A collaboration among Fujisawa city and Univ. of Tokyo and GEO SEARCH discussed effective solutions for prevention of road cave-in. “Development of Cave-in Potential Map in Fujisawa city” is one approach to this study and this is the first attempt to evaluate the regional area based on cavity information. The map serves to assess the possibility of evaluate the road traffic network. The parameters were set by analyzing the cavity information based on the actual condition of cavity occurrence. Evaluation was set to four degrees using the combination of cavity environmental factor.
