As our Directions API currently does not include traffic data we still show you that it is possible to integrate traffic data into GraphHopper if you have the data. A few days ago I’ve blogged about a simple way to feed GraphHopper with generic traffic data from elsewhere. Today we look into one specific example: […]

Update: there is a new blog post which shows integration of real time traffic info into GraphHopper from a real world example, including a simple UI based on HTML5 canvas. There are several companies having its own traffic data e.g. those companies having an own fleet or fetching it from an external source. Often on […]
