Estimation of the Value of Winter Road Information on Mountain Passes

Winter Mountain Pass Guide Experiment has been carried out to improve quality of mobility by providing road information of mountain passes to road users. The effect of winter road information provision on mountain pass is to change drivers' transportation behavior choices, such as changing departure time, canceling the trip and changing the travel route. However, it is a problem if road administrator considers to the future employment as the road project that the framework of cost-benefit evaluation for such a road information provision has not established yet. In this study, a stated preference survey was carried out to the monitors of the Winter Mountain Pass Guide to estimate the value of road information provision for measuring the appropriate scale of the project, and the benefit of the value of road information was experimentally calculated by using the exist evaluation model.
