基于节点重要度的MAST公交站布设评价研究DOI: DOI:10.14081/j.cnki.hgdxb.2018.06.015 Keywords: MAST, 节点重要度, 公交站评价, 公交站布设, 熵权法MAST, nodeimportance, busstopevaluation, busstoplayout, entropyweightmethod Abstract: 在常规公交站评价的基础上,引入复杂网络中节点重要度概念,结合MAST公交特性,提出了一种基于 节点重要度的MAST公交站评价方法.将节点度、公交站变通性、公交站客流强度、客流时空特性、到站便捷 性作为评价指标,并利用熵权法求得指标权重,得到公交站重要度,最终获得评价值.通过具体算例对本方 法予以验证,并与已有研究决策做了对比.结果表明,本方法是合理可行的,能够在一定程度上为评价MAST 公交站布设的合理性提供决策支持,并为优化公交站布设和线路规划提供依据.BasedonbusstopevaluationofFixed-RouteTransit,theconceptofnodeimportanceincomplexnetworks wasintroduced.BycombiningthecharacteristicsofMAST,anevaluationmethodofMASTstopbasedonnodeimpor? tancewasproposed.Nodedegree,busstopflexibility,passengerflowstrengthofbusstop,passengerflowtime-space characteristicsandconvenienceofarrivalatstopwereallusedastheevaluationindex.Theindexweightsweredeter? minedaccordingtotheentropyweightmethod,andtheimportancedegreesofbusstopwereobtainedforsolvingevalua? tionvalue.Finally,themethodwasverifiedbyaspecificexampleandcomparedwiththeexistingresearchmethod.More? over,theresultsshowthatthismethodisfeasible.Itcanprovidesupportatsomeextentstoevaluatetherationalityof MASTbusstoplayoutandprovidethebasisforoptimizingthebusstoplayoutandbuslineplanning.
