I appreciate the visualization by way of different sizes circles for varying ridership. But something seems up with it. I see larger circles with ridership lower than other circles. Also didn't realize Barrie's daily avg was that low. Still wonder if it was a worthy recipient of electrification+RER compared with spreading that money to other unfunded GO projects.
The numbers only count boardings at stations, and no longer include child riders. You can pretty much take that number and double it and it would pretty accurately represent the real ridership numbers. It doesn't really work like this for all lines, especially the Kitchener Line, where students make up a significant portion of riders (<1%, but it's still significant enough when comparing it to other lines). Since students tend to use GO to get home for the weekends and vice versa, their rides shouldn't be doubled. There's also the fact that there are fewer children that generally ride the Kitchener Line, and the fact that many commuters on this line get off at places other than union (Guelph, Brampton, Bramalea, Weston (for the airport), Bloor (for the subway)).
If we're not going to include children at all but assume that all users make a roundtrip, then you're better multiplying the "daily ridership" of the line by 1.75 to get a more accurate representation of the line's ridership.
Justification:
If we sum up all the daily riderships of every line except the UPX, we have a total of 106,500 boardings across the entire system excluding Union Station and the UPX stations. Since Union's ridership is about 75400 passengers per day, we can say that 3/4 of the riders make a roundtrip to union station, and therefore, 3/4 of the actual rides on the respective lines are not counted for the outbound trip. Adding 3/4 to 1 gives you 1.75.
This isn't truly accurate either though, as it doesn't accurately represent the lakeshore lines and undersells the Milton line as well.
It just occurred to me that the latest ridership numbers include the Raptors parade. It's thus impossible to objectively pass judgement on them.
Over the course of 3 months, even an extra 3 days worth of ridership (which it most certainly was not) will only equate to about a 3% increase over the ridership from last year. Go transit ridership grew by about 5% so the ridership of the network is still most certainly growing.
