An Analysis of the Impact of Consolidation of Parking Lots Focusing on Walking Distance for Parking Users

Abstract

In Japan, the shortage of parking lots became apparent until the bubble economy period with high economic growth. Hence, it caused the problem of illegal parking on the streets. In order to solve this problem, off-street parking lots were promoted to develop around Japan. However, as the area occupied by parking lots in the city gradually increased, the utilization rate of off-street parking lots declined yearly. Hereafter, it is necessary to optimize and consolidate excess parking lots, but the impacts of consolidation of parking lots for users have not been analyzed in existing studies. Therefore, in this study, users' parking choice behavior was clarified first, and the impacts on the walking distance of parking users after parking lots consolidated were analyzed. As a result, it was found that combined plural parking lots can reduce the impacts on the walking distance of the parking users in consideration of the situation of the utilization of parking users of each parking lot.
