高速公路交通智能化控制研究

Research on Intelligent Control of Highway Traffic

不利条件下高速公路交通流的智能化控制对交通运行的安全具有重要意义.通过建立不利状况下高速公路的智能控制模型,分析了高速公路中非匝道瓶颈路段、匝道瓶颈路段、非瓶颈路段的自身影响因子以及对其他路段产生的影响,得到了各个路段的车辆控制密度.并结合车辆控制密度与路段车辆实际密度的关系,制定车速控制方案,最终将限速信息及时发布,以达到对高速公路交通流的智能化控制的目的.

Intelligent control of highway traffic flow is of important significance for traffic safety under unfavorable conditions. By setting up the intelligent control model of highway under unfavorable conditions,the impact factors of non- ramp bottleneck,ramp bottleneck,and non- bottleneck road section,and the impact on other road sections are analyzed. The vehicle control density of each road section is obtained. Combined with the relation of vehicle control density and actual density,we could make speed control scheme,and timely release speed limit information in final,so as to realize the intelligent control of traffic flow in highway.
