A developer has requested permission to build a large retail store at a location adjacent to the intersection of an undivided four-lane major road and a two-lane minor road. Traffic on the minor road is controlled by a stop sign. The design speeds are 60 and 80 km/h on the minor and major roads, respectively. The building is to be at a distance of 20 m from the centerline of 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 medium single-unit truck on the minor road to proceed safely across the intersection after stopping at the stop line. Assume a 3.6-m lane width and a 3-m distance from the stop line to the near edge of the major road.
