In the first two parts of this series, I reviewed headway and travel time data for the 29/929 Dufferin bus during April 2025.

• Service Analysis of 29/929 Dufferin Part I: Headways in April 2025
• Service Analysis of 29/929 Dufferin Part II: Travel Times in April 2025

This article reviews archival data back to January 2024 to discover how the route’s behaviour has changed in the past 16 months. At the end, there are charts showing travel times over the full route from April 2018 to April 2025 for a long view of their evolution.

The first part of the article looks at headways (the time between vehicles) on both the 29 local and 929 express services at various points along the route. The patterns visible in the earlier articles with ragged headways leaving terminals appear throughout data back to January 2024. A major problem with these routes is that buses do not leave terminals evenly spaced, and this problem grows as they move along the line.

The second part reviews travel times over segments of the route to show areas where these change by time of day, and where they do not. These show that on some segments, travel times are mostly consistent across time periods, whereas others show rises and falls. The segment with particularly wide variations is northbound from Lawrence to Wilson showing the effect of traffic queuing for Yorkdale Mall and for Highway 401.

The original RapidTO proposal for red lanes included the full route, but the current version is only from Eglinton southbound. This will not address congestion issues north of Eglinton, nor will it deal with the operational problem of erratic terminal departures.
