Limited off-road parking capacities in urban regions leads to increasing roadside parking demand in Turkey, which sometimes occurs in illegal or hazardous patterns. In the absence of strict parking management policies and regulation, lack of enforcement for illegal parking results in unregulated parking demand occupying road capacity, which is threatening the traffic management and safety in cities. Before parking management policies are developed, it is crucial to monitor the impact of roadside parking on urban road capacity, which is the focus of this thesis. Data collected for different patterns of roadside parking is processed to calculate the resulting net road width (NRW) utilizing advanced Geographic Information Systems (GIS) technologies. Video data of parked vehicles taken at the same time with the GPS track record of the observation vehicle is used with a custom-developed Windows Forms application tool, which allows semi-automatic detection of parked vehicles and violations on both divided and undivided corridors. As travel demand changes over space and time in a day, so does the parking demand; thus, the NRW indicator becomes a parameter which can be mapped dynamically. A case study in 100. Yıl neighborhood in Ankara, showed that due to parking, some road segments were narrowed to a NRW less than one lane, while along some corridors parking on both sides of the divided road segments led to traffic flow capacity of one-lane. Simple structure of the approach supported by Python scripts, enables quick analysis of roadside parking and its impact.
