- A temporary diversion has been constructed on a highway of -3% gradient due to major repairs that are being undertaken. Determine the speed limit that should be imposed on the diversion if drivers can see the sign inform ing them of the diversion at a distance of 400 ft from the diversion and the posted speed limit on the highway is 60 mph.A developer has applied for a construction permit to build a supermarket at the southeast cornerof an intersection that is formed by a four-lane divided highway in the east-west direction and atwo-lane road in the north-south direction. Traffic on the two-lane road is controlled by a stop signat the intersection. The speed limit on the four-lane highway is 88 km/h. using the sight trianglerequirements at the intersection (Case B1), determine whether permission should be given for theconstruction if the following conditions exist. Provide a diagram for your solution.Major road lane width = 3.6 mMinor road lane width = 3.3 mMedian lane = 2.8 mDesign vehicle is a passenger carApproach grade = 2%Maximum feasible distance building from the center of the nearest lane of four-lane road = 5.4 mMaximum feasible distance building from the center of the nearest lane of two-lane road = 16.5 m4. A diversion sign is located 230ft to the diversion point on a 3% down hill road. The road sign can be seen 200ft away by a driver. If the posted speed limit for the road is 65mph, determine the minimum speed limit that can be imposed on the diversion sign
- QUESTION 1 A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.A six-lane freeway (three lanes in each direction in mountainous terrain has 10-ft lanes and obstructions 1ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The traffic stream consists of mostly commuter with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service?A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge.

- QUESTION 5 A segment of rural freeway is being designed for a FFS of 65 mph using 11 ft lanes in a mountainous area. The lateral clearance is nominal (1 ft). The directional (i.e. one-way) design flow rate is expected to be 2,400 passenger cars per hour. How many lanes in one direction will be needed to provide at least a LOS B?Determine the PTSF in each direction for a 4.5 mi (7.2 km) two-lane highway segmentin level terrain. Traffic volumes (two-way) are 1100 veh/h. Trucks: 10%; RVs: 7%; PHF:0.97; directional split: 60/40; no passing zones: 40%.when desiging an auxiliary lane, the deceleration length need to be determined. Briefly explain what is the deceleration length and how to determine it
