LUTDMM: AN OPERATIONAL PROTOTYPE OF A MICROSIMULATION TRAVEL DEMAND SYSTEM FOR TRANSPORT-LAND USE STUDIES

This paper describes the development of an integrated transport and land use microsimulation model system, the Land Use-Travel Demand Microsimulation Model (LUTDMM), which is based on the activity-based approach for analysing travel behaviour. LUTDMM is designed for use in multimodal urban transport corridors, with the initial study area focusing on the north-west metropolitan corridor of Adelaide. The primary objective of the model is to provide estimates of the likely usage of different travel modes, with an emphasis on features that can determine the likelihood of people using public transport and non-motorised modes, in particular where the incorporation of alternative land use patterns supportive of such modes is envisaged. The model system consists of four sub-models - socio-demographic, synthetic population generator, activity-travel simulator, and network. The sub-models are loosely connected with each other and can be used independently. The paper reports the initial results from the model testing, as well as a small example of model application, which clearly demonstrates the capability and flexibility of the approach.
