1. What is the purpose of the ring barrier diagram?

2. How is timing represented in a ring barrier diagram?

3. Why use a ring barrier diagram instead of a conflict matrix to describe the sequencing of phases?

4. What is the difference between a movement and a phase ?

Expert Solution

1. What is the purpose of the ring barrier diagram?
Ans- The purpose of the ring barrier diagram is to separate movements which are able to safely time simultaneously (ensures that movements do not conflict). time simultaneously (ensures that movements do not conflict). sequencing of the movements or phases.

2. How is timing represented in a ring barrier diagram?

Timing can be represented in the reliability (theory)-based design (RBD) by the duration of the phases along the x-axis of the diagram.

3. Why use a ring barrier diagram instead of a conflict matrix to describe the sequencing of phases?

The conflict matrix shows compatible and conflicting movements or phases, but not sequencing of the movements or phases. This is the role of the ring barrier diagram.

4. What is the difference between a movement and a phase ?

A phase is the timing unit which controls one or more movements. A movement is a collection of users with a common direction.

Design an automatic traffic light control signal for a road square using 1MHz internal oscillator of PIC16F887. Each traffic light must consist of three (Red, Yellow, Green) lights. Use proteus for implementation. Your code must use four light signals installed on each road connecting to square. in word program form.(text and diagram )

What is meant by a direct signal and an indirect signal. Below is the answer I provided. Can you confirm if this answer should be changed to an indirect signal. And if yes, can you provide an example for an direct signal? A direct signal is a macro indicator that signals directly what is being measured, An example of a direct signal is if a bank closes $8,300,000 loans in February and $8,500,00 loans in March. In February the average...

1. On one approach of an intersection with fixed time traffic signal, vehicles arrival rate is 600 vehicles per hour. The effective green time for this approach is 30 seconds, the saturation flow of this approach is 1800 vehicles per hour and the cycle time of the intersection is 80 seconds. a. Evaluate the performance of the signal design i.e. will all vehicles clear during the green time? b. Recommend the changes to the green time for this approach to...
