Computing the Capacity of a Signalized Approach. The eastbound approach of a signalized intersection with a cycle length of 80 sec gets 37 sec of green. Studies show that the saturation headway for that approach is 2.2 sec, the start-up lost time is …

Question: 17. A signalized intersection approach has an upgrade of 4%. The total width of the cross street at this intersection is 18 m. The average vehicle length of approaching traffic is 4.8 mt. The speed of approaching traffic is 64 km/h. Determine the minimum length of necessary change and clearance intervals. 18.

A signalized traffic signal has flow ratios of 0.385 and 0.392 for lane groups in Phase 1. The critical flow ratio is ____.

Question: Question 2: A signalized intersection approach operates at an effective v/c ratio of 1.05 for a peak 30-minute period each evening. If the approach has a g/C ratio of 0.6 and the cycle length is 75 secondsthen assuming saturation headway as 2.8 sec/veh: (50 points)a) What is the average control delay during the ...

A signalized intersection has four phases. The yci are 0 . 1 5 , 0 . 1 9 , 0 . 2 1 , and 0 . 1 7 for the four phases, respectively If the cycle length is 1 0 8 seconds and the total lost time is 1 6 seconds, what is the effective green time for phase

Question: QUESTION 19The WBL lane group of a signalized intersection has an average control delay of 33.5 seconds. What is the LOS for the WBL lane group?  LOS A  LOS B  LOS C  LOS D

Three signal phases will be designed for a signalized intersection. The volumes (V) and saturation flows (s) of the critical lane group for all the phases are listed below. Assume that each phase loses 3 seconds. Apply the Webster formula to calculate the optimum cycle length. (Round Up to the nearest second and fill in the blank with a number ...

7. (1.5 points) A four-leg signalized intersection has an AADT of 10,000 on the major road and 5,000 on the minor road. Do you recommend switching to a roundabout (Will a roundabout reduce the number of crashes?)? N s p f, 4 SG = e − 5.13 AA D T major 0.61 AA D T minor 0.20 N s p f, R A = e − 6.07 AA D T all 0.749

At a signalized intersection, one lane is observed to discharge 40 through vehicles in the same time as the left lane discharges 10 through vehicles and 20 left-turning vehicles. For this case: What is the through-vehicle equivalent, ELT, for left-turning vehicles? What is the left-turn adjustment factor, fLT, for the case described?

Traffic on the eastbound approach of a signalized intersection is traveling at 3 3 mi / h, with a density of 4 3 veh / mi / ln. The duration of the red signal indication for this approach is 3 0 sec. If the saturation flow is 1, 9 0 0 veh / h / ln with a density of 4 9 veh / mi / ln, and the jam density is 1 2 8 ...
