摘要
针对城市轨道交通线网规模单一,计算方法结果存在明显差异,解释不全面的问题,建立一种基于熵权的轨道交通线网规模计算模型,综合考虑交通需求法、回归分析法、线网覆盖法和建设能力分析法等常用的轨道交通线网规模计算方法,有效提升轨道交通线网规模的合理性。将所建模型应用于某市轨道交通线网规模的计算,确定线网的合理规模,在此基础上拟定某市轨道交通线网3个规划方案,并采用层次分析法对各方案进行综合评价,得到最优的该市轨道交通线网方案。
Aiming at the problem that there are obvious differences in the result of single calculation method of urban rail transit network scale and the incomplete explanation, a calculation model of rail transit network scale is established based on entropy weight. The commonly-used calculation methods of rail transit network scale such as the traffic demand method, regression analysis method, network coverage method and construction capability analysis method and so on, are considered effectively to improve the rationality of rail transit network scale. This model is applied to the calculation of rail transit network scale in a city to determine the reasonable scale of the network, on the basis of which three planning schemes of rail transit network of the city are constructed. The hierarchical analysis method is used to evaluate each scheme synthetically, and the optimized scheme of rail transit network of the city is obtained.
