The invention provides a multi-path main road signal cooperative control method considering speed fluctuation, and the method comprises the steps: firstly collecting traffic data, including road network geometric data, traffic flow data and signal control data, and determining a plurality of main paths according to the traffic flow data; then, based on the running speed of each vehicle on each main path, the vehicle running average speed and the speed fluctuation quantity on each main path are calculated; and finally, constructing a signal control optimization model: constructing a target function by taking weighted green wave bandwidth maximization of all paths as a target, adding a loop integer constraint, an interference constraint, a speed fluctuation space-time constraint, a highest speed fluctuation constraint and a lowest speed fluctuation constraint, solving the signal control optimization model, and obtaining an optimized signal period and green wave bandwidth. And outputting the optimized signal timing strategy. The signal timing generated by the method has a good prospect in the aspect of reducing travel delay and parking times, and a better multi-path collaborative effect can be realized.
本发明提供一种考虑速度波动的多路径主干道信号协同控制方法,包括首先采集交通数据,包括路网几何数据、交通流量数据、以及信号控制数据,根据交通流量数据确定若干条主要路径。然后基于各个主要路径上每辆车的行驶速度,计算各主要路径上的车辆行驶平均速度和速度波动量。最后构建信号控制优化模型:以所有路径的加权绿波带宽最大化为目标,构建目标函数,同时添加环路整数约束、干扰约束、速度波动时空约束、最高速度波动约束、最低速度波动约束,求解信号控制优化模型,获得优化信号周期和绿波带宽,输出优化的信号配时策略。本发明的方法生成的信号配时在减少行程延迟和停车次数方面具有良好前景,能够实现更好的多路径协同效果。
