Qu.
A two-lane minor road with a +5% approach grade intersects with a four-lane
undivided road. Determine the minimum intersection sight distance on the major
road required for a stopped single-unit truck to depart from the minor road (in the
upgrade direction) and turn right onto the major road. The design speed is 30 km/h
on the minor road and 50 km/h on the major road.
A two-lane minor road intersects a two-lane major road at 90° forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 125 ft from the centerline of the outside lane of the major road and 35 ft from the centerline of the nearest lane of the minor road. Determine the maximum speed that can be allowed on the minor road if the speed limit on the major road is 45 mi/h.
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.
