Parking is an inevitable part of car use. A car needs two parking spaces, one is for long duration, where it is parked after all daily errands or activities are carried out-this is around the residential location most of the time, and the other is for short duration while carrying out daily errands or pursuing activities. This paper shows that parking spaces are significantly affected by the urban development and vice versa, as experienced in the case of Istanbul. Carried out in a fast developing and motorizing city Istanbul, the study highlights perplexities of parking behavior when streets are regarded as de facto free parking spaces for privately owned vehicles and parking policies. A model, accounting for night-time parking location choice of households among three alternatives: On-street parking, Off-street private parking and Paid parking, is developed in this study. It is concluded that without controlling parking behavior and regulating land-use and transport policies, parking problems will reach to a point of no solution under mass motorization.
