1. A system for assessing turns made by at least one vehicle, said system comprising:

  • one or more memory storage areas; and

    one or more processors in communication with said one or more memory storage areas;

    wherein said processors are, collectively, configured to;

    receive, from one or more vehicle telematics devices located on the at least one vehicle, vehicle telematics data indicative of a travel path of the vehicle during one or more time periods, wherein the vehicle telematics data comprises a plurality of telematics data points, each telematics data point comprising data indicative of a vehicle heading at a particular location along the travel path of the vehicle and a time the data point is generated;

    identify, based at least in part on said vehicle telematics data, one or more turns executed by the vehicle during the one or more time periods, the one or more turns each comprising instances in which the vehicle executes a turn in order to change from (i) traveling in a first roadway direction on a first road to (ii) traveling on a second road or traveling in a second roadway direction on the first road, wherein the one or more turns are each identified as comprising a change in vehicle heading between successive telematics data points of the plurality of telematics data points exceeding a predefined threshold heading value;

    determine for each identified turn a turn segment comprising;

    a beginning turn point comprising a telematics data point occurring before the successive telematics data points;

    an ending turn point comprising a telematics data point occurring after the successive telematics data points;

    the time elapsed between the beginning turn point and ending turn point, wherein the time elapsed defines the duration of the turn segment; and

    an intersection type where the identified turn segment occurs by;

    identifying, based at least in part on a telematics data point corresponding to the identified turn segment, a location of the turn segment;

    comparing the location of the turn segment against map data to identify one or more roads intersecting at the location of the turn segment; and

    determining, based at least in part on the one or more roads intersecting at the location of the turn segment, an intersection type for the turn segment;

    receive a user request for analysis of turns corresponding to one or more identified intersection types;

    identify, based at least in part on telematics data corresponding to each turn segment, those turn segments occurring at one of the identified intersection types; and

    generate, based on said identified turn segments, a graphical display comprising a map illustrating the location of the identified turn segments and displaying one or more turn segment attributes of said identified turn segments.
