The invention discloses a tramcar network green wave coordination control method and device. A mixed integer linear programming model constructed by the method aims to maximize the weighted sum of thebidirectional green wave bandwidths of social vehicles; wherein model constraints comprise intersection phase sequence constraints, social vehicle and tramcar green wave constraints, social vehicle and tramcar interaction constraints, intersection trunk line intersection constraints, network outer ring closed-loop constraints and the like; and the constraints are relaxed through a 0-1 variable representing whether the green wave of a road section is interrupted or not, so that the green wave bandwidth of a tramcar is ensured to meet the traffic demand while the green wave bandwidth of socialvehicles is expanded as much as possible. According to the method, tramcar green waves of the whole road network rather than a single line can be optimized, the green wave band can reflect the road flow demand, and green waves of part of the road section can be interrupted under necessary conditions so as to achieve a globally optimal solution. And finally, cooperative, efficient and smooth operation of the tramcar and the social vehicle in the whole road network is realized.
本发明公开了一种有轨电车网络绿波协调控制方法与装置,本发明方法所构建的混合整数线性规划模型以最大化社会车辆双向绿波带宽加权之和为目标,模型约束包括交叉口相序约束、社会车辆及有轨电车绿波约束、社会车辆有轨电车交互约束、交叉口干线交叉约束和网络外圈闭环约束条件等,并通过表示路段绿波是否打断的0‑1变量对约束进行松弛,在尽可能扩大社会车辆绿波带宽的同时,保证有轨电车绿波带宽满足通行需求。本发明能够对整个路网而非单条线路的有轨电车绿波实行优化,并且绿波带能够反映道路流量需求的大小,并且在必要条件下可以打断部分路段的绿波,以达到全局最优解。最终实现了整个道路网络中有轨电车和社会车辆的协同高效流畅运行。
