MESO is a mesoscopic simulation model which uses the same input data as SUMO. It computes vehicle movements with queues and runs up to 100 times faster than the microscopic model of SUMO. Additionally, due to using a coarser model for intersections and lane-changing it is more tolerant of network modelling errors than SUMO. MESO is currently not open, but made available for project partners only.

Purpose: Simulates a defined scenario

System: portable (Linux/Windows is tested); runs on command line

Input (mandatory):

A) a road network as generated via NETCONVERT or NETGENERATE, see Building Networks

B) a set of routes (as generated by DUAROUTER, JTRROUTER, DFROUTER, or ACTIVITYGEN, see also Definition of Vehicles, Vehicle Types, and Routes)

Input (optional): Additional definitions of traffic lights, variable speed signs, output detectors etc.

Output: SUMO allows to generate a wide set of outputs; visualization is done using SUMO-GUI

Programming Language: C++

Usage Description

MESO-GUI

The MESO-simulation comes with a gui application that works very similar to SUMO-GUI. Due to being based on edges rather than lanes, some of the visualization options are different.
