Imagine you are in a foreign city and need to visit fifty different locations that day. Which way should you go? Or let alone which is the best order to visit all these places? GraphHopper’s Route Optimization API is a powerful tool that lets you easily calculate efficient round tours like this for a selection […]

The Routing API has supported path details for 2 years, but had some limitations. E.g. the details like cycleway, or bridleway where missing, which is now returned instead of a generic “other” value. Also path details are now supported for the TomTom add-on. Before: Afterwards: If you want to see this feature in action on […]

Using publicly available map data from OpenStreetMap it can calculate the optimal route for a given source-target pair for many different vehicles and flexible optimization criteria. However, such route calculations become considerably more […]

After over a year of work on the edge-based routing for the speed mode (Contraction Hierarchy=CH) it is now possible to support turn costs for […]
