Abstract

This study aims to evaluate measures against the Urban Heat Island (UHI) from the viewpoint of artificial exhaust heat of road traffic using Geographic Information Systems (GIS) in the Tokyo 23-Ward Area where the degree of UHI is tremendously strong. We created a GIS database that reflects road traffic conditions and calculated the volume of artificial exhaust heat of road traffic to evaluate measures against the UHI. The findings of this study can be summarized in the following three points. (1) The volume of artificial exhaust heat of moving objects is more than that of stationary objects. On intra-highways and beltways where traffic density and speed are high, the volume of artificial exhaust heat of moving objects is particularly high. By vehicle type, the volume of artificial exhaust heat of passenger cars and small freight cars is especially high, and it is highest in the daytime on weekdays. (2) Although there are differences in degree, the measures regarding moving objects such as exhaust heat suppression by fuel burning, facilitation of traffic flow by road development for bicycles and walkers, beltway development, and enhancement of traffic signal limitation are effective in reducing the volume of artificial exhaust heat. However, roads with a high reduction ratio in the volume of artificial exhaust heat differ according to the measures taken. (3) Measures regarding stationary objects such as special pavements and promotion of high energy consumption efficiency in equipment result in high reduction ratios (about 30%) in the volume of artificial exhaust heat and can be widely effective.
