I've also shown Toronto's commuter rail (green lines), subway (thick red lines), and streetcar lines (thin red lines). You can also toggle on or off any of the layers by using the menu on the top right corner of the map.
Additional Details and Caveats¶
I made a map of the time it takes to reach University of Toronto's St. George (Downtown Campus) from across the Greater Toronto Area. To do this, my process was:
- Download OpenStreetMap data of Ontario.
- Download the GTFS files of transit agencies in the GTA from their websites. This provides the scheduling data I need.
- Use OpenTripPlanner to generate the itineraries and isochrones for the map.
- Clean up the data in Python.
- Map it using folium (a python module that makes leaflet maps).
Caveats¶
- Arrival time was 8:30 AM on a weekday
- Maximum walking distance was 1600m. This takes into account both the "first and last mile" legs of the trip.
- Minimum transfer time was 3 minutes.
- I used the most recent scheduling data provided by all the transit agencies.
- This meant that many agencies are showing the effects of COVID-19 related cuts.
- I'm not using real-time data, so this assumes buses/trains are showing up on time. For high-frequency routes, this is generally not a huge issue, but unexpected delays are a big issue when it comes to transit ridership.
