Abstract
This paper aims to discuss the relations of monitoring and modelling methods of trip maker's route choice behaviour in a transport network, and to show possible directions of model development of route choice. Previous monitoring methods based on questionnaire are not sufficient for detailed analysis of travel behaviour in space/time dimensions. A new observation method using mobile communication system is possible to trace the movement of individual route choice behaviour, The results of behavioural analysis using detailed route choice data could be applied for improving route choice models employed in network flow models such as User Equilibrium.
