摘要
为了在交叉口实现公交优先并降低对社会车辆的影响,提出一种在右转车道设置公交先行区的方法.进一步利用Matlab建立流量生成与双延误矩阵模型评价的仿真流程,对设置先行区前后的共用车道进行效益评价,并对其中的交通需求和车种比例进行分析.通过实例交叉口VISSIM的仿真结果得出,设置先行区后,右转车辆与共用车道相比平均延误降低41.03%,公交车辆与现状相比平均延误降低26.74%.通过敏感性分析可知,该文方法在高交通需求和公交车比例小于50%时都具有较好的兼容性.
Abstract
In order to prioritize buses at intersections and minimize the impact on regular vehicles,a method is proposed to establish bus priority zones in right-turn lanes.Further,a simulation process is developed using Matlab to evaluate the effectiveness of the shared lanes before and after the establishment of the priority zones,based on traffic generation and dual-delay matrix models.Analysis is conducted on traffic demand and vehicle proportions.Results from VISSIM simulation of a case intersection indicate that,after implementing the priority zones,the average delay for right-turning vehicles decreases by 41.03% compared to shared lanes,and the average delay for buses decreases by 26.74% compared to the existing situation.Sensitivity analysis shows that this method is compatible with high traffic demand and bus proportions below 50% .
