A two-lane minor road intersects a two-lane major road at 90° forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 125 ft from the centerline of the outside lane of the major road and 35 ft from the centerline of the nearest lane of the minor road. a) Determine the maximum speed that can be allowed on the minor road if the speed limit on the major road is 45 mi/h. b) If the speed limit on the major road were 40 mi/h, determine the minimum distance that the building can be located from the centerline of the outside lane of the major street.
A minor 2-lane roadway with design speed of 45 mph crosses a major 2-lane roadway with design speed of 50 mph at 90 degree angle at an at-grade T-intersection. All lanes are 12 ft wide. If a stop sign is installed on the minor road, determine the dimensions ofallrequired clear sight triangles at this intersection for passenger cars(Case B, stop sign control on the minor road).
