基于博弈-可拓云的地铁-常规公交换乘服务评价

Evaluation of Subway Conventional Bus Transfer Service Based on Game Extension Cloud

为了解决地铁与常规公交换乘服务评价方法的单一性和滞后性等问题,提出一种博弈-可拓云组合模型。结合“全、简、精、实”四类原则构建评价指标体系,分别利用层次分析法、CRITIC法、博弈论确定各项指标的主、客综合权重,并将数值代入可拓云模型实现二者的结合。以石家庄地铁为例,对辖区三条线路与常规公交间的换乘服务进行综合评价,结果显示:1、2、3号线的分数均处于[70,90)范围内,属于良好等级。评价结果与该市地铁-常规公交的运营现状相符,验证了组合模型的可行性与普适性,该结果对科学制定精准化的公共交通换乘服务政策提供参考。

To address the issues of singularity and lag in the evaluation methods for subway and conventional bus transfer services,a game extension cloud combination model is proposed.Firstly,an evaluation index system is constructed based on the four principles of"completeness,simplicity,precision,and practicality".Secondly,the Analytic Hierarchy Process,CRITIC method,and game theory are used to determine the main,passenger,and comprehensive weights of each indicator,and numerical values are applied to the extension cloud model to achieve a combination of the two.Finally,the Shijiazhuang Metro is taken as an example,and a comprehensive evaluation is conducted on the transfer services between its three lines and conventional public transportation.The results show that the scores of Lines 1,2,and 3 are all within the range of[70,90),belonging to a good level,which is consistent with the current operation status of the city subway conventional public transportation system.This verifies the feasibility and universality of the combined model.The results in the article are conducive to the scientific formulation of precise public transportation transfer service policies.
