DJUTILS - Delft Java Utilities  


DJUTILS is a set of Java classes that are used as generic classes by other TU Delft projects such as DSOL, OpenTrafficSim, Sim0MQ, GSCG, and others.


DJUTILS was developed at the Delft University of Technology as part of the Open Traffic Simulator project (started in 2014) and the Delft Simulation Object Library (DSOL) project (started in 2002).

The main authors/contributors of the DJUTILS project are Alexander Verbraeck, Peter Knoppers, and Wouter Schakel.

Maven use

Maven is one of the easiest ways to include DJUTILS in a Java project. The Maven files for DJUTILS reside at When a POM-file is created for the project, the following snippet needs to be included to include DJUTILS:


Of course, the version number (1.00.00 in the above example) needs to be replaced with the version that one wants to include in the project.

Right now, the DJUTILS files are kept on a server at TU Delft, and are not yet made available on Maven Central. Therefore, the repository location has to be specified separately in the Maven POM-file:

    <name>djutils Public Repository</name>


DJUTILS is directly dependent on one package, which can have further dependencies:

If the DJUTILS library is used as a part of a Maven project, all dependencies will be automatically resolved, and the programmer / user does not have to worry about finding the libraries.
