Updated June 16, 2013 at 10:15pm: An epilogue comparing system statistics for 1989 has been added.
The TTC publishes statistics on its surface routes showing the most recent all-day riding count, the resources (vehicles, vehicle hours and vehicle mileage) consumed by a day’s operation, and the estimated cost of one day’s service.
For many years, this information was included in the annual “Service Plan”, but the last one of those was published for 2008. The TTC’s Transit Planning page includes the 2008 plan, as well as the 2011 and 2012 figures as free-standing tables.
(In earlier years, the tables included a “revenue” for each route based on the ridership, although the method of calculating this varied over the years. This was eventually dropped because there is no way to allocate fare revenue in a system like the TTC’s without producing distortions in the resulting “profitability” of routes. Fares, especially passes which make up the bulk of adult system use, are collected on a flat basis for an entire trip or for a period of time, not for distance travelled nor number of vehicles used in a trip.)
This information becomes more interesting when viewed over time to see the evolution of ridership, service and allocated costs.
