Characterization Test Procedures for Intersection Collision Avoidance Systems Based on Vehicle-to-Vehicle Communications

Overview

Characterization test procedures have been developed to quantify the performance of intersection collision avoidance (ICA) systems based on vehicle-to-vehicle communications. These systems warn the driver of an imminent crossing-path collision at a road junction, and apply automatic braking if the driver does not respond in a timely manner to prevent the collision. This report describes test procedures for most common crossing-path pre-crash scenarios that involve light vehicles (passenger cars, vans, minivans, SUVs, or light pickup trucks with gross vehicle weight ratings less than 10,000 pounds). The test procedures include crash-imminent test scenarios to collect information on the ranges and time-to-collisions of crossing-path collision alerts and automatic braking onsets in prototype systems. In addition, the test procedures incorporate dynamic scenarios where countermeasure action is not needed so as to assess the capability of ICA systems to distinguish between crash-imminent and benign driving scenarios.
