The impacts arising from the introduction of parking guidance and information (PGI) systems should be quantified to check whether the goals of these systems are being achieved and to identify if there are any negative impacts being incurred on groups involved in parking. It is also important to investigate driver response to PGI systems since it is not clear what types of drivers are using them and how they are influencing parking choice. This paper describes the application of a number of survey and analysis techniques recently undertaken to estimate the impact of PGI systems in several cities in Japan. Major findings of an interview survey of drivers conducted in Shinjuku are presented. Models relating driver awareness, usage and understanding of PGI systems to various driver and trip characteristics were developed. Both driver awareness and usage were found to be strongly related to trip frequency and origin. An analysis of the type of parking-related information requested by drivers was also undertaken. Summary results of studies evaluating the impacts of PGI systems in Osaka and Utsunomiya are also presented. Overall, it appears that many of the aims of the PGI systems studied are generally being achieved with only moderate awareness and usage levels. These results can be used to suggest appropriate modifications to the design of these and other PGI systems in the future. (a) For the covering entry of this conference, see IRRD abstract 868345.
