The invention relates to a left-turn main pre-signal linkage control method and device, and a storage medium. The method comprises the steps: determining a main intersection flow multiplier, a sub-intersection flow multiplier and a weighted average bandwidth according to a plurality of road parameters; performing weighting processing on the main intersection flow multiplier, the sub-intersection flow multiplier and the weighted average bandwidth, and determining a target planning model; establishing at least one lane constraint condition according to the plurality of road parameters; and determining a globally optimal solution of the target planning model according to the at least one lane constraint condition and a preset search step length. According to the invention, firstly, effectivemodeling is carried out, multiple lane constraint conditions reflecting a geometrical shape, traffic conditions and road resources of an intersection are set, a globally optimal solution is finally obtained under the multiple constraint conditions, collaborative optimization is carried out in time and space, and therefore the space-time resource utilization rate of the intersection is increased; and the phase number of the signal timing scheme of the main intersection is reduced, and road traffic efficiency is improved.

    本发明涉及一种左转主预信号联动的控制方法、装置及存储介质,该方法包括:根据多个道路参数,分别确定主交叉口流量乘数、子交叉口流量乘数以及加权平均带宽;针对主交叉口流量乘数、子交叉口流量乘数以及加权平均带宽进行加权处理,确定目标规划模型;根据多个道路参数,建立至少一个车道约束条件;根据至少一个车道约束条件和预设的搜索步长,确定目标规划模型的全局最优解。本发明首先进行有效的建模,并设置反映叉口的几何形状、交通条件、道路资源的多个车道约束条件,在多种约束条件下最终得到全局最优解,在时间和空间上协同优化,从而提高交叉口的时空资源利用率,减少主要交叉口的信号配时方案相位数,提升道路通行效率。
