Abstract
This article presents a parking performance function which indicates a degree of parking congestion and evaluates the level of parking service. The function represents the relationship between parking waiting time and user density in a parking facility with constant capacity. The functional form of multi-server model which we propose is very simple and useful compared with the theoretical queueing model. But the function is certainly logical one, since it is formulated on the basis of the queueing theory and includes the probability of occurrence of waiting. The empirical study shows that the parking performance function is statistically significant. We propose that the function should be used with a parking choice model in the framework of stochastic user equilibrium for parking use.
