QUESTION 3 What is the intersection sight distance (ft) needed at a yield controlled intersection for a passenger car to turn left onto a 2- way, 2-lane road with a design speed of 50 mph? [round to the nearest foot]
a) A lane merge warning sign (shown below) is being installed near an entrance ramp on a freeway with operating speeds of 80 mph. Calculate the appropriate advance placement distance (to the nearest foot) for the sign assuming a perception-reaction time of 14 seconds for the vehicle avoidance maneuver. b) A curve or turn warning sign is to be installed near a single curve with a 28 mph design speed (per ball-bank indicator) on a rural 2-lane roadway. The prevailing speed of traffic on the approaching tangent section is 62 mph. Calculate the advance placement distance upstream of the curve PC for this sign (to the nearest foot). Also indicate the appropriate sign to be used (curve or turn) and the appropriate safe advisory speed if one is to be posted for this curve.
A traffic signal control is being designed for a four-leg intersection on a divided highway with the characteristics shown in the table below. Assuming the average vehicle length L is 6m, Determine an appropriate length of the yellow interval for each approach and how you will provide it. Use the AASHTO recommended deceleration rate and perception-reaction time.

QUESTION 4 What is the intersection sight distance (ft) needed at a yield controlled intersection for a passenger car to turn right onto a 2- way, 2-lane road with a design speed of 50 mph? [round to the nearest foot]
P Flag question The following field data were collected on a two-way road using the moving vehicle method. The vph. (MN = 120, Ms = 110, ON = 7, PN= 8, TN = 0.042 hr., Ts = traffic volume northbound (qn) is 0.048 hr.). а. none b. 1211 C. 1312 d. 910 е. 1566
Problem 3 (30%) Problem 11-1 in Roess, Prassas, McShane, 5th ed. (edited - omit part f) Consider the spot speed data below, collected at a rural highway site under conditions of uncongested flow: Speed Group (mi/h) Number of Vehicles Observed (N) 15-20 0 20-25 4 25-30 9 30-35 18 35-40 35 40-45 42 45-50 32 50-55 20 55-60 9 60-65 0 a. Plot the frequency and cumulative frequency curves for this data. b. Determine the median speed, the modal speed, the pace, and the percentage of vehicles in the pace from the curves and show how each was found. c. Compute the mean and standard deviation of the speed distribution. d. What are the confidence bounds of the estimate of the true mean speed of the distribution with 95% confidence? With 99.7% confidence? e. Based on the results of this study, a second study is to be conducted to achieve a tolerance of ±0.8 mi/h with 95% confidence. What sample size is required?
Observers stationed at two sections XX and YY, 1000 ft apart on a highway, record the arrival times of four vehicles as shown in the table below. Vehicle Section XX Section YY A T0 T0 + 14.33 sec B T0 + 3.76 sec T0 + 18.14 sec C T0 + 7.94 sec T0 + 22.06 sec D T0 + 12.13 sec T0 + 27.87 sec If the total time of observation at XX was 20 sec, determine (a) the time mean speed, (b) the space mean speed, (c) the flow at section XX, and (d) the density on the highway
