Construction Season 2009 (Updated)

This morning, I took a ramble around the city to have a look at various projects affecting the streetcar system.  For those who don’t see all of the sights, here’s a roundup.

Updated 5:20 pm:  A link to a more recent design layout for St. Clair Phase 4 (west from Caledonia) has been added.

Updated 6:20 pm:  John F. Bromley provided a route history for the Roncesvalles Shuttle which I have added to this article.

St. Clair

The now-and-forever St. Clair project is beginning to look as if it might complete in our lifetime.  Eastward from Dufferin, new track is under construction, and the excavation is completed all the way to Oakwood.  Once this section is connected at both ends, there will be continuous track once more from Yonge to just west of Caledonia.  It’s a start.

Meanwhile, road and sidewalk construction is underway on the south side of St. Clair east of Winona, and Oakwood is less of a disaster area albeit not yet completely opened.  West of Caledonia, utility and sidewalk work progressed west from the Newmarket Subdivision bridge, and is further along on the north than the south side.

Some comments on other threads here suggest that the design will change the underpass between Old Weston Road and Keele.  Any proposal to widen the road here would certainly not be a quick project.  The plans shown in the EA involve no widening (see detailed layout part 1, page 2), nor is any shown in the February 2009 version (see pages 5 through 7).  If someone has other, definitive information, please let me know.

Dundas

Work has just begun on watermain construction west of Bathurst Street.  This is supposed to end for September, but I will be astounded, given recent experiences with construction delays, if this happens.

All Carlton cars run to Dundas West Station, while the Dundas car goes to Bathurst Station, and a Dundas bus runs from Keele Station to Wolseley Loop.  Dundas streetcar service eastbound from Bathurst depends on how many cars actually reach Bathurst Station because short turns would miss the connection completely.

Roncesvalles

Overhead has been removed on Roncesvalles from Dundas to north of the carhouse except at the Howard Park crossing which now only has the east-west tangent wire for the eventual return of the Carlton car.

The streetcar track will be removed over the next two months to simplify watermain work, and will be replaced in 2010 on its new alignment as the street itself is rebuilt to the new design.  Considering that there has been streetcar service on Roncesvalles since 1908 (first a shuttle, then the Queen car, finally the King car), the absence of track and overhead will be a strange sight indeed.

Proposed changes at Queen and Roncesvalles are on hold, I believe, pending resolution of design issues including the eventual route of the Waterfront West LRT in this area.

Queen

Due to watermain and track construction, service on the Queen and Downtowner cars began diverting today as previously reported.  (For those who carp, with justification, about TTC signs, the diversion notice calls the route “Downtown” with a map showing the eastbound diversion running on Lombard, not Adelaide.)  This is expected to be in place for eight weeks.

Meanwhile, utility work west of Gladstone has reduced Queen to a single lane westbound through the underpass, and west from Noble (one west of Dufferin), construction occupies both curb lanes.

It will be interesting to see whether cars still take extended layovers at the ends of their trips, or simply short turn a lot.

Meanwhile, although the work is not visible from Queen, riders on the rail line above can see the considerable progress on the excavation of the new Dufferin Street approach from the north that will eliminate the jog at Queen for all traffic.  Just getting rid of the left turn queues in both directions should improve the streetcar and bus operations here.

Analysis of Route 29 Dufferin — Part III: Link Times

In the previous post of this series, I looked at headways along the Dufferin route for December 2006.  Now, I will turn to the Link Times, the length of time taken to get from one point on the route to another.

If these times are well behaved, this indicates that the requirement for a bus to cover this particular section is predictable even though it may vary over the course of a day or by day of the week.  Random interruptions occur rarely and the schedule can reliably make assumptions about travel times.

If Link Times are spread out over a wide range of values, particularly for trips at similar times of the day, then something in this area is making travel unpredictable, likely some form of congestion. 

When we are considering the reliability of a service and how it might be improved, areas and times with widely varying link times are a good place to start looking.   Conversely, if link times for a route are generally well-behaved, then variations in headways have some other cause than random interference from traffic.

Analysis of Route 29 Dufferin — Part II: Headways

In the previous post, I began my analysis of the 29 Dufferin route with a look at service on Christmas Day 2006.  Before turning to other specific days and their events, let’s look at the month overall as seen by the reliability of headways and link times at and between various points on the route.  This post presents the headway data, and in the next installment, you will see the link times.

The picture revealed by these data is not a happy one, although it will not surprise any regular user of the route.  Headways are a mess, especially in the evening.  The oft-cited “flexibility” of buses does not appear to yield service any more reliable than on the King car, and in some cases, the service is worse.  The fundamental problem is that very frequent services are left more or less to their own devices, and less frequent periods on such routes suffer from the effects of laissez-faire management.

Of particular note is the service on Sunday evenings, a period when classic TTC excuses about “traffic congestion” simply are not credible.  Headways are scattered over a range up to 20 minutes even though the schedule says 10.

Analysis of Route 29 Dufferin — Part I: Introduction

Early in 2007 when I started looking at the TTC’s vehicle monitoring (CIS) data, I thought to be finished with it long ago, to have blazed through many routes and written wonderful commentaries on all of them.  Things didn’t quite work out as I had planned, and I got bogged down with competing issues and other calls on my time.  Also, the programs that digest, massage, and otherwise render presentable the TTC’s data needed some housecleaning both to make them more robust and to reduce a lot of the manual work that went into the early analyses on 504 King.

Things are much simpler now, although the challenges of interpreting the data remain with each route offering its own peculiarities.  Now I turn to the Dufferin Bus, a frequent route for which the TTC receives many complaints about service.  How will it compare to routes we have seen already?

The route is 13.56km from Dufferin Loop to Wilson Station, although half of the scheduled peak service runs only to Tycos Drive about 3/4 of the way to the north end of the line.  This is in the same range as the Carlton and King cars, although they spend much more time in “downtown” conditions.  It is shorter than the 16.65km Queen-Humber route, and of course much shorter than the 24.43km Queen-Long Branch route.

The scheduled service is generally more frequent than on the streetcar lines, although with smaller vehicles so that headways are better for any level of demand scaled to capacity.

As I have done on previous routes, I will look first at the data for Christmas Day 2006 as this shows the route in its simplest state without any effects from traffic congestion, weather or heavy passenger loads. Continue reading →
