| Research Abstract |
The total length of the Japanese expressway networks now exceeds 6,500 km and more than three million vehicles are now using them every day. The expressway networks are one of the most important infrastructures which support Japanese economic, industrial and social activities. However, with the increasing traffic demands, expressway users are now suffering heavy traffic congestion on expressway sections in urban areas as well as on trunk route sections in rural areas. In order to cope with this situation, express highway authorities are urging drivers to make more effective use of the expressway system by informing them of the present travel time of each expressway section for selecting effective route.
In view of this, a computer simulation model called the expressway bottleneck simulation model was modified to simulate long distance traffic on expressways and to evaluate the effectiveness of detour guidance operations.
A series of traffic surveys were conducted on the Tomei and Meishin Expressway covering section about 180km in length from the Toyota interchange to the Kyoto East interchange and the modified simulation model was calibrated based on the data collected during the survey.
A procedure for estimating long distance expressway travel time and selecting an appropriate detour route was developed using the calibrated simulation model.
