Modeling the Effect of Parking Fare on Personal Car Use

In this paper, passenger behavior when travelling to business districts using their own cars, and when confronting various parking fares, is discussed. The nal goal is to determine the parking fare threshold (the price at which passengers would refrain from using their own cars) in the central business district of Tehran. Also, e ective variables that a ect passenger reaction at di erent levels of parking fare are evaluated. A logit model was made to predict passenger behavior using data gathered in di erent parking lots, located in the surveyed area. Data have been collected by a stated and revealed preferences method. Characteristics related to passengers and their trips, as well as their reaction to a rise in parking fares, were collected by a questionnaire. Analysis of the model showed that a 400 Tomans/hr increase in the hourly parking fare would eliminate the use of personal cars by the passengers (99% decreases in personal car use). It is concluded that travel time and passenger monthly income are the most in uential parameters a ecting personal car usage.
