Description of the feature
GOAT enables the calculation of multi-isochrones, which show how many residents from a certain neighbourhood have access to a facility (e.g. supermarket, kindergarten, public transport stop) in a certain travel time. This is particularly useful for comparing different neighborhoods in terms of accessibility to identify potential differences.
Possible use cases (planning questions)
- How well are the supermarkets currently distributed over the city? In which districts do you have accessibility deficits?
- How many inhabitants can reach a public transport stop by bicycle in a given travel time?
Step-by-step tutorial for an exemplary planning task
1 Accessibility to supermarkets
1.1 Planning question
How well are the supermarkets currently distributed over the city? In which districts do you have accessibility deficits?
1.2 Step-by-Step guide
- Display the supermarkets as thematic data (can be found in the “shop” category).

- Set the routing options as desired (e.g. walking, 5km/h, 10 min travel time, 2 isochrones).

- Switch to the “Multiple” isochrone calculation mode and select the “Study Area” method, which later lists all results differentiated by districts.

- Then select all districts that you want to include in the calculation by clicking on the map.

- Click on “Calculate.”

- The resulting multi-isochrones shows the catchment areas of the supermarkets (here for the mode “pedestrian” with 5 minutes catchment area and 10 minutes catchment area). The corresponding table shows, sorted by district, how many people out of the total population can reach a supermarket in 5 or 10 minutes walking distance.
2 Accessibility to public transport
1.1 Planning question
How many inhabitants can reach a public transport stop by bicycle in a given travel time?
1.2 Step-by-Step guide
Select the desired public transport stops (e.g. bus, tram) in the menu “Filter Thematic Data”.
Set the routing options as desired (e.g. bike, 15km/h, 5 min travel time, 2 isochrones).
Switch to the isochrone calculation mode “Multi” and select the method “District” and select the districts on the map or draw a polygon.
Click on “Calculate”.
The resulting multi-isochrones show you the catchment areas of the public transport stops (here for the mode “bicycle” with 5 minutes catchment area and 2.5 minutes catchment area). The corresponding table shows, sorted by district, how many people of the total population can reach a public transport stop in 5 or 2.5 minutes by bike.
