堀 井 雅 史* Masafumi Horii SYNOPSIS In this paper, the author deals with time headway distribution on roads in snowy cities and make clear the characteristics of time headway distribution. Furthermore, several kinds of probabilistic distributions are applied to these data and x2 test is conducted. In conclusion, any probabilistic distributions are not adopted to these time headway distributions according to the x2 test. However, Peason type III distribution and log-normal distribution are similar to these time headway distributions and these distributions can be applied to the INPUT distribution function of a network simulation model.

SYNOPSIS "Mi chi-No-Eki", HACHI-KITA has been in operation on Route 9 in Muraoka-cho, Hyogo Prefecture, since March 1998.."HACHI-KITA" has two types of snow melting systems using ground heat that is typical of untapped energy. One is a Reservoir Heat Collection System (RHCS) that set water tank in underground, and is used to put on or take off tire chains for a 1120m parking lot. The other is a Bore-hole Heat Exchange System (BHES) used for melting snow on a 310m2 sidewalk. Specially, this paper presents the thermal behavior of the fluid in the water tank and the surrounding ground, as well as the seasonal interaction between them. The snow melting performance of the RHCS was completely satisfactory and this made it possible for people to walk from the parking lot to the "Michi-No-Eki" buildings on a snow-free pavement. The fluid temperature was as high as 19.8•Ž on December 31 and a zone with high ground temperature (17-19•Ž) existed around the tank in winter, even though the ambient ground temperature was only about 15•Ž. From these results, it was confirmed that the effect of the thermal energy storage during summer persisted until the following winter.

SYNOPSIS When estimating snow accumulation on a building roof in a heavy-snowfall district, for structural and architectural planning, it is important to know its volume and drift. The snowdrift on and around buildings is usually investigated by snow wind tunnel tests. However, some of the similarity law has not yet been clarified. Then it is not easy to conduct such tests. To clarify the similarity law of snow wind tunnel tests, it is necessary to investigate the relationship between the wind property and snowdrift. The purpose of this study was to clarify the relationship between snowdrift on a building model and wind flow around it by a field observation. In the observation, two pieces of two-level flat roof building models were installed in the athletic field in Hokkaido, and snowdrift distribution, wind direction, wind velocity and temperature were measured every day for two winters. As the result, the property of the snowdrift patterns by wind direction and wind velocity was investigated.
