Abstract: There is significant heterogeneity among travelers'evaluation on in-vehicle congestion. The impact of in- vehicle congestion was studied with the random parameters Logit model. In view of the impact of the latent psycho- logical factor on travelers'mode choice,travelers'demand of comfort was taken into account . The results show that the random parameters Logit model fit the data much better than the traditional discrete choice model. From the re- sult,it can be concluded that,the parameters of price and in-vehicle time are non-random. However,the parame- ter of in-vehicle congestion is random,and it is affected by travelers'demand of comfort when traveling and in-vehi- cle time. The impact of in-vehicle congestion increases as travelers' demand of comfort increases,and decreases when in-vehicle time increases.

Key words: congestion degree, travel choice behavior, travel comfort, random parameters Logit model
