Constraints on capital investment in new road infrastructure and changing community demands are continuing to influence transport planning methods for resolving congestion problems. Conventional methods that aim to improve the supply of the road network are gradually yielding to techniques which optimise existing infrastructure through methods of improved management and planning. Transport demand models provide planners with a useful tool to assist in their decision making process, but traditionally they have lacked the ability to analyse the influence of Travel Demand Management (TDM) strategies. A suite of models that can perform accurate network modelling procedures with the ability to analyse a wide range of TDM measures is required. This paper will discuss techniques that are being developed as part of a TDM modelling suite and in particular, concentrate upon the decision-making characteristics of the traveller associated with modal and route choice.
