A rural collector highway is to be constructed in an area of rolling terrain where the ADT is 950 veh/day. For this situation, determine the following design values:
a. Minimum design speed
b. Desirable lane width and shoulder width
c. Maximum desirable grade
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
