| Outline of Final Research Achievements |
The various analyses related to the evaluation of improvement projects in densely built-up wooden residential area were performed using the simulation model, which describes wide-area evacuation at a large earthquake. Firstly, the past improvement projects were evaluated with the difficulty in wide-area evacuation between two time points (1991 and 2006) as an index. Secondly, as an example of the application of the simulation model to considering the specific methods to improve cities, the effects of adding new evacuation routes connecting between two narrow and long streets were verified. Thirdly, the exposure risk with fire-spreading for people and the congestion of streets and evacuation areas were estimated considering people who return home on foot after an earthquake occurs. Fourthly, the effects and risk of rescue activities by local residents were quantified. Lastly, the basic analyses were performed in order to take automobile users at a large earthquake into account.
