This paper uses Logit models to estimate value of time of car drivers' route choice with evidence from the Stockholm congestion charging trial. Two sets of models are estimated respectively, one is for trips whose purposes are working or running business, the other is for trips who purpose are other activities. In addition, there are two stages of model estimation. At first, the model only includes traffic characteristic variables to differentiate among trips, which includes travel time, travel distance, and congestion tolls. Thus values of time estimated are 176 SEK/h, and 184 SEK/h for working trips and other trips. Further on, socio-economic variables are also involved, along with traffic characteristic variables, in the model to differentiate among both individuals and trips. Significant socio-economic variables include household income, age, gender, access to workplace vehicles, working flexibility and so on. Results of average aggregated value of time are almost the same with the results in basic models, which is reasonable since it’s the same dataset. However, the later model shows more variation in terms of individuals.
