From these results, one can observe the impact of using the inappropriate model (independent model without accounting for endogeneity) and the hypothetical or potential effect of ITC on the studied travel outcomes. Potential effect of mobile phone access: Examining the impact of mobile phone access on activity space and GHG outcomes, the results clearly illustrate that access to mobile phone associates with an increased activity space for individuals. In fact, a 100% rate of mobile phone access would be accompanied by an increase in activity space by 12.3% (TTNT). The potential implications for GHG emissions are more important. In this model, we see that a hypothetical saturation of mobile phone access would be associated with an increase of 29.5% in GHG emissions. With the increasing take-up of mobile phone services in Canada, this could be cause for concern. The results also clearly highlight the difference between the independent model and the copula model. It is also important to mention that the failure to take endogeniety into account would change the sign on the results.
