Veridian, Calspan Operations is currently developing an on-vehicle threat detection system for intersection collision avoidance (ICA) as part of its ICA program with the National Highway Traffic Safety Administration. This paper briefly reviews the system design and describes recent efforts that include the development of a multi-radar collision avoidance (C/A) system. Results from in-traffic experiments utilizing two radars to simultaneously observe crossroads traffic from both directions will be presented for the first time. Warning functions were applied to the data in real time and for non-real-time signal processing. These functions warn the ICA vehicle against entering the intersection when targets are predicted to be present. This research demonstrates the feasibility of preventing many intersection collisions.

Calspan SRL Corporation is currently developing an on-vehicle threat detection system for intersection collision avoidance (ICA) as part of its ICA program with the National Highway Transportation Safety Administration. This paper briefly reviews the system design and describes recent efforts that include the development of a simulation of a multitarget tracker and collision avoidance (C/A) algorithm used to predict system performance in a variety of target configurations in various ICA crash scenarios. In addition, a current headway radar was mounted on the Calspan Instrumented Vehicle (CIV) and in-traffic data were recorded for two limited crash scenarios. Warning functions were developed through the simulation and applied to the recorded data (non-real-time signal processing). This research demonstrates the feasability of preventing many intersection collisions.
