【摘要】：针对单条公交线路双向及单向客流分布的不均衡性,考虑我国大城市公交企业普遍依靠政府补贴,在实际运营中存在预算限制的情况,以社会总体效益最优为目标,建立了对区间车和双向全程车的发车频率及区间车折返位置同时进行优化的组合调度模型,探讨了预算限制对优化调度的影响,证明了预算限制相当于减少了乘客的时间价值,分析了预算限制下组合调度最优发车频率、折返点位置和系统成本的关系,并与单一调度进行对比。结果表明:在客流分布不均衡和预算限制的情况下,相比单一调度,组合调度能有效减少系统成本和乘客平均出行时间,节省运力,降低车辆拥挤,提高服务水平。在预算限制下,可以通过组合策略的实施,使出行乘客和运营企业都获益。
[Abstract]:In view of the unbalanced distribution of two-way and one-way passenger flow on a single bus line, considering the fact that public transport enterprises in large cities in China generally rely on government subsidies and have budget constraints in actual operation, the goal is to optimize the overall social benefit, In this paper, a combined scheduling model is established to optimize the starting frequency and the return position of interval vehicles and bi-directional vehicles, and the influence of budget constraints on optimal scheduling is discussed. It is proved that the budget limits are equivalent to reducing the time value of passengers. The relationship among optimal departure frequency, rebate point location and system cost under budget constraints is analyzed and compared with single dispatch. The results show that under the condition of unbalanced passenger flow distribution and budget constraints, compared with single scheduling, combined scheduling can effectively reduce system cost and average passenger travel time, save transportation capacity, reduce vehicle congestion and improve service level. Under budget constraints, travel passengers and operators can benefit from the implementation of combined strategies.
