The economic growth affects the transportation in such a way that causes traffic problems as well as congestion especially for developing countries. Many different parameters caused the traffic congestion such as insufficient transportation, network infrastructure, network capacity, unexpected increase in traffic demand, unplanned and rapid urbanization, and failure in use of the existing capacity. Essentially, integration of various mode is important to handle the high traffic demand. Park and Ride (PnR) facility is an important application in urban transport planning, that have public transportation priority, because it integrates the private car and public transportation to decrease traffic congestion and the environmental effect of traffic within the downtown. Istanbul Metropolitan Municipality affiliates ISPARK operated PnR facilities in Istanbul. This study examines PnR facilities located in Istanbul using Geographic Information System (GIS). These PnR facilities are classified according to their capacity, connected public transport mode (bus, subway, and maritime) and turnover rates. PnR facilities are evaluated using GIS with these parameters and recommendations are presented for PnR facilities location and integration with other transportation systems.
