Route Choice Models and Traffic Assignment

Route choice models are critical as they provides the final output of traffic models and thus give input to impact analyses on link-level, e.g. local environmental and safety considerations. As such, it is mostly the results of route choice models that are directly addressed by the political decision maker.
A major task in the project has been to develop route choice models which consider delays in intersections. In addition the traditional Stochastic User Equilibrium Model has been extended to consider differences in road users utility functions. These two theoretical developments has proven successfully in several applied projects. Sub-projects have carried out together with Tetraplan and Hague Consulting. Issues concerning passenger's route choices in public transport, multiple-class assignment and methods to enumerate cost from assignment models are now being developed.
