Abstract
The typical method to couple activity-based demand generation (ABDG) and dynamic traffic assignment (DTA) are time-dependent origin destination matrices. With that coupling method, the individual traveler's information gets lost. Delays at one trip do not affect later trips. It is, however, possible to retain the full agent information from the ABDG by writing out all agents' ?plans?, instead of the OD matrix. A plan is a sequence of activities, connected by trips. Since that information is typically already available inside the ABDG, this is fairly easy to achieve. MATSim takes such plans as input. It iterates between the traffic flow simulation (sometimes called network loading) and the behavioral modules. The currently implemented behavioral modules are route finding, and time adjustment. Activity re-sequencing or activity dropping are conceptually clear but not yet implemented. Such a system will react to a time-dependent toll by possibly re-arranging the complete day; in consequence, it goes far beyond DTA (which just does route adaptation). Our paper will report the status of our current Berlin implementation. The initial plans are taken from an ABDG, originally developed by Kutter; to our knowledge, this is the first time that traveler-based information (and not just OD matrices) is taken from an ABDG and used in a multi-agent simulation. The simulation results are compared against real world traffic counts from about 100 measurement stations. Show more
