A Pilot Program and Future Prospects of PDS (Parking Deposit System) as an Alternative Road Pricing Scheme

摘要

While road pricing (RP) is considered one of the most effective means of traffic demand management (TDM), its poor acceptability has been the greatest impediment to its implementation. The authors propose a “parking deposit system” (PDS) as an alternative road pricing scheme, and the aim of this study is to examine PDS’s superiority focusing primarily on acceptability. On the basis of our research results of PDS, the small scale social experiment was conducted in Nagoya in 2008 to get knowledge of the effect of PDS. This paper describes the following three points. 1) Abstract of PDS and the effectiveness shown in our preceding studies. 2) Description and results of PDS pilot program conducted in Nagoya, 2008. 3) Future prospects of PDS
