摘要:

在缺乏有效的真实换道事故数据的情况下,基于交通冲突理论,分析车辆在换道过程不同阶段与周围车辆的潜在冲突形式。通过微观冲突风险指标推导、宏观换道风险特征提取和系统性换道风险分析,建立同时考虑潜在碰撞可能性与严重程度的换道风险综合量化方法。利用自然驾驶轨迹数据集,对风险综合量化方法进行应用试验分析。结果表明,所提出的量化方法能客观合理地反映不同类型、不同位置的换道风险特征,为智能车辆安全换道决策与规划提供了一种新思路。

Abstract:

In the absence of effective real lane change accident data, the potential conflict forms of vehicles with surrounding vehicles at different stages of complete lane change process are analyzed based on traffic conflict theory. Through the derivation of microscopic conflict risk indicators, the extraction of macroscopic lane change risk features and the analysis on systematic lane change risk, a comprehensive quantification method of lane change risk is established with concurrent considerations on the possibility and severity of potential collisions. An application test is conducted to analyze the comprehensive risk quantification method using the natural driving trajectory data set. The results show that the quantification method proposed can objectively and reasonably reflect the risk features of lane change of different types and locations, providing a new idea for the decision-making and planning of safe lane change of intelligent vehicles.
