Effects Analysis of Zone 30 Based on Recognition, Age and Accident Experience

This study was made to answer the question that the recognition for Zone 30 is necessary for the drivers to drive cars safer or not? We conducted some surveys to analyze influences of the recognition for Zone 30. As the target district, Motoshiro district in Toyota City in Japan, where Zone 30 had been put into implementation, was chosen. As the results, there are statistically significant differences between the recognition people and the rest regarding the maximum driving speed. It is known that the maximum speed when driving in the Zone 30 district is reduced more when the drivers recognized the Zone 30 implementation. Then, the analyses were applied for the comparison among the elderly people and the others. The elderly people tend to make higher evaluation for the Zone 30 measures. Moreover, further analysis shew that the Zone 30 related measures have higher potential for the people who experienced traffic accidents than that having no accident experience.
