The purpose of this study is to get a basic finding concerning the effect of improving turn possibility of fire engines in the intersection by the installation of corner cut and deployment of small fire engines in crowded wooden houses district with narrow streets. First, we formulated the condition that the turn of fire engines on the corner is possible in consideration of corner cut. Second, we achieved the above-mentioned purpose through solving the following three problems. [1] Analysis of minimum scale of intersection where turn of fire engines is possible. [2] Simulation concerning installation of corner cut and deployment of small fire engines in an existing crowded wooden houses district with narrow streets. [3] Measurement of error margin when an index concerning minimum scale of intersection is applied to the crowded wooden houses district with narrow streets.
