FMM is an open source map matching framework in C++ and Python. It solves the problem of matching noisy GPS data to a road network. The design considers maximizing performance, scalability and functionality.
Check the online demo.
- High performance: C++ implementation using Rtree, optimized routing, parallel computing (OpenMP).
- Python API: jupyter-notebook and web app
- Scalibility: millions of GPS points and millions of road edges.
- Multiple data format:
- Road network in OpenStreetMap or ESRI shapefile.
- GPS data in Point CSV, Trajectory CSV and Trajectory Shapefile (more details).
- Detailed matching information: traversed path, geometry, individual matched edges, GPS error, etc. More information at here.
- Multiple algorithms: FMM (for small and middle scale network) and STMatch (for large scale road network)
- Platform support: Unix (ubuntu) , Mac and Windows(cygwin environment).
- Hexagon match: 🎉 Match to the uber's h3 Hexagonal Hierarchical Geospatial Indexing System. Check the demo.
We encourage contribution with feature request, bug report or developping new map matching algorithms using the framework.

FMM originates from an implementation of this paper Fast map matching, an algorithm integrating hidden Markov model with precomputation. A post-print version of the paper can be downloaded at link. Substaintial new features have been added compared with the original paper.
