Abstract
We argue that context dependence (CD) affects the temporal change of SP data. To reflect this, we propose a new mode choice (r-RP/SP) model based on relative utility function, which consists of the term of alternative similarity and the term of other context-dependent factors like previous choice results. Throughout an empirical analysis, it is confirmed that, (1) the way of using relative utility to incorporate the influence of the CD is effective, (2) the parameters of relative importance (RI) are variant temporally and affected by the CD, (3) as the number of explanatory variables increases, the parameters of RI fluctuate largely among individuals and over time.
