Sprawl is a common label for the low-density, auto-oriented spread of metropolitan regions pervasive throughout the United States. Sprawling urban settlement patterns have resulted in increasing social costs such as traffic congestion and environmental degradation and pollution, as well as impedance of social and spatial integration. The urban spatial form is related to the transportation networks in cities. this structure that have the collaborative conjunction between its elements including streets, main centers of human activities and the land uses, effects the reduction of urban environmental pollutions. TOD is a planning technique that aims to reduce automobile use and promote the use of public transit and human-powered transportation modes through high density, mixed use, environmentally-friendly development within areas of walking distance from transit centers. Fereidunkenar is a city in the North of Iran near the Mazandaran Sea. The problem is that, by increasing the population and the potential for attracting tourism because of the landscapes and recreational spaces in the North of Fereidunkenar, the depth of his city would increase. So it is necessary to prepare the suitable transportation system that is responsible to the access of all citizens to the basic activities. This article explains the theoretical framework for use of transit oriented development especially in cities with linear spatial structure and evaluate the spatial structure in Fereidunkenar to determine the application of the concept TOD in this city.
