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

Options

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

Configuration

Option Default Value Description
-c <FILE>

--configuration-file <FILE>

Loads the named config on startup
--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> false Adds comments to saved template, configuration, or schema

Input

Option Default Value Description
-n <FILE>

--net-file <FILE>

Load road network description from FILE
-r <FILE>

--route-files <FILE>

Load routes descriptions from FILE(s)
-a <FILE>

--additional-files <FILE>

Load further descriptions from FILE(s)
-w <FILE>

--weight-files <FILE>

Load edge/lane weights for online rerouting from FILE
-x <STRING>

--weight-attribute <STRING>

traveltime Name of the xml attribute which gives the edge weight

Output

Option Default Value Description
--netstate-dump <FILE> Save complete network states into FILE
--netstate-dump.empty-edges <BOOL> false Write also empty edges completely when dumping
--summary-output <FILE> Save aggregated vehicle departure info into FILE
--tripinfo-output <FILE> Save single vehicle trip info into FILE
--vehroute-output <FILE> Save single vehicle route info into FILE
--vehroute-output.exit-times <BOOL> false Write the exit times for all edges
--vehroute-output.last-route <BOOL> false Write the last route only
--vehroute-output.sorted <BOOL> false Sorts the output by departure time

Time

Option Default Value Description
-b <TIME>

--begin <TIME>

0 Defines the begin time; The simulation starts at this time
-e <TIME>

--end <TIME>

-1 Defines the end time; The simulation ends at this time
--step-length <TIME> 1 Defines the step duration

Processing

Option Default Value Description
-s <INT>

--route-steps <INT>

200 Load routes for the next INT seconds ahead
--no-internal-links <BOOL> false Disable (junction) internal links
--ignore-accidents <BOOL> false Do not check whether accidents occure more deeply
--ignore-route-errors <BOOL> false Do not check whether routes are connected
--max-num-vehicles <INT> -1 Quit simulation if this number of vehicles is exceeded
--incremental-dua-step <INT> Perform the simulation as a step in incremental DUA
--incremental-dua-base <INT> 10 Base value for incremental DUA
--scale <FLOAT> Scale demand by the given factor (0..1)
--time-to-teleport <TIME> 300 Specify how long a vehicle may wait until being teleported, defaults to 300, non-positive values disable teleporting
--max-depart-delay <TIME> -1 How long vehicles wait for departure before being skipped, defaults to -1 which means vehicles are never skipped
--sloppy-insert <BOOL> false Whether insertion on an edge shall not be repeated in same step once failed.
--lanechange.allow-swap <BOOL> false Whether blocking vehicles trying to change lanes may be swapped.
