Abstract
The parking attendant system, which was installed in June 2006 to employ certified citizens, is a drastic amendment of the Road Traffic Act regarding the on-street parking regulations. It was expected that this amendment would lead to a significant change in the parking behavior of drivers on roads. In this study, the effects of the installation of the new system are statistically shown based on the changes in parking time, purpose of parking, and behavior of leaving a car (a driver leaves a car, making the car empty, for a while), etc. The survey for this study was conducted three times: before, just after, and one year after the installation of the new system. As a result, expected and unexpected changes in parking behavior were observed. In addition, the queuing model was adopted for analyzing on-street parking behaviors, and the effects of the new system were discussed from the viewpoint of the reduction of cars wandering around to find parking space.
