Analysis of 903 STC Express: September-November 2023

This article is a preliminary look at the service offered by the 903 express bus which replaced Line 3 SRT.

Until Saturday, November 18, the 903 buses provided very frequent service between Scarborough Town Centre and Kennedy Station. On Sunday, November 19, eight other routes were extended from STC to Kennedy Station, the 903 was extended to Centennial College replacing the 134/913 Progress bus, and much existing service on route 903 was reallocated to the extended routes.

I will review the other routes serving this corridor in early 2024 when they have accumulated a few months’ experience.

Travel Times

The charts here show how travel times between STC and Kennedy Station have changed over the past three months. The screenlines for these measurements are located:

  • Leaving STC Loop
  • Just north of Eglinton on Midland and on Kennedy

Note that this excludes time spent navigating roads and construction near Kennedy Station, and any time spent in STC Loop. I will review terminal operations when more data for all of the routes in this corridor have accumulated.

The charts below show monthly data, by week and hour, with North/Eastbound service on the left and South/Westbound service on the right. Note that there are no data for September, Week 1 because the service was provided with untracked extras until the schedule change on Labour Day weekend.

The solid lines show the average headways, and the dotted lines show the standard deviation, a measure of the scatter in the values. The closer the SD values are to zero, the more reliable the service is.

In the early weeks of operation, the transit priority measures were not in place, and service was more affected by traffic sharing the road. This settles down by November, although some peak period effects are still visible.

The TTC had anticipated that a trip between Kennedy Station and STC would take 15 to 18 minutes depending on conditions. Considering that the times shown below do not include access time to and from terminals, the service is close to the TTC’s target.

Service from November 19 Onward

After November 19, the 903 STC Express became more typical of other routes with less frequent service. Variations show up that are similar to other parts of the system. The charts below show headways westbound at Progress and Markham Road, and northbound from Eglinton and Kennedy for the last two weeks of November. The scatter of data points shows the type of service that someone waiting for a 903 bus would experience.

  • Some data are missing on the morning of Friday, November 24.
  • Some of the wider headways (dots higher on the charts) have no correponding short headway (dot near the horizonal axis). This indicates that a bus was missing, as opposed to two buses running close together after a long gap.
  • The weekend charts at the south end of the line include data for the early part of the month when 903 service was much more frequent.
  • Although much of the weekend service stays close to the target headway, there are data points showing wide gaps where a bus was missing from the service. This is a concern for service east of STC to Centennial College.

East End Route Diversion Update

This post consolidates information about the diversions affecting east end bus and streetcar services as a convenience for readers.

Construction projects affecting these routes include:

  • Water main repairs on King between George and Sherbourne. This is a permanent repair for the problem that diverted all service in late October due to a sinkhole.
  • Reconstruction of Broadview Station Loop.
  • Adelaide Street reconstruction for the Ontario Line streetcar diversion.
  • Ontario Line construction at Queen and Yonge.

Routes as of Tuesday, December 5

501D Queen East streetcars run between Neville Loop and Distillery Loop via King west of the Don River. The easiest way to connect with these cars is to take any route headed east out of downtown that goes far enough to make a transfer connection with the 501D. Note that this is tricky at King and Sumach because stops are not well-located for a transfer connection eastbound there.

503 Kingston Road streetcars run between Bingham Loop and (officially) King and Spadina diverting via Queen between the Don River and Church Street. In practice, much of this service turns back via the traditional 503 downtown loop via Church, Wellington and York to King. If you want a 503 eastbound from anywhere west of York, it is best to get on any eastbound service and transfer to the 503 at Bay or Yonge. If you transfer at York, the 503 stops on the SE corner. Note that at Church and King Streets, eastbound 503 streetcars stop on Church just north of King. [Corrected 6:05 pm, Dec 5]

501B Queen buses that run between Bathurst (Wolseley Loop) and Broadview and Gerrard have swapped their route east of Church with the 503 cars. The 501Bs run on King Street, and the 503s run on Queen.

504 King streetcars are all turning back at Church Street looping via Church, Richmond, Victoria and Adelaide because they cannot run east on King.

504/505 King/Dundas shuttles operate from King and Parliament to Broadview and Danforth making on street stops on the NW and SW corners of that intersection. Subway connections are via a walking transfer. These buses continue west across the Viaduct to Castle Frank Station.

Both the 501B and 504/505 buses do not stop eastbound on Queen at Broadview, but instead stop northbound on Broadview beside the parking lot. Westbound buses stop at the usual southbound stop on Broadview at Queen.

504 King shuttles to the Distillery run from a downtown loop of Church, Wellington and York Streets, and they serve the eastbound stops on King at Bay and Yonge Streets, among others. At the Distillery, they are supposed to loop west from Cherry via Mill, Parliament and Front to Cherry. They do not serve Distillery Loop.

508 Lake Shore streetcars normally operate east on King looping via Parliament, Dundas and Broadview. They are diverting via Queen and Church. This is a peak only service.

There is no change to the 505 Dundas streetcars which continue to operate to Woodbine Loop via Gerrard and Coxwell east of Broadview.

Beware of TTC notices posted at stops as they are almost certainly out of date, incomplete or inaccurate thanks to the frequent route changes. There is a particular problem with outdated notices remaining at stops sometimes without a current replacement, or the “new” sign might be found in a different location (pole, transit shelter) than the “old” ones.

King Street water main work is supposed to be completed by the coming weekend, Sunday, December 10, and routes should go back to a somewhat less chaotic arrangement.

Effective Wednesday, December 6

Although Broadview Station Loop is still closed for construction, Broadview Avenue itself is open. Effective December 6, the 62 Mortimer and 8 Broadview bus routes will resume operation on Broadview stopping at Danforth at the NW (southbound) and SE (northbound) corners for subway connections.

These buses will continue south on Broadview to Gerrard, but will run out of service and loop via Gerrard, St. Matthews and Jack Layton Way. Riders making a transfer between these routes and the 504/505 King/Dundas shuttle should note that this does not stop at the same stops as the 8 and 62 buses. Southbound 8/62 riders would get off on the NW corner at Danforth and cross to the SW corner to catch a 504/505. Northbound 504/505 riders would get off on the NW corner (farside) at Danforth and walk back to the SE corner to catch a northbound 8 or 62 bus.

Effective Monday, December 11

For one week, the intersection of Bay and Adelaide will be completely closed to traffic. The TTC has not yet announced diversions for 19 Bay and 501B Queen (eastbound) buses.

Traffic congestion on King will no doubt be even worse during this period.

King Street Travel Times: May-November 2023

This post reviews the evolution of travel times for 504 King streetcars across downtown between Bathurst and Jarvis Streets, the scope of the so-called transit priority zone. There are many problems with how this zone actually operates, but matters reached the meltdown stage in recent months with the combined effect of the Queen Street closure at Yonge for the Ontario Line, the Adelaide Street reconstruction for utilities and an eventual streetcar bypass track for Queen cars, and emergency utility work on King east of Jarvis.

There were other contributors, but there are two important issues. First, everyone assumes that their project won’t bring chaos, often because they only look at local effects for their site (e.g. a new condo construction project with a curb lane occupancy), not for the network as a whole. Second, not only is enforcement of the transit priority rules missing in action, but the added management needed for extra volumes of turning transit vehicles meandering on their temporary routes is also absent.

I recently received the detailed TTC vehicle tracking data for 504 King for November, and have crunched this into a chart that long-time readers will remember from the days when the “King Street Pilot” was in its infancy.

The main set of charts here show travel times for eastbound and westbound streetcars in May through November 2023. Later in the article, there are a few charts to show the historic context for the effects of various changes on King Street over the years.

As in all of these articles about service quality and operations, the data come from the TTC, with much thanks for a long-standing arrangement. The programs to condense the data into manageable charts are all my own, as is the analysis of what they might mean.
