QUESTION 4 A segment of a 4-lane highway is being designed for a FFS of 60 mph through relatively level terrain. The directional (i.e. one-way) design volume is 1,200 vehicles per hour. If 15% of the design volume is expected to be heavy vehicles (i.e. trucks and buses), what is the heavy vehicle adjustment used to determine the flow rate? Provide you answer to the nearest hundredths.
A section of the roadway has the following flow-density relationship q=50k-0.4k^2 [q is in veh/h unit and k in vh/mile]. What is the flow, speed,and density at capacity? What is the density when highway is at one-third of its capacity.
Choose the right answer a rural highway on a level terrain has the following traffic composition: 40 % Passenger cars 30 % trucks 20 % buses 10 % recreational vehicles Find the total volume expressed as pcu/hr. if the total volume is 6000 veh/hr. * a-7620 b-7630 c-7640
A freeway with two northbound lanes is shut down because of an accident. At the time of theaccident, the traffic flow rate is 1200 vehicles per hour per lane and the flow remains at this level.The capacity of the freeway is 2200 vehicles per hour per lane when not impacted by an accident.The freeway is shut down completely for 20 minutes after the accident and then one lane is openfor 20 minutes and finally both lanes are opened (40 minutes after the accident). What is theaverage delay per vehicle resulting from the accident (assuming D/D/1 queuing)?

Calculate the minimum passing sight distance required for a two-lane rural highway that has a posted limit of 72 kph. The local traffic engineer conducted a speed study of the subject road and found the following: Average speed of passing vehicle= 76 kph Average acceleration of passing vehicle= 2.3 kph/sec Average speed of impeder vehicles= 64 kph Show complete solution. Need ASAP. Thank you.
Question 2 Because the new travel time rate (TTR) from the additional traffic (e.g., 300vph) exceeds the minimum acceptable local standard of 2.0 min/mile, it is proposed to increase the road capacity by 900vph/lane by adding one lane in each direction. Calculate the new travel time rate and traffic volume using: a. The traditional method of traffic impact analysis, and b. The above-mentioned pivot point analysis method. c. Compare the results of the two methods and comment on their significance.
V. What is the expected travel speed on a freeway at 1300 pc/h/In and FFS of 75 mph? What is the expected travel speed on a multilane highway at 1400 pc/h/ln and FFS of 55 mph? VI.
