Starting with version 0.26.0 the mesoscopic model is integrated into the SUMO mainline and there is no need for a separate executable. MESO still refers to a mesoscopic simulation model which uses the same input data as the main SUMO model. 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.

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

The mesoscopic model uses the same input files and generates (almost) the same outputs as SUMO. To use MESO the option --mesosim <BOOL> must be set. Additional options are described at SUMO#Mesoscopic

MESO-GUI

The gui application that was also joinedwith SUMO-GUI. Due to being based on edges rather than lanes, some of the visualization options are different when running mesoscopic models.
