Waterway Simulation

This page describes simulations of (inland) waterways in SUMO.

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

Approaches to ship modelling

Currently, no exclusive movement model for ships is implemented. Instead the existing models for vehicle movement need to be re-purposed. By setting guiShape="ship", vehicles are drawn in a more appropriate shape.

Problems and workarounds

  • Due to the one-way nature of edges in sumo, ships cannot overtake each other by using the whole width of the waterway. To allow overtaking, multiple lanes have to be defined.
  • Since the right-of-way rules for ships are more complex than those for road vehicles, waterway intersections are set to uncontrolled by default.

Building a network for waterway simulation

Waterways can be imported from OSM by adding the type map osmNetconvertShips.typ.xml. They can also be explicitly specified by setting allow="ship".
