- An existing six-lane divided multilane highway with a field-measure free-flow speed of 45mph serves a peak-hour volume of 4,000 vehicles per hour, with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service for this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.An intersection has four symmetrical approaches. The width (curb-to-curb distance) of each approach is 57 ft. If the length of the design vehicle is 19.4 ft and the design speed is 35 mph, what should be the all-red time? Group of answer choices 1.25 sec 1.75 sec 1.50 sec 2.0 secA six-lane freeway (three lanes in each direction) currently operates at maximum LOS C conditions. The lanes are 11 ft wide, the right-side shoulder is 4 ft wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rolling terrain with 10% heavy vehicles, and the peak-hour factor is 0.90. Determine the hourly volume for these conditions in veh/h. Round of your answer to whole number. fLW = 1.9, fRLC = 0.80, PHF = 0.90, N = 3 lanes PT = 0.10, ET = 3.0.
- Draw the intersection diagram for a given traffic volume summary of a T intersection and design the most appropriate and logical phasing pattern for the unsignalized intersection.Estimate the free-flow speed of a six-lane suburban freeway with 12 ft lanes, a right-side lateral clearance of 2ft,and ramp density of 3.5 ramps/mi. Normal conditions, i.e., good weather, no incidences, no work zones, andregular users of the facility, may be assumed.Determine whether a T intersection (one leg on the minor approach) with the hourly volume data satisfy MUTCD Warrant 3 (peak-hr vehicular volume) for signalization. All approaches have one lane entering the intersection. For the warrant that is met, explain how the warrant is met (rules applied, hours in which the volume criteria were met, etc.) and refer to necessary graphs and tables. The major street speed limit is 60 km/h, and the minor street speed limit is 40 km/h.
- (TRAFFIC AND HIGHWAY ENGINEERING) An undivided multilane highway segment has two 11-ft lanes in the eastbound direction with no shoulders and a 55 mi/h speed limit. This highway segment has 40 access points on a 1.25-mile, 2.5% upgrade. During the highest 15 minutes of traffic flow within the peak hour, there are 755 vehicles and 12% of these are heavy vehicles with a 70%/30% mix of single-unit and tractor-trailer trucks. What are the estimated speed, density, and LOS of upgrade?Plz, solve this problem. Transportation Engineering-2 A four-lane highway (2 lanes in each direction) with 3.65m lanes has a horizontal curve designed for a 380 m centerline radius, and a 110 km/hr design speed. The grade is level. Use a driver perception reaction time of 2.5 sec and a vehicle deceleration rate of 3.4 m/sec2. Determine the closest distance any roadside object may be placed to the centerline of the inside lane of the roadway.(note: Do not round any value. Use calculated values).A signalized intersection has two lane groups. The two WBT lanes (lane group #1) have a total volume of 863 pc/h and an average control delay of 24.5 seconds. The one WBL lane (lane group #2) has a volume of 203 pc/h and an average control delay of 36.5 seconds. What is the approach's LOS? Group of answer choices LOS A LOS D LOS C LOS B
- In a given instant, there were 2400 vehicles counted at a specific point along the portion of the TPLEX. The highway was designed to have a capacity of 3000 veh/hr with a free-flow speed of 60 kph. Compute the maximum value of the jam density in veh/km that could possibly occur during heavy traffic assuming linear speed-density relationship applies.A Four Lane freeway is located on rolling terrain with a free flow speed of 70 mph,12ft lanes, and no lateral obstructions within 8 ft of the pavement edges. the traffic stream consists of cars, buses and large trucks (no recreational vehicles) . A weekend directional peak hour volume of 1800 vehicles (*regular users*)is observed ,with 700 arriving in the mostly congested 15 minutes period . if a level of service no worse than C is required ,determine the maximum number of large trucks and buses that can be present in the peak hour traffic stream.. Dislike for wrong answersAnswer True/False to the following: 1) A strong degree of uniformity in the design of traffic facilities guarantees uniform reactions from drivers. 2) The traffic signal warrant that several agencies do not recommend using is the Peak Hour Traffic Volume warrant. 3) It is reasonable to use a higher unit extension time value on an actuated signal approaches with higher speeds. 4) According to the Roundabout Design Guide volume-to-capacity ratio of 0.85 must be the threshold for acceptable operation at a roundabout entry.
