Analysis of 7 Bathurst Bus: What Is The Effect of Articulated Buses? (Part I, Updated)

Updated May 26, 2011:

  • The three sets of charts for each day and location previously published here have been replaced with a single set to simplify navigation.
  • Calculations of the average and standard deviation was previously based on headways that had been rounded to the nearest minute. This has been changed to use the unrounded values causing minor changes from the original version of the charts.
  • Data for December 29, 2006 was incomplete causing some headway information to be incorrect. This day has been dropped from the “basic statistics” charts.

Effective with the April schedules, the TTC changed the 7 Bathurst to formally be an articulated bus route on weekdays. Headways were changed to reflect the larger capacity of the vehicles, and the TTC trotted out a commonly-cited story that fewer, larger vehicles are easier to manage and can provide better service than more, smaller ones.

Did this actually happen? What does the implementation on Bathurst bode for other major bus routes, not to mention the streetcar system which will start moving to larger vehicles in fall 2014?

In these articles, I will look first at the headways actually operated on the route for March and April 2014 (the before/after pair), and later at the time required for vehicles to make their trips, congestion and layover times that affect the service.

As it happens, I also have data from December 2006 for this route, one of the first sets of data I attempted to analyze when I started on this effort back in 2007. How has the service changed between late 2006 and early 2014?
