Specified areas along intersection approach legs and across their included corners should be clear of obstructions that might block a driver's view of potentially conflicting vehicles These specified areas are known as clear sight triangles The dimensions of the legs of the sight triangles depend on the design speeds of the intersecting roadways

What is the clear sight triangle?

The area needed for provision of this unobstructed view is called the Clear Sight Triangle (see Figure 3). Figure 3. Sight Distance Triangles for 4-Leg Stop-controlled Intersections 9 The Intersection Sight Distance (ISD) is measured along the major road beginning at a point that coincides with the location of the minor road vehicle.

What should the sight distance be at an intersection?

As a general consideration, the sight distance should be equal to or greater than the minimum values for specific intersection conditions. Specified areas along intersection approach legs and across their included corners should be clear of obstructions that might block a driver's view of potentially conflicting vehicles.

What should the alignment of the intersection be?

The alignment should be as straight and the gradients as flat as practical. The sight distance should be equal to or greater than the minimum values for specific intersection conditions.

Why are geometric intersections dangerous?

The geometric design of intersections can create navigational problems for motorists, potentially contributing to crashes at these locations. Among geometric design elements, two specific issues can cause safety concerns: sight distance limitations and skewed geometry. 3.3.1. Sight Distance
