The invention provides an intersection overflow prevention signal optimization control method based on network connection vehicle data, belongs to the technical field of traffic management, and aims at the situation that the traffic capacity of a downstream road section of an intersection is suddenly reduced due to emergencies on the basis of signal timing of a traditional double-loop control structure. Through seven steps of traffic flow parameter fitting, traffic flow error fitting, entrance lane queuing length calculation, entrance lane traffic demand calculation, exit lane residual capacity calculation at the current moment, exit lane residual capacity prediction at the future moment and model prediction signal control, the purpose of improving the intersection passing efficiency on the basis of overflow prevention is achieved. The method can be suitable for intersection overflow prevention under the condition that the traffic flow and the bottleneck traffic capacity are unknown, so that the overflow risk coping capacity of the intersection signal control method is improved, and the traffic efficiency of the intersection is improved.

    本发明提供一种基于网联车辆数据的交叉口溢流预防信号优化控制方法,属于交通管理技术领域,针对交叉口下游路段由于突发事件通行能力骤降的情况,在传统双环控制结构的信号配时基础上,通过交通流参数拟合、交通流误差拟合、进口道排队长度计算、进口道交通需求计算、当前时刻出口道剩余容量计算、未来时刻出口道剩余容量预测和模型预测信号控制七个步骤,达到在预防溢流的基础上提高交叉口通行效率的目的。该方法可适用于交通流量和瓶颈通行能力均未知情况下的交叉口溢流预防,从而提高了交叉口信号控制方法应对溢流风险的能力,提升了交叉口的通行效率。
