Item type:Item, Effect of Resource Allocation Policies on Urban Transport Diversity(2009) ;Feng, Cheng-Min ;Hsieh, Cheng-Hsien ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementMaximizing transport diversity is critical to the equitable achievement of stakeholder needs. Resource allocation policies help planners decide when and how to invest transportation infrastructure and services. However, policies for improving transport diversity are difficult to design, implement, and quantify because of the uncertainty, feedback interaction, and complexity of system relationships. This study proposes a hybrid model integrating system dynamics, cognitive maps, and a sensitivity model to tackle the problems. The model application is illustrated through an empirical study to enhance the managerial implications in the Taipei metropolitan area.Item type:Item, Effects of price promotions on potential consumers of high-speed rail(2013-12-01) ;Kuo, Yi-Wen ;Hsieh, Cheng-Hsien ;Feng, Cheng-Min ;Yeh, Wen-Ya運輸與物流管理系 註:原交通所+運管所Effects of price promotions for high-speed rail (HSR) on the choice behaviours of potential consumers are analysed for public transit marketing purposes. A questionnaire survey, with 300 valid samples collected from private vehicle drivers with long-distance trips through freeways, is conducted. Factor analysis is employed to determine the constructs of service quality, while a discrete choice model considering individual heterogeneity, namely a mixed logit model, with stated preference is utilised to explore the diversion of passengers from private vehicle drivers due to price promotions. Analytical results reveal that service qualities, socio-economic characteristics and price promotions significantly affect choice behaviours. Finally, some strategies are developed from these analytical results to help a HSR operator increase its market share.Item type:Item, Implications of Transport Diversity for Quality of Life(2009-03-01) ;Feng, Cheng-Min ;Hsieh, Cheng-Hsien ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementDifferent transport stakeholders have different needs for transport infrastructure and services. Meeting the needs of stakeholders implies a tradeoff of benefits and costs between supply and demand and creates issues of transport diversity. However, the literature has largely ignored these issues. This study aims to provide a framework evaluating transport diversity to promote quality of life. Transport diversity is defined as the satisfied level of stakeholder needs in this study and measured as the gap between the expected goal and present values of stakeholder needs in the form of the Shannon-Weaver index. Transport diversity can assess whether the level to which important needs are satisfied equitably, and monitor whether the transportation system is moving toward sustainability via confirming the targets and the basic level of quality of life. This study hopes that the conceptual framework developed can assist decision makers in understanding the relationship between transport diversity and sustainability, and provide a new assessment method for improvements in quality of life.Item type:Item, RESILIENCE DETERMINATION OF METROPOLITAN ROAD NETWORK BASED ON VULNERABILITY AND INTERDEPENDENCY ANALYSES(2012-01-01) ;Hsieh, Cheng-Hsien ;Feng, Cheng-Min ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementIncreasingly frequent and high-magnitude climatic extremes cause significant mortality, injury and property damage, warranting efforts to improve coping capacities based on identifying and alleviating socioeconomic inequalities and environmental vulnerabilities. Disruptions to transportation systems impair the ability to ensure sustainable daily operations and cause failures in other systems. Along with resource allocation and pre-evacuation, road networks profoundly impact disaster response and recovery, particularly emergent disaster logistics and islanding rescues. This study thus examines the resilience of road network from the perspectives of vulnerability and interdependency. Analytical results demonstrate that the level of service on adjacent links, connectivity, and accessibility to hospital emergency facilities significantly impact the resilience of metropolitan road networks. The method developed in this study can assist planners in understanding the assessment tools of road network resilience and help decision makers prioritize resource allocation to improve road network serviceability under hazardous conditions.Item type:Item, Road network vulnerability assessment based on fragile factor interdependencies in spatial-functional perspectives(2014-01-01) ;Hsieh, Cheng-Hsien ;Feng, Cheng-Min ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementRoad networks are instrumental in resource allocation and preevacuation, and profoundly affect disaster response and recovery, particularly emergent-disaster logistics and island rescues. Disruptions to road networks impair daily operations, irrespective of whether they are damaged by external forces or failures in interacting elements. However, functional interdependency is absent from transportation vulnerability assessments. This study thus constructed a framework to assess the interdependent vulnerability of road network failures. Based on eleven fragile factors developed in the literature and an empirical case study in the Taipei metropolitan area, road network vulnerability is determined by fuzzy cognitive maps and geographic information systems for functional and spatial interactions, respectively. The analytical results indicate that road network vulnerability is underestimated if the interdependency is neglected. Delay time on the shortest substitution, level of service on adjacent links, and inaccessibility to hospital emergency centers significantly affect vulnerability. Whereas certain socioeconomic resilience is performed in the short term, spatial-functional interdependency dilutes those effects in the long term. The framework developed facilitates decision makers in understanding interdependent vulnerabilities and adopting appropriate strategies to improve vulnerability.Item type:Item, Stakeholder perspective on urban transport system service quality(2010) ;Wang, Shu-Mei ;Feng, Cheng-Min ;Hsieh, Cheng-Hsien ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementDifferent transport stakeholders have different needs for transport infrastructure and services. Achieving stakeholder satisfaction implies a total quality management (TQM) that continuously improves service quality. However, few studies have discussed service quality in relation to urban transport systems. This study proposes an instrument based on SERVQUAL for measuring urban transport service quality from a stakeholder perspective. The proposed instrument is developed and tested through exploratory and confirmatory factor analyses. The gaps between stakeholder expectations and actual received and the gaps associated with stakeholders' expectations and the perceptions of these expectations by professionals are examined. Importance-performance analysis is used to construct a service attribute evaluation map for determining resource allocation to improve service quality. The application is illustrated through an empirical study to discuss the managerial implications in the Taipei metropolitan area. The analytical results reveal the existence of gaps and that stakeholders are more concerned with reliability and safety dimensions.Item type:Item, The highway resilience and vulnerability in Taiwan(2020-03-01) ;Hsieh, Cheng-Hsien ;Feng, Cheng-Min ;運輸與物流管理系 註:原交通所+運管所Department of Transportation and Logistics ManagementOwing to extreme climatic events caused by global environmental changes, the frequency and magnitude of natural hazards in Taiwan have increased in recent years, leading to deaths, injuries, and substantial damages to properties. Disruptions to critical infrastructures have impaired the ability to ensure sustainable daily operations and have caused further failures in other systems. Along with resource allocation and pre-evacuation, highway networks profoundly impact disaster response and recovery, particularly emergency disaster logistics and rescues. This study reviews the highway vulnerability assessments in Taiwan and examines the resilience of highway networks in regard to failures from the perspectives of interdependency. Analytical results demonstrate that the accessibility of emergency medical facilities plays an essential role in highway resilience in Taiwan. Moreover, the connectivity is critical for metropolitan road network resilience, whereas remote highway resilience is associated with the exposures with insufficient self-protection capacities. The proposed method can assist planners in understanding the assessment tools for highway resilience and help decision makers prioritise their adaptation strategies to improve serviceability of the road network during hazardous conditions.Item type:Item, Using Cusp Catastrophe Theory to Model Pick-up Point Choice Behavior for Online Bookstore Shopper(2010) ;Huang, Yu-Kai ;Fan, Wei-Shang ;Hsieh, Cheng-Hsien ;Lan, Chun-HsiungChang, Ruei-ShiuanOrdering books on the Internet is obviously becoming a significant market. Retailing delivery (RD) service provides consumers with a self pick-up approach, so it is popular for those who cannot conveniently use home delivery service. E-service quality and logistics service quality are the key issues in e-commerce. A nonlinear model of loyalty is suggested by past studies. The main purpose of this study is to explore how of the logistics service quality and switching cost influence the pick-up point choice behavior by using a catastrophe model. Firstly, the latent variable is defined in the confirmatory factor analysis (CFA). Secondly, the catastrophe model was used to analyze the linkages between service quality and switching cost on pick-up point service loyalty. The results indicated that the switching cost plays the splitting factor in the catastrophe model, and a high switching cost makes the discontinuous choice behavior, implications of these results for practice and research are provided.
