Transit routing server app written in C++ using the Connection Scan Algorithm including flexible parameters.
With random origin and destination (multiple accessible stops at origin and destination): ~150 ms for access and egress footpaths calculation, ~8 ms for CSA two-way calculation (tested with montreal area GTFS data including all urban and suburban transit agencies, with transfer footpaths between stops of 10 minutes walking or less) on a MacPro 2013 with single thread used (you can start multiple servers and execute parallel requests).
Open Source Routing Machine (OSRM) (must be installed separately, see install and usage instructions in OSRM Wiki) use -DBOOST_ROOT option to choose boost path if not default (ex: /usr/lib or /usr/local/lib)
