INTERACTION BETWEEN LAND-USE/DISTRIBUTION AND ASSIGNMENT

This paper reports on a study to investigate the feasibility of determining a synthetic equilibrium between the demand for travel and level of service provided by a network. The method adopted is an iterative algorithm that involves the feedback of a travel cost matrix, obtained at the end of a traffic assignment phase, to a land-use/distribution phase. TRANSTEP, a land-use/distribution model, is used for modelling travel demand and ARRBTRAFIC, an equilibrium assignment model, is used for estimating travel delays between each pair of origin-destination zones. The algorithm is tested using three different initial conditions. The results indicate the existence of an equilibrium region after four to five iterations. Further iterations lead to oscillations with an amplitude of five to ten per cent around the equilibrium. These interim results demonstrate the effect of congestion costs on demand models such as TRANSTEP, and identify areas suitable for the refinement of both TRANSTEP and ARRBTRAFIC. (Author/TRRL)
