An experimental investigation into the impact of vehicular traffic on V2V communication channel

Vehicle to vehicle (V2V) communication plays a key role in the safety of autonomous vehicles. Therefore, practical tests in many environments are essential. This study presents measurements of signal strength and Doppler of a 5.9 GHz V2V channel at a road junction in Leicester city centre. The signal shows variations which depend on the size, speed and location of vehicles relative to the line of sight between the stationary transmitter and receiver. Disturbances in the received signal from different types of vehicles have been studied as they pass through the V2V channel resulting from transmitter and receiver positioning opposite sides of the road. The results showed that the size of the vehicle is an important factor when looking at the impact on a V2V link.
