摘要:
为分析加速车道几何参数对合流区交通状况的影响，基于实验方案和效率-冲突率评价指标，构建实验平台并标定对应参数，结合实际交通场景数据及速度偏差和交通冲突相关系数指标，验证实验平台有效性。结果表明：w，l随主线流量增大而增大，合流区交通状况逐步变好；随主线流量增大，在l=60 m时，w对合流区交通状况的影响较大且整体交通状况较差，而l相应增大后，w对交通状况影响较小。
Abstract:
In order to analyze the influence of the geometric parameters of acceleration lane on the traffic conditions in the confluence area,based on the experimental scheme and the evaluation index of efficiency-conflict rate,an experimental platform was constructed,then the corresponding parameters were calibrated,and the effectiveness of the experimental platform was verified combining with the actual traffic scene data and the correlation coefficient index of speed deviation and traffic conflict.The results showed that w and l increased with the increase of traffic flow in main line,and the traffic condition in the confluence area gradually improved.With the increase of traffic flow in main line,when l was 60 m,the influence of w on the traffic condition in the confluence area was greater,and the overall traffic condition was poor.When l increased accordingly,the influence of w on the traffic condition was less.
