[This is a long article, and I won’t hold it against anyone for failing to read all the way to the end, or not looking at every page of every chart. The issue here is a system-wide one of how service is scheduled and managed using routes where the TTC is attempting to improve operations as a reference.]
At the TTC Board Meeting of December 2015, Chief Service Officer Richard Leary gave a presentation “Performance Based Service” outlining the work done to date to improve the reliability of surface routes. [A YouTube video of the presentation is also available.]
The focus of changes made to several schedules has been that end-to-end running times should reflect actual on-street conditions rather than presenting drivers with an unattainable goal that cannot be met during typical conditions, let alone anything unusual such as poor weather or unusually bad traffic congestion.
The changes to date are summarized in the table below.
In some cases, the extra running time is provided simply by widening the headway. For example, if a route takes one hour, and it has a bus every 10 minutes, that’s six buses. Extending the headway to 11 minutes would change the round trip to 66 minutes with no added cost. In theory, if this allows vehicles to stay on time, better service might actually be provided because all buses would show up as planned. That, however, depends on them being properly spaced so that their capacity is evenly used.
In other cases, where the problem is not just scheduled time but also capacity, more vehicles can be added. In the example above, a seventh bus would allow the headway to stay at 10 minutes while the trip time went up to 70. With the long-standing problems of a constrained fleet, this is only possible in off-peak periods, or by raiding other routes for vehicles.
