基于冲突复杂度的智能网联车辆在交叉路口的交通安全分析与评价方法研究OA

As a high-incidence area for urban traffic conflicts,intersections are critical for enhancing traffic safety and efficiency through safety risk analysis and evaluation of intelligent connected vehicles(ICVs).Aiming at the limitations of traditional evaluation methods,such as single research object and insufficient multi-source data fusion,a safety risk evaluation system for ICVs at intersections based on conflict complexity is proposed.Combined with traffic equivalent and the impact of intelligent network connection technology on traffic conflicts,an evaluation model is constructed.Traffic conflicts(including conflict intervention of ICVs)are quantified by conflict complexity,and the evaluation is completed by using the traffic safety city classification standard.Taking the intersection of Libuhu Avenue and Changzheng West Road in Nanchang as an example to verify the rationality of the model.The research results can provide theoretical support and quantitative basis for the optimization of ICV decision-making systems and the collaborative management and control of urban intersections.
