We also developedregressionmodels of number of trips considering socio-demographic variables as well as ICT use variables.It turnedout that ICT use variables have statistically significant positive effects ontravel.Furthermore,assumingthat interrelat ions betweenICT and travel exist,structural equationmodels were developed taking them as endogenous variables.The model results strongly suggest that ICT use positively affects travel (indicating complementaryeffects). Key Words: ICT, travel behavior, structural equation modeling, telecommunications
