We have developed an iPhone Application on Distracted Driving. According to the National Highway Traffic Safety Administration (NHTSA) driver distractions are the leading cause of most vehicle crashes and near-crashes. The App came about when we looked at a study released by the NHTSA and the Virginia Tech Transportation Institute (VTTI). The study discovered that 80% of crashes and 65% of near-crashes involve some form of driver distraction – and the distraction occurred within three seconds before the vehicle crash! For those in High Risk Security that number “three seconds” is familiar. It is the “Kill Zone”.
The Kill Zone Concept is used to train our troops in Iraq and Afghanistan to avoid a vehicle ambush. Our iPhone Application uses the same theory to explain and avoid the dangers of Distracted Driving.
The theory is simple; a Kill Zone is a time-distance relationship. How much time does the driver have and how close is the problem (distance)? The Kill Zone is directly related to the speed of the vehicle when the incident occurs.
An example of how Kill Zones relate to Distracted Driving look at the following scenario – You are 300 feet from a traffic light moving at 40 mph which is 60 feet per second. You get a text message; it takes 3 seconds to read the message – that means you drove 180 feet (3 seconds x 60 fps) without looking at the road.
You were 300 feet from the traffic light, but as you were reading the text message, you moved 180 feet. When you looked up from the text message, you are 120 feet (300 -180) from the traffic light that has now changed from yellow to red.
You are 120 feet in front of the red light and closing in at 60 fps. You are in the Kill Zone, a time distance relationship, the distance is 120 feet and some quick arithmetic tells you that you have two seconds to react. And you are driving deeper into the kill zone.
If you can get you foot on the brake in a half-second (that’s fast), you will travel 30 feet (half of 60 fps). So at the point of applying your brakes, you are 90 feet from the traffic light (the initial 120 feet minus the 30 feet it took to reach for the brake).
You will have to stop a car moving at 40 MPH (60 feet a sec) in 1.5 seconds. Life is going to get terribly exciting.
Our App uses case studies in the form of presentations, similar to the one above, and offers lessons learned. The objective is to keep you out of the kill zone.
