摘要
在城市道路交叉口实行公交优先控制可以提高公交效率及准点率,降低运营成本,吸引乘客,可缓解我国城市交通问题。介绍了基于乘客人均延误最小为目标,在单点交叉口被动公交优先控制理论的基础上,建立了被动公交优先的周期优化模型,结合现场实例,将现有交通控制条件下的效益分析结果与按公交优先的最佳周期时长的确定及效益分析进行比较,说明周期优化的可行性。
Traffic control methods to provide priority to transit vehicles at urban intersections could improve transit operations and schedule reliability,reduce operating costs,increase ridership and embody traffic equality.Based on the aim of the minimum delay per person and the theory of control strategy for passive transit priority,the optimum cycle mode of passive transit priority was established.Combined with the cases,the efficiency analysis result under the condition of current traffic controlling was compared with the certainty of the best cycle according to passive transit priority and its efficiency analysis,which proved the feasibility of the optimum cycle.
