Abstract:
Rapid growth of technology and the increase in availability of fast communication means caused transportation planners to pay attention to solutions of demand management with an aproach to information technology. Replacement of traditional shopping with internet shopping can be seen as a suitable solution to reduce traffic and polution. Purpose of this research is to probe teleshopping choice and the frequency of doing that, simultaneously, using copula model as the most common aproach of joint models in recent years. In this research, the binary logit model is used to build the model for teleshopping choice and the order logit model is used to build the frequency model. The data sample is consist of 346 university students born and resident in Tehran. Eventually, after building various copula functions, the Frank copula with a liklihood value of -462/09 and the BIC value of 1064/49 is chosen as the best data fit. The negative dependance parameter with acceptable statistical significance in this copula indicate existance of unobserved factors between the two models and demanding to model teleshopping choice and the frequency of doing that jointly
