Updated July 18, 2020 at 2:00 pm: 29 Dufferin is a route that I have been tracking for much longer than most bus routes. To give a longer perspective into travel times on the Dufferin corridor, I have added a section looking back to 2011.
Route 29 Dufferin is one of five corridors proposed for rapid implementation of reserved bus lanes in a proposal that will be at the TTC Board on June 17. Others include Finch East, Eglinton-Kingston-Morningside, Steeles West and Jane.
In this article, I will review travel times and speed data for Dufferin comparing conditions in April 2018 and May 2020. (2018 is used because I do not have any more recent pre-covid data.) The premise of this comparison is that May 2020 represents conditions on the route with all or most traffic congestion removed revealing the underlying conditions that would apply in a best case transit priority lane implementation.
Dufferin Street is very different from the other proposed corridors because for much of its length it is only four lanes wide with houses and businesses fronting onto the street and little or no opportunity for widening. On the northern portion where the street allowance is wider, there is a combination of four through traffic lanes with bays for right turns and bus stops.
Creation of a reserved lane will involve both a reduction of capacity for non-transit traffic and removal of parking. Depending on whether the lanes are in effect only during peak periods or longer, parking will be a big political issue as it was for attempts to improve transit operations on streetcar routes.
Before the King Street Pilot was proposed, the City reviewed parking regulations on the shoulders of peak periods to determine whether they should be extended. (Full disclosure: I worked on this project as a consultant.) With the growth of traffic over many years, the peak had expanded beyond its traditional 7-9 AM, 4-6 PM periods. Travel time charts would clearly show two super-peaks on either side of the official two-hour period as transit vehicles were fighting peak level congestion when parking and turn restrictions were not in effect. From this study, many areas had their peak periods extended by 30 or 60 minutes on either side of the original hours so that the period could be as long as 7-10 AM and 3-7 PM.
There was a lot of push back on this scheme from local businesses who regarded parking as essential to their operations, and there were tradeoffs in the final scheme to limit the expansion of peak restrictions. For example, a proposed no parking restriction on Broadview near Danforth was changed to end at 6:30 pm instead of 7:00 pm. It is worth noting that on Queen Street in The Beach there are no extended restrictions and the traditional two-hour windows apply. It would be intriguing to know whether Councillor Bradford, the author of the motion, would agree to elimination of parking in his ward in the name of speeding up the Queen car.
Parking is already banned in some locations on Dufferin Street from 7-10 AM and 3-7 PM, but the traditional hours are more common, and some locations have no restrictions at all. There are many locations where motorists would routinely move into a “reserved” curb lane to access off-street parking and laneways, as well as for right turns.
There is also the question of how bicycles would fit into any new street design.
Overall, the challenges on Dufferin Street are not straightforward and, like the much shorter King Street Pilot, they will require detailed block-by-block review.
Travel Times Between King and Wilson
In the following charts, note that changes in travel times will be due to a combination of two factors: the level of traffic congestion and the time spent at stops loading and unloading passengers. Transit priority can reduce the effect of congestion, but stop service times are a function of service level and demand, and especially of the degree to which crowding prevents a speedy movement of passengers onto and off of buses.
Budgetary constraints drive the TTC to run as close to its capacity standards, if not over them, as a routine practice. The degree of crowding is only rarely reported, and the cost in terms of service delays is not considered. A vicious circle can develop where headways are widened and travel times stretched in response to this type of delay, but this reinforces crowding problems while providing a “no cost solution” so beloved by simplistic political analysis.
