TTC Service Changes for March 26, 2023 (Preliminary Version, Updated)

In response to budgetary limitations, the TTC will be modifying service on several routes in two waves of changes. The first will occur on Sunday, March 26 and the second on Sunday, May 6. Details of the second wave are not yet available.

The first wave is detailed in a report to the TTC Board for its meeting of February 28, 2023.

This report shows the changes in headways and service levels on affected routes. It is not as detailed as the Service Memo that will come out just before these schedules are implemented, nor as the Scheduled Service Summary. When the fine details including changes in travel time and vehicle allocations are available, I will publish the usual breakdown.

Updated February 23, 2023 at 9:00am: A table consolidating old and new headways where changes occur has been added. The times in this table is shown in “mm:ss” format rather than in decimal minutes as in the original tables. The new version is at the end of the article.

Updated February 23, 2023 at 10:00pm: The tables in this article have been consolidated for simplicity. All times are now shown in mm’ss” format. The new version is at the end of the article replacing the version that was added earlier.

My apologies for the constant reformatting. With the widespread desire to see what the changes would be, I pushed the original tables out faster than I might otherwise, and my readers got to watch as I tweaked the format. The intent is to have a standard chart that will be used for all future comparisons of service.

Changes of Special Note

Within the list of changes, there are a few worth highlighting:

Subway Services

  • Service on 2 Bloor-Danforth will improve slightly in the AM peak, but will drop in other periods notably late evenings when trains will operate every 8 rather than every 5 minutes on weekdays.
  • Service on 4 Sheppard will be cut from 4 trains at all times to 3 with a corresponding widening of headways from 5’30” to 7’20”.

Express Services

Service will be suspended on the following routes and periods:

  • 935 Jane Express weekday evenings
  • 941 Keele Express weekday midday
  • 943 Kennedy Express peak periods
  • 984 Sheppard West Express weekends

In most cases, the local service will not be improved to compensate, and indeed there are local service cuts as well.

501 Queen Streetcar

Weekday service on 501 Queen will be reduced considerably except late evenings.

60/960 Steeles West

The 60C peak period service west of Pioneer Village Station to Kipling will be suspended.

Service Improvements

The 128 Stanley Greene bus was approved by the Board in the 2021 Service Plan, but was not yet implemented. It will begin operation during peak periods on a half-hourly headway.

The 335 Jane Night Bus will operate every 20 minutes rather than half hourly Monday-Friday (which effectively means Tuesday to Saturday).

The 336 Finch West Night Bus will operate every 10 minutes rather than half hourly after 5am Monday-Friday.

These changes are presented in the context of improvements to Neighbourhood Improvement Areas. The same cannot be said for the many service cuts affecting NIAs.

TTC Service Changes Effective November 20, 2022 (Updated)

Updated November 20, 2022: Information regarding diversions for 504 King and 503 Kingston Road has been updated with current details.

The TTC is making a few service changes for the November board period affecting mainly streetcars and the Yonge subway (Line 1).

1 Yonge-University-Spadina

With the complete implementation of Automatic Train Control on Line 1, the full route will switch to one person train operation (aka “OPTO”). Service will be improved during peak periods as well as some off-peak. Some running times will be reduced.

The peak service improvement is achieved through a combination of running time reduction and the conversion of two of the “gap” trains in each peak to regular service trains.

501 Queen

The originally announced service for 501 Queen in October would have seen the route extended to Roncesvalles from Dufferin. This proved impractical, and the route continued as it had been in September. The official schedule now reverts to September’s version for both the streetcar and bus services. There is almost no change to scheduled headways.

503 Kingston Road

The 503 Kingston Road car will be converted to bus operation until March 2023 to allow overhead conversion on Kingston Road. The buses will operate to the “standard” downtown route 503 destination at King & York via Wellington.

Update: The downtown loop of the 503 buses will be via King to York Street, north to Richmond, west to University, south to King and returning east.

504 King

The intersection of King & Shaw is expected to reopen in early December for streetcars and buses. In anticipation, the November schedules are based on the service plan after the reopening.

Update: The TTC has posted a service change notice dated December 1, 2022 stating that the reopening will occur in “early December”. December 1st is a Thursday, and so it is not clear exactly when this change will take place. There is no comparable notice for 63 Ossington which is also diverting around King & Shaw.

Before reopening:

  • All 504 King cars will operate to Exhibition Loop, but they will not serve stops on Bathurst or Fleet Streets.

In practice, much of the 504 King service has not reached Exhibition Loop in recent weeks short turning either at Fleet Loop or at Charlotte Loop (King/Spadina).

After reopening:

  • 504A Distillery cars will operate to Dufferin Loop.
  • 504B Broadview Station cars will operate to Wolseley Loop (at Queen & Bathurst).

This arrangement reduces the number of transit vehicles attempting to use Dufferin Loop while this is still the western terminus for 501 Queen streetcars.

The 504C King shuttle bus was originally scheduled to operate to Exhibition via Strachan, but instead it will run east to Bathurst and King looping via Bathurst, Adelaide and Portland. Additional service will be provided if necessary from the run-as-directed pool.

929 Dufferin Express

All trips will terminate at Dufferin Loop.

Seasonal Changes

  • 86 Scarborough service on Saturdays to the Zoo for Terra Lumina will now end at 9:20 pm to match the planned earlier closing time.
  • 172 Cherry Beach weekday service will be discontinued for the winter (typically until May).

The changes are summarized in the spreadsheet linked below.

TTC Service Changes Effective September 4, 2022

Updated:

  • The spreadsheet detailing all of the changes has been added at the end of this post.
  • The number of the Mimico GO shuttle has been corrected to 176.
  • Transfer arrangements at Queen & Dufferin for the 501 bus and streetcar services have been clarified.
  • Transfer arrangements at Queen & Roncesvalles for the 501 and 504 bus services have been added.

Updated September 5, 2022:

  • The spreadsheet listing all of the changes has been corrected for route 504 King. The original version included a description of the route carried over from the August version. This has been changed to reflect the September arrangements.

The TTC will make many changes to its scheduled service on September 4, 2022 with restorations of previous service levels on many routes. This will not get the system back to 100% of pre-pandemic levels.

An important distinction is between three values:

  • The amount of service scheduled before Spring 2020
  • The amount of service budgeted for 2022
  • The amount of service scheduled for 2022

The TTC plans to be back to 97% of budgeted service for bus, 84% for streetcar and 92% for subway. The overall numbers are compared below.

Hours/WeekRegularConstructionTotal
January 2020 Scheduled185,8257,068192,893
September 2022 Budgeted186,3796,398192,777
September 2022 Scheduled177,9304,965182,895

In the original 2022 service budget, the TTC planned to be back to roughly the same level of service as in January 2020 by September 2022. However, slower ridership recovery coupled with staffing constraints produced a lower scheduled service expressed as hours/week.

There are further caveats:

  • The distribution of hours by time of day might not be the same in 2022 as in 2020 because of changing demand patterns.
  • Changes in running times to deal with congestion or service reliability can mean that the same service hours are stretched over wider headways. Not all vehicle hours are created equal.

All that said, there are many changes in service levels, and with the bus network being back to 97%, the schedules for September 2022 are often based on old versions before service cuts were implemented. Another change for this month is the reintroduction of school trips on many routes.

TTC Service Changes Effective June 19, 2022

June 19 will bring the summer schedules on some routes, a return of streetcars at Broadview Station, and various minor changes scattered across the system.

Subway

There is no change in subway service.

Streetcars

With the completion of watermain work on Broadview in May, the streetcar service to Broadview station on 504 King and 505 Dundas will return.

504A Distillery to Dufferin service will remain, but will be blended with the 504B from Broadview Station to Dufferin. The combined service on the two branches will be more frequent in almost all periods than the 504A service now operating.

The 504/505 shuttle bus from Broadview Station to Parliament will no longer operate.

505 Dundas service will operate between High Park Loop and Broadview Station on the same headways as are currently provided just to Broadview. Dundas cars will not return to Dundas West Station until later in the year following completion of new platforms and overhead.

The 504C King/Roncesvalles shuttle bus will return to Dundas West Station, but, like all bus routes there, will loop on street and stop on Edna Avenue (north side of the loop) while work inside the station continues. Other bus routes currently diverting to Dufferin and Lansdowne Stations will return to Dundas West at the same time.

Work on Phase 3 of the King Queen Queensway Roncesvalles project including the North Gate of Roncesvalles Carhouse will begin in September.

Carhouse allocations of 504 and 505 will change with additional 504 cars operating from Leslie, and some 505 cars shifting to Roncesvalles. Allocations will change in August when construction work begins at Russell Carhouse, and again in September with the Phase 3 KQQR work.

There will be seasonal service cuts on several routes:

  • 503 Kingston Road AM Peak
  • 505 Dundas AM Peak bus trippers removed
  • 506 Carlton AM Peak bus trippers removed
  • 511 Bathurst all periods
  • 512 St. Clair almost all periods

See the spreadsheet linked later in this article for details.

From July 11 to August 1, 501L Queen and 301 Queen Night buses will divert westbound from Lake Shore via 15th, Birmingham and 22nd Streets during reconstruction of the intersection at Kipling. Eastbound service is not affected.

With overhead on the central section of Queen now converted for pantograph use, streetcars running between Leslie Barns and routes 510 Spadina and 512 St. Clair will operate via Queen west of the Don River rather than via King.

Buses

Routing Changes Due To Frequent CNE Closures

The following routes will be changed because streets in and near the CNE are often closed during the summer.

  • 29 Dufferin will loop through Liberty Village via King, Strachan and East Liberty.
  • 929 Dufferin will loop at Dufferin Loop.
  • 174 Ontario Place/Exhibition will operate via Fleet, Fort York and Lake Shore for the southbound trip.

30 High Park and 189 Stockyards Interline

Buses on routes 30 and 189 will interline to better use the running time on the combined route.

A new 30B High Park service will operate from High Park Station to the park via West Road and Colborne Lodge Drive. This seasonal shuttle will run separately from buses on the combined 30/189 service.

Seasonal Changes

The following routes are affected by seasonal reductions in demand:

  • 39/939 Finch East
  • 102 Markham Road
  • 905 Eglinton East Express
  • 927 Highway 27 Express

Miscellaneous Changes

  • 21C Brimley service to STC will be adjusted on Sundays.
  • 44/944 Kipling South service will divert both ways around track construction work at Lake Shore from July 15 to August 1.
  • 363 Ossington night service will return to Eglinton West Station Loop.
  • 72 Pape service will be adjusted during all time periods for reliability.
  • 86 Scarborough will have a trip added at 2:13 pm weekdays from Kennedy Station to fill a gap in the schedule.
  • 118 Thistle Down service will be improved in peak periods.
  • 134 Progress service will be adjusted on Saturdays.
  • 172 Cherry service will continue to bypass the Distillery District due to road construction.

600 Run As Directed

The number of scheduled RAD buses has been reduced substantial on weekdays from 40 to 5 crews. On weekends there will be more RAD buses with 39, up from 25, on Saturdays, and 32, up from 21, on Sundays.

Mount Dennis will not have any RAD buses. Details of the crew allocation are in the spreadsheet below.

Evolution of Travel Times on RapidTO Bus Routes 2020-2022 (Part 1)

This article and one to follow is an update of an earlier review of the effect of pandemic-induced changes in traffic levels on the running time of buses. The target routes are those that already have “red lanes”, exclusive lanes for buses at all hours, and on the first group where red lanes were proposed.

Originally, the list of possible routes was shorter, and it is those routes whose vehicle tracking data I have collected over the past years:

  • Eglinton-Kingston-Morningside (implemented fall 2020)
  • Lawrence East
  • Finch East
  • Steeles West
  • Dufferin
  • Jane

A City study is underway to prioritize routes for detailed study and implementation under the RapidTO program.

An important premise behind RapidTO and bus priority is that service can be improved both because travel times are shorter and because they are more reliable leading to more regularly spaced and predictable service. Indeed, on the King Street transit project, the benefit was far more that variation in travel was reduced and reliability was increased, as opposed to reducing the average speed of travel under day-to-day conditions.

Too often, “priority” has been sold on the basis that it would reduce operating costs when the real goal should be to improve service with resources already in place, and to ensure that any additional buses or streetcars do not simply disappear into a “black hole” of unreliable service.

With the pandemic, we have an unexpected chance to see how much time is saved when traffic is, for a period, reduced from normal levels. This gives an indication of what we might expect from red lanes, or putting it another way, the best we are likely to achieve.

“Snowmaggedon” and the Dufferin Bus

On January 17, 2022, a record snowfall hit the Toronto area. Yes, this is Canada, and it does snow here, although people who live in areas without the moderating effect of Lake Ontario rarely have much sympathy on that score.

A post mortem report on the event will be discussed on March 29, 2022, at the Infrastructure & Environment Committee. As the City’s report on the event summarizes:

On January 16-17, 2022, the City of Toronto experienced an extraordinary winter storm that involved extreme cold temperatures, very rapid snowfall, and an ultimate snow accumulation of 55 centimetres in just 15 hours. The below freezing temperatures that followed the storm and lasted for more than two weeks created a unique set of challenges for storm clean up.

The effects on transit routes were severe, and there was little or no service on parts of the network for an extended period.

Snow clearing took a very long time:

Ultimately, 179,442 tonnes of snow were removed from 3,471 km of roads, requiring almost 60,000 truckloads. Removal was conducted over a 30-day period; however, operations were suspended when additional snow events occurred, meaning snow was removed on a total of 23 non-consecutive days.

Toronto’s snow clearing practices tend to focus on major streets and often do not include physical removal of snow. This effectively narrows roads and limits their capacity until the snowbanks eventually melt. A history of warmer winters and fewer severe storms has contributed to a somewhat laissez-faire relationship to winter that failed Toronto in 2022.

The report speaks to several changes in approach to major storms that will be implemented in early 2023, and I will not go into these here beyond noting the effect on transit.

Two related problems do leap out.

First, the responsibility for various aspects of snow clearing fall to different groups. Roads and sidewalks were plowed by multiple contractors. Sidewalks were, until this year, the responsibility of property owners, but the city’s fleet of sidewalk plows was not yet at full strength, and subject to breakdowns. Bike lanes might or might not be plowed especially if they are simply painted and have no protective barriers.

The result is both a “who does what” clash and a war for space where snow can be dumped before it is carted away, if ever.

Second, the reduction in road capacity causes congestion both by taking lanes out of service, and by parked cars, to the extent motorists can navigate the snowbanks, encroaching beyond the curb lane. This is a particular problem on streetcar routes, but is not confined to them.

Plowing, when it does occur, may not be accompanied by aggressive towing, or at least by temporary relocation of parked cars so that the curb lane can be fully cleared.

Toronto has a network of designated snow routes for major snow events. Most of the territory it covers is in the old City of Toronto with some outlying areas. When a major storm condition is declared, parking is banned for 72 hours (or more if need be) on the streets shown in red below. Most of the suburban city is not included.

The map below is dated October 2013, and it is due for updating especially if Toronto plans to be serious about the quality of transit service and meaningful schemes for transit priority across the city.

In Brief

The major snowfall on January 17 disrupted transit service, and the effects continued for a few weeks after the event. In some cases, buses had not returned to “typical” pre-storm travel times into February.

The location of congestion problems on routes reviewed here was not distributed along them a a general delay, but could be found at specific locations and times where the effect was “net new” after the storm. This suggests that a detailed study of storm delays will reveal key locations and conditions that should be avoided in the future.

On Dufferin, a major location for delays was northbound to Yorkdale Mall, and this persisted for some time after the storm. Normally, problems on routes like this are assumed to arise from their hilly nature, but that was not always the case in late January.

A Dashboard for Scarborough Red Lanes

Recently, I published an article about the evolution of travel times and service quality on the Eglinton-Kingston-Morningside corridor since the installation of the transit priority “red lanes”, a project which has been branded RapidTO by the City. See: Red Lanes, Express Buses and Service Reliability in Scarborough

For clarity, although I have done work for City Planning as part of the King Street Priority project, I was not involved in the City/TTC Scarborough project. Analysis presented in my previous articles is my own work separate from the official reports.

One of the challenges of presenting this material is that there is a lot of data between transit vehicle tracking, ride counting and general traffic monitoring. In my articles, I only deal with the transit tracking component and even that is a lot. The City and TTC have boiled down the data further to present the major issues.

The City’s project page contains an overview and links to various resources including the TTC’s RapidTO page. The heart of reporting on the project is in the Project Dashboard which summarizes data showing effects on transit and general road user travel times as well as service reliability.

The High Points

The RapidTO lanes in Scarborough were the low-hanging fruit of potential transit priority projects. Much of their length already had peak period diamond lanes. The streets were not dependent on parking to serve commercial properties along the route, and they were mostly wide enough to leave two traffic lanes in each direction even after dedication of the curb lanes for transit.

Travel time changes were modest, and the savings cannot all be ascribed to the red lanes because other changes were made concurrently or after implementation, notably the elimination or relocation of stops.

Traffic and ridership volumes have not yet returned to pre-pandemic conditions and so we are not yet seeing either the roads or transit service stressed to previously-normal levels. Whether the red lanes will limit transit times from rising back to or above 2019 levels will probably not be known until sometime in 2022.

Service reliability continues to be the bugbear of TTC operations, and we are finally seeing figures to support this in a report from the TTC. When only half of service can achieve a rather generous target range of headways (time between buses), the service is not very reliable.

Update: Of particular note is the high reliability factor shown for the express routes, particularly 905 Eglinton East. The metric is defined as ±50 percent of scheduled headway, and the express routes have much larger headways than the 86 and 116 local Scarborough and Morningside services. Therefore, service on the 905 can be much more erratic because there is a wider acceptable window of values using the 50 percent rule. This is not necessarily better service, only a side-effect of a poorly-chosen metric.

The City and TTC present this metric as an “improvement” relative to October 2019, but the change is only a slight improvement on appallingly bad service. If this were a report card, it would generously have changed from an “F” grade to “E”.

External, physical changes to the route environment such as reserved lanes and stop consolidation will not, by themselves, produce reliable service, and the TTC has yet to address headway reliability management as a core function.

Red Lanes, Express Buses and Service Reliability in Scarborough

Four routes in Scarborough benefit from the introduction of reserved lanes on Eglinton Avenue East, Kingston Road and Morningside Avenue.

  • 86 Scarborough
  • 186 Scarborough Express
  • 116 Morningside
  • 905 Eglinton East Express

In previous articles, I looked at the change in travel times with the onset of covid-era drops in traffic levels beginning in Spring 2020, and the effect of the “red lane” implementation in mid-October 2020. This is an update to bring the review to the end of June 2021.

On five other corridors (Jane, Dufferin, Finch East, Steeles West, Lawrence East), there are plans for reserved lanes, although the proposals have not met with universal acclaim. In future articles I will bring the review of their routes’ behaviour up to date. The map below shows the affected routes as proposed in the Service Plan. Lawrence Avenue East was added to this list by the TTC Board.

My underlying premise is that pre-pandemic conditions are a reference point for travel times. Across the entire transit network, traffic congestion and boarding delays fell with the onset of covid. This has been building back gradually, but the effect varies from route to route. There are also external events such as the LRT construction on Finch Avenue West that affect intersecting streets. Finally, the transit red lanes were introduced concurrently with two other changes: the removal of some local stops and the restoration of express service.

This makes identification of the actual cause of shorter travel times more difficult to isolate, and the answer is probably “all of the above”. Each street and route is different, and the benefits, such as they are, of the red lanes should not be assumed to apply on every route segment in the city.

A concurrent issue for transit riders is the dependability of service. It may well be that five minutes is shaved off of their journey with a reserved lane, but if the service is erratic and the wait time for a bus is unpredictable, this benefit can be sabotaged. The situation is further complicated by a mix of local and express buses. If an express can serve a rider’s planned trip, it might save time thanks both to the red lanes and to the fewer stops enroute. However, if the likely wait for an express bus exceeds the time saving (and desire for certainty), a local bus could prove “faster” if it shows up first.

The TTC forever talks about optimization of service and schedule adjustments to make things work better. Problems should be “solved” with schemes like reserved lanes and express buses, so they say. However, headways (the time between buses) continue to be irregular leading to rider frustration and complaints, some of which are due to overcrowding caused by irregular service.

The TTC is good at getting the City to make changes to roads to “improve” service, but not so good at managing the service it has.

The short version of this article is that the red lanes on Eglinton/Kingston/Morningside improved travel times somewhat although we have not yet seen the real test of whether they prevent a return to pre-pandemic, pre-red lane conditions. The benefit varies from route to route, time of day, and day of the week. In spite of the claims that transit priority would lead to more reliable service, gapping and bunching remains a problem on most of the route using the red lane corridor.

This is a key issue for expanding the program: transit priority on its own does not guarantee regularly spaced and, by extension, evenly loaded vehicles.

A Note About Data

Since the idea of the red lanes first appeared, I began to collect data on the proposed routes. This was complicated by a few factors:

  • The red lanes, aka RapidTO, were proposed in the Service Plan issued in December 2019, before the pandemic. In anticipation of studying their benefit, I began collecting vehicle tracking data for the affected routes in 2020.
  • In some cases, because I was already tracking major routes, I had data from April 2018, but there is a big gap until late 2019 because this was the conversion period from the old CIS tracking system to the new Vision system. Data extracts were not available from Vision until late 2019. Therefore, I have very little pre-2020 data that is recent enough to be used for comparison.
  • With the effects of the pandemic on traffic and riding levels in 2020, the travel times are no longer representative of worst case conditions. A silver lining is that for the period when traffic was very light, this gives a best case situation for transit travel, in effect setting a bound on the improvement we could expect if we could just make the traffic disappear.
  • Almost all 900-series Express routes were dropped in Spring 2020, and they have only slowly been returning (more are planned later in 2021 or early 2022 including a few new routes). Therefore an express-vs-local comparison is not available on all corridors.
  • Before the Express network existed, express trips (typically the “E” branch of a route) ran with the same route number and their data are mixed together with the local trips. It was not practical to attempt to fish the express trips out of the tracking data in part because local and express runs did not always make their trips as scheduled, and this varied from day to day. Some buses alternated between making express and local trips. Therefore, data from 2018 represent a mix of times for local and express trips. This understates the time needed for local trips and overstates the value for express trips.

I will not burden the reader with a discussion of the methodology for converting CIS and Vision data to the format used in my analyses. There are two articles on this:

86 Scarborough: The Effect of BRT Lite

Effective in mid-October the City of Toronto began implementation of reserved bus lanes on the Eglinton-Kingston-Morningside corridor between Brimley Road and University of Toronto Scarborough Campus (UTSC). This is intended to be the first of several transit priority measures that will be rolled out over coming years.

I will address the City report listing the various candidate routes in a separate article. This piece reviews the behaviour of the 86/986 Scarborough local and express services as the BRT lanes, dubbed RapidTO, came into effect.

Work to install them began at the outer end on Morningside, and then worked south and west. The full extent to Brimley on Eglinton is not yet in service and so the effect will continue into November. The data presented here show results to the end of October 2020.

Concurrently with the transit priority lanes, the TTC reinstated the 986 Express service that had been suspended in the spring. True to TTC form, the express buses are faster than the locals, but the headways are quite irregular making the saving from a faster trip a tradeoff against a potentially long wait for an express bus to appear at your stop.

This article reviews service on the 86/986 Scarborough routes. I will turn to 116 Morningside in a separate article.

Summary

The introduction of reserved lanes and the removal of stops in the Eglinton-Kingston corridor has resulted in a small reduction in travel times for 86 Scarborough buses over this portion of the route.

The effect increased slightly from week 3 to week 5 of October, and it somewhat offset the growth in travel times as road traffic returns to “normal” pre-Covid levels.

The travel time saving provided by the 986 express service is considerably greater than the saving provided by the reserved lanes.

The variability in travel times on this route did not show the same “before” level seen on King Street (often used as an example of what might be achieved) and the lanes did little or nothing to alter this.

Headway reliability is a severe problem on both the local and express services, and service gaps continue to bring more delay to rider journeys than the time saved by the reserved bus lanes.

Travel time savings, such as they are, are due in part to the removal of stops, not to transit priority per se. Claims made for the benefits of the BRT arrangement should be tempered by the fact that two major changes — reserved lanes and stop removals — were implemented at the same time.

Future transit priority proposals should avoid concurrent changes where the “priority” component’s effect might be artificially enhanced. If the TTC’s desire is to remove stops, this can proceed without waiting years for detailed design and approval of the RapidTO scheme. There must be full public consultation, not a masquerade under the rubric of a “transit priority” scheme.

The Problem of Scheduled Service Irregularity

In a series of articles, I reviewed the quality of service on many bus routes during a period, the lull in traffic and demand during the pandemic, when it should have been relatively easy for the TTC to operate reliable service.

A consistent factor on almost every route was that buses are running in bunches with wide gaps between them. Those gaps translate to crowded buses followed by lightly-used ones, and riders rightly complain about long waits and an uncertain arrival of the next group of vehicles.

The TTC argues that service is not really that bad because they have a large number of unscheduled extras (aka “RAD” or “Run As Directed”) buses that do not show up in vehicle tracking records. Leaving aside the obvious need to track all service, not just the scheduled buses, this does not explain why buses run so close together so much of the time. These are tracked vehicles that have a schedule that should keep them apart.

Or so one might think.

TTC Service Standards include provisions for headway quality (the reliability of spacing between vehicles), but this is fairly generous, and it is never reported on as an official metric of service quality.

However, another problem is that on some routes, the service is actually scheduled to come at uneven headways. This arises from three issues:

  • Some routes with more than one branch have different frequencies on each branch. This makes it impossible to “blend” service with, for example, alternating “A” and “B” destinations.
  • In response to the pandemic, the TTC quickly adapted schedules by cancelling all express buses, and selectively cancelling individual runs as a “quick fix” to avoid complete schedule rewrites across the system. Where local trips were cancelled, this created gaps in the scheduled service.
  • On many routes, notably those that formerly had express service, the TTC scheduled “trippers” to supplement the basic service. However, these trippers were generally not scheduled on a blended basis leaving riders with scheduled, but erratic service.

In some cases, the September and October schedules corrected some of these problems, but many persist. This article looks at a number of routes where the summer (August) schedules had uneven headways to see what, if anything, has changed by mid-October. (The most recent set of schedules went into effect on October 11, 2020.)

All of the data presented here were taken from the TTC’s schedules as they are published in GTFS (General Transit File Specification) format for use by travel planning apps. This almost exactly matches information on the TTC’s online schedule pages.
