In this research, as one of the researches to promote various measures for traffic facilitation in winter, we analyzed influence of winter weather condition, especially snowfall, on value of travel time and calculated travel time-saving benefits. In this research, we adopted preference approach since distress and physical fatigue due to traffic congestion during snowfall may have influence on value of travel time. The case study was conducted in Niigata Prefecture, where most of the prefecture is designated as a special heavy snowfall area. The results confirm that the value of travel time is significantly higher in the winter period than in the non-winter period. The value of travel time in winter was used to calculate the travel time-saving benefits based on the cost-benefit analysis manual. The results show that even if the reduction in traffic volume during the winter period is subtracted, the travel time-saving benefits is greater when using the value of travel time in winter.
