Question 2. A segment of a two-lane high in Class 1 is on a rolling terrain and has an hourly volume of 1000 veh/h. This value is for both directions. The directional traffic split is taken as 60/40 and the peak hour factor is assumed to be 0.92. Asides the passenger cars, the traffic stream contains 6% large trucks, 3% buses and 6% recreational vehicles. (a) Determine the analysis direction flow rates for ATS and PTSF (2.5 marks) (b) Determine the opposing direction flow rates for ATS and PTSF (2.5 marks)

Tubibi Highway is a Class II Two-lane highway that is considered a level terrain. Based on the data, 1,631 passenger cars travel on average per hour for both directions with a directional split of 50/50. A maximum of 388 passenger cars is recorded within a 15-min time segment of the peak hour. The traffic stream contains 2% large trucks, 3% buses, and 3% recreational vehicles. Determine the opposing direction flow rate in pc/hr. Answer in two decimal places. 2,953.65 776 margin of error +/- 0.5
A portion of the extension of SLEX has a free flow speed of 60kph and a capacity of 3600 veh/hr. If in a given hour, 3344 vehicles were countered at a specified point along this highway, determine the traffic density of these 3344 vehicles.
Eight lane urban freeway is on level terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of unfamiliar road users. Peak hour volume for a directional weekday of 3200 vehicles is observed with 900 vehicles arriving in the most congested 15-min period. If the traffic stream has 20% large trucks and 20% buses and 15% recreational vehicles, determine the exact demand flow rate (in pc/h/In). Round your answer to 3 decimal places. Exclude the unit in the answer box.
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..

A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 8% heavy vehicles. If the peak-hour factor is 0.85, determine the highway’s level of service. Answer: LOS:C
A freeway is to be designed as a passenger-car-only facility for an AADT of 35000 vehicles per day. It is estimated that the freeway will have a free flow speed of 70mph. The design will be for commuters and the peak hour factor is estimated to be 0.85 with 65% of the peak hour traffic traveling in the peak direction. If the k-factor for this freeway is 0.148, determine the directional design hourly volume. 3367 4403 2862 5015
Traffic volume count has been collected on a 2- lane road section which needs upgradation due to severe traffic flow condition. Maximum service flow rate per lane is observed as 1280 veh/h at level of service 'C'. The Peak Hour Factor is reported as 0.78125. Historical traffic volume count provides Annual Average Daily Traffic as 12270 veh/day. Directional split of the traffic flow is observed to be 60: 40. Assuming that traffic stream consists of 'All Cars' and all drivers are 'Regular Commuters', the number of extra lane(s) (round off to the next higher integer) to be provided, is
There are 9 vehicles observed in a 300 m section of McArthur highway. If the average time headway is 4 sec., compute the space mean speed of the vehicles in kph.
Assume you are observing traffic in a single lane of McArthur Highway at a specific location. You measure the average headway and average spacing of the vehicles as 3.2sec. and 50 m. respectively. Determine the traffic flow in vehicle/hour.
Problem 2: A Class III two-lane highway is on level terrain, has a measured free-flow speed of 45 mi/h, and has 100% no-passing zones. During the peak hour, the analysis direction flow rate is 150 veh/h, the opposing direction flow rate is 100 vehh, and the PHF = 0.95. There are 5% large trucks and 10% recreational vehicles. Determine the level of service.
Q- Traffic volume count has been collected on a 2-lane road section which needs upgradation due to severe traffic flow condition. Maximum service flow rate per lane is observed as 1280 veh/h at level of service "C". The Peak Hour Factor is reported as 0.78125. Historical traffic volume count provides Annual Average Daily Traffic as 12270 veh/day. Directional split of the traffic flow is observed to be 60:40. Assuming that traffic stream consists of "All Cars' and all drivers are Regular Commuters', the number of extra lane(s) (round off to the next higher integer) to be provided, is
