The invention discloses an intelligent network connection mixed traffic flow intersection signal collaborative optimization method and system. The method comprises the following steps: carrying out high-precision acquisition on traffic state information; optimizing the trajectory of the intelligent vehicle based on initial information control; and performing optimization based on the optimized signal control of the intelligent vehicle track. In this way, the defects that in a mixed traffic mode, the permeability of the intelligent vehicles is low, a large number of intelligent vehicles follow the manual driving vehicles, only single intelligent vehicles are controlled, the multi-vehicle following state is not considered, and the optimization effect is limited are overcome. Meanwhile, by adopting a track and signal collaborative optimization mode, the operation efficiency of the intersection is further improved, it is guaranteed that a data source is more accurate and microcosmic, and a control strategy is more reasonable and effective.

    本发明公开一种智能网联混合交通流交叉口信号协同优化方法及系统,该方法包括对交通状态信息进行高精度采集;基于初始信息控制的智能车轨迹进行优化;基于优化后的所述智能车轨迹的信号控制进行优化。这样,避免了混合交通模式下,智能车渗透率较低,存在大量的智能车跟驰人工驾驶车辆及仅仅控制智能车单车,未考虑多车跟驰状态,优化作用将有限的缺点。同时,通过采用了轨迹与信号协同优化的方式,进一步提升交叉口的运行效率,保障了数据来源更精确、微观,并且控制策略更合理、有效。
