Application Overview
SUMO was started as an open source project in year 2000. The idea was to support the traffic research community with a common platform to test and compare models of vehicle behaviour, traffic light optimisation, routing etc.
Package Contents
The package contains the following applications:
- command-line simulation (SUMO)
- simulation with a graphical user interface (GUI)
- network builder/converter (NETCONVERT)
- network builder/generator (NETGEN)
- OD-matrix to trip definitions converter (OD2TRIPS)
- a router using a dynamic user assignement approach (DUA-ROUTER)
- a router using junction ratio descriptions (JTR-ROUTER)
Used Models
The car movement model is a microscopic, space-continuous and time-discrete car-following model developed by Stefan Krauß ([Krauss1998_1], [Krauss1998_2]).
The traffic assignment is made using the DUA-approach by Christian Gawron ([Gawron1998_1]).
Design Principles
From the begin on the following design principles were followed: the software has to be as portable and as fast as possible. The first is reached by usage of the standard C++ - functions only, the second by using Krauß' fast car-following model for the computation of vehicle movements.
Other limitations such as the memory usage are not considered that much, although a simulation of large areas shall be possible on normal desktop computers.
Current Version
The current version is 0.8.0.2.
