Abstract
In order to solve the traffic congestion problem, it is decided to convert some of the traffic from ordinary road to expressway with discounted toll. A route choice survey was conducted to freight and production companies to collect two different types of data; Revealed Preference (RP) and Stated Preference (SP). Estimation was done in four steps; segmentation model, a route choice model with RP data and a convert model with SP data. Finally, RP and SP data were combined in linear and non-linear models. It is identified that VOT follows a decreasing curve by increasing travel time.
