In the 1995 Great Hanshin-Awaji Earthquake, the traffic of emergency vehicles like fire engines was often obstructed by collapsed structures, fallen poles/fences, damaged road surfaces, etc. specially in heavily affected regions by the earthquake. We investigated into the influence to road traffic obstacles by attributes of roads and surrounding conditions such as road widths and the ratio of collapsed structures. As the results, following were found. (1) If the ratio of collapsed structures was less than 12.5%, obstruction of road traffic did not occure so much. And, if the width of road was 10m or more, occurence of obstruction of road traffic wa less than 10% even though the ratio of collapsed structures was more than 25%. (2) As the most important factor that seriously affects road traffic condition is collapsed structues, one of the very basic measures for preventing road traffic obstruction should be construction of earthquake-proof houses and buildings.
