EXHIBIT A
(To Be Used At Controlled Intersections)
The corner cutoff for sight distance visibility at controlled intersections is defined as that triangular area between the street right-of-way lines and a diagonal line formed based on a straight line between the following two points: Point A shall be located at a point which measures 7 feet behind the "stop bar" along the centerline of the street. Point B shall be established based on the critical speed, or posted speed, of approaching vehicles in feet per second (miles per hour x 1.5) times 4 seconds.
EXHIBIT B
(To Be Used At Uncontrolled Intersections)
The corner cutoff for sight distance visibility at uncontrolled intersections is defined as that area between the street right-of-way lines and the diagonal lines formed based on a straight line between the following points: Point A shall be located at a point which measures 17 feet behind a prolongation through the intersection of the curbline or edge of pavement along the centerline of the street. Point B shall be established based on the critical speed, or posted speed, of approaching vehicles in feet per second (miles per hour x 1.5) times 4 seconds.
Point A and Point B shall be established on each leg of the intersection. A diagonal line between Points A and B will create overlapping triangles formed by the street right-of-way line and the diagonal line.
