Toronto’s Transit Capacity Crisis

In recent days, Mayor Tory has announced, twice, a ten point program to address crowding on the TTC. The effectiveness of this program is limited by years of bad political decisions, and the hole Toronto has dug itself into is not one from which it will quickly escape.

This article is a compendium of information about the three major portions of the “conventional” (non-Wheel-Trans) system: subway, bus and streetcar. Some of this material has appeared in other articles, but the intent here is to pull current information for the entire system together.

Amendment February 15, 2018 at 5:30 pm: This article has been modified in respect to SmartTrack costs to reflect the fact that over half of the cost shown as “SmartTrack” in the City Manager’s budget presentation is actually due to the Eglinton West LRT extension which replaced the proposed ST service to the commercial district south of the airport. A report on SmartTrack station costs will come to City Council in April 2018. Eglinton LRT costs will take a bit longer because Council has asked staff to look at other options for this route, notably undergrounding some or all of it.

TTC Board Meeting February 15, 2018

The TTC Board will meet on February 15, 2018. Among the items on the agenda are:

Scarborough Subway Extension (SSE)

The SSE itself is not on the agenda, but it has been the subject of much recent debate over when the projected cost and schedule for the extension will be released.

In the November 2017 CEO’s Report, the project scorecard included a schedule showing that 30% design would be complete in the second quarter of 2018, and an RFP [Request for Proposals] would be issued in the third quarter. Even when this report came out, former CEO Andy Byford was hedging his bets about a spring 2018 date saying that more work would be needed to verify and finalize the figures. A key note in this scorecard states:

EFC [Estimated Final Cost] was approved in 2013 based on 0% design. With the alignment/bus terminal now confirmed by City Council, the project budget and schedule will be confirmed as design is developed to the 30% stage, factoring in delivery strategy and risk. The performance scorecard will continue to report relative to the project’s original scope, budget and schedule, as approved by Council in 2013, until the project is rebaselined at the 30% stage in late 2018.

In other words, neither the schedule nor the projected cost reflected the evolving and expanding design of this project.

Jennifer Pagliaro in the Star wrote about the result of a Freedom of Information Request that revealed a briefing to Mayor Tory in September 2017. That briefing included a statement that the cost estimate for a Stage 3, 30% design, would be available in September 2018.

Because Council will not meet until 2019, numbers that might have been available before the election would not be released until after the new Council takes office. After the story appeared, City staff replied:

The cost information referenced in page 9 of the October TTC briefing deck refers to the planned timing for initial cost inputs from TTC engineering staff. These are not the full cost estimates necessary for consideration by Council. Further work will be required to appropriately account for financing, procurement model, market assessment and other critical factors. The final cost estimate, subject to the variability ranges noted below, will include these inputs.

This additional work will be undertaken by various TTC staff as well as city officials from corporate finance, financial planning, city planning and other divisions. [Tweet from Jennifer Pagliaro, February 7, 2018]

I wrote to the TTC’s Brad Ross about this conflicting information, and particularly about the question of how an RFP could be issued in 3Q18 when Council would not be approving that the project pass beyond “stage gate 3” until 2019. He replied:

No RFP will be issued until after Council approval. You will note in the Key Issues and Risks section of the scorecard from November reads, “The performance scorecard will continue to report relative to the project’s original scope, budget and schedule, as approved by Council in 2013, until the project is rebaselined at the 30% stage in late 2018.”

To be consistent with the report to Council in March 2017, only the revenue service date was revised in the scorecard (from Q4 2023 to Q2 2026). The TTC recognizes and acknowledges that this has led to confusion. The TTC will be taking steps to ensure greater clarity in its next CEO Report in March 2018. [Email of February 9, 2018]

The February CEO’s report states:

Work continues to progress design towards Stage Gate 3, expected in fall of 2018. At this time, the project will provide initial cost inputs from the TTC team (includes detailed costs for the Scarborough Centre station, tunnel, Kennedy station, systems, property and utilities). Further work is underway by the new Chief Project Manager with key stakeholders within TTC and the City to define the activities, approval process and timelines to arrive at the final Class 3 Cost Estimate, Level 3 Project Schedule, and associated Risk Analysis.

As requested by City Council, a report will be presented at the first opportunity to the Executive Committee, TTC Board and City Council, which is expected to be Q1 of 2019. [pp 15-16]

The debate, as it now stands, is about releasing whatever material will be available in September 2018 so that it can inform the election debates. Additional costs as cited by the city would sit on top of the September numbers, but at least voters and politicians would know whether the SSE’s cost has gone up just for the basic construction, let alone factors related to financing and procurement that would be added later.

Meanwhile, SSE promoter Councillor Glenn De Baeremaeker speaking on CBC’s Metro Morning said:

I don’t think it matters what the costs are.

This has been taken to read that money is no object, and that well may be the political reality in Scarborough – there is no way the many politicians who have so deeply committed to the subway project can back out. De Baeremaeker continued:

Whether the costs go up or the costs go down, people who have tried to sabotage the subway and stop the subway, will continue to try to sabotage it, they’ll continue to try to stop it, and they will never vote for it. So I would challenge the Councillors who say “I want to see the cost”. My response is and if it’s a reasonable cost, will you support the subway? Well, no. [At 3:26 in the linked clip]

What De Baeremaeker does not address is whether he has an upper limit beyond which even his enthusiasm might be dimmed. Also, on the question of a “reasonable cost”, what has been lost here is the fact that the subway “deal” was sold on the basis that the $3.5 billion included the Eglinton LRT extension to UTSC Campus. What had been a $2 billion-plus subway when it was approved as a compromise by Council, quickly grew to $3 billion-plus, and the LRT extension is left to find alternate funding. One could reasonably ask whether the LRT was ever really part of the deal, or was simply there as a sweetener that pulled in wavering supporters who now see just how gullible they were.

A related issue that has not yet surfaced is the question of whether building the SSE for a 2026 opening will require concurrent changes in timing and/or scope for the planned renewal of the Bloor-Danforth subway including a new signalling system and fleet. A report on the renewal is expected in April 2018, although this date has changed a few times over past months. The TTC/City capital budget and ten year plan do not reflect this project, at least with respect to timing, and probably with respect to total cost.

TTC Service Changes Effective Sunday, February 18, 2018

Changes are coming to TTC routes in February with the most significant being on the streetcar network. I provided an overview of the streetcar changes in a previous article, but the details of headways and running times are in the spreadsheet linked below.

On the bus network, there are several tweaks to running times and headways.

Extra running time for Metrolinx construction projects will be provided on 36 Finch West, 63 Ossington and 71 Runnymede.

Evening service on the 12 Kingston Road bus will be modified so that trips after 10:30 pm on weekdays and 5:30 pm on weekends run via the 12B routing along Kingston Road instead of dodging north to serve Variety Village.

Service on 121 Fort York-Esplanade will lose one bus during weekdays all day except the AM peak, and weekend evenings. This route has chronically erratic service that affects demand, but that is not addressed in the change.

Minor service cuts and/or running time adjustments will widen headways on:

  • 17 Birchmount (AM peak)
  • 37 Islington (Midday weekdays)
  • 40 Junction (Saturday morning)
  • 79 Scarlett Road (PM peak)
  • 111 East Mall (AM peak and midday)

Minor improvements and/or running time adjustments will shorten headways on:

  • 40 Junction (Sunday afternoon)
  • 42 Cummer (Weekdays)
  • 102 Markham Road (AM peak)

On 1 Yonge-University, all crew change will now occur at Wilson Station rather than being split between Wilson and Eglinton Stations due to pending construction at the latter.

Streetcar Service Updated Effective February 18, 2018 (Updated)

Updated February 8, 2018: The TTC has announced details of changes to bus and streetcar services on the west end of the 501 Queen route. This information has been added below in the section on that route.

The February 2018 schedules will bring major changes to the streetcar system. I will include these in a coming article with all of the details for the new schedules, but with the scope of the streetcar changes and the interest in this topic, here is a wrap-up of what is planned for these routes.

King Street Corridor

The current schedule calls for trippers to operate, primarily buses and in the AM peak, over the entire 504 King route. These will be replaced with four ALRVs (articulated streetcars) operating from Sunnyside Loop to Broadview. As actually operated, the AM trippers are already using CLRVs (regular sized streetcars) swapped from the 505 Dundas route. Four more ALRVs will be used as standby “run as directed” cars to supplement service on King as needed.

January Schedule January Actual February Schedule
AM Peak
CLRV 33 33 33
CLRV Tripper 7
ALRV Tripper 4
ALRV Run as Directed 4
Bus Tripper 7
PM Peak
CLRV 33 33 33
CLRV Tripper 2
ALRV Tripper 1 1 4
ALRV Run as Directed 4
Bus Tripper 2

The tripper schedules have been changed so that they better cover the peak periods.

  • Eastbound trips leave Sunnyside Loop at: 7:41 a.m., 7:57 a.m., 8:12 a.m., 8:27 a.m., 9:10 a.m., 9:27 a.m., 9:42 a.m., 9:56 a.m.
  • Westbound trips leave Broadview & Queen at 3:07 p.m., 3:20 p.m., 3:33 p.m., 3:46 p.m., 4:50 p.m., 5:03 p.m., 5:16 p.m., 5:29 p.m.

The 503 Kingston Road Bus which now operates from Bingham Loop to York & Wellington during peak hours only will be replaced by a streetcar with service on weekdays peak and midday. This will replace the 502 Downtowner bus which changes to peak-only operation.

During the peak periods the 12′ headway of buses will be replaced by a 12′ headway of CLRVs on the 503 service, and it will be extended west to loop via Spadina, Adelaide and Charlotte Streets. Midday service will operate every 9′ replacing the existing 10′ service on the 502 Downtowner bus. This removes 6 buses/hour from Queen Street, and adds not quite 7 cars/hour to the section of King east of Spadina.

According to the TTC, track construction is planned on Wellington east of Yonge in May. It is not clear whether, when this is complete, the 503 will revert to its usual York street terminus as this would remove the added service between York and Spadina. Whether the Wellington Street work actually occurs remains to be seen as there were plans to defer this until 2019 to avoid complications with the King Street Pilot. The track recently became operational with the restoration of overhead on the one missing section between Church and Yonge westbound.

Service on 514 Cherry during the midday and early evening will be improved from every 15′ to every 10′ to provide added capacity on the King corridor. On Sundays from 10:00 am to 7:00 pm, service will improve from every 15′ to every 11′. (The 514 Cherry route is notorious for irregular headways at its terminals and so the scheduled headways may not match actual experience. This will be the subject of a separate article.)

In combination, these changes will increase the level of service on King Street with the effect concentrated downtown. In particular, there is little AM peak relief for riders inbound from Parkdale, Liberty Village and Bathurst/Niagara beyond a change in the timing of the trippers, whatever benefits the “run as directed” cars might provide and the gradual replacement of runs now operated with CLRVs by the new Flexitys as they become available.

501 Queen & 502/503 Kingston Road

As noted above, the 502 Downtowner midday bus service from Kingston Road to Queen & University will be replaced by the 503 Kingston Road streetcar operating to Spadina & King. Peak service on the 502 bus is not changed, and peak 503 streetcar service will operate at the same frequency, every 12′, as the former bus service. Midday service on the 503 streetcar will be slightly better at 9′ than the 10′ headway now on the 502 bus.

The 501 Queen schedules were written on the basis that Humber Loop would re-open, but work there will not be completed until later in the spring. The planned service would have seen 501 Queen cars operating from Neville to Humber with the 501L Queen bus running from Long Branch to Windermere. Pending the completion of Humber Loop, the streetcars will turn back at Sunnyside Loop, and the 501L buses will operate east to Roncesvalles. 501L buses will no longer run east and south to Dufferin Loop.

The looping and transfer arrangements for the 501L bus at Roncesvalles, and later at Windermere, have not yet been announced.

When 501 Queen streetcar service to Humber Loop resumes, the last service stop will be at South Kingsway because there will be no connecting services at Humber.

The 501M bus service via Marine Parade will be dropped because of low use. The 66 Prince Edward bus is available as an alternative, and it will continue on its diversion routing.

The 301 Queen night service is unchanged with two branches continuing to operate from Neville to Sunnyside (streetcars) and from Dufferin Loop to Long Branch (buses). This will be modified with the April schedules (details not yet announced).

Service on 501 Queen streetcar will be scheduled to operate with a mix of CLRVs and ALRVs on a more frequent headway than the current schedules that presume all ALRVs and their capacity. This has been a long-standing problem for Queen street where smaller cars attempt to handle demand on a service designed for larger vehicles. The improvement is about a 10% increase in cars/hour in the peak, and a 20% improvement off-peak.

Updated February 8, 2018

The planned changes to routes on the west end of Queen is different from that originally described in the service change memo. The following information is taken from the TTC Service Advisory page.

Effective February 18:

  • Streetcars will operate between Roncesvalles and Neville as originally planned.
  • 501L buses will operate between Long Branch and Dufferin/Queen looping via Gladstone, Peel and Dufferin instead of running south to Dufferin Loop as they do now.
  • 301L night buses will continue to run between Long Branch and Dufferin Loop.
  • The 501M Marine Parade shuttle will be discontinued as originally planned.

Effective April 1:

  • Streetcars will operate between Humber and Neville. However, Humber Loop will not be ready to reopen as a transfer point with bus routes, and so the connection to the 501L service will be at Windermere (if the information in the service memo still holds).

Effective early June:

  • Streetcars will return to the full route from Long Branch to Neville.

Work now underway at Humber Loop includes:

  • new streetcar tracks including new spur track
  • accessible platforms
  • new/wider pedestrian tunnel walkway
  • new sub-station building and underground conduits for electric cables
  • realignment of all existing overhead wiring in the loop and in the tunnel leading to Lake Shore Boulevard West

According to the TTC notice:

Track installation and some overhead adjustments for the Queen turn-back will completed by April 1, 2018, weather permitting. Remaining work, including passenger platform renewal, track renewal and overhead adjustments for the Lake Shore turn-back, as well as a wider pedestrian tunnel walkway will be completed by early June 2018.

506 Carlton & 505 Dundas

Service on both the 506 Carlton and 505 Dundas routes will be converted to bus operation. In addition to the streetcar shortage, several construction projects will affect these routes in coming months:

  • Track construction on Broadview from south of Dundas to Hogarth (north end of Riverdale Park) beginning in May
  • Track construction at Parliament/Gerrard in May
  • Track construction at Broadview/Dundas and Broadview/Gerrard in the summer
  • Track constuction at Dundas/Lansdowne in September
  • Water main construction on Dundas from Bathurst to Huron in September
  • Main Street Station construction through the summer

506 Carlton buses will run to Keele Station as their western terminus rather than to High Park Loop.

The bus replacements for streetcar service vary in the ratio of buses to streetcars depending on the time of day.

Dundas Streetcar Dundas Bus Carlton Streetcar Carlton Bus
AM Peak 18 27 32 45
M-F Midday 18 27 28 36

Night Service 3 3

511 Bathurst

The 511 Bathurst route will revert from bus to streetcar operation using CLRVs. All service will operate between Bathurst Station and Exhibition Loop.

Service on weekdays will generally be less frequent with the streetcars than the buses reflecting their larger capacity, although peak service south of King and west to Exhibition will improve with the elimination of the short turn 511C bus service.

Weekend streetcar schedules are the same as those used in November 2015. Saturday daytime service will be at similar headways with the streetcars as with buses reflecting demand at those hours. Sunday afternoon and early evening service will be slightly less frequent with the streetcars.

509 Harbourfront, 510 Spadina and 512 St. Clair

There are no changes to the schedules for these routes.

Roncesvalles Carhouse

This carhouse will close until late 2018 for construction in the yard. Service will be operated from the east end carhouses as below:

  • Leslie: 509 Harbourfront, 510/310 Spadina, 514 Cherry
  • Russell: 501/301 Queen, 503 Kingston Rd., 504 King, 511 Bathurst, 512 St. Clair

The King Street Pilot: Sorting Fact From Fiction (Part IV: Headway Reliability)

The King Street Pilot has been a success in reducing travel times for streetcars through the core area with knock-on benefits to the outer parts of the route in reduced short turns and more reliable service especially outside of the peak period.

Headway (the space between vehicles measured in time, not distance) is a big issue for riders, and it also affects crowding levels.

If a service is scheduled to show up every 4 minutes, and actually does so, then on average each car will have a similar load (subject to surges that will upset this), and riders can expect an average waiting time of half a headway. Even if they just miss a car, they know fairly certainly that the next one will be along soon, and it might even be in sight.

A chronic problem on all transit services is the bunching of vehicles that can yield two (or more) cars or buses close together followed by a long gap. When cars bunch, riders inevitably pack onto the first one. This is not simply a lemming-like desire to rush the first car, but the effect of years of experience telling riders than when there is a bunch, some of the cars will be short turned. If they are on the first one, they can at least drop back one car when this happens. If they are on the second or third in the parade, they may get dumped off and face the next big gap.

Some transit systems implement time points along a route where vehicles will hold for a scheduled departure time. A more sophisticated version of this is to hold in order to space out service regardless of the schedule. Riders do not care if a car (and its driver) are “on time”, only that the headway is close to the advertised value. It is the transit system’s problem to sort out operator crewing with schedules that can be achieved most of the time, but which are not excessively padded to the point service dawdles along a street. The latter has been a problem on some TTC routes where extra running time overshot the mark leading to annoyingly slow service and congestion at terminals where vehicles arrive early.

With the removal of much of the downtown congestion, and hence the variability in travel times for that part of the route, there was hope that headway reliability would improve. Results to date leave a great deal to be desired. There has been some reduction in the most annoying of wide gaps, but bunching remains a problem.

To be fair, when the scheduled headway is under 4 minutes, some bunching is inevitable. Even if cars leave the termini like clockwork, demands at stops vary as does the traffic enroute, and cars will get slightly off schedule. The follower will catch up, in part because of the lighter load from its shorter headway.

The TTC has a service quality target that all vehicles will leave their termini no more than 1 minute early or up to 5 minutes late. This is the only point on the route where schedule reliability is measured. (Until early 2015, the value was measured at several points along the route to provide a blended score, but this practice was dropped.) There are three basic problems with this scheme:

  • A terminus is the simplest place to monitor and dispatch service, and headway variations should always be the lowest at these points.
  • When the scheduled headway is small, the allowed 6-minute window for being “on time” permits vehicles to depart in bunches and still be “on time” because they remain within the allowed variation.
    • A perfect four minute headway would depart a terminal at 0, 4, 8, 12, 16, 20, 24 … minutes past the hour.
    • The same vehicles operating in pairs at 0, 7, 8, 15, 16, 23, 24 … would be “on time” because the alternate cars in the sequence are only three minutes late.
    • This problem is worse for wider scheduled headway because until the “five minutes late” line is crossed, the service is on time.
      • 0, 6, 12, 18, 24, 30, 36 … and 0, 11, 12, 23, 24, 35, 36 … are both “on time” but the latter actually provides a 12 minute headway of vehicles in pairs.

The TTC has, in effect, constructed a target for “on time performance” that considers bunched service to be acceptable even at a terminal. The problem with this is that as vehicles move along the route, the headway variations get bigger and bigger. It is ironic that even with this generous standard, actual service across the system does not achieve anywhere near the target on the streetcar or bus networks. The streetcar network itself went into a long slide through 2017 thanks to declining vehicle reliability and the proliferation of construction projects.

The King Street Pilot: Sorting Fact From Fiction (Part III: Service Capacity)

An important issue for the King Street Transit Priority pilot is the rising demand on that corridor. Previous TTC stats showed a total of 65,000 riders using the 504 King and 514 Cherry lines combined, but this has now been updated to 71,000 even before the pilot began. Further growth comes from riders attracted to the improved service, and the line is now crowded beyond capacity at some times and locations.

The TTC has announced “improvements” from time to time on the King route, but this masks declines in service capacity.

The service design for the am peak period uses a base service about every 4 minutes overlaid by peak “trippers” that bring the headway down to about 2 minutes. However, the number of trippers has fallen over the years and in practice, the “wave” of very frequent service now lasts only about half an hour. This comes eastbound on King at Dufferin 6:50 and 7:20 am, westbound at Broadview between 7:45 and 8:15 am, and eastbound again between 8:55 and 9:25 am.

There are now seven trippers where once there were sixteen, and for some time streetcars on the trippers were replaced by buses at a lower capacity. Recently, peak vehicles were swapped between 504 King and 505 Dundas so that the trippers could revert to streetcar operation.

When buses began operating on 504 King, the TTC claimed that this was a service improvement. This was true for a time when buses allowed the service to build back to its previous high point, but over time the number of bus trippers fell.

Using the TTC’s vehicle tracking data, one can plot the actual capacity operated at various points and times on King Street. These are actual, not scheduled, capacities, and they reflect the day-to-day fluctuations in service and vehicle types. For the purpose of the charts here, the Service Standards planning capacities are used. These are not the crush capacity of vehicles, but a target level in Board-approved TTC standards for an average level of crowding that should not overwhelm the service with loading delays and severely uncomfortable conditions. Whether the TTC actually achieves this is another matter, but the numbers give an indication of the relative levels of service operated over time.

The Service Standards for peak period vehicle capacity are:

  • Bus: 51
  • Standard streetcar (CLRV): 74
  • Two-section streetcar (ALRV): 108
  • New five-section streetcar (Flexity): 130

[Service Standards at p. 10]

Here is an example of one chart showing capacity eastbound at Bathurst & King between 7:00 and 8:00 am from January 2016 to December 2017 (note that February 2016 data are missing).

The capacity provided here was at its height in the spring and summer of 2017 when ALRVs normally used on 501 Queen were redeployed to 504 King. In fall 2017, service levels were reduced because of the change in vehicle type.

Noteworthy in this chart is the growth in capacity provided by Flexitys first on 514 Cherry (building up to full low-floor operation by mid 2017) and more recently with the addition of the new cars to 504 King. Although they do not make up half of the vehicles operating on King, they account for half of the capacity in the central section.

For a longer-range view of capacity, here is the same chart with data (where I have the details) going back to December 2006. This illustrates the long period during which the capacity provided on 504 King was static even as land along the route redeveloped. This is a chronic problem on the streetcar routes because an order for new cars and a larger fleet was delayed so long.

The sets of charts below illustrate capacities at five locations and times. Each set contains four charts covering the peak periods from 6-10 am and 3-7 pm depending on which period is illustrated.

Jameson AM Peak EB

Service eastbound at Jameson does not include the 514 Cherry cars which enter the route at Dufferin. Flexitys appear here only after their recent addition to 504 King. Note how the capacity provided here drops in the hour from 8-9 am compared to those on either side of it.

Bathurst AM Peak EB

Service eastbound at Bathurst includes the 514 Cherry cars and the growing contribution of Flexitys on this route is evident from June 2016 onward.

Yonge PM Peak WB

The PM peak service design is different from the AM in that there are few or no trippers (depending on which schedule one considers), and so this location has been less affected by cutbacks in that part of the service. However, service capacity has not changed much over the past two years especially during the peak 5-6 pm hour.

Bathurst PM Peak WB

The situation at Bathurst is similar to that at Yonge, although it can be affected by cars short-turning at Spadina. After the 503 service is added in February, the capacity at Yonge will be slightly higher than at Bathurst.

Jameson PM Peak WB

The capacity of service outbound west of Dufferin is, if anything, lower now than it was in past years. This reflects the concentration of service east of Dufferin with the coming of the 514 Cherry route.

In summary, riders who believe that service, as measured by capacity, has been better in the past are in many cases correct. An important part of the King Street Pilot will be to determine how much latent demand can be attracted to the route through the combination of lower travel and wait times, and greater route capacity.

The King Street Pilot: Sorting Fact From Fiction (Part II: Travel Times)

On the Torontoist, I wrote an article reviewing experience with the King Street Transit Pilot and some of the preliminary claims and reactions to it. This piece is the first of the technical follow-ups to that article with more detailed data about the behaviour of transit service on King.

Note that this analysis only covers the operation of transit vehicles, not of general traffic. For information on other data collected by the City of Toronto, please refer to the “data” page on the project’s site.

This article deals with travel times on various parts of the King route both inside and outside of the Bathurst-Jarvis pilot area. Following articles will address capacity and service reliability.

For a review of operations up to the end of November 2017, please see:

Averages versus Individual Data

In reporting the change in travel times, the City of Toronto cites averages, maxima and minima for the “before” and “after” conditions. For example, in the chart below, eastbound trips in the PM peak before the pilot ranged in length from 13.0 to 25.0 minutes with an average of 18.9.

However, the “before” numbers omit some of the worse cases for travel times:

  • The period of the Toronto International Film Festival from September 7-17, 2017. During early days of TIFF, service was diverted via Spadina, Queen and Church adding greatly to travel times. Even after King Street nominally reopened, service was interrupted from time to time with unannounced diversions.
  • The period of track construction at Queen and McCaul Streets from October 16-27, 2017. This period saw 501 Queen streetcars shift south to King adding turning movements at Church eastbound and Spadina westbound that took place generally without any transit priority. Some traffic spillover from Queen to adjacent streets occurred, but this was not measured.

Gray: Pre-pilot Pink: November Mauve: December

Although omission of these two periods puts the best possible light on the “before” conditions and avoids criticism that the project is making a worst/best case comparison, it is a fact of life that service and travel times on King are routinely affected by various projects including construction and special events. A valid test for the pilot will be the street’s operation during a Queen Street shutdown for an event at City Hall or at Much Music. How will transit service and other traffic behave when part of the downtown network is taken “offline”? This remains to be seen.

The averages are the most commonly cited data in the press and in political comments. However, these averages hide a great deal.

  • Travel times vary considerably from hour to hour, and from day to day.
  • A three-hour average over the peak period includes many trips that occur under less-than-peak conditions, and this pulls down the averages.
  • Averaging data for several weeks smooths out the effect of daily variation.
  • Averaging over the entire pilot area merges data from areas where the pilot’s effect is small with those where it is large.
  • Averaging over only the peak periods misses the benefits, if any, of the pilot for off-peak operations.

TTC Service Changes Effective January 7, 2018

There are few changes planned for the January 2018 schedules.

2018.01.07_Service_Changes

14 Glencairn is the latest of many routes to get additional running time compensating for the Crosstown LRT construction. Oddly, the end date shown for this change is December 2022 where all other Crosstown-related end dates are in 2021.

Supplementary service on 32 Eglinton West is being reorganized. There are currently several Service Relief buses operating from Mt. Dennis during most operating periods. These will be replaced by peak-only buses from various garages.

75 Sherbourne trips at the start and end of service are being changed to begin/end at Sherbourne Station rather than at South Drive in Rosedale.

The official route and stopping arrangements for various lines serving Finch West and Pioneer Village Stations have been clarified for periods when these stations are closed.

The TTC has already confirmed through the media that due to the late delivery of Flexitys from Bombardier, there will be bus substitutions on 505 Dundas and 506 Carlton starting with the February 18, 2018 schedules. This is also related to service reorganization to boost capacity on King Street. I will report the details when they are available.

(Bus trippers originally planned for 504 King are now actually operating on 505 Dundas replacing CLRVs that have been redirected to King Street for extra capacity.)

It should be noted that due to track construction on Broadview planned in 2018, there will be effects on the Carlton, Dundas and King routes that will probably last two schedule periods.

Analysis of Routes 501 Queen and 6 Bay: November 2017 (Part 2: Preliminary King Street Pilot Review)

This is the second article reviewing the effects of the pilot King Street transit priority scheme. Part 1 looked at the behaviour of the 504 King streetcar route, and Part 2 concerns the operation of 501 Queen and 6 Bay during the same period.

Among the effects anticipated from the pilot was an increase in traffic on parallel streets with the effect reaching as far north as Queen Street. Queen suffers badly during the shutdown of King for TIFF in September, and by extension some problems were expected to show up with the pilot’s changes changes on King.

Another effect that was expected was congestion on the north-south streets crossing King. Only one transit route in mixed traffic, 6 Bay, operates on such a street.

The City of Toronto is monitoring traffic behaviour on many streets in the study area and will publish their own preliminary findings in mid-December.

The charts presented here are in the same two formats as those in Part 1:

  • One pair of charts shows the travel times between Bathurst and Jarvis on Queen, and between Dundas and Front on Bay, both ways. Each day’s data are plotted individually to show the difference between individual trips, the evolution of travel times over the day, and the degree of dispersion in travel time values (i.e. the predictability, or not, of travel time for any journey).
  • One pair of charts shows average times, by hour, for each day to illustrate daily fluctuations and any before/after changes concurrent with the King Street Pilot.

For both routes, there is almost no change in the average travel times after the pilot began. Values on Queen bounce around a lot, but they do so both before and after the pilot began.

There is a quite striking weekly pattern with much higher than usual averages during the PM peak eastbound on Queen and southbound on Bay with low values usually on Mondays, and much higher values later in the week. This shows the importance of studying route behaviour over several days, while remaining aware that external events can create patterns in the data, or can create one-time disruptions for special events such as parades or sporting events.
