Question 1
A level highway has a design speed of 50 mi/h. Using a perception-reaction time of 2.5 s and a deceleration rate of 11.2 ft/s², the stopping sight distance is about:
- A240 ft
- B314 ft
- C424 ft
- D664 ft
Show answer and explanation
Answer: C) 424 ft
Stopping sight distance is reaction distance (1.47Vt) plus braking distance (1.075V²/a): 184 ft + 240 ft ≈ 424 ft.
- AIncorrect. This is only the braking distance, V²/(2a) = 73.5²/(2 × 11.2) ≈ 240 ft. It leaves out the roughly 184 ft travelled during the perception-reaction time.
- BIncorrect. This uses a 1.0-s perception-reaction time (about 74 ft) instead of the given 2.5 s. The braking distance of 240 ft is right, but the reaction distance is too small.
- CCorrect. Reaction distance = 1.47(50)(2.5) ≈ 184 ft. Braking distance = 1.075V²/a = 1.075(2,500)/11.2 ≈ 240 ft. SSD ≈ 184 + 240 ≈ 424 ft.
- DIncorrect. This computes braking distance as V²/a (≈ 480 ft) and drops the factor of 2 in V²/(2a), so the braking part comes out twice as large.
Question 2
A toll booth receives 600 veh/h and can serve 900 veh/h. The utilization is:
- A300 veh/h
- B1.5
- C0.33
- D0.67
Show answer and explanation
Answer: D) 0.67
- AIncorrect. That's spare capacity.
- BIncorrect. That's inverted.
- CIncorrect. That's the idle fraction.
- DCorrect. ρ = λ/μ = 600/900.
Question 3
Under ideal conditions, the capacity of a basic freeway lane is about:
- A600 passenger cars per hour per lane
- B2,400 passenger cars per hour per lane
- C10,000 passenger cars per hour per lane
- D1,000 vehicles per day per lane
Show answer and explanation
Answer: B) 2,400 passenger cars per hour per lane
- AIncorrect. That's far too low.
- BCorrect. Capacity varies with free-flow speed.
- CIncorrect. That's far too high.
- DIncorrect. That's a daily volume.
Question 4
Speed 60 mi/h, perception-reaction time 2.5 s, f = 0.35, level grade. The stopping sight distance is about:
- A563 ft
- B343 ft
- C221 ft
- D783 ft
Show answer and explanation
Answer: A) 563 ft
- ACorrect. \(1.47(60)(2.5) + 60^2/[30(0.35)] = 220.5 + 342.9\).
- BIncorrect. That's braking distance only.
- CIncorrect. That's reaction distance only.
- DIncorrect. Recheck the braking term.
Question 5
The Pavement Condition Index (PCI) rates pavement condition on a scale of:
- AA to F
- B1 to 5, like a star rating
- C0 to 10
- D0 to 100
Show answer and explanation
Answer: D) 0 to 100
- AIncorrect. That's level of service.
- BIncorrect. PCI uses 0 to 100.
- CIncorrect. PCI uses 0 to 100.
- DCorrect. 100 is excellent.
Question 6
In pavement design, an ESAL is the damage equivalent of one pass of a:
- APassenger car
- BFully loaded 80-kip tractor-trailer
- C18-kip single axle load
- D10-kip tandem axle
Show answer and explanation
Answer: C) 18-kip single axle load
- AIncorrect. It's an 18-kip single axle.
- BIncorrect. It's an 18-kip single axle.
- CCorrect. Equivalent single axle load.
- DIncorrect. It's an 18-kip single axle.
Question 7
Design speed 50 mi/h, radius 1,000 ft, side friction factor 0.12. Using \(e + f = V^2/(15R)\), the required superelevation is about:
- A0.047
- B0.167
- C0.120
- D0.287
Show answer and explanation
Answer: A) 0.047
- ACorrect. \(2{,}500/15{,}000 - 0.12 = 0.167 - 0.120\).
- BIncorrect. Subtract the side friction factor.
- CIncorrect. That's the friction factor.
- DIncorrect. Subtract f, don't add it.
Question 8
A conventional four-leg intersection with two-way approaches has how many vehicle conflict points in total?
- A8
- B16
- C32
- D4
Show answer and explanation
Answer: C) 32
- AIncorrect. That's a roundabout's total.
- BIncorrect. That's the crossing conflicts only.
- CCorrect. 16 crossing, 8 merging and 8 diverging.
- DIncorrect. Recheck the count.
Question 9
A 3,000-lb car climbs a 5% grade. The grade resistance force is about:
- A60 lb
- B1,500 lb
- C150 lb
- D300 lb
Show answer and explanation
Answer: C) 150 lb
- AIncorrect. That isn't the calculation.
- BIncorrect. That's off by a factor of 10.
- CCorrect. Weight × grade.
- DIncorrect. That doubles it.
Question 10
A 10-mile trip at an average speed of 40 mi/h takes:
- A40 minutes
- B25 minutes
- C4 minutes
- D15 minutes
Show answer and explanation
Answer: D) 15 minutes
- AIncorrect. Recheck the division.
- BIncorrect. Recheck the division.
- CIncorrect. That's inverted.
- DCorrect. 10/40 h = 0.25 h.
