This paper aims to improve the understanding of the drivers of customer satisfaction with public transport (PT). The methodology provides a relevant contribution to the previous studies since it highlights the complex interaction between the level and composition of satisfaction, negative social safety experiences (NSSEs), urban settings, and the PT mode used.Overall, PT users see the service attributes on-time performance, travel speed, and service frequency as the most important, followed by personnel/driver behaviour and vehicle tidiness. A generic policy aimed at achieving these attributes may yield favourable results with respect to satisfaction.Further, we demonstrate the influence of differences in customer characteristics on satisfaction. A policy aimed at increasing the service frequency and putting new vehicles into operation will probably lead specifically to more satisfied older people (>65), passengers travelling by regional train, and people living in dense urban areas.These findings may be of help to PTAs intending to exert an influence on the actions of PT operators, for instance by using them as a measuring rod in incentive contracts. 相似文献

The rapid pace of motorization throughout the world has changed travel behavior, which in turn has influenced every aspect
of transport operations. This impact has also increasingly challenged the future existence of such road-based urban public
transport as paratransit due to its characteristics and problems, especially in developing countries. Since creating satisfied
users can help retain paratransit’s existence, this research aims to explore user satisfaction with paratransit service in
order to anticipate future implications for its competition with motorization in Bandung, Indonesia. It establishes important
factors and attributes to explain user perceptions and priorities regarding the service. Its hypotheses explain how users
measure paratransit’s quality of service, inferring that they are likely to continue to use it. Even though users are dissatisfied
with several aspects of paratransit, and the impact of competition has been strong, loyal users can still be found. By considering
the findings, existing problems of inappropriate-quality service can be addressed to satisfy users’ expectations. The study
also suggests some anticipation of winning the competition with motorization. 相似文献

基于可拓方法的泥石流危险性评价 总被引:16,自引:0,他引:16
运用可拓学的物元理论、可拓集合论和关联函数,构建泥石流危险性评价的经典物元和节域物元,建立泥石流危险性评价的物元模型。应用建立的物元模型,选取泥石流规模、泥石流发生频率、流域面积、主沟长度、流域最大相对高差、流域切割密度、主沟床弯曲系数、泥砂补给段长度比、24 h最大降雨量、人口密度等10个因子作为泥石流危险性评价因子,对8条典型泥石流沟的危险性进行评价,获得客观合理的评价结果。与其它评价方法的对比结果表明:该方法能较真实地反映实际泥石流沟的危险性等级,证明可拓学理论应用于泥石流危险性评价的有效性和可行性。 相似文献
