This article is a companion to Part 1 of my update of travel time behaviour on key routes for 2020-2022. That article dealt with routes east of Yonge Street, and this part turns to routes west of Yonge:

• 29 Dufferin from King to Wilson
• 35 Jane from Eglinton to Steeles
• 60 Steeles West from Finch Station to Kipling

These three routes show more variation over time than most of the routes east of Yonge reviewed in the first article. The greater variation implies that they are more sensitive to changes in overall road demand and have less headroom to begin with. They are more likely to benefit from priority measures, but taking road space for transit will be more politically challenging in car-oriented areas.

Any detailed study that purports to establish time savings through red lanes must be careful to be an apples-to-apples comparison avoiding projected savings against conditions (construction projects and future route changes) that will change on their own. Similarly, and by reference to what was done on the Eglinton-Kingston corridor, “savings” due to stop eliminations, if any, should not be counted as a “benefit” of transit priorty.
