Title: Effects of Cooperative Adaptive Cruise Control on Traffic Flow: Testing Drivers' Choices of Following Distances
Abstract: This report describes the design and implementation of a Cooperative Adaptive Cruise Control (CACC) system on two Infiniti FX-45 test vehicles. The system was developed through the addition of a wireless vehicle to vehicle communication system and new control logic to a pre-existing commercially available adaptive cruise control (ACC) system. The CACC is designed to enhance the vehicle-following capabilities of ACC, allowing drivers to be comfortable in using it at vehicle-following gaps that are shorter than ACC. The report also describes the data acquisition system which was installed for measuring how drivers use the system. The intent here is to be able to estimate the impacts of such a system on highway traffic flow capacity and stability. The report presents the results of quantitative performance testing of the CACC on a test track. It also presents the experimental protocol to be followed for on-road testing with human subjects. Finally, the results from the first pilot test are presented, indicating how the data is analyzed and thus revealing the implications of CACC for driving behavior and user acceptance
