The invention discloses a road side unit layout method for a vehicle-road cooperation environment, and the method comprises the steps: dividing travelers into non-network-connected users and network-connected users according to a travel mode, and abstracting a road network into a directed graph; according to the non-network-connected vehicle equivalent coefficients, fitting the function curve of the mean value and the variance of the non-network-connected vehicle equivalent coefficients with respect to the network-connected vehicle mixing rate; according to the road section travel time expectation, a mixed traffic network balance condition is utilized to represent path selection behaviors of the network-connected vehicles and the non-network-connected vehicles; a mixed integer linear programming model is used for representing a road side unit layout problem oriented to the vehicle-road cooperation environment; and solving the mixed integer linear programming model by using a Gurobi solver to obtain the layout position of the roadside unit in the road network. According to the invention, the stable operation of each function of the network connection vehicle is supported through the arrangement of the road side unit, the common improvement of the urban road network passing efficiency and the system reliability is realized, and a reference basis is provided for intelligent network connection facility planning in a vehicle-road cooperation environment.

    本发明公开了一种面向车路协同环境的路侧单元布设方法,根据出行方式将出行者分为非网联用户和网联用户,并将路网抽象为有向图;根据非网联车当量系数,对非网联车当量系数的均值、方差关于网联车混入率的函数曲线进行拟合;根据路段旅行时间期望,利用混合交通网络均衡条件表征网联车与非网联车的路径选择行为;利用混合整数线性规划模型表征面向车路协同环境的路侧单元布设问题;使用Gurobi求解器求解混合整数线性规划模型,得到路侧单元在路网中的布设位置。本发明通过路侧单元的布设支持网联车各项功能的稳定运行,实现城市路网通行效率与系统可靠性的共同提升,为车路协同环境下的智能网联设施规划提供参考依据。
