Abstract: With the rapid development of the national economy, traffic demand is increasing, traffic congestion, traffic violations and other phenomena occur frequently, which has become a common problem faced by various cities. Intelligent Transportation System (ITS) is an effective way to solve road traffic problems. Aiming at the optimization of urban road traffic information acquisition system, a constrained optimization mathematical model of intelligent traffic information acquisition system with conference network is established by using the comprehensive evaluation function of connectivity and coverage of radio frequency identification (RFID) technology. Connection and coverage are constraints. The penalty function method is used to further transform the model into an unconstrained optimization model. Taking the road in the Second Ring Road of Beijing as an example, the simulation experiment is carried out by using radio frequency identification technology. The results show that compared with the initial manual layout, the evaluation function value of the optimized layout can be increased by 1.71% and 3.18% by RFID technology. Radio Frequency Identification (RFID) technology can optimize the traffic information acquisition system.
