Determining street segment headings

A computing system comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the processor, cause the computing system to at least:

• receive a plurality of instances of vehicle telematics data indicative of a travel path of a vehicle on a street segment during one or more time periods, wherein each instance of the vehicle telematics data (a) comprises location data captured by a location-determining device onboard the vehicle and (b) is captured responsive to a triggering event, the plurality of instances of vehicle telematics data comprising (i) a first instance of telematics data wherein the triggering event is detection of a vehicle event based on data generated by one or more vehicle sensors of a plurality of vehicle sensors onboard the vehicle, and (ii) a second instance of telematics data wherein the triggering event is a determination that a threshold amount of time has elapsed since the preceding instance of the vehicle telematics data was captured;
• segment the vehicle telematics data to determine the portion of the vehicle telematics data corresponding to the travel path of the vehicle on the street, wherein to segment the vehicle telematics data, the at least one memory and the computer program code are configured to, with the processor, cause the computing system to at least:
• access a street segment definition associated with the street segment,
• identify a plurality of data points along the street segment, wherein identifying the plurality of data points comprises identifying (a) a segment starting point where the vehicle entered the street segment, where the segment starting point is a data point where an immediately preceding data point was not captured when the vehicle was located on the street segment and (b) a segment ending point where the vehicle exited the street segment, where the segment ending point is a data point where an immediately seceding data point was not captured when the vehicle was located on the street segment,
• assess the location data of the vehicle telematics data based on the street segment definition,
• identify one or more instances of vehicle telematics data corresponding to the street segment definition, and
• define a set of instances of vehicle telematics data consisting of the identified one or more instances of vehicle telematics data corresponding to the street segment definition,
• based at least in part on the set of instances of vehicle telematics data, determine a street segment direction for the street segment, the determined street segment direction indicating whether the street segment is a one-way street segment or a bidirectional street segment;
• identify map data associated with the street segment, wherein the map data
• comprises street segment direction data indicator indicating whether the street segment is a one-way street segment or a bidirectional street segment;
• and
• update the map data to reflect the determined street segment direction for the street segment direction.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• an executable portion configured to receive a plurality of instances of vehicle telematics data indicative of a travel path of a vehicle on a street segment during one or more time periods, wherein each instance of the vehicle telematics data (a) comprises location data captured by a location-determining device onboard the vehicle and (b) is captured responsive to a triggering event, the plurality of instances of vehicle telematics data comprising (i) a first instance of telematics data wherein the triggering event is detection of a vehicle event based on data generated by one or more vehicle sensors of a plurality of vehicle sensors onboard the vehicle, and (ii) a second instance of telematics data wherein the triggering event is a determination that a threshold amount of time has elapsed since the preceding instance of the vehicle telematics data was captured;
• an executable portion configured to segment the vehicle telematics data to determine the portion of the vehicle telematics data corresponding to the travel path of the vehicle on the street, wherein, to segment the vehicle telematics data, the executable portion is configured to:
• access a street segment definition associated with the street segment, assess the location data of the vehicle telematics data based on the street segment definition,
• identify a plurality of data points along the street segment, wherein identifying the plurality of data points comprises identifying a segment starting point where the vehicle entered the street segment, where the segment starting point is a data point where an immediately preceding data point was not captured when the vehicle was located on the street segment,
• identify one or more instances of vehicle telematics data corresponding to the street segment definition, and
• define a set of instances of vehicle telematics data consisting of the identified one or more instances of vehicle telematics data corresponding to the street segment definition,
• an executable portion configured to, based at least in part on the set of instances of vehicle telematics data, determine a street segment direction for the street segment, the determined street segment direction indicating whether the street segment is a one-way street segment or a bidirectional street segment;
• an executable portion configured to identify map data associated with the street segment, wherein the map data comprises street segment direction data indicator indicating whether the street segment is a one-way street segment or a bidirectional street segment;
• and
• an executable portion configured to update the map data to reflect the determined street segment direction for the street segment direction.
