The project is now open for external submissions, and we gladely accept patch submissions through the SourceForge patch interface.
We encourage you to read through the following documents if you plan to contribute some code to this project sometime in the future:
Trip Tracker is currently under the Never-Branch policy until it's sufficiently mature. Further documentation on the project development process will be released when it's done.
The project report being delivered to UiS for evaluation is written in Norwegian, but an English translation will be made available in due time. Meanwhile you still have Javadoc and SVN log messages as a sort of documentation in addition to comments in the source code.
