Mezzo - Mesoscopic Traffic Simulator

Mezzo is a discrete-event  traffic simulation model that simulates road traffic on the level of individual vehicles, but with an aggregated behaviour on links. The model is especially designed to simulate large networks and can be used in combination with a microscopic simulator to work as a hybrid model, where a specific area of interest is simulated in microscopic detail (all vehicle movements and driver decisions are simulated explicitly) while the surrounding network is simulated att mesoscopic level (aggregated behaviour ). Mezzo is free and Open Source software (GPLv3)  and can be downloaded and used by anyone. Any modification or adaptation of the source code is allowed, but has to result in a (new) GPL open source software, and keep the original license and copyright notice. We maintain a development blog where all recent and coming developments are discussed.
