Modeling the Effectiveness of Crash Avoidance Systems that Support Driver Maneuver Decisions: Lane Change Crash Avoidance Example and Issues

The purpose of this paper is to present a Crash Avoidance Systems (CAS) effectiveness modeling framework, based on concepts from reliability theory, that may complement kinematic, dynamic, and epidemiological methods for estimating CAS effectiveness. A sensitivity analysis is then reported that determined the impact of various model parameters and assumptions on effectiveness as the parameters vary. The paper concludes with a discussion of limitations and data needs associated with this modeling approach.

Analytical Evaluation of Warning Onset Rules for Lane Change Crash Avoidance Systems

This study assessed the potential effectiveness of two warning onset rules for lane change Crash Avoidance Systems (CAS). A minimum-separation rule triggers a driver warning whenever the Subject Vehicle (SV) and Principal Other Vehicle (POV) are within some minimum lateral separation distance. A turn-signal onset rule triggers a driver warning when the driver activates the turn signal indicator and there is a vehicle in the blind spot. A software program to simulate lane change crashes determined the maximum time available for driver surprise reaction time to the warning and estimated the proportion of crashes avoided with each warning rule. Results indicate that the minimum separation rule is unlikely to be effective for lane change crash avoidance but may help prevent lane-drift-related crashes. The turn-signal onset rule will likely be effective for drivers who use their turn signals but is not free of nuisance alarm problems. Recommendations for lane change CAS research and development are provided.
