A minor 2-lane roadway with design speed of 45 mph crosses a major 2-lane roadway with design speed of 50 mph at 90 degree angle at an at-grade T-intersection. All lanes are 12 ft wide. If a stop sign is installed on the minor road, determine the dimensions ofallrequired clear sight triangles at this intersection for passenger cars(Case B, stop sign control on the minor road).
A large grain elevator is located 40 feet from the centerline of a two-lane highway (55 mph speed
limit, 12-ft lanes and level terrain). The elevator is situated on the inside of a horizontal curve
with a radius of 500 feet measured to the centerline of the highway. Assuming that the elevator
is the only sight restriction on the curve, what is the available sight distance along the curve
(measured to the center of the inside lane)? Does adequate stopping sight distance exist?
A two-lane minor road intersects a four-lane undivided major road at 90 degrees,forming a four-leg intersection with traffic on the minor road controlled by a stop sign. The designspeed on the major road is 80 km/h. The approach grade on the minor road is 5%. A single unit truckon the minor road would like to make a left turn onto the major road. Using the AASHTO procedure,determine the minimum sight distance required on the major road for the truck to make a left turnonto the major road.

- 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.arrow_forwardFor the STOP-controlled intersection show below, is the sight distance sufficient for safe operations?
