The role of passenger modal shift nodes in the interaction between land use andtransport system

Risultato della ricerca: Chapter


In the last years, we have observed a sub-urbanization process or “sprawl” process (lowdensity of inhabitants), caused by new economic and production conditions, a new pattern ofsocial relationships and the widespread use of private car for travelling.Commuters need to reach quickly their own destinations and the traffic-related problems incentral areas require multimodal platforms as nodes of an integrated transport system to fostercar-public transport interchange.The optimal location and design of modal shift nodes, for potential users involved inmultimodal transfers within an urban or metropolitan context, is one of the most importantissues in transport system planning.Several methods have been developed to deal with this topic. The basic idea is to locate suchnodes in areas of adequate size, well connected to the road network and public transit in orderto minimise the time required for the transfer, taking into account the variation of transportdemand under the various steps of decision-making process (generation, distribution, modeand route choice).The aim of the proposed research is to tackle the aforesaid planning issue through amethodological approach focusing on a land use-related aspect: the attractiveness of such2modal shift nodes in relation to their potential territorial role as providers of several servicesother than mobility-related utilities.In particular, the metropolitan area of Palermo and its outskirts, which is taking theconnotation of an expanded city, will be an interesting case study to test for the goodness ofthe proposed methodology.The results showed in this paper define the criteria for the optimal location of intermodalnodes within a context characterized by a dispersed urban area composed of manymunicipalities, based on also the role that can be played by each node as multi-service centreaffecting passenger travel behaviour. Furthermore, the paper describes the modellingframework we are going to apply.
