Simulating Rear-End Collision Warnings Using Field Operational Test Data 2001-01-0461

This paper discusses the definition and performance of the warning algorithm in a potential Rear-End Collision Avoidance System (RECAS). Given vehicle range, velocity, and leader deceleration data, the warning algorithm computes whether imminent braking is required to prevent a collision with a vehicle directly ahead, and determines whether a warning should be given to alert the driver. The result of the study is an estimate of the number of warnings per hour under normal driving conditions for various types of drivers.
