本文研究道路资源有限条件下车辆竞争与协作换道行为特性。在前人研究的基础上,对竞争换道行为进行了描述,并与协作换道行为进行了比较。采用视频拍摄和车辆轨迹提取软件获取了车辆换道数据。着重探讨了车辆换道距离和时间、骑线行驶距离和时间的内在联系,并对换道行为中车辆的接受间隙、速度变化、横向位移进行了分析。以实测数据为基础,得出竞争/协作换道行为下车辆换道接受间隙的分布函数,提出重合区域最小值法,得到竞争与协作换道接受间隙的临界值,并以此建立了不同间隙下车辆换道行为的概率模型。研究结果表明:竞争/协作换道接受间隙的临界取值为19.28 m,车辆间隙大于30 m时车辆选择协作换道的概率为94.49%以上。
This paper studies the characteristics of lane competition and collaboration lane changing under limited road resources. Based on the previous studies, the competitive lane change is described and compared with the cooperative lane change. Vehicle tracking data was acquired using video capture and vehicle track extraction software. The emphases are given to discuss the inherent relationship between lane changing distance and time, riding distance and time of lane changing, and the acceptance gap, speed variation and lateral displacement of lane changing vehicle. Based on the measured data, the distribution function of vehicle lane change clearance under competitive / cooperative lane change behavior was obtained. The minimum area convergence method was proposed to obtain the critical value of competition and cooperative lane change acceptance clearance. Based on this, different clearances Probability model of lane changing behavior of vehicles. The results show that the critical value of competition / cooperation lanes to receive clearance is 19.28 m, and the probability of vehicle selecting cooperative lane change is more than 94.49% when the vehicle clearance is greater than 30 m.
