==Prevention & Precautions : **Collisions Due To Heavy Traffic** ==

**Brief Description of Driving Safety Hazard **
Drivers need to be conscious of other drivers, especially in heavy traffic. They must pay attention to the stop lights and estimate the timing of the lights as well as keeping their distance from other cars. This is to make drivers safe preventing them from getting stuck in an intersection.

**Statistics or News Articles Related to this Hazard**
According to a 2005 survey of 1,000 people ages 15 and 17, conducted by the Allstate Foundation
 * More than half (56 percent) of young drivers use cell phones while driving,
 *  69 percent said that they speed to keep up with traffic
 * 64 percent said they speed to go through a yellow light.
 * 47 percent said that passengers sometimes distract them.
 * Nearly half said they believed that most crashes involving teens result from drunk drivin g.

**How the Kinematics (principles of motion) Relate to This Hazard **
Suppose Amirah's mother was on her way to drop off Amirah on a normal rush hour morning. Amirah's school is located at 22nd and Arch st. The length of 22nd street is 120 meters. The speed limit is 25mph. The green traffic light is 30 seconds per green light.The yellow lights are timed to stay yellow for 1 second for every 10mph the speed limit is. What car does Amirah's mother have to be to wait another light?

**How this Hazard Can Be Avoided With a Better Knowledge of Kinematics**
120/4.9784 = 24.10412 This equation represents the number of cars that able to fit on 22nd street.

24/2=12 This equation represents the number of cars that can fit on 22nd street safely.
