道路交通流最优预测与交叉口最优控制

The Optimal Prediction of Road Traffic Flow and Optimal Control of Intersection Signal

本文基于对城市道路交叉口最优控制问题的分析,建立了道路交通流最优预测模型,提出了一种交叉口在线最优控制方法,并根据实测数据对该方法作了仿真研究。仿真结果表明交叉口的交通状况有明显改善。此方法不仅比现有控制方法效果更好,而且简单易行。

Based on the analysis of the intersection signal optimal control problem, an optimal prediction mo-del of road traffic flow is established and an on-line optimal signal control method is proposed in this paper. The simulation results according to practical data show that the situation of intersection traffic can be improved greatly. The method is not only more effective than current methods but also simpler and easier to be realized.
