Bugfix (2016-10-21): We fixed a bug in Plexe-SUMO that might make vehicles misbehave for a platoon size larger than 8. If you are experiencing troubles, please update your Plexe-SUMO source from github, plexe-dev branch (go to github).
macOS Sierra (2016-10-20): If you are having problems building Plexe-SUMO on macOS Sierra, please see building notes for macOS here.
Little documentation update (2016-09-07): The documentation section now lists the Plexe-Veins source files together with their purpose. In addition the API section lists the Plexe API developed for specific platooning purposes. The full source code documentation is still in preparation, but this should help you getting started.

Please consider using development version (2015-09-08): Plexe-1.1 is still based on old versions of Veins and SUMO. Several bugs have been fixed on newer versions of the software, so please consider using the development version of Plexe. See this page for more info.
Realistic engine model (2015-02-24): We are now working together with people at the University of Naples on a detailed engine model for Plexe. It is very promising, but it still need some testing. Stay tuned!
