Abstract :
We study the effect of vehicle vehicle/vehicle-roadside communication on the performance of adaptive cruise control (ACC) systems. Two simulation works are presented One is a single ACC vehicle simulation using MATLAB/SIMULINK. A cut-in scenario and a braking scenario are tested Communication greatly saves control effort in the former scenario, while has little effect in the latter. The other work simulates ACC controlled highway merging with SHIFT language. The results show beneficial effects of communication in terms of braking effort, waiting-to-merge queue length, and main lane traffic shock wave caused by merging.
