【摘要】：直右共用车道是交叉口进口道内一种常见的车道形式。其提高了交叉口直行车辆在绿灯期间的通过率,但直行红灯期间直右共用车道上停车等待的直行车辆将增加右转车辆延误。如何在保证直行车辆运行效率的同时尽量减少右转车辆延误将对提高交叉口整体运行效率有现实意义。为解决这一问题,提出一种预信号控制方法。在现有研究成果上,结合直右共用车道所在进口道特性,建立预信号控制方法使用前后不同的进口道车辆延误模型,分析预信号控制方法效果。通过数据调查,获取直右共用车道所在进口道的几何及交通特征。分析其区别于普通交叉口进口道的两个关键指标,即直右共用车道首停车时刻以及首停车出现后直右共用车道车辆到达率。基于现有延误模型,结合直右共用车道所在进口道车辆运行特性,建立适用于该种类型进口道的车辆延误模型,应用两个关键指标的分析结果标定模型参数。利用该模型求取直右共用车道进口道车辆延误,并通过对比,验证延误模型准确性。针对直右共用车道延误较高的问题,提出一种预信号控制方法。运用预信号理论,制定预信号条件下直右共用车道及其紧邻直行车道上直行车辆的行驶规则,给出确定提示变道线标志位置的计算公式,协同预信号与主信号的配时方案。最后,根据预信号控制方法下进口道车辆运行特性,建立预信号控制下的交叉口进口道延误模型。通过对比预信号控制方法使用前后的两个进口道延误模型,评价预信号控制方法效果,并根据评价结果确定预信号控制方法适用条件。
[Abstract]:Right-to-right lane is a common lane form in intersections. It improves the passing rate of the direct vehicles at the intersection during the green light period, but it will increase the delay of the right-turn vehicles waiting in the straight right common lane during the straight red light period. It is of practical significance to improve the overall operational efficiency of intersection by how to reduce the delay of right-turn vehicles while ensuring the running efficiency of direct vehicles. In order to solve this problem, a presignal control method is proposed. Based on the existing research results, different vehicle delay models before and after the use of the pre-signal control method are established, and the effect of the pre-signal control method is analyzed. Through the data survey, the geometry and traffic characteristics of the right-right access lane are obtained. This paper analyzes two key indexes which are different from the common intersections, that is, the first stop time of the straight right common lane and the vehicle arrival rate of the straight right common lane after the first stop appears. Based on the existing delay model and combined with the running characteristics of the vehicle in the straight right common lane, the vehicle delay model suitable for this type of entrance lane is established, and the parameters of the model are calibrated by using the analysis results of two key indexes. The model is used to calculate the vehicle delay in the right common lane, and the accuracy of the delay model is verified by comparison. In order to solve the problem of high delay of right-straight shared lane, a pre-signal control method is proposed. Based on the presignal theory, the driving rules of the straight right common lane and its adjacent straight lane under the condition of presignal are established, and the calculation formula for determining the sign position of the signal-changing lane is given, and the coordination scheme of the pre-signal and the main signal is given. Finally, according to the operating characteristics of the vehicle under the pre-signal control method, the delay model of the intersection entrance under the pre-signal control is established. By comparing two inlet channel delay models before and after using the pre-signal control method, the effect of the pre-signal control method is evaluated, and the applicable conditions of the pre-signal control method are determined according to the evaluation results.
