Outline of Final Research Achievements

The purpose of this study is to evaluate the effect of reducing the automobile speed on the residential roads several years after it was improved for traffic safety. In order to collect the data used for the analysis, we conducted a traffic survey and a questionnaire survey for residents in areas where traffic safety measures were carried out. Using the data obtained from these surveys, we clarified the actual automobile speed on roads where traffic safety measures were carried out and the residents' evaluation of it. In addition, the traffic safety measures and road structure that affect the automobile speed and the residents' consciousness were clarified.
