城市轨道列车发车间隔的优化方法研究

Study on Optimization Method of Departure Interval of Urban Rail Transit Train

在城市轨道交通中,考虑乘客和运营商两方面的利益,以车站等候人数最少和运营商经济效益最高为优化目标,建立了发车间隔优化模型。基于模糊目标规划,利用lingo软件对模型进行求解。在实际生活中,基于客流聚集特征和线路运营之间的协调关系,建立的城市轨道列车发车间隔优化模型,在安全运营列车的条件下对于提高线路运营效率、减小交通压力有非常重要的意义。

In the urban rail transit considering the interests of both passengers and operators,the optimization model of the departure interval is established based on the minimum number of passengers waiting for the station and the highest economic benefit of the operators. Based on the fuzzy goal programming,the lingo software is used to solve the model.In the real life,the optimization model of urban rail transit interval is established based on the coordination relationship between passenger flow characteristics and line operation. The model is very important for improving the operation efficiency and reducing the traffic pressure under the condition of safe operation of trains.
