A developer has requested permission to build a large retail store at a location adjacent to the intersection of an undivided fo
ur-lane major road and a two-lane minor road. Traffic on the minor road is controlled by a stop sign. The speed limits are 40 and 55 mi/h on the minor and major roads, respectively. The building is to be located at a distance of 70 ft from the near lane of one of the approaches of the minor road.
Determine where the building should be located relative to the centerline of the outside lane of the major road in order to provide adequate sight distance for a driver on the minor road to turn right onto the major road after stopping at the stop line. Design vehicle is a single-unit truck. Lanes on the major road are 12ft wide. Median width in the major road is 8ft and the approach grade on the minor road is 4%.
