Design of Urban Traffic Node Management Scheme Based on 5G Wireless Network Architecture

Effective management of urban traffic nodes can improve the order and efficiency of road traffic, and play a pivotal role in alleviating urban traffic congestion. To this end, a city traffic node management scheme based on 5G wireless network architecture is designed. This method first collects relevant traffic characteristic data, and then uses 5G cellular mobile communication technology to establish the connection between the control center and the on-board unit and roadside unit to realize real-time vehicle and road data transmission. Finally, it uses the algorithm based on dynamic programming to perform urban traffic node signal lights. Control and realize urban traffic flow scheduling. The results show that: under the application of the designed scheme, the number of vehicles in the queue is reduced, and the average delay time of vehicles is reduced, thus effectively improving the utilization efficiency of road traffic resources and alleviating the problem of urban traffic congestion.
