摘要
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。
The present study aims to investigate the cooperative / competitive lane-changing behavior characteristics in the limited road resources. Based on the predecessors＇ researches,the competitive lanechanging behavior is described,and compared with the cooperative lane-changing behavior. The lanechanging data are obtained by video capture and vehicle trajectory extraction. The internal relations among lane-changing space and time,trans-line ride（TLR） space and time are discussed,and acceptance gap,velocity change of object vehicle,horizontal displacement of lag vehicle are analyzed. Based on the measured data,the distribution functions about the acceptance gap of cooperative / competitive lane-changing are obtained. The critical value of the acceptance gap of cooperative / competitive lane-changing is extracted through the proposed method of minimum overlap area value,and the lane-changing behavior probability model for different acceptance gaps is established accordingly. The research result indicates the critical value of the acceptance gap of cooperative / competitive lane-changing is 19. 28 m,the probability of cooperative lane-changing is more than 94. 49% when the gap is more than 30 m.
