 Collision Pedestrian Vs. The Speeding Car

The importance of this project to educate the public about collisions that could be avoided by paying attention to the pedestrian sign that many streets in Philadelphia are starting to make on every corner. They are about 15 seconds, 24 seconds, and some are longer for when a. It depends on how big the intersection street is for when the pedestrian and car.

A pedestrian is walking across the 22nd and Arch intersection going 1.84 mph on a yellow light which lasts 3.5 seconds. Meanwhile a reckless driver of a new 2010 Porsche who was going 45 mph in a 30 mph zone, struck the pedestrian who had 3.5 seconds to get across the street. He, the driver, did not put on his brakes quick enough, to allow any escape from the collision. At what distance did the pedestrian and the car collide. How many seconds was it?

Pedestrian Speed: 1.84 mph (in meters 0.8320) Speed Limit - 30 mph Cars Acceleration - 45 mph Distance From - 22nd and Market to 22nd and Arch. .1 miles.
 * Key Notes**:The acceleration for the car is 1.86 miles per hour since the pedestrian is walking at a constant velocity each time. Since the velocity of the pedestrian is going at a constant pace the acceleration will be the same.
 * Answer:** The pedestrian and the car will collide after 8 seconds.

72420.48/3600=20.1168 He was going **20.11(velocity)** meters per second. 20.1168/5=**4.0233** meters per second**(acceleration)** 160.93/20.11=8.002 seconds 0.1miles*1609.344(the number of meters that equal one mile)= 160.93meters
 * Mathematical Reasoning:** 45*1069.344=72420.48

 * Statistics:**


 * Conclusion:** It is more necessary if the pedestrian walks during the indicated green light instead of yellow. For the simple fact they have the right to get across 3.5 seconds in a 30 mph zone. For an instant if the driver of a car was going over the speed limit and was talking on the phone when he believe that he had the righ to the light.Do NOT go over the speed limit. Pedestrians should not attempt to cross the street on a yellow light, but rather cross on a green light. when you are signal to go you should go and not go after-wards It will cause collision and you could die
