Isochrones

Description of the feature

Isochrones are isolines connecting all points that can be reached from a specific starting point within a certain time interval. GOAT allows the calculation of isochrones that take factors such as speed, infrastructure network, and traveling time into account. This can be adjusted automatically by choosing between the modes “Walking”, “Bike” or “Pedelec”. Isochrones can be used as an indicator of accessibility in one specific location.

Possible use cases (planning questions)

  • How many supermarkets can be reached from a certain point in a 10-minute walk?
  • How many people can access a public transport station within 5 minutes of cycling?
