Subject: transportation engineering Read the question carefully and give me right solution according to the question. A signal has four phases, where the critical lane group flow ratios are 0.115, 0.204, 0.099, and 0.248. If the lost time per phase is 6 seconds and the critical intersection v/c ratio is 0.88, calculate the minimum cycle length and the phase effective green times such that the lane group v/c ratios are equal.
A signalized intersection has two lane groups. The two WBT lanes (lane group #1) have a total volume of 863 pc/h and an average control delay of 24.5 seconds. The one WBL lane (lane group #2) has a volume of 203 pc/h and an average control delay of 36.5 seconds. What is the approach's LOS? Group of answer choices LOS A LOS D LOS C LOS B
Studies have shown that the traffic flow on a two-lane road adjacent to aschool can be described by the Greenshields model. A length of 0.5 miadjacent to a school is described as a school zone and operates for a periodof 30 min just before the start of school and just after the close of school.The posted speed limit for the school zone during its operation is 15 mi/h.Data collected at the site when the school zone is not in operation showthat the jam density and mean free speed for each lane are 125 veh/mi and57 mi/h. If the demand flow on the highway at the times of operation ofthe school zone is 90% of the capacity of the highway, determine: The speeds of the shock waves created by the operation of the schoolzone, and• The number of vehicles affected by the school zone in the upsream ofthe zone during this 30-minute operation.

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)?
1. A study of freeway flow at a given site has yielded a relationship speed-density calibrated as follows: S = 57,5(1 - 0,008 D) For this relationship, specify: (a) free flow velocity, (b) congestion density, (c) velocity-flow relationship (d) flow density relationship, and (e) capacity. 2.

Q3b. The 15km Atta Mills road connecting Old Barrier to Kokrobite operates with a capacity of 2250 pcu/hr and can be traversed within 15 minutes under free flow conditions. If a flow of 3100 pcu/hr is assigned to the road based on the capacity-restrained approach, what would be the resultant travel time after the traffic assignment proce ss.
Flow on a freeway with two lane was 1600 veh/hr/ln, and the density of 16 veh/km/ln. Due to maintenance work on the left side of the road, 12 km of the road were closed, there was increasing in density to be 29.8 veh/km/ln and backward moving shockwave speed with 8 km/hr. 1. Find the speed and flow of the right side in the maintenance section. 2. How many vehicles (per lane) will be in the platoon after leaving the work zone?
The minimum cycle length for an intersection is determined to be 95 seconds. The cirtical lane group flow ratios were calculated as 0.235, 0.250, 0.170 and 0.125 for phases 1- 4 respectively. What Xc was used in the determination of this cycle length, assuming a lost time of 5 seconds per phase?
