Understanding Sight Triangles in a Complete Streets World

Thank you

The live event has ended. Recording now available to stream. 

This webinar was sponsored by the ITE Traffic Engineering Council.

Webinar Description:

Sight triangles are considered a basic cornerstone of safety for driveways and intersections. Yet despite the wide recognition of role of sight triangles on safety, the understanding and implementation of sight triangles varies substantially. Numerous variables such as assumed traffic speed, vehicle stopping position, and eye height can have a substantial impact on sight triangles for vehicles. Rarely addressed in many instances are stopping sight distances for bicycles, which have different braking capabilities and eye heights versus passenger cars, or other higher speed micro-mobility devices such as electric scooters and segways. Sight triangles can also be important for pedestrians, particularly for right-in/right-out driveways. This webinar will delve into these issues, as well as strategies to address improving sight triangles or providing appropriate warning signage.

Learning Objectives:

  • Show how to measure sight triangles.
  • Explain sight triangle considerations for complete streets
  • Identify how to improve sight triangles or when to provide warning devices
