<strong>IPDE</strong> <strong>Process</strong><br />

&<br />

Smith System


<strong>IPDE</strong> <strong>Process</strong>:<br />

4 steps…<br />

• I = Identify<br />

• P = Predict<br />

• D = Decide<br />

• E = Execute


Identify<br />

• Accurate picture of the scene in order to<br />

identify any critical objects.<br />

• Vision<br />

• Space cushion – Space around your vehicle<br />

• Field of vision – everything you can see<br />

while looking straight ahead<br />

• Sight distance – distance you see ahead<br />

• Auditory<br />

• Honking horns, train horn, siren, squealing<br />

tires


Predict<br />

• Predict possible outcomes.<br />

• Traffic laws <strong>and</strong> controls, physical forces, <strong>and</strong><br />

reading other driver on the road.<br />

Important questions are:<br />

Which of these could cause a threat?<br />

Which ones are potential hazards?<br />

Which are real hazards?


Decide<br />

• Planning a course of action.<br />

• Escape path – where to go incase of<br />

an unexpected conflict.<br />

• Safe path of travel – path free of all<br />

hazards.<br />

• Minimize – putting more space<br />

between you <strong>and</strong> a potential hazard.<br />

• Separating – h<strong>and</strong>ling one hazard at a<br />

time.


Execute<br />

Taking action…<br />

A driver has three courses of<br />

action:<br />

1. Accelerate<br />

2. Brake<br />

3. Steer to left or right.


Smith System<br />

Five points:<br />

1. Aim High Steering<br />

2. Get the Big Picture<br />

3. Keep Your Eyes Moving<br />

4. Leave Yourself an Out<br />

5. Make Sure They See You


Aim High Steering<br />

• Keep 12 – 15 seconds of eye lead-time<br />

• Look ahead, far ahead.<br />

• Look far down the road, where the road<br />

disappears.<br />

• Know Field of vision.<br />

• Peripheral Vision – how far a person<br />

can see to the right <strong>and</strong> left while<br />

looking straight.<br />

• Central Vision – area in your central<br />

vision where you can see clearly while<br />

looking straight.


Get the Big Picture<br />

Be Aware of all objects &<br />

obstacles:<br />

• 1 - 2 city blocks ahead.<br />

• ½ mile on highways, expressways &<br />

country roads.<br />

• Sidewalk to Sidewalk.<br />

• All of the area around your vehicle.


Keep Your Eyes Moving<br />

• Check mirrors every 5 – 8 seconds.<br />

• Scan your eyes every 2 seconds.<br />

• Never stare at an object for more than 2<br />

seconds.<br />

• Eliminate Eye Holding Problems.<br />

• Adjust Speed: Speed up or slow down<br />

• Change Lanes.<br />

• Adjust Radio: Turn on music, turn up music,<br />

turn down music, <strong>and</strong> change station…<br />

• Roll down window, turn up air conditioner, <strong>and</strong><br />

turn off heater.<br />

• Sing or talk to yourself or others.<br />

• Pull over, take a break or get rest.


Leave Yourself an Out<br />

• Leave a 1 car-length space cushion at stop signs<br />

<strong>and</strong> intersections. (Stop so you can see their<br />

tires!)<br />

• Keep at least a 2 seconds following distance in<br />

front of your vehicle. (If possible 4 seconds).<br />

• Keep at least a 3-4 seconds following distance<br />

during adverse weather.<br />

• Eliminate Tailgaters:<br />

• Adjust Speed: Speed up or slow down.<br />

• Change Lanes.<br />

• Allow them to pass: Pull over to the side of the road or<br />

turn off on to anther road.<br />

• Signal a warning:<br />

• Turn on / Turn off Headlights.<br />

• Machine gun brake tap.


Make Sure They See You<br />

COMMUNICATION:<br />

• Make Eye Contact.<br />

• Honk Horn (Twice).<br />

• Turn on / Turn off Headlights.<br />

• Brake Tap.<br />

• Use turn signals.
