A horizontal curve is being designed to connect two tangents that intersect on a rural collector road with a specified design volume of 2500 veh/day (i.c. design speed 60 mph). It is expected that, because of right-of-way restriction, a large billboard will be placed at a distance of 50 ft from the centerline of the inside lane. If the terrain can be described as level and only a minimal amount of snow is expected on the road, determine the minimum radius of curve. Assume maximum superelevation rate (e) of 0.1 and fs-0.12. Ans: 1090 ft

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.

Question

A horizontal curve is being designed to connect two tangents that
intersect on a rural collector road with a specified design volume of 2500 veh/day (i.c. design
speed 60 mph). It is expected that, because of right-of-way restriction, a large billboard will be
placed at a distance of 50 ft from the centerline of the inside lane. If the terrain can be described
as level and only a minimal amount of snow is expected on the road, determine the minimum
radius of curve. Assume maximum superelevation rate (e) of 0.1 and fs=0.12. Ans: 1090 ft

Question The design speed of a highway is 80 km/hr and the radius of the circular curve is 150 m in plain topography. Which one of the following is the minimum length of the transition curve?
A curve of radius 250 ft and e 0.08 is located at a section of an existing rural highway, which restricts the safe speed at this section of the highway to 50% of the design speed. This drastic reduction of safe speed resulted in a high crash rate at this section. To reduce the crash rate, a new alignment is to be designed with a horizontal curve. Determine the minimum radius of this curve if the safe speed should be increased to the design speed of the highway. Assume fs= 0.17 for the existing curve, and the new curve is to be designed with e = 0.08
A two-lane highway is being expanded to four lanes with the original highway consisting of the northbound lanes and the new highway carrying the southbound lanes. At one location, the southbound facility crosses over an existing pipeline. The resulting vertical curve needs to be at least 10 feet above the top of the pipeline. The initial grade is -4 and G2 is +2. The design speed for the new highway is 60 mi/hr. (1) Is the length of the design curve greater or less than the required stopping distance? (2) The PVI is at station 425+74 and the elevation is 980 ft. If the pipeline is at station 424+54 and the elevation of the top of the pipeline is 985 ft, is the distance from the curve to the top of pipeline adequate to meet the 10 feet required cover? I recommend drawing the cross-section of the curve including the location of the pipeline when answering this question. Note that instead of clearance from the curve up to the the bottom of the overpass (example in the book), this is…
