Isochrones change speed of walking and cycling from default

I am currently using ORS tools on QGIS 3.16.

Is there any way to change the “default” gait speeds for walking and cycling? I believe 5km/hr and 18km/hr seem quite quick so I would like to know if this can be reduced. Also, could you explain the the reason for these default speeds?


speed calculation can be found in our backend documentation. I’m afraid you can’t reduce it short of changing the code in the backend and running your own instance of the openrouteservice.

For walking, changing the travel speed won’t change any routes that do not include ways with a SAC-scale, it’ll only change the time. This sort of adjustment can be manually calculated as well.

Best regards
