Sumo
SUMO is a microscopic traffic simulation suite designed to model the movement of individual vehicles and pedestrians across large-scale urban road networks. It functions as a multimodal transport simulator that integrates cars, pedestrians, bicycles, railways, and waterways within a single environment, supported by tools for road network generation and traffic demand modeling.
The project distinguishes itself through specialized toolsets for environmental impact analysis, which calculate vehicle emissions and energy consumption for electric and hybrid fleets. It provides comprehensive capabilities for modeling autonomous vehicles and automated driving systems, as well as a road network generator that imports industry-standard spatial data and XML definitions.
The system covers a broad range of operational areas including traffic infrastructure management for signal schedules, traffic flow calibration using real-world sensor data, and the generation of vehicle flow profiles via origin-destination matrices. It also supports the simulation of traffic incidents and the creation of custom sensing devices to monitor or influence traffic flow.
The software utilizes structured XML files for scenario definition and offers an external interface for real-time simulation control.
