Analysis of 501 Queen: Part VII — Humber to Long Branch

This is the final section of a three-part post about link times on the Queen Car.  Previous sections dealt with Neville to Yonge, and Yonge to Humber.  A detailed description of the concepts used in these analyses is in the first post.

Long Branch has been particularly hard hit by TTC service decisions over the years.  Originally a separate route, the 507 Long Branch car ran between Humber and Long Branch providing a 10-minute off-peak service and a 7-minute peak service supplemented by a few trippers than ran downtown to Queen & Church in the AM peak with outbound trippers in the PM.

This changed when the TTC amalgamated the 501 Queen service with the 507, and further with the replacement of CLRVs (50-foot cars) by ALRVs (75-foot cars).  The scheduled headway on Lake Shore is now:

  • 9’45” AM Peak
  • 11’00” Midday and PM Peak
  • 14’45” Early evening M-F
  • 20’00” Late evening M-F
  • Saturday service ranges from 11’30” in the afternoon up to 18’00” in the late evening
  • Sunday service ranges from 14’30’ in the afternoon up to 23’00” in the late evening

The posted schedules on the TTC’s website are a complete mess with irregular headways shown throughout the day.  This is clearly a problem with their schedule-production software which has been known to produce other gaffes in the generated timetables.  The fact that such timetables are created for public consumption with such glaring errors tells us a lot about quality control at the TTC.

It is bad enough that riders on Lake Shore must endure much wider scheduled headways than on many other parts of the system, but as we will see, the actual service provided is much, much worse.  When scheduled service is infrequent, provision of on time service, and all of the service, is essential.

Analysis of 501 Queen: Part VI — Yonge to Humber

This post continues the series looking at link times between various points on the Queen route.  The ideas behind this are discussed in more detail in Part V.  In brief, if we look at the time taken by every trip between two points, and we collect data from several similar days together (weekdays, weekends), we should see patterns that recur every day and can be planned for, as opposed to individual, unpredictable events.

The first post in this series dealt with the section from Neville to Yonge, and the next one will look at the section from Humber to Long Branch. Continue reading

Analysis of 501 Queen: Part V — Neville to Yonge (Updated)

[My apologies in advance if you are getting tired of reading about the Queen car. In anticipation of the public meeting on this subject on Tuesday, December 4, I am trying to push a lot of material out the door.

[Updated at 7:45 pm December 2:  Full-month charts for headways at Woodbine bothways have been added to show the range of values over the entire month.]

This post concerns link times, something I didn’t go into in the previous series on the King Car (I will be adding a post on King link times soon).

First, a bit of background to explain why anyone should care about these charts.

If we break a route up into segments, we can look at the time taken by each vehicle to tavel from “A” to “B”, the beginning and end of the segment. If these times stay fairly steady over an entire day, then it follows that conditions at all times match those at the best of times. In other words there is no improvement to be achieved by relieving “congestion” or any other source of delay unless we can prove that it’s there all day, every day.

A related issue is the degree of scatter in the values. Even if the average stays constant, we could have widely varying individual times for each car. This would indicate something was happening to randomly delay cars over this segment of the line.

In many areas, we will see increases and decreases in the average time, as well as changes in the scatter of times showing conditions as they evolve over the day. Put multiple days’ data together on one chart, and we can see whether there are events on specific days that are out of the ordinary behaviour of the line. Such events cannot reasonably be planned for, although it would be helpful to have a routine strategy to deal with the common types of events (e.g. major events in The Beach, at City Hall, at the CHUM/City building).

This series of posts will look at the line from end to end to review the way each segment actually operated in December 2006. Continue reading

Transit Service in Ottawa

For those who have been following my analyses of problems with TTC streetcar operations, David Cavlovic has sent along an article from today’s Ottawa Citizen

Toronto may have its problems, but Ottawa sounds even worse, including a lacklustre attitude by senior management.  At least here, there is a glimmer of recognition that service could be better.

One comment from the article struck a chord with me:

The company has spent a lot of money on a GPS system, but it lacks the software to analyse where service problems actually lie.

TTC’s signpost-based CIS has been in place for over two decades, but analysis of its data waited until I undertook it and started publishing results here.  CIS will be updated to use GPS information from vehicles where this is now available thanks to the stop announcement system, but we have yet to see whether the TTC will actually analyze its operations with all of the data at its disposal.

Analysis of 501 Queen: Part IV — Saturday & Sunday December 9 & 10, 2006

Weekend operations on Queen have some problems in common with the weekday service, but these show up at different times and locations.  In place of rush hour effects, the line is affected by shopping and entertainment-related congestion that builds and ebbs over longer periods.

On Saturday, the service is reasonably well behaved until early afternoon, but at that point, bunching sets in.  As on weekdays, there appears to be no effort to space out the service and pairs of cars travel across the city together.  This is difficult to justify especially considering the long layovers most cars get at Humber and Long Branch.

Will The TTC Ever Finish On St. Clair?

I spoke to Vice-Chair Joe Mihevc at the TTC meeting on Wednesday about the situation at St. Clair West and on the portion of the line east to Yonge.  Here is the current status.

The problem with rebuilding the track is that there is one section on the east side of the loop where there are electrical cables buried in the concrete.  Breaking up the concrete so that these can be moved is a delicate business and won’t be done for a few months.  Meanwhile, the rest of the loop is being installed.

In about two weeks, this will allow pavement restoration in most of the loop.  At that point, the buses that enter from the west will be able to loop down the ramp and around the west and north sides of the platform.  They will all exit via the ramp that comes out in the Loblaw’s building on the north side of the street.

Meanwhile, Mihevc is getting a complete runaround from staff on the installation of new shelters.  It’s always something that will happen in a week or two, and has been like this since the summer.  He is getting very frustrated because he takes the blame every time he parrots information to his constituents.

TTC staff should carefully consider what they are doing.  Mihevc has defended staff positions on the St. Clair right-of-way against all criticisms and burned up some of his credibility, with me among others, in the process.  The last thing the staff needs is to lose that champion in the Vice-Chair’s office.  If he stops believing what he is told, they are in big trouble.

Of course, many of us stopped believing what staff said about St. Clair a long time ago.  Vice-Chair Mihevc has some catching up to do.

Analysis of 501 Queen: Part III — Monday, December 4, 2006

December 4 was an odd day.  The weather was uneventful, and service on the nearby King route was well-behaved (see the analysis of 504 King).  CIS Control seemed to adopt an unusual strategy to “managing” the Queen service to the point that short turning must be described as “aggressive” if not “pre-emptive”.

  • Most of the “Humber” service actually short-turned at Roncesvalles.
  • Many of the cars on both branches short-turned at Woodbine Loop.
  • There is little evidence of serious traffic congestion or major delays in the charts, but ragged headways and bunched cars were common.

Analysis of 501 Queen: Part II – Friday, December 1, 2006

December 1, 2006, was not a good day for transit operations.  As I have already discussed for the King route, it was probably the worst day of the month.  The weather was bad through the afternoon and early evening, and severe congestion problems affected many routes.

This is a contrast to Christmas Day, discussed in the previous post, where good weather coupled with little congestion or passenger surges made for ideal conditions.

Among the problems we will see for December 1 are:

  • bunching of cars due to congestion
  • pairs of cars running together over the entire route
  • large gaps to the termini
  • congestion, most severely in an area well away from downtown, and only in one direction

This shows what the line looks like under worst case conditions.  Even though the service is seriously disrupted, this data has important lessons about how the line is scheduled, managed and operated. Continue reading

“Driver Bob” Writes About the Queen Car (Updated, Again)

I received a long comment in reply to an earlier post about service in the Beach from a TTC operator, and this deserves its own thread.

Updated November 11:  Driver Bob left a short note attached to the wrong thread in which he dismisses the discussion here.  I have added it to the end of this post just before the comments. 

A second comment, apologizing for the first, has also been added.

Analysis of 501 Queen: Part I – Introduction & Christmas Day 2006

The Queen streetcar is the subject of much discussion here, and I have been remiss in failing to post an analysis of the CIS (Communications & Information System) data for this route to substantiate many of my (and everyone else’s) observations.  Over the next few weeks, in preparation for a Rocket Riders’ meeting in early December, I will post a series of articles looking at the line’s operation in detail.

For those who are unfamiliar with the sort of analyses that will appear here, please read all of the articles about the King route filed under Service Analysis on this site.  As I write this, there are nine of them (with one more to come), and you should read them in order.  They include some of the background on how the CIS system works and the various ways I have sliced and diced that data.  I will not repeat this information here in the interest of brevity.

By way of introduction to the data, this post deals with Christmas Day, 2006.  This is important for a few basic reasons:

  • Operating conditions on Christmas were as close to ideal as one could ask for.
  • There was no traffic congestion.
  • There was no inclement weather.
  • Passenger loads were modest.

Collectively, this means that the observed behaviour of the line shows what happens when most of the sources of random delay are eliminated. Continue reading
