The invention discloses a signal control scheme recommendation method and system for a saturated urban traffic network, and relates to the technical field of intelligent traffic. The signal control scheme recommendation method comprises the following steps of: recognizing a congested intersection in real time; inputting real-time traffic data of the congested intersection into a signal control scheme evaluation model for calculation to obtain a current score of each signal control scheme, wherein the signal control scheme evaluation model is obtained by training according to historical trafficdata of a plurality of similar intersections with traffic attribute features similar to those of the congested intersections and real historical scores of signal control schemes used in history; sorting the signal control schemes according to the current scores, and selecting a plurality of credit control schemes with top scores to obtain a credit control scheme recommendation list; and pushing the signal control scheme recommendation list to a regulation and control signal terminal. The signal control scheme recommendation method is suitable for the saturated urban traffic networks with a large number of congested intersections, and is efficient, accurate and high in adaptability.
本发明公开了一种用于饱和城市交通网络的信控方案推荐方法及系统,涉及智慧交通技术领域,该方法包括以下步骤:实时识别拥堵交叉路口;将拥堵交叉路口的实时交通数据输入信控方案评价模型进行计算得到各信控方案的当前评分,其中,信控方案评价模型根据与拥堵交叉路口的交通属性特征相似的若干个相似交叉路口的历史交通数据以及历史使用各信控方案的真实历史评分训练得到;将各信控方案按照当前评分大小进行排序,选取评分排名靠前的若干个信控方案得到信控方案推荐列表;将信控方案推荐列表推送至调控信号终端。该方法适用于具有大量拥堵交叉路口状态下的饱和城市交通网络,高效准确,适应性强。
