The invention provides an intersection topology network dynamic construction method for network connection cooperative driving. The method comprises the following steps: constructing a vehicle intersection interaction relationship dynamic topological graph; acquiring vehicle data in real time, and updating node states in the topological graph; the method comprises the following steps: acquiring a driving intention of a vehicle in real time, carrying out conflict monitoring according to the driving intention of the vehicle and a driving path of vehicle state information, if there is a conflict between the vehicles, calculating the weight between the vehicles having the conflict, and dynamically adjusting a node and side relationship in a vehicle intersection interaction relationship dynamic topological graph according to a calculation result. The potential conflict risk between different vehicles is represented in a side weight form; and obtaining a traffic network complexity measurement index from the dynamically adjusted topological graph, and formulating a traffic management and optimization strategy by analyzing the traffic network complexity measurement index. According to the method, the safety of the intersection can be improved, traffic delay and congestion are effectively reduced, and the toughness and efficiency of the whole traffic system are improved.

    本发明提供一种面向网联协同驾驶的交叉口拓扑网络动态构建方法,包括:构建车辆交叉口交互关系动态拓扑图;实时获取车辆数据,更新拓扑图中节点状态;实时获取车辆的驾驶意图,根据车辆驾驶意图和车辆状态信息的行驶路径,进行冲突监测,若车辆之间存在冲突,则计算存在冲突车辆之间的权重,并根据计算结果动态调整车辆交叉口交互关系动态拓扑图中的节点和边关系,以边的权重形式表示不同车辆之间潜在的冲突风险;从动态调整后的拓扑图中获取交通网络复杂性度量指标,通过分析交通网络复杂性度量指标,制定交通管理和优化策略。本发明能提高交叉口的安全性,有效减少交通延误和拥堵,提升整个交通系统的韧性和效率。
