In this research, we analyzed influence of winter weather condition, especially snowfall, on value of travel time. There are two ways to estimate value of travel time: income approach and preference approach. Income approach is usually used for cost-benefit analysis for road construction. However, we adopted preference approach since distress and physical fatigue due to traffic congestion during snowfall may have influence on value of travel time. Specifically, travel history data from ETC 2.0 probe information and route choice data from a questionnaire survey were used to estimate value of travel time. As a result, we found that value of travel time in winter season was significantly higher than that in non-winter season using either travel history data or route choice data. In addition, we confirmed that in winter value of travel time tended to be high even when there was no snowfall. There was a similar tendency for value of time reliability.
