Abstract

本发明涉及数据分析技术领域，尤其涉及一种复杂市政立交桥区域智慧交通信号优化调度方法，通过确定高峰拥堵时段，分析静态影响数据以及历史交通数据，计算所述高峰拥堵时段的拥堵风险表征值，以确定各监测子区域的拥堵风险倾向；响应于高拥堵风险倾向，获取所述监测子区域的实时交通运行图像，分析车流交织点以及匝道合流点确定道路冲突系数，结合所述拥堵风险表征值计算道路拥堵指数，确定道路拥堵路段，计算行驶耗费指数以及调整耗费指数，确定是否需要调整行驶路径，并确定信号配时方案，进行信号优化调度。本发明通过对立交桥进行区域性拥堵状态分析，对比各子区域的拥堵状态以及耗费指数，确定信号配时方案，保证立交桥的道路快速通行。
