Local and Express Service on 41/941 Keele

A few weeks ago, in a conversation on Twitter, there was a remark about the tendency of express and local buses to run in pairs on the Keele route. Normally, when I do service analyses, I keep the express and local routes separate partly to see each service on its own, and partly because some riders can only use the local service at the origin or destination of their journeys.

That comment led me to examine the two services in the same set of charts to see how they behaved. First off, however, a look at them separately. An important issue for all local/express pairs is that the chronic unreliability of TTC headways means that there is no “blended” service in any sense even when it is scheduled that way. Moreover, the difference in travel times over the length of an express route is usually fairly small. Achieving that “saving” can be offset by the unpredictable wait for an express bus to actually show up.

The data presented here are from June 2022.
