Roadcraft Chptr 3 - Info, Obs, Anticipation Flashcards
Most important sense for driving?
Vision
What is the model that explains how how brain processes information you receive through your senses while you drive?
- Input (ie see a vehicle eating to put out of junction)
- Decision making
- Output (you slow down incase driver doesn’t see you)
- Feedback
…. And so on
How does you brain build up a detailed mental map of your situation?
It Uses your observations along with information from your previous experiences and knowledge that are stored in your long term memory
How does your brain make decisions regarding a plan of action from your input? (What you see)
It compares this mental picture with other situations from your experiences and identifies what actions you took in the past which have been carried out safely in similar situations, it then chooses a plan of action for the current situation based on this using ‘judgement’
3 types of judgement?
Anticipating how events are likely to unfold
Assessing proposed plan for risk, noting hazards and grading them based on previous experience
Assessing for space, position, speed and gear
What are the main limitations to how much info we can process at one time?
Reaction time
Errors of perception
Attention span
Memory storage
What is reaction time?
The time between gathering new information about a hazard and responding to it
Equation for reaction time?
Decision time + response time
Decision time = time between sporting hazard and deciding what to do
Response time = the time it takes to start the physical response (ie brake!)
What are the 3 common errors of perception
Errors of judgement (ie sharpness of a bend)
Habit and expectancy (ie driving a road regularly can prevent you from spotting a hazard that you don’t expect)
Regression effects (ie if swap vehicles regularly you could revert back to previously learned routines - ie confusing the position of the controls)
How can you improve information processing?
Regularly practice techniques and manoeuvres so you can do them accurately and efficiently
Sharpen your observation and perception and develop your situational awareness
Use the ‘system’ whenever you drive so you make decisions methodically and quickly
Learn to hold important info until you need them by repeating them
Anticipation?
The ability to identify hazards at he earliest possible opportunity
What is a hazard
Anything that is an actual or potential danger.
3 types of hazard?
Physical features (junctions, bends, road surface)
The position or movements of other road users (drivers, cyclists, pedestrians)
Weather conditions (rain, ice, poor visibility)
What are the 3 stages of planning?
Anticipate hazards
Prioritise
Decide what to do
What is the purpose of a plan?
To put you:
In the correct position
At the correct speed
With the correct gear engaged
At the correct time
In order to negotiate hazards safely and efficiently
