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
3. An intersection approach has two lane groups: left-turn lane group, and through/right-turn lane group. The control delay is 37 seconds/vehicle for the left-turn lane group, and 27 seconds/vehicle for the through/right-turn lane group. The analysis flow rate is 97 vehicles/hour for the left-turn lane group, and 450 vehicles/hour for the through/right-turn lane group. Calculate the approach control delay and write the corresponding level of service (LOS) for the approach in the box below.

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.
TRANSPORTATION ENGINEERING-TRAFFIC SIGNALS" Recent analysis at an approach to pre-time signalized intersection indicate that the volume-to-capacity ratio (v/c) is 0.8, htat saturation flow rate (s) is 1600 vehicles/hour, and the effective green time is 50 seconds. If the average delay, assuming D/D/1 is 11.25 seconds per vehicle, determine the arrival flow rate (vehicles/hour) and the cycle length.

An intersection has a three-phase signal with the movements allowed in each phase and corresponding analysis and saturation flow rates shown in the table below. (1) Calculate the sum of the flow ratios for the critical lane groups. (2) calculate the minimum cycle length and the effective green time for each phase (balancing v/c for the critical lane groups). Assume the lost time is 4 seconds per phase and a critical intersection v/c of 0.90 is desired.
PROBLEM 2. A lane group in an intersection approach with a pre-timed signal has a phase with display green of 48, with 4 seconds of yellow and all-red time and 2 seconds of lost time.
