- Question 4 One stretch of two-lane two-way roadway that traverses through level terrain is expected to carry 1400 vehicle per hour. Determine the Level of Service (LOS) in the peak direction for the road based on average travel speed (ATS) if the characteristics of the roadway are as follows: Table Q4-1 Percentage of Trucks Percentage of Recreational Vehicle Peak Hour Factor 10 0.97 60:40 60 Percent Directional Split Percent no-passing Zone Lane Widths Shoulder Widths Design Speed Road Length Access Points 3.35 m 1.2 m 96 km/h 8 km 10 access points per km State all assumption (if any) used in calculation..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 +/- 0.5There 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.
- A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?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.B- A traffic count was conducted to a rural highway if the peak 15 mints 800 vehicles and peak hourly factor (PHF) 0.95 the directional distribution (35:65)% and traffic composition is 75%p.c and 25%truck, 1-Estimate the number of lanes required ?

- 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:CA freeway with flow rate ( VP ) = 1600 Pc/hr./In. and free flow speed = 55 %3D mile/hr. the recommended level of service ( LOS ) when you drop on Figure is: * O LOS A LOS D O LOS B LOS C LOS FA 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
- 1- You are assigned to evaluate the level of service for a section of a six-lane rural highway that stretches along a level terrain with shoulder width of eight ft and lane width of twelve ft. The average annual daily traffic is fifty-five thousand vehicles per day with ten percent trucks, five percent buses, and three percent recreational vehicles. The peak hour factor is 0.80 and the directional split is fifty-fifty. The distance between consequent interchanges is two miles. Calculate the level of service for this highway section and show your calculation steps.A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The traffic stream consists of mostly commuters with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service?
