Why implement these intersection changes at Pinetree Way and Guildford Way?

According to ICBC data, 82% of crashes in the Lower Mainland with pedestrians happen at intersections. Implementing these intersection changes (i.e. protected left turns, no-right-turn-on red etc.) significantly reduces the likelihood of serious crashes, in particular at a high-volume intersection like Guildford Way and Pinetree Way. From 2018 to 2022, there were 142 crashes at Guildford Way and Pinetree Way reported to ICBC. 

No right-turn-on-red: 

  • Eliminates the challenge for drivers to pay attention to both oncoming vehicle traffic from the left and people crossing the street; and
  • Prevents drivers from pulling out into the crosswalk while people are still crossing the street. 

Protected left-turn phasing:

  • Eliminates nearly all conflicts between left-turning drivers, oncoming vehicle traffic, and people crossing the street
  • Reduces the challenge for drivers by eliminating the need to monitor both oncoming traffic and people crossing the street, simplifying driver decision-making (such as waiting for gaps in traffic)
  • Reduces left-turn crashes for all modes by as much as 99% when they replace permissive left turns.

Conversion of slip lane to standard turn lane:

  • Simplifies the intersection design, making it easier to navigate for people walking, rolling and biking;
  • Slows down drivers making right-turns ;
  • Improves the visibility of oncoming traffic, pedestrians and micromobility users for drivers; and
  • Creates space for the protected intersection design.

Leading interval for people walking and using micromobility devices: 

  • Improves the visibility of people walking and using micromobility devices to drivers making right turns.
