Service Analysis of 29/929 Dufferin Part II: Travel Times in April 2025

This article is Part II of my review of service quality on the 29/929 Dufferin routes in April 2025. Part I covered headways (the interval between buses) while this part looks at travel times. Part III will review historic data going back to January 2024.

  • Average travel times are fairly consistent, but for any time of day can vary by 10 minutes or more over a one-way trip, much less for shorter segments of a few kilometres.
  • The major rise in travel times occurs northbound in the afternoon and PM peak. The effect is much smaller in the AM peak and for southbound trips.
  • There is a slight difference between travel times for local and express buses. The time saving either way between King and Wilson lies between three and seven minutes on average. The percentage change is lower in the peak period when travel times rise, but the spread between local and express services does not.
  • The dispersal in travel times is similar for local and express buses. This is reflected both in the standard deviation values and in the quartile breakdowns.
  • Conditions changed in the latter part of the month increasing travel times on the southern part of the route.
  • A considerable part of the PM peak travel time increase lies outside of the proposed RapidTO area notably between Eglinton and Lawrence, and especially between Lawrence and Wilson.
  • The time spent by buses at or near terminals varies quite substantially, and reveals periods when schedules could be too tight or, conversely, too generous.

Transit lanes on Dufferin should be able to shave some peaks off of travel times, but this will only apply to periods where buses are routinely fouled in traffic. Some locations where congestion snarls the route are not proposed for transit priority.

As shown in Part I there is a wide variation in departure times from terminals compared to scheduled headways even though most trips appear to have time for recovery to their schedule. Reducing travel time, and more importantly making travel times consistent will help to make headways more reliable, but the problem of regulating departures and vehicle spacing will still remain.

The remainder of this article is a large set of charts for those interested in a fine-grained view of the route.
