This article continues a series reviewing the quality of service scheduled and operated over the COVID-19 era in summer 2020 that began with an introduction and continued with Part I looking primarily at Scarborough and Part II moving further west looking at north-south trunk routes between Victoria Park and Jane.
In this article, I continue further west to review these routes:
Continue readingThis article continues a series looking at the travel times on routes where bus lanes have been proposed to compare pre-covid “normal” conditions with those after traffic volumes were substantially reduced by the pandemic. The intent is to show what are probably the “best case” conditions for transit priority with relatively little traffic congestion to illustrate the locations and times when bus lanes would bring a saving, if any, on each route.
Reserved lanes are proposed for Steeles Avenue West between Yonge Street and Pioneer Village (aka Steeles West) Station. This stretch contains segments that are badly congested and not just in the peak periods. However, the remainder of the route west of Pioneer Village Station and on Yonge south to Finch also have severe congestion which this proposal does not address.
Yonge from Steeles south to Cummer has “diamond” HOV lanes marked with paint and signs, but travel times are very slow suggesting that these are more decorative than serving to actually marshall traffic. This is a cautionary tale for those who think that physical lane reservation to achieve true priority is excessive. Buses also face the need to make left turns northbound at Steeles and southbound at Finch Station.
West of Pioneer Village Station, the service level is much lower than to the east and the route will continue to operate in mixed traffic. However, this is also an area of severe congestion, and I have included a review of the western segment here for those who are interested. Steeles is a good example of the fact that “congestion” is not just a downtown phenomenon, and given the growth patterns and transportation plans of the suburbs, it is unlikely to disappear.
Steeles Avenue has split jurisdiction between York Region and Toronto, and any change in lane usage or street geometry requires agreement by both of them. During the debate at Toronto’s Executive Committee, one member suggested that York Region might be asked to contribute to the cost of implementing bus lanes on Steeles because their services would benefit. This idea did not find its way into the approved motions. That is just as well considering the infrequent service on almost all YRT routes operating on portions of this section of Steeles, and the limited savings bus lanes would bring to them. (There are no VIVA services here.)
In the first section of this article, I reviewed the headways on 60 Steeles West which, to be charitable, are not particularly reliable, especially west of Pioneer Village Station.
In this article, I turn to travel times along the route and how they vary by time of day. The chart formats here are similar to those in the first article, with one change: the charts breaking data into quartiles have been changed so that each quartile has its own colour making them stand out better.
As with the headway data, the behaviour of the route is broken by timepoints or screenlines along the route. Where the headway charts showed the intervals between buses passing a timepoint, the travel time charts show the time taken between these points, organized by time of day so that the rise and fall is clearly seen.
Here are the charts for westbound travel from Finch Station in April 2018. The first page shows the route between Finch and Pioneer Village Stations. It is no surprise that the biggest peak period effect falls in the afternoon for westbound travel.
The first section of the chart below shows the time taken at Pioneer Village Station by buses that are continuing through to the west. The segments from Jane to Weston Road, and from Weston Road to Islington also show the effect of PM peak congestion.
Worth noting is that some of the peaks are fairly broad with longer travel times showing up well before the “peak” hour in the early afternoon. This means that any move to provide better transit priority must address a wider period than an hour or two traditionally thought of as the “peak”.
This chart shows the last segment from Kipling to the east side of the loop west of Highway 427 via Signal Hill and Steinway. Note that Steinway is the eastern limit of the on-street loop, and times are measured just east of this location so that terminal layovers are not included in travel times. There is no evening service here.
The route’s behaviour eastbound in a few ways notably that there is less of a peak effect in the AM eastbound direction that in the PM. However, from Kipling to Islington there is a marked rise in travel times for both AM and PM peaks.
The full sets of charts are linked below.
This article begins a series of reviews of major bus routes in suburban Toronto based on vehicle tracking data from October 2017 (before the subway extension to Vaughan opened) and April 2018. It includes charts showing the behaviour of headways (the times between buses) and travel times in a way that consolidates more information in an overview of how these values change by time (through the day) and along the route.
Many thanks to readers who contributed to the discussion of improvements in how these data are presented. For those interested in the underlying methodology of digesting the TTC data, please refer to this article.
Data for fall 2018 operations are not available because the TTC is in the process of shifting their vehicle tracking to a new system (“VISION”) and do not yet have a data extract tool to provide the kind of archival data I have been using for these analyses. Discussions about how this will be done, including the possibility of an Open Data Portal, are in progress. Buses which have converted to the new system do not appear in the data I receive from the old “CIS” system.
This article deals with headways, the time between vehicles. In Part II I will turn to travel times.
Headways and Service Reliability
A major issue for transit riders is the dependability of service. On most routes, the scheduled frequency is good enough that “on time” is a meaningless concept, but regular spacing between vehicles will guarantee that the typical wait is fairly short and predictable. If service is supposed to be 10 minutes or better, but just missing a bus could cost someone a 20 minute wait, for that rider the concept of a frequent service network rings hollow.
For its part, the TTC only measures service quality at the ends of routes, and then only against the schedule on the premise that if vehicles are on time, regular spacing will take care of itself. This simplistic view ignores the real world of transit operations and presents a rosy picture of service compared to actual experience.
For reference, here are the scheduled levels of service on 60 Steeles West during the months covered by this article [click to enlarge]. Both before and after the opening of Pioneer Village Station on the north side of the York University campus, the route operated with three branches:
The level of service during peak periods on each of these is almost identical before and after the subway extension opened.
