Simulation studies of road snow melting by dropping hot water were carried out for three representative cities in Japan for the past 23 years. Watching a wheel track, hours for which snow and ice was cleared were calculated under conditions that hot water was dropping during the time from 6.00 to 21.00 at given rate. As a result, it was shown, that the percentage of cleared time to non-cleared time in winter seasons decreases with increasing quantity of dropping hot water and begins to saturate to about 10 % at 12 l/h hot water dropping, which corresponds to 30 vehicles/h at a crossing or a slope.
