THE SAFEST ROUTE (letrajetleplussur.fr), the first navigation tool that puts your safety first.For the first time, the French State has made public in open source all road accident data. Groupama has decided to use them by cross-referencing them with the accident notifications of its 3 million policyholders to create the first service generating the least dangerous route. By using the geolocalisation data of the 700,000 reported accidents and by creating an algorithm allowing one to avoid driving on dangerous roads, without adding too much additional driving time. Thanks to THE SAFEST ROUTE, everyone can easily compare the route that all GPS give, the fastest route with the safest route. And everyone can realise that by slightly modifying his/her daily route, he can significantly reduce the risks of having an accident.When all GPS suggest the fastest or the shortest route, it was time to create a tool that gives you the safest.
