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).
A two-lane minor road intersects with a four-lane major street at 90 deg, forming a 4-leg intersection with traffic on the minor road controlled by a stop sign. The speed limits were 45 mph on the major road, and 25 mph on the minor road. Determine the intersection sight distance (ISD) when a passenger car wants to make a left turn onto the major street. (The grades of both road are low than 3%)
Q3: A four-leg intersection with no traffic control is formed by two-lane roads with the speed limits on the minor and major roads being 15 and 25 mi/h, respectively. If the roads cross at 90° and a building is to be located at a distance of 45 ft from the centerline of the outside lane of the major road, determine the minimum distance at which the building should be located from the centerline of the nearest lane on the minor road so that adequate sight distances are provided.
