1️⃣ Age Group Selection

Choose which demographic group to analyze:

• Children: 4.0 km/h, wtw-distance: 860 m, 3.98 J/kg/m, 30 kg
• Young Adults: 4.9 km/h, wtw-distance: 935 m, 3.4 J/kg/m, 74 kg
• Adults: 4.8 km/h, wtw-distance: 859 m, 3.4 J/kg/m, 78 kg

• MR (Mobility Restricted): 3.2 km/h, wtw-distance: 500 m, 5.43 J/kg/m, 70 kg

2️⃣ Metrics to Calculate

• Travel Time: (Always included) Time to walk to each POI (isochrones only)
• Energy Expenditure: Calories burned based on age group parameters
• POI Weighted Time: Time adjusted by POI importance
• Willingness-to-Walk: Distance age-group people are willing to walk
  • Adjust the max distance slider to set preferences (isochrones)
  • Default values vary by age group (heatmap)

3️⃣ Filter POI Categories (Isochrone only)

Select which types of places to include:

• Restaurant & Bar: Dining and nightlife
• Food Supplies: Supermarkets, bakeries
• Healthcare: Hospitals, doctors, pharmacies
• Education: Schools, universities, libraries
• Outdoor & Sports: Bench, Parks, gyms, sports facilities

• Services: all kind of services
• Transport: All public transport stations, Taxi stands

Uncheck categories to focus on specific types of POIs.

📊 View Mode (Heatmap only)

• By Hexagon: See individual hexagon cells with color gradients
• By District: View district-level aggregated data

Chart Types

• Line Chart: Shows numerical (number of hexagons) distribution of values for all age groups.
• Box Plot: Shows value distribution of all age groups.

Available Metrics

• POI Weighted Time: Average walking time to POIs, weighted by importance. Lower is better.
• Energy Expenditure: Average calories burned walking to POIs. Lower values mean less effort required.
• WTW Score: Willingness-to-Walk score. THe higher, the more POI are reachable in fixed distance.
