Please read the question carefully and give me right solution. Subject : Transportation engineering Given below is an intersection and respective flows for every movement (per lane). The intersection is programmed to operate in two phases: Phase 1 (EB, WB) and Phase 2 (NB, SB). What is the critical lane flow for Phase 2?
A section of Texas Highway 83 (Tx83) has a free-flow speed of 55 mph and a capacity of 3,300 vehicles per hour. At 8 am, 2,100 vehicles were counted using a 6 ft by 6 ft inductive loop. If the linear speed-density relationship applies, what is the estimated space-mean speed of these vehicles?

2.) Daily Traffic Expansion Factors A student measured the traffic volume of a rural primary road for five hours on a Wednesday for a project. The data is summarized below: Time Volume 7:00 – 8:00 AM 200 8:00 – 9:00 AM 325 9:00 – 10:00 AM 410 10:00 – 11:00 AM 503 11:00 – 12:00 AM 385 a) Determine the 24-hour volume for that day. Unit: veh. /day b) Determine the average daily traffic for the week unit: veh. /day Listed/Shown in the images are the expansion factors given.
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.

1. The following data has been collected at a point along highway. Determine the Peak Hour Lane Volume (PHV). Also find out Peak Hour Factor based on 15 minutes and Peak Hour Factor based on 5 minutes Time Interval Time Interval 4:30-4:35 pm 4:35-4:40 pm 4:40-4:45 pm 4:45-4:50 pm 4:50-4:55 pm 4:55-5:00 pm 5:00-5:05 pm 5:05-5:10 pm 5:10-5:15 pm 5-min Lane Volume 120 167 130 135 165 130 149 170 155 5:15-5:20 pm 5:20-5:25 pm 5:25-5:30 pm 5:30-5:35 pm 5:35-5:40 pm 5:40-5:45 pm 5:45-5:50 pm 5:50-5:55 pm 5:55-6:00 pm 5-min Lane Volume 178 140 135 172 150 178 154 170 145
Note: Draw relevant graph also.
Consider the following data: • Average number of vehicles (overtaking - overtaken) = 1 • Average number of vehicles during trips in opposite direction of traffic flow = 336 • Average journey time when test vehicle is travelling with the stream = 8 min 31 sec. • Average journey time when test vehicle is travelling against the stream = 7 min 24 sec. Average journey time for the above data is min.
It is known that the capacity is 3800 veh/h and the jam density is 225 veh/mi. What is the space-mean speed of the traffic at capacity, and what is the free-flow speed? if chart or graph was used please attaxch below and explain how its used
