A road with a design speed of 55 mph has a utility pole located 27 ft from the edge of travel lane. If the ADT for the road is 1,850 vpd and the sideslope slopes down at a 1V:4H grade, is the utility pole located within the clear zone?
Two passenger cars are traveling at 88.5 kph. The weight of car A is 9000 N and that of car B is 18000 N. The cross-sectional area for car A is 3.15 m2 and that for car B is 3.6 m2. Both cars travel on a straight and level section of road. Determine the grade resistance for car B in Newton.
A vehicle initially traveling at (75 mile/hr.), skids to a stop taking (170) m to do so. the coefficient of skidding resistance (0.36). What should the grade be for this roadway. (Use t = 2.5 sec.).
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.
Subject : Transportation Engineering Read the question carefully and give me right solution according to the question. A two lane-two way highway 7.5 m wide with a right-turn curve. The design speed is 100 kph and the difference in elevation between the edges of the fully super-elevated cross-section is 0.45 cm. Determine the setback of a building corner required for satisfying safe stopping sight distance.
A vertical curve was designed in 2006 for SSD requirements at a design speed of 120 km/h to connect grades G1 = +1% and G2 = -2%. The curve is to be redesigned for 120 km/h design speed in the year 2050. Vehicle braking technology has advanced such that vehicle deceleration rate has increased by 40% relative to 3.4m/s2 value used in the original design. However, due to the higher percentage of older people in the driving population, design reaction times have increased by 20%. Also, because vehicles have become smaller, the driver’s eye height is assumed to be 0.9 m above pavement. Compute the difference in design curve lengths for the 2006 and 2050 designs. Assume heye =1.08 and hobs = 0.60 m.
During peak periods, “Trotro” drivers use the shoulders as travel lanes on the section of the Kasoa road approaching the toll booth from the West Hills Mall direction. As a Highway Engineer, what design intervention would you propose to prevent the shoulders from being used as travel lanes during congested period or as part-time shoulders but still function as shoulders?

The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths.
The 3 eastbound lanes of a rural freeway segment have 11 ft lane widths. There is a 3 ft lateral clearance on the right side of the road. There are no ramps within the influence area. What is the estimated FFS (mph)? Provide your answer to the nearest tenths.
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.
The C-5 Southlane Freeway/Expressway having 6 lanes (three lanes in each direction) is 3.6m wide per lane and has an edge distance of 2 m to the nearest obstruction. A total of 26 on-or off-ramps within the 40 km span, from which 3 ramps are located within 5 km upstream and 4 ramps within 5 km downstream from the midpoint of the analysis segment can be observed. Determine the free-flow speed of the existing freeway, in kph. Do not round-off your FFS
What super-elevation rate would you recommend for a roadway with a design speed of 110 kph and a radius of 1400 ft? Assume f=0.11.
