Custom Models

Currently available for the POST /route endpoint only and up on request. If you are interested - send us a support request.

Examples can be found here. You'll also find a link to a demo server including an editor with the JSON format that will check the syntax of your custom model and mark errors in red. You can press Ctrl+Space or Alt+Enter to retrieve auto-complete suggestions. Pressing Ctrl+Enter will send a routing request for the custom model you entered.

GraphHopper provides an easy-to-use way to customize its route calculations: custom models allow you to modify the default routing behavior by specifying a set of rules in JSON language. A simple example using the profile name of your choice or communicated from our support:

View area-condition.json
"priority": [{
"if": "road_class == MOTORWAY && in_near_cottbus == false",
"multiply_by": 0
"areas": {
"near_cottbus": {
