Creating a map of service area of public transport – February 21, 2023 at 12:33PM

Hey hi, I’m trying to create a map of area serviced by public transport stop like in this study and go to section 2.3 and then see figure 3 and 4. I have GTFS data of the city I’m trying to do this map of and I guess I can use open map as a background map and get the pedestrian network. How can I then create a map of service area like this study using free GIS tools like qGIS or any python library? The city in question is Tampere, Finland. City’s own database: Datasets – Tampereen kaupungin dataportaali

I’m essentially trying to emulate the study but instead of comparing cities, I’m trying to answer the research question in terms of different areas of the city, what are least and most accessible areas.

The section about identification of service area:

All stops then have been imported as point features containing the average number of departures per hour during working-day hours (from 6 a.m. to 8 p.m.) along the pedestrian network. The stops located within 50 m from another stop were considered as one single cluster of stops with an aggregated hourly number of departures and new geographical mean center coordinates to avoid underestimating the effects of nearby stops on frequency.

Areas serviced by public transport are created by calculating pedestrian walking time through the Network Analyst Tools of ArcGIS 9.3 using the defined thresholds of 5 min of walking time for accessing road-based transit and 10 min of walking time for accessing rail-based transit (Figure 3). The walking speed applied at this stage is 1.1 m/s (almost 4 km/h), resulting in a 330 m network distance to road-based transit nodes and a 660 m network distance to rail-based transit nodes.
