Updated February 7, 2025 at 8:00pm: It occurred to me that although charts here are produced with maximum Y-values of an hour, or even 90 minutes, that this shows the peak times while compressing the visual range of the area where averages change over time. I have added a second set of charts for 2016-2025 with the maximum Y of 30 minutes to give the area where averages move between 15 and 25 minutes more “elbow room” and to make the evolution of values easier for readers to see. These have been added at the end of the “Implementing the Transit Mall” section.

In previous articles, I have posted charts showing the changes in travel times on the central portion of the 504 King route between Jarvis to Bathurst. This is the area covered by the supposed transit mall, although the degree to which streetcars actually have priority has varied over time for various reasons.

This article will review how travel times have evolved in recent years, as well as looking back to pre-pandemic and pre-transit mall eras. Full chart sets are available via links to PDFs for those who are interested.

Beyond that central section lies the conventional “streetcar” portion of the route west through Bathurst/Niagara, Liberty Village and Parkdale. To the east is the northern reaches of the St. Lawrence and Distillery districts. Do these deserve the same level of priority treatment? What would be the benefit if any? I will turn to those areas later in the article.

For those familiar with similar analyses on this site, I have retained the format of charting the 50th percentile (median) and 85th percentile values. These show both the general trend over time as well as the degree by which trips can vary from the median affecting reliability both in the priority area and on the broader route.

Significant events include the implementation of transit priority in November 2016, the covid lockdown in March 2020, and the effect of enforcement (or lack of it) on the ability of streetcars to move briskly through the priority area. Also important to note is that the effects differ by time and direction, and that congestion interferes with transit not just during the classic peak periods.

The important history lesson on King Street is that transit priority can improve travel times, but more importantly can improve reliability leading to more predictable trips and vehicle spacing over a route even beyond the bounds of the priority scheme’s area. Moreover, the benefits are easily lost through lack of enforcement and external events that significantly change demand on the road network.
