Abstract:

分析了现有公交调度方法中大间隔发车、局部收敛与时间不协调等问题,以最大同时到站次数和最大同时到站车辆数量为优化目标,以末车定时、站点允许排队长度、服务质量、线路服务时间跨度为约束条件,建立了公交时刻优化方法,设计了基于网络选点规则和网络同步规则的求解算法。计算结果表明当公交网络中存在2条线路与2个站点且发车时间在30min内时,应用提出的方法,在2个站点共产生3次同步,线路1的发车时刻分别为第5、15、20、30min,线路2的发车时刻分别为第0、10、30min;与现有方法相比,同步次数减少1次,发车时刻完全分布于规定时间内,消除了剩余时间,获得了非均匀化的发车间隔,体现了同步的多样性。
