SUMO
Contents |
From 30.000 feet
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 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++
