User response to parking policy change: A comparison of stated and revealed preference data

• We examined the impact of increased parking price on parking demand.
• We compared RP and SP data concerning parking price elasticity and demand.
• An increase in price decreases the number of users, especially commuters.
• Generally there is no difference in the results obtained from RP and SP methods.

In the available literature it is difficult to determine the impact of the real parking price change on parking demand–probably because the application of such measures requires more recent data. In any case, in the future, once this measure is defined, quantification of the effects should be expected, which will be of great significance for further outlooks on this policy. This paper studies and quantifies the impact of an increase in parking price on the demand and operation of parking garages in central Belgrade. In addition, the paper investigates to what extent the planned demand, estimated on the basis of users' attitudes toward parking price, is in agreement with the actual demand after the price change. Confirmed agreement between the forecasted and actual demand contributes to a greater reliability in achieving the expected effects on the basis of the price determined through predicted demand.
