SUMO is the simulation itself; it is a microscopic, space-continuous, and time-discrete traffic flow simulation.

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 NETGEN, 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


You may use a XML schema definition file for setting up a SUMO configuration: sumoConfiguration.xsd.


Option Description
-c <FILE>

--configuration-file <FILE>

--save-configuration <FILE> Saves current configuration into FILE
--save-template <FILE> Saves a configuration template (empty) into FILE
--save-schema <FILE> Saves the configuration schema into FILE
--save-commented <BOOL> Adds comments to saved template, configuration, or schema; default: false


Option Description
-n <FILE>

--net-file <FILE>

Load road network description from FILE
-r <FILE>

--route-files <FILE>
