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.
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 speed limits are 35 and 50 mph, respectively. The building is to be located at a distance of 65 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 both roadways are 12 ft wide. Grades are approximately level.
3. A developer has applied for a construction permit for a building at the southeast corner of an
intersection. The intersection is controlled with a stop sign on the minor road. The four-lane
major road in the east-west direction has a design speed of 50 mph. The two-lane minor road
is controlled by a stop sign. Determine whether the permit should be approved for the
following conditions.
a. Design vehicle - Single-Unit truck
b. Approach grade = 4%
C. Maximum feasible distance of the building from the center of the nearest lane of the
four-lane road = 21 ft
d. Maximum feasible distance of the building from the center of the nearest lane of the
two-lane road = 15 ft

- A two-lane minor road intersects a two-lane undivided major road at 90 degrees, forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 50 m from the center line of the outside lane of the major road and 14 m from the center line of the nearest lane of the minor road. A passenger car on the minor road would like to cross the major road. Using the AASHTO procedure, determine the maximum speed that can be allowed on the minor road if the design speed on the major road is 80 km/h. Assume a 3% approach grade for the minor road.
