Abstract
This paper suggests that there is an urgent need for a decision support tool or system which makes suggestions to the transportation planner. The paper outlines a theoretical model which seeks to move non-optimal steady state (traffic, price, green-time) distributions steadily toward locally optimal values taking account of users' responses. The model is a multi-modal equilibrium transportation model with elastic demands. Road prices, prices charged to traverse a route (as with public transport fares) and signal green-times are explicitly included as control variables. The model permits values of these control variables which meet specified transportation targets to be estimated. The paper expresses the central problem as a bilevel optimisation problem and suggests four different approaches to solving the problem.
