最近，基于无线传感器网络(WSNs)和开放最短路径优先(OSPF)协议，作者提出了一种分布式动态路径诱导系统UTOSPF(Urban Traffic Open Shortest Path First)。在UTOSPF中，只会根据估计的街道旅行时间(ESTT)来找到路线，而不考虑司机在红灯后花费的等待绿灯时间(WTGL)。本文提出了一种将WTGLS引入最优路径计算的简单方法，并给出了仿真结果。仿真结果表明，在仿真场景中，与随机路径相比，该方法可以将车辆的平均速度提高66%，与原始UTOSPF相比，平均速度可以提高27%。
Recently, the authors proposed a distributed dynamic route guidance system called UTOSPF (Urban Traffic Open Shortest Path First) based on Wireless Sensor Networks (WSNs) and Open Shortest Path First (OSPF) protocol. In UTOSPF, the routes will be found only based on Estimated Street Travel Times (ESTTs) which will be needed to pass the streets and regardless of Waiting Times for Green Light (WTGLs) which drivers spend behind the red lights. In this paper, a simple method will be proposed to involve the WTGLs in calculation of optimal routes and its simulation results will be presented. Simulation results show that this method can improve the average speed of vehicles up to 66% as compared to random routes and up to 27% as compared to original UTOSPF, in the simulated scenarios.
