【 摘 要 】

Faced with the challenge of providingadequate transport services with limited resources, citieshave, for several decades, been investing in IntelligentTransportation Systems (ITS). ITS utilize Information andCommunications Technology (ICT) to make more efficient useof existing transport infrastructure with the aim ofimproving transport services and reducing congestion,accidents, and air pollution. In the past two decades, withthe rapid advancement of ICT and intensive advocacy from bigtechnology vendors, the concept of ‘smart cities’ has gainedgreat popularity and many cities have started to undertake amore holistic approach to improving urban services usingtechnology in the name of smart city initiatives. Sectiontwo introduces these themes, which serve as the analyticalframework to understand how smart mobility investments leadto energy savings. The comparison in the search forsimilarities among the case studies and interviews helped usdevelop a conceptual model, emphasizing cause and effect andpresented in section three, of how ITS deployment andoperation in the context of smart cities leads to energysaving benefits. This conceptual model is presented withdetailed discussions of institutional, technological, andphysical conditions at each step in the model. Section fourfocuses on energy savings with quantitative evidence ofenergy saving potential of ITS investments collected fromliterature and case studies. Section five links the resultsof this study to the Wuhan Integrated Transport DevelopmentProject and how the knowledge has been incorporated intoproject design. To further explore the energy efficiencypotential of Wuhan and to mainstream ITS and smart transportsolutions as a source of achieving energy efficiency usingresults of this study, a TRACE analysis was also completedas part of this research effort. This analysis focused onthe passenger transport sector. Finally, policyrecommendations on the major conditions under which ITSinvestments in the context of smart cities achieve energysavings are summarized in Section 6 with specificimplications for cities in the developing countries.
