A Message-Based Framework for Real-World Mobility Simulations

Abstract: There is considerable interest in the simulation of systems where humans move around, for example for traffic or pedestrian simulations. Any such simulation consists of two layers: the simulation of the "physical" system, which includes effects such as interaction with other agents or the environment; and the simulation of the "mental" layer, which generates strategies of the agents. The traditional way to couple the modules is to use files. The disadvantage of that approach is twofold: The computational perfo… Show more

“…However, only systems with a reduced number of decision-making entities have been represented in terms of intelligent transportation systems vol. to larger data sets (Balmer et al, 2003;Gloor et al, 2004). Thus, a coupling of both behaviors within the layered architecture we have proposed could be the basis for profiting from the qualities of the reactive and the cognitive approaches.…”

“…The team had, when it started with the Java-based MATSim (cf. 46.2.1.4), considerable experience in parallel computing (Nagel and Schleicher, 1994;Rickert and Nagel, 2001;Nagel and Rickert, 2001;Cetin et al, 2003) as well as with more general message-based approaches (Gloor and Nagel, 2005) that resemble today's Protocol Bu ers (Google Developers, 2015). However, the move to Java (see Section 46.2.1.4), a decision for faster conceptual progress and reduced maintenance e ort, also had the consequence that the MPI (Message Passing Interface) approach to parallel computing could no longer be used and was thus given up.…”
