| Outline of Final Research Achievements |
Many kinds of surrogate indicators for evaluating the safety of traffic by flow observations have been proposed, which considers headway time and vehicle deceleration behaviors, but not vehicle weight. In this study, a new index called "Minimum Safe Time Gap" is proposed for the safety evaluation taking account into the deference of deceleration performance due to the vehicle weight, and is verified the validity based on the long-term observation data. In addition, the social effect from enforcement and vehicle detour possibility of overloaded vehicles is estimated. However the development of portable weigh-in-motion device which was originally planned, needs improvement in measurement accuracy and modify of mounting system.
