Research on Road Network Optimization of Traffic Congestion Reduction based on Vehicle as Sink Node

As the number of motor vehicles in developing countries increases year by year, the increase in the number of vehicles has brought a series of problems to urban traffic, such as traffic congestion and road safety issues. The road traffic information is effectively transmitted to the on-board self-organizing network. The on-board self-organizing network can communicate with people, vehicles, vehicles and vehicles, and vehicles and roadside facilities to optimize the road network reasonably and reduce traffic The purpose of congestion. Starting from the road traffic network, this paper mainly studies a routing protocol for road information acquisition with roadside unit vehicles as SINK nodes. Based on this information, a road network optimization for the global road network is proposed. algorithm. From a global perspective, reduce road congestion and improve road utilization.
