Scheduled maintenance will close two of the four westbound lanes of a freeway during one weekday for the period from 9:00 AM to 4:00 PM. The demand on the two lanes are as follows: Time Demand, vph 9:00-10:00 AM 4000 10:00-11:00 AM 3500 11:00-12:00 NN 2500 12:00-1:00 PM 2000 1:00-2:00 PM 2000 2:00-3:00 PM 2000 3:00-4:00 PM 2000 If the estimated capacity of the 4 lanes with 2 lanes open is 2960 vph, a. compute the time when maximum queue occurs. 11:00 AM b. compute the maximum queue formed. 1580 vehicles c. compute the maximum length of queue if the average length of cars is equal to 5 meters. 1975 m Show all necessary diagrams and solutions.

(show your solutions) Given the figure above, compute for the Annual Average Daily Traffic of all vehicle types: * A.338 B.None of the above C.393 D.418 E.431
2) Given the following data for five traffic analysis zones (TAZ): Zone Production Attraction 1 1 2 4 The travel times are as follows: 5 13 min 20 min 15 min 450 600 270 325 0 9 min 7 min 5 min 3 400 750 120 0 350 Determine the trips on the following: T1-3 and T2-5.
2. There are two routes in use between Zones 1 and 2. The volume-delay functions for the two routes are as follows: V1 V2 t1 = 22 + 250 t2 = 15 + 150 where t = travel time(minutes) V = traffic volume If the total traffic volume is 6,950 vehicles per hour between the two zones, what are the traffic volumes and travel times on each of the two routes at a user-equilibrium (UE) condition?
Consider the freeway and traffic conditions described in Problem 6.3. If 180 of the 1800 vehicles observed in the peak hour were large trucks and buses, what would the level of service of this freeway be on a 5-mi, 6% downgrade?
with central reserve the current traffic in 2019 expressed by AADT is 3000 vehicle in both direction. the improved road with design life traffic 20 years will be opened to traffic in 2024. The estimated annual growth rate of traffic is 5%. 1000pcu/hr 12% f ADT 60% of total volume 16% of hourly volume Lane capacity K D Th Q1-B:1-How are travel time and delay studies used?
4. Three routes connect and origin and a destination with performance functions t₁ = 8 + x₁, t₂ = 1 + 2x₂, and t3 = 1 + 0.5x3 (with x's in thousands of vehicles per hour and t's in minutes). If the peak-hour traffic demand is 3400 vehicles, determine user- equilibrium traffic flows on each route. [Ans: x₂ = 0.68]
5- Traffic volume study was conducted in a section of road in month of April the following information's was obtained ( HEF=18, POV =650 veh/h, total weekly volume =72450 veh/week, total yearly volume = 23770 veh lyear, MEF =1/2 DEF). So, the ADT of this month? (Assume total daily volume = average daily volume) * O 7923 veh 850 veh 660 veh O 1240 veh
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.
It is estimated that after 25 years in a section of highway, the average daily traffic will be 15000 vehicles. It is found that ratio of design hourly volume to the average daily traffic was 15%. The one way traffic volume in the predominant direction is 60% of the two way design hourly volume. Determine the directional ?design hourly volume after 25 years **
The daily counts of the current traffic volume for a rural highway for one week of May 2000 are as shown in the following table: Sat. Sun. Mon. Tues. Wed. Thur. Fri. Day Daily volume 12000 12500 10500 11500 9500 9000 8500 The traffic is composed of 70% passenger car, 20% bus, 10% truck. The percent of future traffic to current traffic is predicted to be 180% up to May 2020. Determine the required number of lanes for this highway if the lane capacity is 1300 pc/hr.
