The invention provides an intersection variable lane control method based on short-time traffic state prediction. The intersection variable lane control method comprises the steps of obtaining an intersection adjacent relation through an electronic map; according to historical statistical data, obtaining an afflux ratio of each intersection in each monitoring time period; counting the current traffic flow of each intersection; taking a single intersection as a monitored object, and obtaining the to-be-imported traffic flow of the monitored object according to the current traffic flow and the import ratio of the adjacent intersections of the monitored object; obtaining the retention amount of the monitored object in the current control period according to the current signal lamp phase and the afflux ratio of the monitored object; evaluating the blockage risk of the monitored object according to the retention amount and the to-be-imported traffic flow, and for the monitored object with the blockage risk, adjusting the phase of signal lamps according to the current traffic flow and the import ratio in each circulation direction. According to the invention, the lowest blockage risk atintersections is realized, and smooth traffic is ensured.

    本发明提出的一种基于短时交通状态预测的交叉口可变车道控制方法包括:通过电子地图获得交叉口相邻关系;根据历史统计数据,获得各监控时间段上各交叉口处的汇入比;统计各交叉口当前车流量;以单个交叉口为监控对象,根据监控对象的相邻交叉口的当前车流量和汇入比,获得监控对象的待汇入车流量;根据监控对象当前的信号灯相位以及汇入比,获得监控对象当前控制周期内的滞留量;根据滞留量和待汇入车流量评估监控对象的堵塞风险,对于存在堵塞风险的监控对象,则根据当前车流量和各流转方向上的汇入比调整信号灯相位。本发明,实现了交叉口处最低堵塞风险,有利于保证交通通畅。
