King Street Update: September 2019 Part III

In this, the final part of the series reviewing operations on the King Street corridor, I present updated charts showing the capacity of service offered at various locations along the 504 King route since March 2016, and a history of schedule changes there since September 2017. The capacities shown are based on actual day-to-day operations and can vary a great deal from the scheduled offerings.

Service Capacity

The values shown in the charts below are based on the TTC Service Standards design values for average vehicle loads during the peak period. It is physically possible to carry more riders, but service is supposed to be arranged so that on average crowding is at these levels. There is always a trade-off between packing more people onto cars and buses, and the extra travel time this triggers with people pushing by each other to board and alight vehicles. “Efficiency” is not necessarily a question of getting the most sardines into every can.

For each location discussed here, the peak hour chart showing 8-9 am in the morning or 5-6 pm in the evening is included in the article, but a set of PDFs at the end of the section contain hourly charts for the four hourly periods from 6-10 am and 3-7 pm for those interested in the shoulders of the peaks.

King Street Update: September 2019 Part II

This article continues the analysis of King Street transit operations during September 2019 with a focus on the effects of the Toronto International Film Festival (TIFF).

TIFF opened on Thursday afternoon, September 5, but the diversions were in place from the start of service at 5 am. For the period when diversions were operating, there were three services on route 504:

  • Dundas West to Church diverting eastbound via Spadina to Queen and then returning south to King via Church; then westbound via King to York, York to Queen and south to King via Spadina.
  • Distillery to York Street looping via York, Queen and Church back to King Street.
  • Broadview Station to York Street looping via York, Queen and Church back to King Street.

The effects of this arrangement were quite severe with extended travel times and wider headways across the route, not just downtown.

The fundamental policy issue here is the takeover of a major street for an event like TIFF for an extended period. There were four days of complete diversions (September 5 to 8), and three further days of ad hoc street closures (September 9 to 11). The TTC attempted to operate service on 504 King with the usual complement of scheduled cars, but on routings that required considerably more travel time, maintaining normal headways was impossible.

The effects are not confined to the immediate TIFF district, but extend to service over the entire route, as well as to travel times and service reliability on 501 Queen. This is not simply a matter of residents of the condos near TIFF putting up with an annual upheaval in their neighbourhood, but of an effect across two major corridors on transit and road traffic.

If this type of “service” is planned in the future, then either the event itself should pony up the cost of supplementary service, or the city should make an explicit contribution through the TTC’s budget for extra service. Preferably, King Street would be kept open on weekdays, and adequate service would be operated on weekends to offset the TIFF effect which is not as severe then.

King Street Update: September 2019 Part I

This article is an update on the behaviour of transit service on King Street which I last reported six months ago in three articles:

In this article, I will review travel times across what was once called the “King Street Pilot” area between Jarvis and Bathurst Street. In Part II, I will turn to the effect on travel times caused by diversions for the Toronto International Film Festival (TIFF) on both King and Queen Streets. Part III will review service capacity actually provided at various points along the King route.

This will be the last article in which I conduct a detailed review of the “pilot” operation unless there is a significant change to warrant returning to the issue. It is clear after two years that the improvement in service on King Street is permanent and stable.

TIFF is quite another matter, and its effect on both King and Queen Streets is quite severe, particularly on the opening two days. This is an issue for a policy decision by Council on whether the economic benefit of closing the street completely on weekdays outweighs the effect on transit services and riders.

Service on the central part of King Street consists of two primary routes, branches of the 504 King car, supplemented by two other part-time services:

  • 504A King between Dundas West Station and Distillery Loop
  • 504B King between Dufferin Loop and Broadview Station
  • Effective September 2019, the new 508 Lake Shore tripper was added with five trips in the peak direction between Long Branch and downtown via King. This only affects service capacity charts which will appear in Part III.
  • The 503 Kingston Road route (operating with buses) has been consolidated with 502 Downtowner for the duration of the reconstruction project at Kingston Road and Queen Street. This route operates only during weekday daytime, and it is not included in the analysis because it does not operate across the full width of the “pilot” area.

These charts contain the same data as in previous articles up to March 31, 2019, and data for the six months to September 30, 2019 have been added.

To view any chart at a larger size, click on it. Full chart sets are available as PDFs at the end of each section.

Travel Times Across the Pilot Area

These charts plot the 50th (median value) and 85th percentiles for travel times between Bathurst and Jarvis. In both cases the screenlines used are in the middle of the intersection so that the start and end times used are measured when vehicles crossed, not when they arrived at or departed from stops.

The vertical shaded areas refer to periods when service on King was affected:

  • Red: Toronto International Film Festival (TIFF, Early September Annually)
  • Purple: King service diverted via Queen for track work (Spring 2016)
  • Yellow: Queen service diverted via King for track work (Fall 2017)
  • Green: King Street Pilot begins. Transit Signal Priority (TSP) deactivated (November 2017)
  • Blue: TSP reactivated (July 2018)

As previously reported, the major effect of the new traffic arrangements on King is the reduction in the variability of travel times shown by lower 85th percentile values so that service was much less likely to be erratic.

TIFF produced a severe impact on travel times for streetcars. This shows up as a spike in the charts in early September 2019, and more detail of the effects appears in charts in Part II. The effect in 2019 was worse than in 2018 especially on TIFF’s opening day, Thursday, September 5.

Service Changes Coming to 506 Carlton in October 2019

With the shift to the larger low-floor streetcars, the TTC will begin schedule changes on Sunday October 13 (Thanksgiving weekend) for route 506 Carlton. In many periods of operation, the headways will widen in recognition of the capacity of the new cars, although the change will also bring a capacity increase.

The schedules are designed on the basis that most service will be provided by Flexitys, especially in the off-peak period. This could lead to problems such as those seen on other routes where CLRVs operate on headways designed for larger cars and are badly overloaded as a result. A lot depends on there being enough new cars to fully populate the route.

On the schedules, the only CLRVs remaining in operation will be the 506 Carlton trippers and 511 Bathurst (which is planned to start conversion late in 2019).

The TTC Service Standards set design capacities for vehicles which in theory dictate the level of service a route received. The standard is more generous for off-peak than for peak service.

Peak Off-Peak
CLRV 74 42
Flexity 130 70
Ratio Flexity:CLRV 1.76 1.67
Ratio CLRV:Flexity 0.57 0.60

If service were replaced purely on the basis of scheduled capacity, then there would be about 60% as many Flexitys/hour as on a schedule for CLRVs.

The new service design (click to enlarge, or retrieve PDF version) is shown below.

The change in AM peak and midday headways is from 5’40” (340 seconds, 10.6 cars/hour) to 7’50” (470 seconds, 7.7 cars/hour), a decrease in cars per hour to 72% of current service. This will be partly offset by the larger capacity of the new cars plus the benefit of trippers scheduled during the height of the peak period.

The change in PM peak headways is from 6’00” (360 seconds, 10 cars/hour) to 8’30” (510 seconds, 7.1 cars/hour), a decrease in cars/hour of to 71% of current service.

This change comes on top of wider headways introduced in August in an attempt to improve route reliability by giving streetcars more running time and longer terminal layovers in a bid to cut down on short turns.

The capacity goes up, but the service frequency worsens. This will almost certainly be compounded by the TTC’s inability to maintain even spacing of vehicles as they move across the route. Even though they might leave their terminals somewhat “on time”, this situation quickly deteriorates into bunches and gaps.

There is always a challenge when the TTC substitutes larger vehicles on a route and widens the headway. Laissez-faire route management that might work tolerably on shorter headways falls apart when headways are wider. If two vehicles nominally ten minutes apart actually operate as a pair, then there is a twenty minute gap and the service might as well not exist at all. Equally, the short-turn stats might look wonderful because both cars have time to reach their terminal, but riders see the same gap they would have if one of the cars short-turned.

The TTC has a huge challenge in this regard, but shows little sign of trying to fix the problem preferring to assume that more running time and longer layovers will do the trick.

The Last (Official) Trip of the ALRVs

Today the TTC officially retired the last of the ARLV (Articulated Light Rail Vehicle) fleet with 4204 and 4207 doing the honours running a 501 Queen shuttle between Russell Carhouse (east of Greenwood) and Wolseley Loop (at Bathurst Street).

In what has become a tradition with the TTC’s older cars, there was an emergency truck and a “pusher” CLRV whose job would be to push its partner ALRV back to the carhouse (or at least off of a main route) if something went wrong. 4117 shadowed 4204 while 4156 partnered 4207.

Nothing went amiss, and the ALRVs ran their three hours of service without incident. Indeed, 4207 did double duty making an early trip as part of the Labour Day Parade before making the first eastbound trip on the 501 ALRV shuttle from Bathurst Street.

Many people are posting photos from the day on Twitter and Facebook. Here are the best of my own.

TIFF 2019 To Demolish Downtown Transit Service, Again

Updated Aug. 22, 2019 at 8:05 pm: The TTC has advised that temporary stops for the diversions are still to be finalized. Also, there will be Paid Duty Officers to manage traffic at Spadina, York and Church Streets. Thanks to Stuart Green for the update.

The City of Toronto and TTC have announced various road closures and service diversions associated with the 2019 edition of the Toronto International Film Festival (TIFF).

As in past years, King Street will be completely closed to traffic including transit operations from University Avenue to Spadina Avenue. This will begin at 5 am on Thursday, September 5 and continue through to 5 am on Monday, September 9.

Additional ad hoc diversions might occur on both Monday and Tuesday, September 9-10, for “red carpet events” from 3:30 pm onward.

Service arrangements this year are somewhat different from 2018 because there is now the split 504A/504B King service and the soon-to-be-restored 508 Lake Shore.

The primary diversion for almost all services will be:

  • From King to Queen on Spadina, both ways
  • From King to Queen on York, northbound/westbound
  • From Queen to King on Church, southbound/eastbound

Riders wishing to transfer from the subway to an eastbound King car to Broadview Station or to the Distillery should do so at Queen, not at King, or they will have to walk from Yonge to Church from King Station. There will be no eastbound King cars at Osgoode Station. It is not yet confirmed whether the TTC will establish a stop at Queen and York for a walking transfer.

Riders wishing to transfer from the subway to a westbound King car must do so at King or Osgoode Stations. There will be no streetcar service at St. Andrew Station, although there will be plenty of King cars nearby at York Street. Whether a temporary stop will be created at King and York is still to be confirmed.

This service design will see ALL of the King Street services, both ways, operating northbound on York Street giving an extremely frequent service, not to mention the potential for a total bottleneck making the turns east and west at Queen Street.

504A Dundas West to Distillery Service

This service will be broken into two segments:

  • From the west, 504A cars to/from Dundas West will operate downtown via Spadina and Queen east to Church, then loop via Church, King and York.
  • From the east, 504A cars to/from the Distillery will loop downtown via King, York, Queen and Church.

504B Broadview Station Service

The Broadview Station service will use the same loop downtown as the 504A Distillery cars:

  • Westbound on King to York, then north to Queen, east to Church and south to King.

There will be no replacement bus service parallel to King as has been attempted in some past years. Anyone destined for the area between University and Spadina on King will have to walk in from the bounds of the closed area or south from Queen Street. This is of particular concern for anyone going to screenings at TIFF Bell Lightbox which will have no transit service during the diversions.

508 Lake Shore Service

The new 508 Lake Shore trippers will loop downtown via:

  • Eastbound via Spadina, Queen and Church
  • Returning westbound via Richmond and Victoria to Queen, then west to Spadina

304 Night Service

The 304 night cars will divert via Spadina, Queen, Church/York both ways.

A shuttle night bus will operate between Wolseley Loop and Parliament/King bypassing the TIFF district via Adelaide and Richmond Streets.

503 Kingston Road Bus

Not mentioned in the TTC’s announcement is the 503 bus service which consolidates the 502/503 Kingston Road services in September. These buses are supposed to loop via York, Richmond, and University to King including a layover point on York north of King. That area will be thick with streetcar service. It is ironic that the only service that will stop eastbound at St. Andrew Station will be the 503 bus on what is sure to be a “now and then” schedule.

I am a TIFF supporter as a member and donor, and have attended the festival for over three decades. That said, I am disgusted by the gorilla-like behaviour of TIFF in elbowing aside vital transit services on weekdays in Toronto.

These diversions produce severe effects on service not just downtown, but on parts of the King and Queen routes far from the TIFF district. Riders across the city suffer so that TIFF can have its street fair.

Every year we hear that “next year will be different”, but nothing happens.

From the TTC’s diversion announcement:

We encourage you to plan your trip in advance. We thank you for your patience during this important event benefitting Toronto’s economy and international reputation as a world-class city.

A “world class city” would figure out how to integrate its transit service into a major cultural festival.

Streetcar Network Changes Coming in September 2019

Several streetcar routes will be affected by construction, schedule changes and the continuing shift from CLRVs to the low-floor Flexitys effective September 1, 2019. I will publish the detailed service plans with my overview of all schedule changes taking effect on that date, but here is a preview of the route changes.

Kingston Road & Queen Construction

Two projects will block streetcar service from The Beach from September 1 until mid-November:

  • Watermain replacement
  • Special trackwork replacement at Kingston Road including Woodbine Loop

501 Queen Service

The 501 Queen route will be operated with several overlapping services:

  • Regular 501A Queen cars will operate between Humber Loop and Russell Carhouse.
  • Buses on 501R will operate between River Street and Neville Loop diverting via Woodbine, Lake Shore and Coxwell.
  • Service to Long Branch on 501L will be provided by low-floor cars running from Humber to Long Branch on ten-minute headways at all times.
  • Late evening service will run through from Long Branch to Russell Carhouse.

Tripper services will operate including the restoration of 508 Lake Shore:

  • Bus trippers on 501 Queen will operate westbound from Coxwell rather than from Kingston Road. In the PM peak, eastbound trippers will run through to Neville using the same diversion as the 501R.
  • Streetcar trippers will operate on 508 Lake Shore with five trippers in each peak period.
    • In the AM peak cars will follow the Queen route from Long Branch to Roncesvalles, then run east to Parliament via King Street. They will return to Roncesvalles Carhouse via Parliament and Carlton/College, a route used by Long Branch trippers years ago to provide supplementary westbound service on Carlton to the University of Toronto. Cars will leave Long Branch Loop between 6:40 and 8:10 am.
    • In the PM peak, the trippers will run east from Roncesvalles to Broadview via King, then loop via Broadview, Dundas and Parliament running west from King and Parliament to Long Branch. Cars will leave Church Street westbound between 4:20 and 5:40 pm.

Overnight service on 301 Queen will terminate at Russell Carhouse, and it will continue to operate on the recently-established 15 minute headway. A 301B bus shuttle will operate from Russell Carhouse east to Neville diverting around the construction zone.

502/503 Downtowner/Kingston Road

For the duration of this project, the 502 and 503 services will be consolidated as 503 Kingston Road, and this route will operate from Bingham Loop to York Street. There will be no 502 bus service to McCaul Loop.

Service will divert around the construction site via Dundas and Coxwell both ways.

The downtown loop will be changed from the usual 503 arrangement. Buses will not operate on Wellington, but will continue on King to York Street. They will then turn north on York to Richmond, west to University and south to King Street. The layover point will be on York Street north of King.

22/322 Coxwell

During weekday daytime, the 22B Coxwell service will use Coxwell-Queen Loop rather than the longer route via Eastern Avenue which will be blocked by construction.

Evening and weekend service on the 22A and 322 services to Victoria Park will divert both ways via Dundas Street but will loop south to Queen via Coxwell-Queen Loop.

512 St. Clair

With the addition of low-floor service to Long Branch operating from Roncesvalles Carhouse, the 512 St. Clair route will move back to Leslie Barns. The carhouse routing will be via Queen, King and Bathurst, and cars will operate with pantographs up over these trips. This will mark the first scheduled pantograph operation over portions of these streets.

The operator relief point will be moved east from Lansdowne to St. Clair Station.

Carhouse Allocations

The routes and vehicles will be allocated to carhouses as shown below. Note that these are the scheduled service numbers, not the total fleet including spares.

Current plans are to begin conversion of 506 Carlton to Flexity operation later in the fall, but the details of this have not yet been published.

Zero Short Turns Does Not Equal Better Service

For many years, the TTC has had a fetish for reducing short turns, or more accurately, for reducing short turn counts. Together with “on time” stats, this is a primary metric for TTC management, the one they get gold stars for.

When former CEO Andy Byford hired the current CEO Rick Leary, one of his first tasks was to reduce short turns. The result is that the CEO’s report concentrates on two factors to the exclusion of all other measures of service quality.

Here are two pages from the June CEO’s Report for streetcars. There are similar pages for the bus network.

In a recent newsletter to constituents, Councillor Brad Bradford, also a member of the TTC Board, included the following chart to show how the TTC is attacking the short turn problem. Short turns on 501 Queen were the lowest in number among all streetcar routes in early April, and fell to zero on Monday April 15 (along with a big drop on other routes too). This looks good, but as we will see later, has unintended side effects.

Bradford’s newsletter included this text:

We all know the frustration of too many short-turning streetcars, especially during rush hour.  As a member of the TTC Board I’ve been working hard with my colleagues to improve the streetcar service and reduce the number of short-turns.  I’m happy to report that April 2019 had the lowest number of short-turns since 2014, including the 501 streetcar which had ZERO short turns for several days.

Short turns disproportionately affect Bradford’s constituents as they live at the eastern end of the 501 Queen and 506 Carlton routes. However, irregular service which I have documented in numerous articles affects riders along the entire route. Gaps of 15 minutes or more in what is advertised as “frequent service” do not encourage ridership, and the unpredictability of service leaves many people walking or taking alternate modes to the TTC.

Measures of Service Quality

The count of short turns only tells us how many cars did not reach a terminal over the course of the day. It does not tell us:

  • What proportion of the service this count represents. The scheduled service to Neville over the course of a day (6 am to midnight) is about 200 trips with a similar count at Humber. 40 short turns represent about 10% of service assuming they are equally divided between the two terminals.
  • What time(s) of day were most affected. Certain times of the day are disproportionately affected by short turns, notably the hours immediately after the am and pm peaks, and through the evening especially on busy nights in the club district downtown.
  • Whether the short turn was successful in restoring more regular service, otherwise known as “filling the gap” on its next trip. There appears to be little or no management of cars re-entering service from short turns, and they may well reappear immediately ahead of or, even worse, behind a “through” car without reducing the headway. The average headway looks better, but it’s a bunch of two cars with a wide gap, not evenly-spaced service.

Unless one sees a breakdown such as the one published by Councillor Bradford, the numbers in the CEO report are accumulated for all routes over all periods of operation including weekends. This is a very generic average value, and it gives only the most general idea of short turning as a trend, rather than pinpointing problem routes and times of the day.

The other published metric is the “on time departure”. This is something of a misnomer because “on time” is defined as a window from one minute early to five minutes late, in other words six minutes’ grace relative to the schedule. For a route with a five minute scheduled service, three cars could depart close together and be “on time” for the stats.

The TTC does not report on headway reliability and bunching, issues which are at least as important as short turns. A rider on a Queen car bound for, say, Dufferin Street from Yonge does not care if their car gets short turned at Sunnyside, but they do care if no car shows up for 15 minutes or more, and they cannot board the first one in the parade.

If the scheduled times were 12:00, 12:05 and 12:10, the actual departures could be 12:05, 12:07 and 12:09 and fit within their allowed windows. The service is supposed to look like this:

X————X————X————X————X————X————X————X————X————X

But it can look like this and still be “on time”:

—————X—X—X——————————X—X—X——————————X—X—X——————

It would not take long for cars to bunch together as triplets running across the route. However, the on time measurement only applies at the terminals, and what happens after vehicles leave is not reported.

The TTC produced route-by-route statictics for five months, April to August 2018, but they have been missing-in-action ever since.

An important metric is the distribution of headways by time of day. Charts showing this information are published regularly on this site. (See this article about headways at Neville Loop and scroll down to charts showing the range of headways actually operated.)

The TTC would do well to report on the proportion of headways that are less than 50% of the scheduled value, or more than 50% over that value, broken out by by time of day and by location. Situations where vehicles are running very close together (except for the few routes and periods where the scheduled service really is that frequent) should be flagged. This is not a particularly challenging exercise, but potentially quite embarrassing.

As a quick check, I looked at 501 Queen westbound at Yonge on Wednesday May 1. Of the 215 trips crossing Yonge Street, 54 were on a headway of two minutes or less, or one quarter of the service. There were 25 trips on headways ranging from 10 up to 18 minutes, over 10% of the service. Those are all-day values, and the proportions vary by time period. (The eastbound stats are comparable.) Here is a chart of the day’s data. Note that the trend line sits at about 5 minutes for much of the day only slightly above the scheduled headway, but what riders experience is wide gaps followed by at least two cars.

(For those who might argue that this is the fault of a mix of new and old vehicles, 501 Queen and just about every other route in the system has looked like this for years.)

Although there will be more data to digest, the TTC would have a better idea of just what riders face. Exception reporting would quickly flag areas of concern, although from my own experience looking at these data, there would be a lot of “exceptions” until the TTC addresses the problem of service reliability, not just of “on time performance”.

Crowding statistics are produced from time to time, but these rarely are broken down in public reports. This should be a standard part of the CEO’s report. If the TTC does not identify when its service is overcrowded, how can the public or the politicians with responsibility for transit funding and oversight reconcile claimed service provision with rider experiences?

Crowding and headway reliability are linked in that uneven headways lead to crowded vehicles (the “gap” car) and underused capacity. The average load might look good, but the average experience is not. Most riders are on the crowded vehicles and the “average rider” will report an overcrowded trip not to mention the possibility that they boarded the first vehicle to show up with difficulty, if at all.

Vehicle reliability is reported on an overall basis, not for its effect on service. Once a failure causes a delay of five minutes or more, it “counts”, but there is no distinction about the severity of the delay or the actions taken to restore normal service. Delays caused by infrastructure issues or by external events, and again the actions taken to counter their effects, are not reported. There is no metric for how well or poorly service was managed when things went wrong.

TTC Service Changes Effective June 23, 2019

The TTC will make several changes in its service on June 23. Many of these are the usual summer service reductions, but others will see changes for construction projects, to improve reliability on some routes, and to redeploy the streetcar fleet.

Subway

On 1 Yonge-University-Spadina, the dispatching of trains will change to increase the use of the north hostler track and exit from Wilson Yard (all days), and to restore the full capacity of Davisville Yard following expansion of the carhouse (weekdays).

On 2 Bloor-Danforth, a gap train will be dispatched from Greenwood or Keele Yard in the AM and PM peak as needed to fill service gaps. There will also be the usual summer service reduction on this line.

On both routes, crew procedures at Finch, Vaughan, Kipling and Kennedy will be changed to single step-back operation.

Streetcars

The 501 Queen car will be formally scheduled as a low-floor route entirely with new cars. In recognition of their larger capacity, headways will be widened somewhat, but not on the scale Toronto saw when the two-section ALRVs replaced the CLRVs on a 2:3 ratio with correspondingly wider headways. Although in theory the scheduled capacity remains the same, the actual capacity could fall because new larger cars have already been operating on the shorter CLRV headways. I will explore this in a separate article.

Night service will be improved on 301 Queen to reduce overnight storage needs with the large number of new cars now on the property together with remnants of the old fleet, and the partial closure of Roncesvalles Carhouse for reconstruction. This continues a change introduced on 304 King in May.

CLRVs will continue to operate on the Long Branch segment of the route. This is expected to change to low-floor operation in September. The peak period trippers that run through from Long Branch to/from downtown will be dropped, but will return in the September schedules.

The 511 Bathurst route will revert to streetcar operation. The exact mix of cars will depend on availability and day-to-day decisions about allocation. The service memo shows a small allocation of ALRVs to the route, but these could turn out to be Flexitys instead just as happened on 501 Queen. (Click to expand the table below.)

Leslie & Eglinton

For the summer months, Leslie Street will be closed at Eglinton, and a temporary loop will be created north of the intersection. This will be used by 51 Leslie and by some of the 54 Lawrence East service. Weekdays from 5:15 am to 9 pm, and weekends from 8 am to 7 pm, the Starspray and Orton Park branches will terminate at the Leslie/Eglinton loop, and there will be a separate service running from Eglinton Station to Lawrence East Station via Don Mills & Eglinton. Outside of these periods, the Starspray and Orton Park services will run to Eglinton Station via Don Mills, and a supplementary shuttle will run from Leslie/Eglinton to Lawrence/Don Mills as part of the 51 Leslie route.

All 51 Leslie service will terminate at Leslie/Eglinton.

The 954 Lawrence East Express is not affected.

Service on 34C Eglinton East to Flemingdon Park will be increased slightly to offset changes to 54 Lawrence East.

See the linked spreadsheet for details of the various routes, headways and hours of service.

Lawrence Station

Because of construction at Lawrence Station, part of the bus loop will be closed for paving and the 52/952 Lawrence services will loop via the east side of the station. Service on 124 Sunnybrook and 162 Lawrence-Donway will be extended west and north to Roe Loop on Avenue Road. Transfers between these routes will move to surface stops.

Wellesley Station

Construction at Wellesley Station will complete and the 94 Wellesley will return to its normal operation with its eastern branch terminating there rather than at Queen’s Park.

Royal York Station

Buses were planned to return to Royal York Station on May 24, but the schedules will not formally be revised until August. Interlining of 15 Evans with 48 Rathburn, and of 73 Royal York and 76 Royal York South, will continue until then.

Bay Bus

Service on the 6B short turn at Bloor will be discontinued during the peak period and all buses will run north to Dupont.

Dufferin Bus

All service will terminate at Dufferin Loop rather than at Princes Gates due to frequent summer events that make bus operation through Exhibition Place difficult.

Road Construction in Scarborough

Several routes will be affected by road construction projects.

Danforth Road from St. Clair to Danforth Avenue:

  • 113 Danforth

Midland Avenue from Danforth to Lawrence:

  • 20 Cliffside
  • 57 Midland

Brimley Road from Progress to Huntingwood:

  • 21 Brimley

Huntingwood Drive from Kennedy to Brimley:

  • 169B Huntingwood

20190623 Service Changes

Analysis of 501 Queen: Why Are Trips Taking Longer?

Schedule changes for 501 Queen pending on June 23 are, in part, related to a growth in travel times. This article examines the evolution of the route’s operation and travel times over the past year.

There are a lot of charts in this post in part to show many aspects of the discussion and in part so that readers can refer to different parts of the route of interest. All charts are clickable to open a larger version.

Previous articles in this series are:

The growth in 501 Queen travel times from 2018 to 2019 is summarized in the following chart of monthly averages across the route westbound.

This prompted theories both by readers and by me about possible causes including:

  • Longer dwell times caused by new streetcars
  • Greater congestion caused by changes in traffic signal timing

The charts below, included in a previous article, compare average travel times by hour in each direction and show slightly longer averages for Flexitys compared to CLRVs. A valid question here is whether the CLRV times are artificially higher because they catch up to Flexitys and then travel at a lower speed than would otherwise happen. This is difficult to verify because there is already much bunching leaving Neville and Humber Loops, and “gap cars” (the first car in a parade) slows following vehicles regardless of which type it is. However, a detailed review of the headways in front of each type of car shows that in many cases Flexitys tend to be carrying wider gaps. This is not, however, consistently the case.

As to the concern about signal timing, a factor that affected the King Street Pilot for part of its run, this did not pan out for the route as a whole, but was a factor at one location. City staff advised that the only place that was changed was at the Queen/Lansdowne/Jameson intersection where work is underway, and transit signal priority has been shut off. Elsewhere, the signal timings were not modified.

A further question lies in a jump in travel times midway through April. Both the CLRV and Flexity travel times went up and also became more varied from day to day in weeks 3 and 4 of April. This implies some change affecting the route overall, not just one vehicle type. A review of detailed data showed:

  • The proportion of service provided by Flexitys did not change in the second half of April. Any effects due to their operating characteristics should be the same throughout the month.
  • An unknown activity between Sherbourne and Jarvis slowed traffic during the late morning hours of the last two weeks in April. Some other congested locations such as the Lansdowne/Jameson and Bay-to-York areas also worsened during this period.
  • The TTC instituted one of its periodic “no short turn” policies start in mid-April. While this makes the management statistics look good, the effect is to create larger gaps which, in turn, drive up average travel times as packs of cars follow each other and gaps are not filled.

Total trip times can be affected by extra dwell time at stops, by slower operating speeds, or by a combination of the two. In reviewing the data for April in both 2018 and 2019, I found that changes in speed were more marked than changes in dwell times.

Of particular note is that some of the areas where streetcars go slower in 2019 are areas of bad track where slow orders have been implemented. The number of these locations is growing on the streetcar network, and there is reason to worry that the TTC is not keeping ahead of this problem. Most notable is the track at Queen/King/Roncesvalles including the carhouse entrance and Sunnyside Loop. This has been on the books for replacement for a few years, and that work was delayed yet again to 2020 due to problems at the City with planning and contracting for the work. However, this is not the only place on the route where slow orders are a quick fix for track that needs repair. The TTC has a generic “go slow” policy for all intersections which slows streetcar service across the system.

I will update this tracking with May and June 2019 data as they become available.

In the next article in this series, I will review operations on 501 Queen during the period when there appears to have been an embargo on short turns.
