| Abstract: | This report describes the findings and recommendations from the heavy-truck (HT) extended pilot test (EPT) conducted by University of Michigan Transportation Research Institute (UMTRI) and its partners under the Integrated Vehicle-Based Safety Systems (IVBSS) program. The EPT was conducted to provide evidence of system performance (alert rate and reliable operation) and driver acceptance prior to conduct of the field operational test (FOT). The results of this test were to be used to modify the HT system performance and functionality as required, prior to the start of the FOT. The EPT entailed use of an integrated crash warning system in a heavy truck by seven drivers, over a period of five days each, in the course of their regular duties as drivers for Con-way Freight at the Ann Arbor distribution center. The test lasted four weeks starting on November 10 and ending December 12, 2008; the resultant data represent 5,300 miles of system use. The extended pilot test of the heavy truck platform on the IVBSS program successfully evaluated system performance and driver acceptance. Driver recruitment and training procedures were tested, as were the driver survey and debriefing methodologies. The warning system and data acquisition hardware operated reliably through the EPT. However, the warning system had an alert rate that was higher than anticipated based on previous testing. Nonetheless, drivers were generally still accepting of the system. Valuable data obtained from the EPT have led to further system performance improvements in the detection of stopped and slower-moving objects by the FCW subsystem in order to reduce the alert rate, and these enhancements have been implemented into the heavy truck fleet for the full field operational test. |
