Abstract
Illegal parking is one of the factors to cause traffic congestion and traffic accidents. Therefore, it causes tremendous social cost such as time-loss due to the traffic congestion and loss of human recourses due to traffic accidents. In Japan, to decrease the occurrence of illegal parking, Road Traffic Law (RTL) was amended in June, 2006. The main purpose of the amendment is that to check illegally parked vehicles and put parking tickets on the vehicles are consigned to private sectors. The National Police Agency of Japan reported that the number of illegally parked vehicles has been decreasing, and that the use of the parking lot has been increasing. In order to continue these effects, we have to investigate the change in driver's consciousness before and after the amendment of RTL. Then, this research estimated parking place choice model using SP survey data, and clarified that the driver's consciousness had changed.
