Determine whether a T intersection (one leg on the minor approach) with the hourly volume data satisfy MUTCD Warrant 3 (peak-hr vehicular volume) for signalization. All approaches have one lane entering the intersection. For the warrant that is met, explain how the warrant is met (rules applied, hours in which the volume criteria were met, etc.) and refer to necessary graphs and tables. The major street speed limit is 60 km/h, and the minor street speed limit is 40 km/h.
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?

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.arrow_forwardA poorly timed signal or one that is not justified can have a negative impact on the opration of the intersection because it (CHOOSE ALL THAT IS APPLICABLE) Choices: A.

- Answer the following: True/False: Adjusting the yellow interval at an intersection may be used to address dilemma zone at a signalized intersection approach. True/False: Using a peak hour factor of 0.95 or higher when determining critical cycle length ensures that during peak hour there is as little unused green time as possible. True/False: Traffic treatment of channelized right turns is not addressed in the HCM as a deterministic treatment. True/False: MUTCD traffic signal warrant provide option for using lower volume thresholds for signalizing intersections in isolated rural communities.arrow_forwardA signalized intersection approach has two lanes with no exclusive left- or right-turning lanes.
