The invention discloses an intelligent traffic signal control method based on open-source road condition information, and solves the problem that the intelligent degree of traffic signal control stillneeds to be improved in the prior art. The method comprises the following steps: step 1, collecting traffic data under an open-source real-time road condition; 2, evaluating a congestion index; 3, constructing an intelligent signal period model; and step 4, constructing an intersection signal lamp timing model based on the open-source real-time road condition traffic data. The technology is mainly used for coping with traffic congestion in peak hours; experimental results are consistent with expectations; the heavier the traffic is, the better the relieving effect of the method is; the congestion queuing is reduced by 16.14% under a general congestion condition, while the congestion queuing is reduced by 29.99% under a severe congestion condition, so that the traffic capacity of the roadis obviously improved; and on one hand, the urban road construction cost can be saved, and on the other hand, the vehicle travel cost can be reduced.
本发明公开了一种基于开源路况信息的智能交通信号控制方法,克服了现有技术中,交通信号控制的智能程度仍待改进的问题。该发明含有以下步骤:步骤1,采集开源实时路况下的交通数据;步骤2,评价拥塞指数;步骤3,构建智能信号周期模型;步骤4,基于开源实时路况交通数据的路口信号灯配时模型。该技术主要用来应对高峰时段的交通拥塞,实验结果与预期一致,交通愈拥塞,本方法缓解效果愈好,在一般拥塞情况下减少拥塞排队16.14%,在严重拥塞情况下减少拥塞排队29.99%,显著提升了道路的通行能力,一方面可以节约城市道路建设成本,另一方面可以降低车辆出行成本。
