The effect of traffic barriers on radio wave propagation

Aiming at the needs of more accurate and efficient radio propagation models for complex urban environments, the wireless channel transmission power and traffic flow information in this environment are measured based on the existing electromagnetic test system and traffic flow information acquisition equipment for classic urban street environments. The measured results show that when the transceiver antenna is low and there are traffic barriers between the transceiver and receivers, the signal propagation loss is positively correlated with the traffic flow obstacles, and the signals of different frequencies are affected by the traffic flow obstacles.
