Your task in this assignment is to estimate how fast you would have to be driving and at what distances from the traffic light you get in trouble. It is clear that if you are very far, then you can always stop, and if you are very close, then you can always pass with the yellow. But there is an in-between region that is problematic.(adsbygoogle = window.adsbygoogle || []).push({});

First, you should recall why this happens. This is the part of an investigation where you identify the main problem and its general features. I suggest that you review your notes of chapter two when we talked about this problem and review the textbook.

Then, you should go into specifics. The answer to the problem depends on how long the yellow light stays on, the maximum forward and backward (breaking) accelerations of the car. In class we just made up some numbers to see how the problem worked, but you should try to get real numbers here. This is a case-study.

So, you should get real data on how long the yellow light lasts on different traffic lights and what the maximum acceleration of cars is (some data on real power output and car masses may help). The size of the intersection also matters, since if you are trying to stop, then you should stop before the intersection and if you are trying to pass, then you must clear the whole intersection. You may also want to consider the driver's reaction time.

Finally, you should worry about the maximum speed of the car. If, in order to pass the intersection, the car must "floor the accelerator", then you should take into account that after reaching its maximum velocity it just moves with constant velocity.

Your final result should be some data specifying:

1. The velocity where you start getting into trouble,

2. The range of distances where you run into trouble,

3. List those results for several types of traffic lights (depending on how long its yellow light lasts), and several types of cars, using standard size of intersection and average reaction time.

yah this is my assignment and i ve been trying for about 2 weeks now and dont understand this
