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.

• High performance: C++ implementation using Rtree, optimized routing, parallel computing (OpenMP).
• Python API: jupyter-notebook and web demo
• Scalibility: millions of GPS points and millions of road edges.
• Multiple data format:
  • Road network in OpenStreetMap 🎉 or ESRI shapefile and Geopackage.
  • 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).

We encourage contribution with feature request, bug report or developping new map matching algorithms using the framework.

• Interactive web demo

• Command line examples
• Jupyter-notebook

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.
