A suburban undivided 50 km multi-lane highway on rolling terrain has an AADT of 30,000 vehicles per day, with a peak hour factor estimated at 0.9 and the directional factor, D is estimated at 0.7. All lanes are 3.05 m wide. There are no obstructions within 1.83 m of the curb. The percentages for the various heavy vehicle types are PT – 12%, PB – 6%, PR – 2%. The highway is required to provide a Level of Service ‘B’. Assuming (refer to TRB1994) the highway is to be designed for the thirtieth highest hourly volume during the year (where K = 0.15).

A six-lane freeway operates at capacity during the peak hour. It has 10-ft lanes, 4.3-ft shoulders, and there are 4 ramps within 3 miles upstream of the segment midpoint and 4 ramps within 3 miles downstream of the segment midpoint. The freeway is on rolling terrain and has 8% heavy vehicles with a peak-hour factor of 0.90. It is known that 12% of the AADT occurs in the peak hour. The AADT is 50,400 veh/day. What is the directional factor?
A four-lane freeway (two lanes in each direction) operates at capacity during the peak hour. It has 11-ft lanes, 4-ft shoulders, and there are three ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has only regular users, there are 8% large trucks and buses (no recreational vehicles), and it is on rolling terrain with a peak-hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the directional factor is 0.6. What is the freeway’s AADT?
A six-lane divided highway (three lanes in each direction) is on level terrain with 6 access points per kilometer and has 3.6-m lanes, with a 1.2-m shoulder on the right side and a 0.6-m shoulder on the left side. The peak-hour factor is 0.80, and the directional peak-hour volume is 3,500 vehicles per hour. There are 5% large trucks and 3% recreational vehicles. A significant percentage of non-familiar roadway users are in the traffic stream (the driver population adjustment factor is estimated as 0.85). No speed studies are available, but the posted speed limit is 80.5 km/h. Determine the level of service.
traffic engineering - Q / A freeway is being designed to carry a heavy volume of 5000 veh / h on a regular weekday in rolling terrain . If the PHF is 0.9 and the traffic consists of 90 % passenger cars and 10 % trucks , determine the number of 12 - ft lanes required in each direction if the highway is to operate at level of service C. The free - flow speed is 70 mi / h , there is no lateral obstruction , and interchanges are 3 mi apart .
A two-lane rural roadway segment is expected to have 15 crashes (total) durch year with AADT of 1800 veh/day. The current width of the lane is 10 ft. It is prop width of the lane be increased to 12 ft. What should be expected number of crashes (total) the new condition?
A car hits a tree at an estimated speed of 32 mph on a 3% downgrade. If skid marks are observed for a distance of 130 feet on a dry pavement (a= 15.5 feet/sec2), followed by 210 feet on a grass-stabilized shoulder (a= 7.6 feet/sec2), estimate the initial speed of the vehicle.
A 2-lane highway has lane widths of 2.75m, with 1.83m clear hard shoulders. There are no-passing zones along 40% of its length. The directional split is 60/40 in favour of the peak direction. The percentages of the various heavy vehicles types are: Trucks PT – 10%, Buses PB – 4%, Cars Pc – 2%. The terrain is rolling; calculate the service flow of the highway when running at full capacity
A vehicle initially traveling at (75 mile/hr.), skids to a stop taking (170) m to do so. the coefficient of skidding resistance (0.36). What should the grade be for this roadway. (Use t = 2.5 sec.).
Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?
A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 3.5m wide, the right-side shoulder is 1.2 m 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% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. a) Determine the hourly volume for these conditions. b) At one point along this freeway, there is a 4% upgrade with a directional hourly traffic volume of 5000 vehicles. How long can this grade be without the freeway LOS dropping to F?
During the peak hour on a Class I two-lane highway, volumes northbound are 1200 veh/h and volumes southbound are 400 veh/h. The PHF is 0.95, and there are 14% trucks/ buses and 4% RVs. Lane widths are 3.35 m, and shoulder widths are 1.2-m. The roadway section is 8-km in length, and there are 12 access points per mi. There are 50% no-passing zones and the base free-flow speed is 96 km/h. Determine the base percent time following in the direction analyzed in percent. Assumc Level terrain.
A four-lane freeway with the following characteristics: ten foot travel lanes lateral obstructions at 0 feet at the roadside total ramp density is 4.5 ramps/mile rolling terrain The roadway has a current peak demand volume of 3500 veh/h. The peak hour factor is 0.95 and there are no trucks, buses, or RVs in the traffic stream because the roadway is classified as a parkway and such vehicles are prohibited. At what level of service will the freeway operate during its peak period of demand?
