In this paper, the method of survey of snow pile on sidewalk and the result in winter of 1994 in Fukui city are reported. In this winter, the maximum depth of snow was 66 cm high and it was less than normal value 76 cm. But there is a small study on security for pedestrian in snow season, so this paper must be very usefull.
After snowfall, usually it is found that snow piles are formed on roadside or sidewalk by snow removal from roadway. Sometimes mass of snow is carried there from parking area or front of house.
At first, the model of calculation of snow piling on sidewalk by removal work is presented and we discuss how pedestrian area to be kept secure. The state of pedestrian area is classfied into three levels by means of appearance of snow pile. Especially it is important for planning of snow melting facility or snow removal work on sidewalk to make clear how each level go on untill snow melt away.
We made surveies of two places of prefectural road in Fukui city, and snow pile was divided into seven types by means of piling progress. In one area of Fukui city, we investigated relations between security for pedestrian and appearance of snow pile. And it was confirmed that snow pile had affected influence on pedestrian more long time than natural snow cover.
