<p>At the Hanshin Great Earthquake, street- blockade happened frequently.This study is a fundamental study to develop the quantitative method for the assessment of urban disaster prevention within a local area road network from the viewpoint of street-blockade by using a percolation model. The analysis for the characteristics of each existing method for the assessment is introduced to clarify the position and objection of this study. Then, the influential indicators of the assessment in urban disaster prevention are extracted in order to apply these indicators into the percolation model. As case studies, by applying this method for evaluation into the districts, the performance in disaster prevention within a local area road network are compared and discussed.</p>
