Train Simulation

This page describes simulations of trains in SUMO. To build an intermodal simulation scenario with trains, additional steps have to be take in comparison to a plain vehicular simulation.

The simulation of trains is a developing subject and still carries some difficulties. These are discussed below.

Approaches to train modelling

Currently, no exclusive movement model for trains is implemented. Instead the existing models for vehicle movement need to be re-purposed

Problems and workarounds

  • No automatic support for railway crossings: Either traffic lights with cycles, hand-tailored to the train schedule or priority nodes may be used.

Building a network for train simulation

Railways can be imported from OSM. They can also be explicitly specified using the existing vClasses. The node type rail_signal may be used to define signals which implement Automatic Block Signaling.
