implement the steps of at least one of the described methods. The non-transitory computer readable storage medium may be located within a server device, the recording device manager 28, the vehicle-tracking device 18, and/or within a generic computing device.
In Step 400, the monitoring engine detects the vehicle-tracking device 18. Step 400 may be performed during the powering on of the vehicle-tracking device 18 before the vehicle 16 leaves the vicinity. Upon detection, the monitoring engine may request additional information from the vehicle-tracking device 18 such as a current status and/or location. It should be appreciated that the monitoring engine may detect and track many vehicle-tracking devices 18 simultaneously (of the same or multiple fleets 12).
In Step 402, the monitoring engine receives location information for the vehicle-tracking device 18. In Step 404, the monitoring engine sends this information to the mapping engine so that the mapping engine can populate and/or move the icon 24 associated with the vehicle 16.
In Step 406, the monitoring engine receives incident information from the vehicle-tracking device 18. In some embodiments, the received incident information is minimal. For example, the information may include that there is an incident, a location of the incident, and a type of incident, but without excessive details. This minimizes the amount of data transferred while still alerting the monitoring engine (and by extension an operator or dispatcher observing the monitoring engine and/or the map 22) of the incident. The type of incident may be determined by the vehicle-tracking device 18, the driver computing device 30, the recording device manager 28, or other component. The type of incident is indicative of the nature of the incident and/or the severity of the incident. Examples of types of incidents include speeding, harsh braking, rapid acceleration, harsh cornering, failure to use a vehicular system (such as the brakes, blinker, wipers, etc.) vehicular collision, vehicular theft, vehicular breakdown, tampering with the vehicle-tracking device 18, operation of the vehicle by an unauthorized driver, operation of the vehicle outside work hours, operation of the vehicle outside a certain geographic area, the passing of a certain time interval, the passing of a certain geographic waypoint, etc. The type of incident may also include a severity level of the incident. For example, speeding in excess of twenty miles per hour over the posted speed limit may have a classification such as “imminently dangerous speeding” or “speeding level 3.” In some embodiments, the operator or dispatcher may request additional information from the vehicle-tracking device 18 if additional details are needed. In Step 408, this information is sent to the mapping engine for the creation or updating of the icon 24. In Step 410, the information is sent to the driver analysis engine for later analysis of the driver's performance.
In Step 500, the mapping engine generates a map 22 of the geographic area related to the incident or the area in which the vehicle 16 is traveling. The geographic area covered by the map 22 may also be dependent upon the geographic locations of the various vehicles 16 as reported (as discussed below). The geographic coverage area and/or dimensions may also change over time as the geographic area in which the vehicles 16 are located changes. For example, as a vehicle 16 moves off of the edge of the map 22, the map 22 may automatically adjust (e.g. zoom out or pan) such that all vehicles 16 remain visible on the map 22.
In Step 502, the mapping engine receives location information from the monitoring engine. The location information is indicative of the location in which the vehicle 16 is located. In Step 504, the mapping engine creates an icon 24 on the map 22 at a position associated with the position of the vehicle 16 (i.e. such that the icon 24 on the map 22 approximates the vehicle 16 on the ground). The icon 24 may have a corresponding color, shape, marking, or other indication that is indicative of the vehicle, vehicle type, and/or driver.
In Step 506, the mapping engine refines the location or other attributes of the icon 24 based upon updated information received by the mapping engine from the monitoring engine. For example, as the vehicle 16 moves through the area, the icon 24 is updated to depict an approximate current location. As another example, the icon 24 may begin presenting a first color, such as a green color. If the driver 14 experiences a first incident, the icon 24 may turn a second color, such as yellow, and if the driver 14 experiences a second incident the icon 24 may turn a third color, such as red. This allows the supervisor or dispatcher to quickly determine the quality of driving being exercised by the drivers 14 in the fleet 12 in real time.
In Step 508, the mapping engine receives incident information from the monitoring engine. In Step 510, the mapping engine creates an icon 24 at the geographic location associated with the incident. In some embodiments, the incident information includes location information. In other embodiments, the icon 24 is created at the current geographic location of the vehicle 16 associated with the incident. Typically, the icon 24 will remain static at the associated location, even after the vehicle 16 has moved to another location. This allows the dispatcher or supervisor to identify areas where incidents are common. The mapping engine may additionally or in the alternative generate a map 22 specific to the driver 14 that includes all incidents for a certain time period or specific geographic area.
In Step 512, the mapping engine receives video data from the video repository engine. In Step 514, the mapping engine associates the video data with the icon 24. The mapping engine may update or recreate the icon 24 to indicate that video data is available for this incident. For example, the icon 24 may display a small screen shot of the video on the icon 24 (either by default or on a mouse-over). The mapping may also present an option to the user to request additional video. For example, if the incident video data provided stops while the incident is still in progress, the user may request an additional amount of time of video (such as thirty seconds, one minute, two minutes, etc.). The mapping engine may then request the additional video data from the video repository engine, edit the incident video data to include the additional video data, and present the new video to the user.
The mapping may also display additional incident information to the user that was not immediately available when the icon 24 was created. For example, the vehicle-tracking device 18 may provide minimal incident information over the mobile broadband connection, such as driver involved, vehicle involved, type of incident, and location of incident. Later, upon return to the upload location, the mapping engine may receive more information about the incident, such as vehicle speed during the incident, accelerometer 40 readings during the incident, vehicle systems operating during the incident, and the like. This gives someone reviewing the incident with more information about the cause and fault involved in the incident. The user may also be presented with options to request additional incident information, such as conditions before or after the incident, weather conditions during the incident, the driver's shift hours for that day, etc.
In embodiments of the invention, Step 512 and Step 514 occur after the vehicle 16 has returned to the upload location. This is because transferring video over mobile broadband is typically slow and expensive. In other embodiments, the dispatcher or supervisor can initiate Step 512 and 514 while the vehicle 16 is still driving, as discussed below. For example, if the incident is a vehicular wreck, a shooting involving a law enforcement officer, or another emergency, the video data related to the incident may be vital in alleviating the situation. As a more specific example, if the driver 14 drives off of the roadway and down a ravine and cannot be located by rescue efforts, the dispatcher may select on the map 22 to have the recording device manager 28 or recording device upload the video associated with the incident remotely (because the slowness and expense of mobile broadband are less important in such a situation). As another specific example, if a law enforcement officer is shot and incapacitated by a suspect, the dispatch currently has no way to receive a video of the suspect to assist in his capture. Embodiments of the invention allow the dispatcher to receive the video, via a request made remotely through the mapping engine, and transmit the video (or a screenshot thereof) to the other officers in pursuit of the suspect. In performing these steps, the recording device manager 28 or recording device (which contains the video data) may utilize the communications element 46 of the vehicle-tracking device 18, an internal communications element, a smart phone associated with the driver 14 (via a Bluetooth connection), etc.
In embodiments of the invention, the video data includes orientation information. Orientation information may be derived from a compass element (not illustrated) in the video camera 20, a compass element in the vehicle 16, the direction of travel based on location data, etc. In Step 516, the mapping engine may provide an indication of the orientation of the video data. For example, the indication may be a cone shape in the orientation direction, a shaded area approximating the area covered by the video, etc. In some embodiments of the invention, in Step 518 the mapping engine analyzes the video data to determine a set of video data that covers an inquiry location at an inquiry time based upon the orientation data and a set of location information for the video data. In these embodiments, a user may be attempting to locate video regarding a certain inquiry location, such as the scene of a wreck or crime unrelated to the fleet. The user may enter an inquiry location and inquiry time into the mapping engine. The mapping engine may then analyze vehicles 16 of at least one fleet 12 near that inquiry location at that inquiry time and determine if any were oriented in a direction that may have potentially captured the inquiry time and location. The mapping engine may then present or request any potentially relevant video for review by the user.
As an example of this embodiment, a bank was robbed in the vicinity of a commercial shipping facility. As law enforcement officers are investigating the robbery, they ask the commercial shipping facility supervisor if any commercial shipping vehicles were coming into or out of the facility that may have potentially captured the bank robbers on video. The supervisor enters the location and time of the bank robbery into the mapping engine. The mapping engine analyzes the locations of the vehicles at that time in that vicinity and/or analyzes the location and orientation information associated with all available video data. The mapping engine then identifies one commercial shipping vehicle that had a video camera 20 oriented toward the bank at the inquiry time. The mapping engine then requests the relevant video from the video repository engine and presents the video to the supervisor. As another example, if a vehicle associated with the fleet becomes involved in a collision, the inquiry may determine whether there were any other vehicles in the vicinity that may have captured the collision on video. In some embodiments, the inquiry may search video data from other fleets to which the supervisor (or other user) may not have direct access. If a video is identified, the supervisor may request the video from a supervisor of that fleet.
In Step 600, the video repository engine detects the video camera 20, the recording device manager 28, or the like. The connection may wireless (e.g. Wi-Fi technology, Bluetooth technology, or the like), wired (e.g. via a communications cable), or by the transfer of physical media (e.g. by the removal and manual transfer of a data store). Typically, the connection will be a wireless Wi-Fi connection. For example, as the vehicle returns to the vicinity of the upload location, the recording device manager 28, video camera 20, or recording device establishes a Wi-Fi connection with the video repository engine.
In Step 602, the video repository engine downloads video data from the recording device manager 28, video camera 20, or recording device. In embodiments of the invention, the video repository engine downloads all available video data that was created since the last download process. In other embodiments, the video repository engine may selectively download only certain portions of the video data. In Step 604, the video repository engine stores the video data in an associated data store.
In Step 606, the video repository engine extracts an incident video from the video data based upon the incident information. The incident information may be received from the monitoring engine, from the recording device manager 28, from the vehicle-tracking device 18, be embedded in the video data as metadata, or another source. For example, the video data may have associated metadata indicative of an incident during a certain time period of the video. The video repository engine may then extract that segment of video data, along with a certain period of time before and/or after the incident.
In Step 608, the video repository engine sends the incident video to the mapping engine such that the incident video may be associated with the icon 24. This allows the dispatcher, supervisor, driver 14, etc., to review the video in a convenient manner. The reviewer is not required to find the correct file and skip to the approximate location, as in other systems of the prior art. The user instead simply selects the icon 24 that has the incident video data already associated. Additionally, or in the alternative, the video repository engine may send the incident video to the driver analysis engine for review, analysis, and presentation to a person reviewing the driver's performance.

The user may select the incident icon 62 to display more information about the incident. An exemplary incident details window 58 is illustrated in
In embodiments of the invention, the external camera video player and the internal video camera video player are populated with video data from their respective video cameras automatically. The video repository engine (as discussed above in Step 606) extracts the video data that corresponds with the incident information. The extracted video data is then displayed for review in the incident review interface (and/or on the map). Reviewing the video data along with the incident information provides a better understanding to the reviewer of the conditions and the actions taken by the driver. The video data may provide the reviewer with information as to what caused the incident and allow the reviewer to formulate a plan of action to reduce the severity of or eliminate similar incidents in the future.
In Step 902, the driver analysis engine acquires information related to additional peer fleets 66 (discussed below) beyond the subject fleet 54. In some embodiments, the driver analysis engine stores the information related to all of the fleets 12 in the driver characteristics data store 64. In other embodiments, the driver analysis engine accesses external driver characteristics data stores 64 without transferring data. The information transferred in Step 902 may be redacted, summarized, and/or analyzed (so as to avoid breaches of confidentiality between unaffiliated fleets while still providing analytical benefits).
In Step 904, the driver analysis engine analyzes a subject driver 68 based upon the information received or otherwise acquired. The driver analysis engine receives and analyzes the information that relates to the subject driver 68 and in comparison to other drivers as discussed below. The driver analysis engine organizes and analyzes the data to provide meaningful metrics to the supervisor. The metrics can include incidents per mile, incident severity average, incident cause average, idle time, work time, travel time, analytics of the various metrics, etc.
A simple exemplary depiction of the results of this analysis is illustrated in
Returning to
In Step 906 the driver analysis engine compares the subject driver 68 to peer drivers 74 in the subject fleet 54. The peer drivers 74 are typically operating in the same types of vehicles, in the same geographic areas, and in the same conditions as the subject driver 68. Comparing the subject driver 68 to the peer drivers 74 therefore provides a more useful analysis than considering the subject driver's performance in isolation.
One exemplary depiction of the result of this analysis is shown in the top chart 70 of
Returning again to
In Step 910, the driver analysis engine may compare the subject driver 68 to peer drivers 74 in other peer fleets 66. For example, an ambulance driver may be compared to all ambulance drivers in all peer fleets 66. Some fleets 12 comprise different types of vehicles within the fleet 12. Accordingly, it may not be an accurate comparison to compare the subject driver 68 against all drivers 14 in the fleet 12 because certain drivers 14 in the fleet 12 drive different vehicles 16 under different conditions than the subject driver 68. However, only comparing the subject driver 68 against similar drivers in the same fleet 12 reduces the comparison pool. Therefore, in embodiments of the invention, the driver analysis engine compares the subject driver 68 to comparable drivers 14 in both the subject fleet 54 and in peer fleets 66. For example, a squadron of military aircraft may have a single refueling aircraft along with multiple fighter aircraft. It would be of little value to compare the subject driver 68 (i.e. the pilot) of the refueling aircraft against the fighter aircraft pilots. A more valuable comparison would be to compare the pilot of the refueling aircraft against the pilots of other refueling aircraft in other squadrons. Similarly, in the law enforcement field, comparing the driving habits of a detective against patrol officers would not be as advantageous as comparing the detective to other detectives in the same precinct and in other precincts.
In Step 912, the driver analysis engine compares the subject driver 68 against all peer drivers 74 in the same geographic area. For example, if the subject driver 68 primarily drives on a certain route, the driver analysis engine may compare the subject driver 68 against all other drivers 14 (regardless of fleet) on that certain route. For example, if many drivers 14 register an incident rounding a certain turn on the route, the subject driver 68 may be less-severely penalized for incidents along the route because registering of the incident may be anomalous.
In Step 914, the driver analysis engine produces a driver score, a driver report, or other grade. The driver score may be detailed, in that it includes a sub-score for many different areas. The driver score may also be a single value that is calculated based upon the sub-scores. In some embodiments, the driver analysis engine may weight various sub-scores based upon their importance, their departure from the averages, etc. For example, if the subject driver 68 performs well in all areas except having numerous excessive accelerations, the driver analysis engine may weight the excessive accelerations as more important when calculating the driver score.
In Step 916, the driver analysis engine determines, recommends, and/or creates driver training to address identified deficiencies. The driver training can be in numerous forms including multi-media, education, driving simulation, and the like.
In some embodiments, the driver analysis engine may compare an entire fleet 12 of drivers 14 against another entire peer fleet 66. As depicted in
