【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。更多还原

【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%.更多还原
