| Outline of Final Research Achievements |
A massive traffic congestion and urban gridlock has been observed in many places of central Tokyo, when the Great East Japan Earthquake occurred on March 11, 2011. Serious traffic congestion generated by the Great East Japan Earthquake, prevented the transportation of emergency vehicle. These are very important issues from the point of view of urban disaster prevention.
In this study, we have developed a map-matching technique to integrate multi observed velocity data in the Japan standard digital road map data. This approach was successful in building a database that can be grasped at a high density extensive and longtime traffic conditions after the earthquake. Furthermore, the gridlock every upbound and downbound traffic lanes were identified. A route choice behavior model was developed using the Navitime probe data after the earthquake.
