Analysis of experience with formalizing handicapped parking system

Abstract

Saga is the first region in Japan to introduce a formalized handicapped parking permit system (known as the PP system), an identification card system, in order to protect accessibility privileges designed for disabled individuals. This paper describes the analysis methodology that relied on a graphical representation to quantify type of occupants and dwell times of usage of handicap parking spaces.The effectiveness of the PP system and its attributes has been analyzed using two different surveys in this research project. The first investigation was an observational survey that focused on quantifying changes in usage patterns including potential illegal use. The investigation indicates that there is an increase of the usage level of parking space allocated following the implementation of new system as it accompanied a broadening of the definition of eligibility. At certain sites, the allocated handicapped parking spaces were occupied for nearly 60% of the time causing unacceptable level of inconvenience for disabled. The second investigation applied a questionnaire survey to examine perception of users of parking facilities. Results of this survey are consistent with findings of the other survey. Although the introduction of permit system and broadening of the definition of disabilities were done with best intentions, the new system has reduced the availability of parking spaces to wheelchair users.
