The dynamic land use and transport interaction model MARS
• MARS is a dynamic land use and transport interaction model. • MARS works on a rather high spatial aggregation.• MARS includes feedback loops between land use and transport
systems.• MARS includes the relevant regional means of transport.• MARS is deterministic in each iteration but it’s markets are not
necessarily in equilibrium.• MARS is designed to identify best performing land use and transport
strategies.• MARS aims at being as transparent as possible („White box“).

Improvements and changes made in DISTILLATE
• Heavy Rail model incorporated for urban stations in Leeds• Congestion added to the off-peak• Quality factors for bus corridors• Representation of increased parking search time due to parking
capacity• Over crowding on public transport• Add awareness campaigns as a policy instrument• Improve the flight simulator front-end• Link output to the dynamic GIS software Animap

Conclusions
• Several improvements of the MARS model have been made based on the outcome of the DISTILLATE survey.
• The user friendly interface has been improved.• For an improved visualisation of the results MARS was linked to a
dynamic GIS software.• The MARS modelling suite is an easy to set up and easy to use tool
to explore, assess and optimise the outcome of complex land use and transport strategies.
