Updated February 11, 2023 at 1:45 pm: In response to a reader comment, I have added illustrations from the City’s presentation deck showing the technologies used for traffic monitoring and analysis at the end of this article.

This article continues a series of reviews of operations on the King Street Transit Priority Lane of which the most recent is King Street Travel Times: May-December 2023.

On February 9, 2024, Mayor Chow held a press conference to announce various changes coming to King Street and the success of the Traffic Agent program in taming congestion downtown, particularly on King.

Regular readers will know the graphs below showing day by day travel times eastbound from Bathurst to Jarvis by hour from 3pm to 9pm. These charts have been updated with January 2024 data. (Note: Gaps in the charts in mid October and early December correspond to diversions via Church and Queen for water main repairs east of Jarvis. No streetcars covered the full Bathurst-Jarvis segment during these periods.)

The graphs illustrate the change in congestion levels peaking in the 5-6pm hour, but still quite evident in 6-7pm and to a small extent in 7-8pm. The build-up through the fall was caused by construction on Adelaide coupled with a complete lack of enforcement of the transit corridor and of “box blocking” at major intersections where cars enter but cannot cross in the allotted green time. With the introduction of Traffic Agents to enforce the rules on November 27, 2023, the street ran much more smoothly and the peak in congestion vanished.
