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

A traffic signal control is being designed for a four-leg intersection on a divided highway with the characteristics shown in the table below. Assuming the average vehicle length L is 6m, Determine an appropriate length of the yellow interval for each approach and how you will provide it. Use the AASHTO recommended deceleration rate and perception-reaction time. N-S Approaches E-W Approaches Median width, (m) 6. 3 No. of 3.5 lanes 3 on each approach Design speed, km/h 60 Grade -3.5 2. 80

Problem-Traffic Engg. A two-phase signalized intersection is designed with a cycle time of 120 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)

A two-phase signalized intersection is designed with a cycle time of 100 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)

How many diverging conflicts are present at a 4-leg intersection where each leg is a single lane approach, as shown above? Response Feedback: NBTH with NBLT, NBTH with NBRT EBTH with EBLT, EBTH with EBRT SBTH with SBLT, SBTH with SBRT WBTH with WBLT, WBTH with WBRT

10. For the intersection shown below draw a 3-phase traffic signal operation.

An intersection has four symmetrical approaches. The width (curb-to-curb distance) of each approach is 57 ft. If the length of the design vehicle is 19.4 ft and the design speed is 35 mph, what should be the all-red time? Group of answer choices 1.25 sec 1.75 sec 1.50 sec 2.0 sec

A turning movement count and a saturation flow study were conducted at a major intersection on an expressway with configuration as presented in Fig.1. The peak-hour volumes and saturation flows obtained from the studies for each movement are presented in Tables 1 and 2, respectively. i) provide a diagrammatic representation of the signal sequence at the intersection. Assume a yellow interval of 3s, all-red interval of 2s and a peak hour factor of 0.95 for all the approaches. Note: No two movements should conflict during the determination of the phasing plan.
