This would encourage designers to consider pedestrian needs when designing intersections. Capacity Considerations . Guidelines based on the number of pedestrians using an intersection and the physical characteristics of pedestrians could provide criteria for designing walkways, queuing areas, street corners, and crosswalks. Alignment and Profile . While the Green Book emphasizes that intersections are points of conflict for vehicles and pedestrians, it does not provide guidelines for reducing conflict.
Hills surrounding intersections can also block sight lines for vehicles and pedestrians.
Intersection Curves and Turning Radii . Where the radius of a curve accommodates vehicles of all lengths, there is a buffer zone needed to provide safety for pedestrians. The authors suggested further guidelines for curved suburban and rural intersections. In addition, the angle of crosswalks at curves requires further clarification. Research suggests crosswalks at right angles to the curve would be safest.
