The center-line of the inside lane of a roadway is on a horizontal curve with a 6o54'29" degree of curvature. The central angle of the curve is 40o. There are 6-foot-high snow banks 15 feet from the center-line of the inside lane. The inside lane has no grade and has a posted speed limit of 55 mph. Assume a vehicle is traveling at the posted speed and that the perception-reaction time for the driver is 1.5 seconds. Each question is worth 2 points. How long (time) does it take a vehicle to stop from the time the brakes are applied? Enter your answer accurate to 3 significant figures.

A large grain elevator is located 40 ft from the centerline of a two- lane highway, which has 12-ft lanes. The elevator is situated on the inside of a l12° horizontal curve. a) Assuming that the elevator is the only sight restriction on the curve, what is the minimum sight distance along the curve? b) What should be the maximum speed recommended for this curve? c) If the designer wants to have the design speed of 10 mph higher that the recommended speed, what is the distance required for the movement of the elevator?
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 islocated 185ft from the center line of the outside lane of the major road. The design speed on themajor road is 60 mi/h and the design speed on the minor is 35 mi/h. The approach grade on the minorroad is 3%. A passenger car on the minor road would like to cross the major road. Using theAASHTO procedure, determine the minimum distance required that the building must be from thenearest lane on the minor road

A one lane loop ramp at the northwest quadrant of an interchange, this loop ramp is for northbound vehicles to change travel directions towards the west. The friction factor between the tire and the pavement is 0.095. If the design speed is 35 mph and the radius of the loop ramp is 545 ft measured to the centerline What should be the super elevation ?
What is the appropriate super elevation rate for a curve with a 1,200-ft radius on highway with a design speed of 60 mi/h? The maximum design super elevation is 6% for this highway.
Design speed of a six-lane undivided highway is 70 mph. A circular section of the highway has level grade, 10-ft wide lane, and the radius of the highway centerline is 1000 ft.

2. The intersection is controlled with a stop sign on the minor road. The four-lane major road with a median width of 9 ft has a design speed of 55 mph. Determine the minimum sight distance required for a passenger car on the minor road to safely turn left onto the major road. The approach grade of the minor road is 5 percent.
A delivery truck passes thru the expressway exit ramps at a design velocity of 50 kph. connects with a local road to allow ram traffic to turn right without stopping at an acceleration of 1.57 m/sq.s. The turning roadway has stabilized shoulders on both sides and provides for a one-lane one-way operation with no provisions for a passing stalled vehicle. Super elevation on the turning roadway is 0.08. Determine the minimum radius of curvature for the ramp in meters.
A 4 lane divided highway with a 12 feet median has a highway grade of -1.5%. The minor road approach grade is 3.5%. The design speed is 45 mph for the major road and 40 mph for the minor road. Find the right turn departure sight distance for a passenger car taking a right turn from the minor road to the major road. Answer should be in feet.
During your internship, your supervisor asked you to design a horizontal curve with a 24-degree deflection angle for a two-lane road with 12-ft lanes. The design speed is 65 mi/h, and superelevation is limited to 4%. The point of intersection (PI) is located at 825+20, and the roadway is on level terrain. Design the horizontal curve.
