A six-lane divided highway (three lane in each direction) is on rolling terrain with two access points per mile and has 10-ft. lanes, with a 5-ft. shoulder on the right side and a 3-ft. shoulder on the left side. The peak-hour factor is 0.80, and the directional peak-hour volume is 3000 vehicles per hour. There are 6% large trucks, 2% buses, and 2% recreational vehicles. A significant percentage of nonfamiliar roadway users are in the traffic stream (the driver population...

6.28 A multilane undivided highway is on level terrain and has two lanes in the northbound direction. The posted speed limit is 55 mi/h and there are 11-ft lanes, 3-ft right shoulders, and 8 access points per mile. The highway operates at capacity during the peak hour with 20% heavy vehicles and a peak-hour factor of 0.925. What is the peak-hour demand volume?

Exercise 1 [I8 pts]. Two lanes of a three-lane highway are closed because of road works on a 2 km long segment. A detector placed on one single lane in the undisturbed zone upstream the road works detects a flow of 2,000 veh/h and an average speed of 100 km/h. A second detector placed on one of the two lanes just upstream the roadwork zone detects a flow of 800 veh/h and an average speed of 40 km/h. We observe...

A horizontal curve forms part of a four-lane highway that has a posted speed limit of 40 mph. The lane width is 12 ft and the radius of the horizontal curve equals 1000 ft at the highway centerline. Determine the minimum distance a large billboard can be placed from the centerline of the inside lane of the curve, without reducing the required stopping sight distance. (Use default values of reaction time and vehicle deceleration).

3-25 Calculate the minimum passing sight distance required for a two-lane rural roadway that has a posted speed limit of 45 mi/h. The local traffic engineer conducted a speed study of the subject road and found the following: average speed of the passing vehicle was 47 mi/h with an average acceleration of 1.43 mi/h/sec, and the average speed of impeder vehicles was 40 mi/h.
