- Which of the following is not a type of freeway section? Basic freeway segment Diverge segment Merge segment Weaving segment None of the above OOO OOOn a proposed highway, the speed limit is 120 km/hr, radius of a horizontal curve on this proposed highway is 250 m and the superelevetion is 8%. Is there any design problem? If so, what the action will you recommend to correct the design?Design a highway with the following criteria (Determine the minimum radius, widening and check if it needs transition spiral) Design speed = 85 kph I = 20o e = 0.06 sight distance = 125m m = 10 m 2 lane road Typical car wheel length 2.5 m Width of pavement per lane = 3.6 m
- Regarding superelevation, when a median is less than 3 m wide, the entire pavement and median may be rotated about the median 01 Centerline 02 Outside edge 3 Inside edge 04 All of the aboveIf a four legged roundabout has 8 conflict points, how many does a 3 legged roundabout? From Highway EngineeringBFS in an eight-lane freeway has two interchanges in six miles along level terrain. The lane width is 11-ft. The left shoulder is 5.0 ft. The right shoulder width is also 5.0 ft. The traffic volume in the analysis period is 3225 veh/h which consists of 14% heavy trucks. Assume PHF is 0.926. What is the LOS? To increase the FFS, the engineer decided to redraw the pavement marking to create four 12-ft lane per direction, with no left shoulder and a 6.0 ft right shoulder. What is the new FFS
- Referring to the vertical curve below, a -2% grade meets a 4.8% grade at the point of vertical intersection (PVI). The vertical curve length is 625 ft. What is the horizontal distance from the low point to PVC?

- Draw a semi cloverleaf interchange, with 2 loop ramps the loop ramps are in the north east and south west quadrantsExit 63 of I-90 includes a tight loop ramp with a radius 250 ft. The advisory exit speed is 30 mph. how much superelevation needs to be provided to allow safe travel on this exit ramp? stay with the same units, I got e = 0.44, just want to double checkIf the weaving configuration below has four lanes and 2000 feet between the ramps, propose the improvements needed to reach an overall level of service of C. Assume a PHF of 0.92, 10% trucks, FFS of 65 mph, lane capacity under ideal conditions of 2,350 pcph and 0.8 interchanges per mile. VFR 1200 VPH = VFF 3000 VPH = VRR = 2300 VPH VRF 1000 VPH
