Design and application of urban traffic state evaluation system

摘要

Urban road congestion is increasingly serious, in order to optimize the traffic situation, and improve the efficiency of vehicles, so as to provide service for traveling user. Then analysis four major systems, namely the bus electronic station board system, evaluation system of urban road traffic state, urban traffic guidance system and website demonstration system. Regarding average travel speed, congestion coefficient and mean velocity gradient as evaluation index of evaluation system, to simulate the bus electronic station board to obtain corresponding real-time traffic flow data. A website design platform is used for dynamic demonstration of urban road traffic state, and the evaluation result is determined. Finally, the valid data will be released to the scene of traffic for reasonable traffic grooming.
