Webstopping sight distance. A formal design exception is required for a vertical curve that does not provide at least the acceptable stopping sight distance highlighted in yellow in the criteria tables from Section 1C-1. • Refer to Section 6D-1 for criteria on measuring sight distance on vertical curves. WebFor stopping sight distance, the average height can be assumed as 0.7 m since the height criteria are 1.2 m for the eye and 0.15 m for the object. Cut slopes should be kept clear above this height at the midpoint of the sight line by cutting back the slope or benching.

Note that design intersection sight distance criteria for stop-controlled intersections are longer than stopping sight distance to ensure the intersection operates smoothly. 3.3.2. Skewed Geometry WebStopping Sight Distance Stopping sight distance (SSD) is the length of roadway ahead that is visible to the driver. This distance allows a driver to see an object in the roadway and stop their vehicle before colliding with the object. A roadway should be designed to provide continuous stopping sight distance throughout the route. ip65 fluorescent light fittings
