This paper provides an evaluation of how communication performance between vehicles of Dedicated Short-range Communication (DSRC) devices varies among different driving scenarios. DSRC is a wireless technology developed especially for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications. DSRC communication involves vehicles moving on the same roadway, both same-direction traffic and opposite-direction traffic. A frequency band near 5.9 GHz has been set aside in the US and other countries for exploring safety and other uses for road vehicles. DSRC devices onboard vehicles broadcast their location using global navigation space systems (GNSS), speed, heading, and other information. This can be used to study communication performance in many scenarios including: car-following situations, rear-end crash avoidance, oncoming traffic situations, left turn advisory, head-on crash avoidance and do-not-pass warnings. The V2V performance measures of packet capture rate and intra-packet loss are presented to highlight how these measures change with the distance and orientation of the vehicles and how DSRC antenna location (package shelf or roof) impacts communication performance. The data used in this study include two datasets, safety pilot model deployment and data collected from one on-road experiment, during which communication performance was evaluated under two DSRC antenna locations. Results of different performance was observed and further discussed.
