Accessible population by public transport in the Rhenish region

The dataset contains the number of people in North Rhine-Westphalia who can be reached within an hour by public transport. It includes a complete day for each inhabited 100 m grid cell of the Rheinische Revier.

The underlying methodology is a ‘cumulative opportunity’ accessibility calculated with the best possible connection that can be started in the given hour. This means that for each populated 100 m grid cell, all connections to the other grid cells are calculated for each minute in a maximum of 60 minutes. For each hour, all persons are then summed up in the reachable cells.

Nomenclature of field naming: OV_01: Accessible population by public transport with start of travel between 01:00 and 01:59. The addition "_01" represents the time disk.

The calculation was carried out with R5R. The following settings were selected
• access to public transport is on foot
• the reasonable distance to the stop has been limited to 1000 m
• a maximum of 3 transfer processes are possible
• Start and finish points are the midpoints of the 100m grid cells.
• The accessibility was calculated for 18.01.2023 (restrictions due to temporary failures or blockages cannot be excluded).

The following data sources were used to create the dataset:
• Association for the Promotion of End-to-End Electronic Passenger Information (DELFI) (2023): Germany-wide target timetable data (GTFS)
• Federal Office of Cartography and Geodesy (BKG): Geographical grids for Germany in Lambert projection (GeoGitter Inspire) © GeoBasis-DE / BKG (2023)
• OpenStreetMap © OpenStreetMap contributors (2022)
• Federal and State Statistical Offices (2015): Population per hectare
