Effects of Traffic Density on Communication Requirements for Cooperative Intersection Collision Avoidance Systems (CICAS)

Cooperative Intersection Collision Avoidance Systems (CICAS) are likely to be among the first and most quality-of-service-critical users of wireless DSRC communications. Vehicle and infrastructure systems need to exchange data about the state of the intersection with high reliability and low latency. This paper estimates the number of vehicles that would need to share the DSRC safety communication channel at an intersection under worst-case conditions in rural, suburban and urban environments, to provide a starting point for defining the capacity that wireless channel needs to provide in order to support CICAS services.
