The invention discloses a site selection method for a vehicle-road cooperation intersection in an urban road network. The site selection method comprises the following steps: 1, calculating traffic capacity of roads under different network connection vehicle proportions; 2, calculating the passing time of the road under different network connection vehicle proportions; 3, traffic flow distribution is carried out in combination with travel behaviors of a network-connected automatic driving vehicle and a human-driven vehicle in a city; 4, restraining the construction number of the vehicle-road cooperative intersections according to the investment cost; 5, calculating to obtain the passing efficiency of different vehicle-road cooperative intersections under the preset condition; 6, calculating to obtain the betweenness centrality of the road network under the preset condition of different vehicle-road cooperative intersections; and 7, obtaining an optimal vehicle-road cooperation intersection site selection scheme through iterative calculation. According to the urban road network vehicle-road cooperation intersection site selection method provided by the invention, the optimal node for constructing the vehicle-road cooperation intersection can be selected from the complex urban road network, and the urban traffic planning can be effectively met.
本发明公开了一种城市路网中车路协同交叉口的选址方法,包括:1、计算不同网联车比例下道路的通行能力;2、计算不同网联车比例下道路的通行时间;3、结合城市中网联自动驾驶车辆和人驾车辆的出行行为,进行交通流量分配;4、根据投资成本约束车路协同交叉口建设数量;5、计算得到不同车路协同交叉口预设情况下的通行效率;6、计算得到不同车路协同交叉口预设情况下路网的介数中心性;7、通过迭代计算获得最优的车路协同交叉口选址方案。本发明提出的城市路网车路协同交叉口选址方法有助于在错综复杂的城市路网中选择出建设车路协同交叉口的最佳节点,能够有效地服务于城市交通规划的需要。
