Not sure what stack exactly they use under the hood, but we have created a sophisticated, very fast but similar algorithm implemented in Java. Bonus: everything is open source: https://github.com/graphhopper/map-matching including web API, routing engine, easy setup (no DB involved), simple demo UI, ... Only disadvantage I see: we currently do not support online map matching but this will surely come. BTW: kalman filters are very similar to our approach (hidden markov model). BTW2: Their FAQ is ridiculous: "Do you have competitors? No..." There are many companies with tracking and also open source products ... |
