I need answers with explanation please!!
A-1. An exclusive through lane discharges 10 vehicles in 20 seconds. In the same amount of time a mixed lef-and-through lane discharges 3 left turning vehicles and 4 through vehicles. The left-turn equivalent is: a. b. 2 c. 20 seconds d. 6.66 seconds e. 3.33 seconds A-2. Detectors, in actuated controller operations, measure time between vehicle actuations which is then compared to (circle one of the options below) to extend green time: a. Minimum...
A four-phase traffic signal is to be designed for a major intersection
A four-phase traffic signal is to be designed for a major intersection. The critical volume to saturation flow rates (v/s for each phase are given below a) If lost time per phase is 2 seconds, determine the cycle length such that the critical v/c ratio for the intersection is 0.92. The cycle length needs to be rounded up to the nearest multiple of 5 b) For this cycle length, find the effective green times for each phase (Use the HCM method described...

2. Determine the minimum cycle length for the intersection with the volumes shown on the table below. The intersection is designed to have the following three phases: Phase A for left-turn movements from the EB and WB approaches; Phase B for the through and right movements from the EB and WB approaches; Phase C serving all movements for the NB and SB approaches. EB approach WB approach N B approach SB approach LT RLT RL TRL TR 110 500 200...

Word Problem) Two two-way streets meet at an intersection controlled by a four-way traffic light. In the east and west directions, the lights cycle from green to yellow to red. The south-facing lights do the same thing, except that they are red when the east-west lights are green or yellow, and vice versa. However, the north-facing lights are augmented with a green left turn arrow. They cycle red-green arrow-yellow arrow-green-yellow-red. Consider the following additional problem specifications: When the green or...
Show me the whole solution thank you so much :)
1. In a particularly long traffic light on your morning commute is green 30% of the time that you approach it. Assume that each morning represents an independent trial. What is the probability that the first morning that the light is not green is the sixth morning that you approach it?

2. For an airplane during landing, an angle of approach is defined as the angle formed by the runway and the path of the aircraft as it approaches the runway. For a safe landing, pilots need to land the plane with an angle of approach between 2.7 and 4.0 degrees. Upon arrival at its destination, an airplane is at an elevation of 100 feet and...
