Study Notes
Driving Risk Factors
- Major factors include the driver, the vehicle, and the roadway/environment.
IPDE Process
- The four steps: Identify, Predict, Decide, Execute.
Smith System Rules
- Drive safely by aiming high in steering, keeping your eyes moving, grasping the big picture, ensuring visibility for others, and leaving an "out."
Zone Control System Structure
- Use the steps: see a zone change, check other zones, and create time and space with speed control, lane position, and communication.
Zones of Zone Control System
- Six key zones: front, left front, right front, left rear, right rear, and rear zone.
Open and Closed Zones
- "Open zone": space available for driving without restrictions.
- "Closed zone": restricted space affecting line of sight or intended path.
Visual Search Pattern
- Utilize a systematic approach to search for clues around your path, incorporating short glances instead of staring.
Knowledge and Experience
- Driving experience enhances memory and prediction accuracy, improving decision-making.
IPDE Decisions
- Three critical decisions involve changing speed, direction, and communication.
Lane Positions
- Three possible positions within a lane: centered, 3-6 inches from the left, and 3-6 inches from the right.
Hazard Management
- Minimize a hazard by increasing distance, separate hazards by adjusting speed, and compromise space by giving more to the greater hazard.
Avoiding Conflict
- Essential actions: control speed, steer appropriately, and communicate effectively.
Commentary Driving
- Involves articulating thoughts while driving, promoting awareness.
Selective IPDE Use
- Apply the IPDE process selectively when conditions change in zones.
Time Required for IPDE
- The process requires time to identify clues, predict actions, and recognize potential closed zones.
Target Area
- Defined as the section of the roadway containing the target within the intended path.
Target Area Range
- The distance from your vehicle to the target area.
Time Ranges
- 4-6 second range: distance traveled in the next 4-6 seconds.
- 12-15 second range: distance traveled in the next 12-15 seconds.
Visual Search Patterns
- An orderly search pattern is essential for consistently checking critical areas.
Field of Vision
- Refers to the observable area around a driver while looking straight ahead.
Central and Peripheral Vision
- Central vision: a focused view up to 10 degrees.
- Peripheral vision: the area visible to the sides, also known as side vision.
Aiming High in Steering
- Looking 12-15 seconds ahead into your target area while driving.
Scanning
- Involves quick, continual glances for brief focus during a visual search.
Ground Viewing
- Refers to making brief glances at the road directly ahead of the vehicle.
