Research and Simulation on Cooperative Adaptive Cruise Control Vehicles Based on PTV VISSIM

With the continuous development and maturity of the application of computer and wireless communication in the field of transportation, the development of autonomous vehicles has also made remarkable achievements. The present research mainly focuses on how a single vehicle operates autonomously without a driver, but less research on the traffic flow consisting of autonomous vehicles has been done. This paper aims to simulate cooperative adaptive cruise control (CACC) vehicles, which is the significant phase to completely self-driving, setting new rules for car-following, and lane-changing vehicles by modifying the external driver behavior model of PTV VISSIM. By comparing the differences between conventional traffic flow and CACC flow, some conclusions are drawn to support further research. This paper concludes with three new findings on the characteristics of CACC flow for further research.
