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.

From Yonge to Spadina westbound, we can see a variety of effects.  In week 1, there are short-lived congestion effects or delays on three days.  Week 2 is much quieter, similar to the situation we saw in the Neville to Yonge data.  In week 3, there is a major delay around 0900 on Wednesday, Dec 20, and a wave of congestion peaking around 1500 on Friday, Dec 22.  Week 4 (Dec 27-29) is very quiet.

The Saturday pattern is completely different.  Running times build up through the morning and stay at a consistent level until late evening.  However, the evening data is more scattered showing the effect of congestion in the entertainment district.  This mirrors the data for King Street westbound which I have not yet published.

Sundays are a bit quieter, but you can see the big change on the evening of Dec 31 that behaves much more like a Saturday.

The data for eastbound trips in this link behave somewhat differently reflecting the fact that, from a congestion point of view, we are facing “into the funnel” rather than “out of it”.  Link times are longer and the afternoon buildup lasts well into the evening.  The New Year’s Eve times rise starting about 2100 and the trend line goes right off the chart by midnight.

From Spadina to Strachan westbound (this link brackets Bathurst Street and contains the emerging “new” Queen West strip), there is much less variation in link times, although the Dec. 22 early rush/shopping peak is quite evident.  This segment also shows some congestion effects on the Saturdays before Christmas.  Eastbound, the effects are less severe, although Saturday afternoon congestion is actually worse than on weekdays, and there is a clear build-up on New Year’s Eve.

The link from Strachan to Gladstone is quite flat with little scatter in the data.  This reflects this area’s lower economic level and the amount of property that generates little traffic.  This will change quite dramatically over the next few years as redevelopment adds several thousand new condo dwellers.

From Gladstone to Wilson Park (just east of Roncesvalles), we come into an area that is economically stronger, and where traffic jams are common due to traffic passing through the area.  The Landsdowne-Jameson intersection is always the source of congestion as it is part of a route to the Gardiner Expressway, and this link as a whole is usually delayed when events on that expressway cause traffic to spill onto local streets.

The spillover effect is visible on Friday December 1 (we also saw this effect on King, but at a much worse level).  In week 2, interestingly, the peak in running times comes in the afternoon.  Since we know already that week 2 was basically quiet, this indicates that something was systematically causing congestion in this area for one week, possibly a construction project.  In week 3, we see the mid-afternoon peak on December 22, but other days are uneventful.  Week 4, similarly, has quite flat data.

Saturdays show a different story, particularly before Christmas and especially on December 2 where the congestion lasts well into the evening.  Sundays show a slight increase in link times during the afternoon, but nothing extraordinary.

Eastbound data for this link do not show as much variation as the westbound data, although the same congestion appears on December 2.

From Wilson Park to Parkside bothways, we will see mainly the delays, if any, at the Queen-Roncesvalles intersection.  This section is fairly well-behaved, and there is not a large number of trips with long delays as we had near Russell Carhouse in Part V.  Periods when running times are extended correspond to congestion problems we have already seen further east on the line.

The Parkside to Queensway-Humber link takes us to the entrance of Humber Loop.  Data in this area is a bid dodgy, and I have chosen the link’s boundaries to eliminate the worst of measurement effects right at the loop, as well as any layovers.  For some reason, this didn’t work for every trip, especially on Christmas Day when cars had a very large amount of extra running time and took very long layovers.  This shows up as outliers for that day only in this link westbound. 

The eastbound data are also affected by resolution problems at Humber and cannot be relied upon.  As in other situations where CIS data are unreliable, the quality of analysis will greatly improve when CIS is converted to GPS-based measurements.

In the final part of this series on link times, I will turn to the service on Lake Shore to Long Branch.
