It was found that there were statistically significant differences in gap acceptance behavior between changing lane to the left/right. The accelerated failure time(AFT) model, random parameter AFT model, and correlated random parameters with heterogeneity in means AFT model were established. The results show that the third model have the best goodness of fit. There is obvious mean heterogeneity in the gap acceptance models of different lane change directions, and the correlation between random parameters significantly affects the gap acceptance behavior.
