| 摘 要： | 协调公交站点的服务能力与公交车停站需求,是提高城市交通系统运行效率的重要手段.本文在已知公交车运行线路、发车间隔、停车站点位置、停车站点泊位数信息,并假设公交车在道路路段上运行时间、停站点停驻时间满足概率分布条件下,研究整个城市公交站点的服务可靠性,得到了公交车站点服务可靠性概率计算公式,并定义了α-可靠度来衡量公交车站点服务可靠性.通过本研究发现:公交车站点相遇概率具有时间周期性,公交站点服务可靠性不仅与公交车运行线路的设置、发车间隔长短、停车站点位置设置、停车站点泊位数信息有关,还与交通系统中的路段旅行时间可靠性、公交车站点停车时间可靠性存在密切的联系.

| Abstract: | It is an important measure to improve the operation efficiency of the urban traffic system by coordinating the service capacities of bus stops and the parking demands of buses.Based on the bus routes,departure intervals of buses,sites of stops and the numbers of parking berths for buses at stops,this study analyzes the service reliabilities of bus stops in a whole city and proposes a formulas for calculating the service reliability of a bus stop,on the assumption that the travel time on the road segment and... |
