It is and was a special year, and we almost forgot to send out a newsletter, even though we developed many new features. You can subscribe to the low frequent newsletter when you register here. The biggest change is that all our routing-related APIs like the Matrix API, Isochrone API, Routing API and Route Optimization […]
Today we are releasing version 2.0 of the open source GraphHopper routing engine. GraphHopper calculates optimal routes in road networks, for example taken from OpenStreetMap, for many different vehicle types and finds the ideal itinerary when using public transit. It is released under the Apache License 2.0 and you can easily try its road routing […]
Suppose you have 50 deliveries and you hire four drivers to make those deliveries. Each driver is either paid for a certain number of hours or is paid for a certain number of jobs.

GraphHopper’s Route Optimization API is a powerful tool that lets you easily calculate efficient round tours like this for a selection […]
Introduction A few years ago, we wrote a tutorial to show you how to model a traveling salesman problem with a week-planning horizon. Since then we have been improving our API a lot and I would like to show you how easy it is now to model this with driver shifts. For example, suppose you […]
Today we are proud to announce another big improvement of GraphHopper’s Directions API: We’ve added turn restriction support to our routing solutions! Turn costs and turn restrictions, defined The time it takes to go from one place to another depends on how far we need to go (distance), and how fast we travel that distance […]
