高速公路隧道交通流量预警算法研究
Study on Early Warning Algorithm of Freeway Tunnel Traffic
摘要
Abstract
According to the characteristic of freeway tunnel traffic ,the importance of the tunnel section con-gestion warning was discussed ,the relation between tunnel internal relations and actual change processes was analyzed ,the warning tunnel congestion algorithm based on the tunnel entrance traffic flow was proposed .By the smart card port on the inlet and outlet of the tunnel traffic statistics ,an algorithm of tunnel traffic was de-rived .The Algorithm implement real-time monitoring of tunnel congestion by shifting constant ,by observing the congestion index we can know the tunnel road traffic conditions .In the freeway for testing and analysing of the algorithm ,the experimental data show that ,the presented method of freeway congestion warning is ef-fective .The algorithm is applied to freeway traffic management will effectively improve the traffic safety level of freeway especially the tunnel area .关键词
