DECISION-MAKING/ RISK REDUCTION
Define each risk component & give 1 example
Driver: risks that are contributed by the driver. Using a cell phone
Vehicle: factors caused by the vehicle. Broken headlights, dirty windshield.
Roadway: risks caused by roadway or environment. Bright sun, snow and ice, construction.
Good seeing habits & ability to manage space are tools for low-risk driving. Three low-risk & low-stress driving tools are
IPDE
SMITH SYSTEM
ZONE CONTROL SYSTEM
STOP – THINK - GO
Stop: what is the decision you are about to make? Good decision or bad decision?
Think: Think about good decisions and bad decisions. Is this the best way to do something?
Go: Make an effort to do the right thing. Make good decisions. Choose the decision that will benefit you the most in the most positive way that it can without harming others.
Including Smith & Zone Control Systems with IPDE helps with low-risk driving behaviors.
IPDE Process:
IDENTIFY: Know when to look, where to look, how to look, & what to look for
VISUAL SEARCH PATTERN TO IDENTIFY (3pts)
Open and closed zones
SPECIFIC CLUES
OTHER USERS
Roadways features and conditions
Traffic controls
PREDICT: use knowledge, judgement & experience to identify (3pts)
Actions of others
Speed
Direction
control
Points of conflict
DECIDE: decide to use one of more actions to (3pts):
Change or maintain speed
Change direction
Communicate
EXECUTE: execute your decisions to
Control speed
steer
Communicate
Combine Actions
SMITHING SYSTEM: ORGANIZED SYSTEM TO HELP DRIVERS DEVELOP GOOD SEEING HABITS.
FIVE KEYS
Aim high in steering
Get big picture
Keep eyes moving
Leave yourself an " out"
Make sure they can see you
Following Distance
__3 second___ Following distance recommended.
Use a fixed checkpoint to determine the distance
SEE Process
S: search
E: evaluate
E: execute
Organized method for managing six zones of space surrounding a vehicle.
Driver can see & respond to changes in traffic environment so control can be achieved
Three steps
See zone changes
Check other zones
CREATE time and space BY GETTING BEST SPEED CONTROL, LANE POSITION, & COMMUNICATION.
6 Zones around the vehicle:
OPEN ZONE: space without restriction
LINE OF SIGHT: distance a driver can see ahead in direction
PATH OF TRAVEL: space your vehicle will occupy
CLOSED ZONE: space not open
Searching Range
Target area range:space from vehicle to targeted area
12-15 second range: space you will travel in next 12-15 second range
4-6 second range: space you will travel in the next 4-6 second range
How would IPDE, Smith System, and Zone Control be different in different driving environments?
Urban Highways : 1 block ahead, pedestrians, delivery vehicles, parallel parking, narrow conditions, one way roads, public transportation vehicle, line of sight obstructions
Rural Highways : curves, intersections, hills, slow moving vehicles, animals, narrow roads
Expressways : interchanges: cloverleaf, diamond, trumpet. Entrance ramp, acceleration/merging lane , deceleration lane
