I have developed MapReduce algorithm for traffic assignment for the OpenTransportNet project. And I’m providing data support for the OpenTransportMap (e.g import route data from OSM). During this Hackathon I can help you with Routing algorithms, Spark or PostGIS and with more (geo) technologies.
If you are interested in these technologies you can attend this Hackathon and develop your dream project.
