Define Local Accessibility Sensitivities for Pedestrians

[Philipp-Otter]

Goal of this issue

Currently, GOAT uses a sensitivity of 300000 for almost all amenities, but since the willingness to walk to a destination is different for different amenities, the goal of this issue is to group the amenities and assign more precise sensitivity parameters.

• 1) Process GOAT 3.0 survey results and fit data to the combined and the modified Gaussian function -> create plots and an overview table
• (optional) Filter respondents

1. Filter if respondents live in cities or not (maybe intersect with the RegioStaR)
   -> detailed analysis of respondents living in cities as 90% live in cities
   -> detailed analysis of respondents living in cities
2. analyze age groups
3. analyze gender

• 2) Group our amenities into four categories:

1. Immediate Surroundings (travel time <= 5 min) e.g. bakery, supermarket
2. Close Surroundings (tt <= 10 min) e.g. post office
3. District-Wide Surroundings (tt <= 20 min) e.g. secondary school
4. Citywide Surroundings (tt > 20 min) e.g. theatre

• 3) compare our results with the publication "Stadt Chemnitz Mobilitätsplan 2040 Standort-Werkzeug"
• 4) define sensitivity parameters for the four categories
• 5) visualize results
• 6) revise categories (especially secondary schools)
• 7) recalculate 15 min Score for Munich
• 8) clean acatech code
• 9) document results in the Miroboard (Heatmap Ideas), so it can be implemented in the future -> link important code snippets from the acatech repo/ our first couple trials
