OTS - Open Traffic Simulation

OpenTrafficSim aims to bring traffic simulation to a new level:

  • OpenTrafficSim combines micro-simulation, macro-simulation and meta-simulation in a single environment.
  • OpenTrafficSim combines all traffic modes (private cars, buses, trains, bicycles, pedestrians, airlines, etc.) in a single simulator.
  • OpenTrafficSim uses DJUNITS for a strongly typed unit system for values. A length scalar cannot be added to a time scalar; if length is divided by time, a speed variable results. This is all checked at compile time rather than at run time.
  • OpenTrafficSim uses DSOL as the underlying, powerful simulation platform. DSOL takes care of time advance mechanisms, discrete-event and continuous simulation, random streams, probability distribution functions, experiment management, etc..

OTS-ROAD is the Open Traffic Simulation module for road-based transport.

  • OTS-ROAD is built on top of the OTS-CORE module that takes care of network structure, general movement of objects, storage of routes, use of the DSOL simulator, etc..
  • OTS-ROAD models road infrastructure (link-based or lane-based).
  • OTS-ROAD includes several models for headway (IDM, IDM+) and lane changing.
  • OTS-ROAD includes more advanced behavioral models such as LMRS.
  • OTS-ROAD has models for perception of the environment by GTUs (General travel Units such as cars).
  • OTS-ROAD models traffic lights.
  • OTS-ROAD has functions to model O/D matrices.
  • OTS-ROAD includes different types of statistics and several types of graphs for reporting.

OpenTrafficSim has an open source BSD 3-clause license.

  • Third party components used in OpenTrafficSim can not have a license that is more restrictive than BSD, Apache, MIT, LGPL, Eclipse.
  • OpenTrafficSim can be incorporated in part or in full in other products for any use (educational, commercial, whatever).
  • OpenTrafficSim may be extended, evolved by anyone into anything else for any purpose.
