![]() Subsequently, factors to adjust intersection sight distances for skewness are suggested for use only when angles are less than 60 degrees (AASHTO, 2011). The Green Book states that although a right-angle crossing normally is desired, an angle of 60 degrees provides most of the benefits that are obtained with a right-angle intersection. However, there is some inconsistency among reference sources concerning the degree of skew that can be safely designed into an intersection. In addition, the amount of time required to maneuver through the intersection increases, for both vehicles and pedestrians, due to the increased pavement area. Decreasing the angle of the intersection makes detection of and judgments about potential conflicting vehicles on crossing roadways much more difficult. There is broad agreement that right-angle intersections are the preferred design. Accessible Pedestrian Signal (APS) Treatments. ![]()
