** Brief Description of Driving Safety Hazard: **

When doing a stop light violation not only do you jeopardize your life, but pedestrians around you. Small children and/or adults crossing at the intersections could be walking, or cars that have the green like could be passing through. It is important to follow this rule of the road to make sure everyone gets to where the have desired safely and soundly. In this scenario I will demonstrate three different cases of how you can judge when to slow down if you are going below, above, or at the speed limit given. The time of day is 12am on a Tuesday night in the urban city of Philadelphia. There are approx. 4 cars on the road, all in the left turning lane. She has the road clear to herself.

= The Problem: =



= = Jessica was on her way to the hospital because she received news that her sister was having her baby, and she wanted her to be there. Before leaving her home, which is exactly 500m (approx 1/8 of mile) from the hospital, Jessica thought about would driving over the speed limit get her there faster. Driving the legal limit get her there quicker, or going beneath the speed limit, hoping to catch more green lights get her there in time for delivery.

//** Quick Facts: **// - It takes one block to get to the hospital - The speed limit 35mph - The distance from the top of the street is 500m (approx. 1/8 of a mile) - Red light: 30 seconds & Green light: 30 seconds Yellow light: 4 seconds

//** Questions: **// -- If Jessica is going 20.1164m with a constant velocity of 8.7m/s every 6 seconds, what is the necessary acceleration for the car to stop in time not to run a red light? - - At 15.64m with a constant velocity of 7.98m/s, every 5 seconds? - - At 11.176 m with a constant velocity of 6.82m/s, every 3 seconds?

//** Calculations: **//



The distance equation is telling the observer how many meters Jessica will be at when green light is turning yellow, at the acceleration she is going at constantly. The velocity equations is telling us the total meters being traveled in total, and the acceleration is telling us how many seconds Jessica needs to slow down each meter.

The distance equation is telling the observer how many meters Jessica will be at when green light is turning yellow, at the acceleration she is going at constantly. The velocity equations is telling us the total meters being traveled in total, and the acceleration is telling us how many seconds Jessica needs to slow down each meter.

The distance equation is telling the observer how many meters Jessica will be at when green light is turning yellow, at the acceleration she is going at constantly. The velocity equations is telling us the total meters being traveled in total, and the acceleration is telling us how many seconds Jessica needs to slow down each meter. =**Using Kinemetics:**= Using the formulas **velocity (final) = acceleration x time + velocity (initial)** and **displacement = ½ × acceleration × time² + initial velocity × time,** it is and will become easier for drivers to control their acceleration. After putting in their data the answer given to them will show them the change that needs to be made in their driving speed each second they are getting nearer to the intersection before the lights turns red and while it is turning yellow.

=Conclusion: = Drivers can use kinematics to help with stop light violations with the acceleration equation. By slowing down each time in a due amount of seconds distinctive to their speed and distance from the intersection, they will be able to stop in time to not run a red light. Not slowing down in time for yellow lights and running lights can cause many fatal accidents. By using kinematics, drivers will be able to avoid accidents. Also by understanding them, it will be easier to judge when you need to slow your car down or come to an complete stop. It is important to remember that cars work off of strictly how you operate them and the laws of motion
