ABM & Traffic: History
• 1950er– James Lighthill, Univ. of Manchester
Traffic flow modeled as fluid– General Motors Research Group
modeled automobiles as individual units
• 1970er– Rainer Wiedemann, Univ. of Karlsruhe
explored complex psychological behavior

ABM & Traffic: History
• 1990er– Kai Nagel and Michael Schreckenberg
Simple psychological rules:• The drivers have a preferred speed• The drivers keep a safe distance• There are random disturbances

Microscopic models2. Generation
• Microscopic, but with activity-based demand
• IlumassUnis Bamberg, Dortmund, Köln & Wuppertal, RWTH Aachen, DLR, Bundesministerium für Bildung & Forschung, Deutschland
• TransimsLos Alamos National Lab (UC) & IBM, USA

Learning models
• The agents learn from their experience and adapt their travel plans
• BAB-NRWUni Duisburg/Essen, Ministerium fürVerkehr, Energie und Landesplanungdes Landes NRW, LandesbetriebStraßen NRW, Germany

Example: UrbanSim
• UrbanSim is a simulation model for integrated planning and analysis
• Developed at the Univ. of Washington, Seattle
• Features decision-making by households, businesses, developers and governments
