1. A vehicle, comprising:
a data interface that receives traffic object data from sensors including one or more of a camera, a Global Positioning System, Lidar and radar resident in the vehicle;
a processor in the vehicle connected to the data interface; and
a memory in the vehicle connected to the processor, the memory storing instructions executed by the processor to:
process the traffic object data to form geometric and kinematic data; and
process the geometric and kinematic data to form a hazard measure, where the hazard measure is computed through operations to:
obtain a relative speed between a first traffic object and a second traffic object,
receive a separation distance between the first traffic object and the second traffic object,
combine the relative speed and the separation distance to form a quantitative measure of hazard encountered by the first traffic object, wherein the instructions to combine include instructions to:
apply a compensating factor to the relative speed to form a compensated relative speed, and
divide the compensated relative speed by the separation distance,
repeat the obtain, receive and combine operations to form cumulative measures of hazard associated with the first traffic object,
analyze the cumulative measures of hazard to derive a first traffic object safety score for the first traffic object; and
adjust or affect the behavior of the vehicle in response to the first traffic object safety score.
