Interaction of urban fringe and transportation system: Istanbul case

Abstract

Nowadays, urban sprawl is common problem of all cities. Decentralization of housing with low density and jobs into urban fringe areas is considerable development Sprawl is blamed a wide range of problems likewise wasteful use of land, air pollution, dependence on car, increased traffic congestion, lengthened travel distance and time, but it is not clear explaining how urban sprawl affects travel behavior in Turkey?The aim of the thesis is to identify the influence and importance of urban sprawl on travel behavior in Turkey. Firstly literature survey on urban sprawl and urban fringe was examined. Geographic Information System was used to define and map urban sprawl. Daily trip production in sprawl and urban core was analyzed. In addition daily travel behavior was inquired. For this study, 2007 İstanbul Master Plan Household and O-D survey was also used. It allows comparisons travel behavior between sprawl and urban core area.The results confirmed that there is no much difference on socio economic situation between people living in urban sprawl area and people living in urban core area. However using of private car is higher rate in sprawl area than urban core. In addition sprawl population drive more time and distance than urban population. The results provide important insights into the importance of sprawl on transportation and suggest that transportation system can be adversely affected to the extent that cities continue to expand to urban sprawl areas as wanton.As a consequence, sprawl effects İstanbul transportation as negative because sprawl affects travel behavior. This situation creates increased private car ownerships and traffic congestion. To solve this problem and many other problems in transportation related sprawl, studies on transportation and master planning should be considered sprawl fact.
