Based on the foundation of the frontal and side collision warning systems, the Frontal Collision Warning System (FCWS) and Side Collision Warning System (SCWS) teams joined efforts to improve the collision warning algorithms. The objective of the ICWS Program is to study how frontal and side collision warning system might interface with each other, and to develop prototype ICWS systems on two buses, one at Samtrans and the other at PAT. The prototype ICWS buses have been in revenue operation in the Bay Area and Pittsburgh to collect field operational data and driver responses. The results of the ICWS design, build, and integration efforts as well as an analysis of early data collections to evolve the warning algorithms are documented in this final technical report. Evaluation and performance analysis are currently being finalized and will be issued in a separate report.

    This evaluation report examines the performance of the Integrated Collision Warning System prototype developed by the University of California PATH Program and the Carnegie Mellon University Robotics Institute. The evaluation was based on testing the sensors, processing algorithms, and driver-vehicle interfaces in both controlled and real world operational environments. Evaluation metrics and methodologies were used to evaluate the effectiveness of the system. The effort for this evaluation was based on the following tasks:

    Task 1: Develop Evaluation Scenarios

    Task 2. Perform Closed Course System Testing Under Controlled-Environment

    Task 3. Conduct Detection Analysis

    Task 4 Analyze Driving Behavior Data

    Task 5 Surveys and Interviews
