Bisiklet yollarının coğrafi bilgi sistemleri ile mekansal analizi ve yeterliliklerinin sorgulanması - İzmir örneği

The rapid population growth in cities today leads to an increase in population density. Rapid constuction that results from population density seperates the urban spaces and causes transportation problems. Besides, the increase in the use of motor vehicles causes many environmental problems. Air and noise pollution caused by vehicle traffic affects both human health and urban life negatively. As a healthier, more economical, environmentally and eco friendly mode of transport, cycling is considered to be a mode of transport with many additional benefits. Within the scope of the thesis, the characteristics of the city center of İzmir, urban transportation infrastructure and the existing bicycle routes were examined and the assessments related to the whole urban area was determined. In this study, the amount of existing bicycle paths, the spatial distribution of bicycles network and quality of the existing bicycle paths in the city were determined by means of geographical information system. Then, a spatial-database containing coordinated graphical data was created and spatial-analysis was performed on this database using geographic information systems. The data related to the population, land use and transportation network infrastructure, which constitute the other parameters related to urban space, was added as an object-layer in the spatial-database and the competencies of the city-wide bicycle paths were questioned by overlapping with the object-layer containing the existing bicycle paths. Another aim of the study is to create a base for the planning studies in the city of İzmir and in this field, to be a guide for a more efficient planning process and to raise awareness on this issue.
