SUMO (Simulation of Urban MObility) is a free, open-source, highly portable, and microscopic traffic simulation suite developed by the German Aerospace Center (DLR). It is widely used by researchers, urban planners, and engineers to build realistic virtual transportation environments and test mobility solutions. Core Characteristics of SUMO
Microscopic Simulation: Every individual vehicle, passenger, and pedestrian is modeled explicitly with its own specific speed, acceleration profile, and unique route.
Multimodal Modeling: It handles intermodal traffic seamlessly, including cars, trucks, buses, trains, bicycles, and pedestrians.
No Artificial Limitations: The software uses portable C++ libraries allowing you to model an unlimited network size and an infinite number of vehicles, bounded only by your computer’s hardware. The 4-Step Simulation Pipeline
To run a basic simulation in SUMO, you must go through a structured data pipeline using its modular application suite:
[1. Build Network] 2. Generate Traffic (randomTrips)/ / [3. Route Optimization (duarouter)] | [4. Execute Simulation (sumo-gui)] 1. Generating the Road Network
Every simulation requires a map network file (.net.xml). You can create this in two primary ways: Traffic Modeling with SUMO: a Tutorial – arXiv
