Vehicle-to-Everything (V2X) communication, specifically Dedicated Short-Range Communication (DSRC), was developed for wireless communication and information sharing between vehicles and their surrounding environment in an effort to create a safer road ecosystem. With connected vehicle technology becoming more prevalent in today's market, this paper intends to empirically define the external factors that influence the radiation pattern of a commercially available DSRC-equipped vehicle. As DSRC can be influenced by different road and environmental conditions, the aim was to investigate the potential sources that cause a reduction in communication efficiency by looking at their effect on signal strength and packet loss. 728 test runs were performed and their results used to evaluate the DSRC communication under 12 environmental and obstruction conditions. Results indicate that environmental conditions, such as temperature, water particles and type of road surface covering have minimal impact on V ehicle-to- Vehicle (V2V) communication. In contrast, physical obstructions, whether from the surrounding environment or on the vehicle's antenna, cause larger variations in the signal strength and in the packet loss. These results may be used to inform the public, industry and regulators on DSRC limitations, while similar test methods can be used to evaluate other forms of connected vehicles technology, such as Cellular Vehicle-to-Everything (C-V2X).
