Vehicle turn detection
A turn detection system is configured to determine headings or a course of a vehicle over a period of time and evaluate whether the vehicle has registered a turn based on these headings/course. In some arrangements, upon detecting a turn, sensor data may be collected to determine one or more characteristics or attributes of the turn. Such data may indicate a loss event associated with the turn and be used to calculate a probability or risk of loss given the various characteristics of the turn. These probabilities may further be applied to determine various costs and premiums.
1. A movement event detection apparatus comprising: a communication interface;
a processor; and
memory storing computer-readable instructions that, when executed by the processor, cause the movement event detection apparatus to:
receive, from a remote device, position information for a vehicle through the communication interface, the remote device being exterior to the vehicle;
determine headings of the vehicle based on the position information;
collect a plurality of turn events associated with the vehicle based on the determined headings;
filter the turn events down to those that are associated with a respective loss event, wherein the respective loss event occurred within a turning period that includes respective turn events or within a predefined amount of time of the respective turn events, and wherein the respective loss event is detected using sensor data collected from a respective vehicle;
select a set of one or more attributes to compare against the filtered turn events associated with the respective loss event;
determine a range of values of each respective attribute exhibiting at least a threshold percentage of loss events; and
calculate an overall risk associated with the vehicle based on the determined ranges of values.

determine headings of the vehicle based on the position information;
collect a plurality of turn events associated with the vehicle based on the determined headings;
filter the turn events down to those that are associated with a respective loss event, wherein the respective loss event occurred within a turning period that includes respective turn events or within a predefined amount of time of the respective turn events, and wherein the respective loss event is detected using sensor data collected from a respective vehicle;
select a set of one or more attributes to compare against the filtered set of turns associated with the respective loss event;
determine range of values of each respective attribute exhibiting at least a threshold percentage of loss events; and
calculate an overall risk associated with the vehicle based on the determined ranges of values.
