Multi-Isochrones

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
  1. Display the supermarkets as thematic data (can be found in the “shop” category).
Thematic Data
  1. Set the routing options as desired (e.g. walking, 5km/h, 10 min travel time, 2 isochrones).
choose isochrone range
  1. Switch to the “Multiple” isochrone calculation mode and select the “Study Area” method, which later lists all results differentiated by districts.
Multi Isochrone
  1. Then select all districts that you want to include in the calculation by clicking on the map.
Select Districts
  1. Click on “Calculate.”
Calculate
  1. 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
  1. Select the desired public transport stops (e.g. bus, tram) in the menu “Filter Thematic Data”.

  2. Set the routing options as desired (e.g. bike, 15km/h, 5 min travel time, 2 isochrones).

  3. Switch to the isochrone calculation mode “Multi” and select the method “District” and select the districts on the map or draw a polygon.

  4. Click on “Calculate”.

  5. 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.
