Investigating Communications Performance for Automated Vehicle-based Intersection Control under Connected Vehicle Environment

This paper investigates the wireless communications performance of Cooperative Vehicle Intersection Control (CVIC) powered by the Connected Vehicle (CV) environment. Considering the CV communication standards defined in IEEE 802.11p, IEEE 1609, and SAE J2735, the performances of CV communications were examined under several external factors including the number of On-Board Units (OBUs) and the distance between transceivers by using an off-line simulation framework integrating NCTUns, a wireless communications network simulator, for DSRC communications and VISSIM for vehicular movements. Unlike perfect communications assumptions made in most CV studies in the transportation literature, a case study implementing the simulations of the CVIC algorithm showed that no perfect packet deliveries were observed, resulting in about 48% packet drops at most.
