Visual Fields, Vehicle balance, traction control and SEEiT

Intro video: Functions

  • Focus Vision -______to _____ degrees of useful information
  • basis for reading and identify distinct objects
  • used when:
  • Central Vision - _____ to _____ degrees of useful information
  • basis for judging depth and position
  • gives support to focus vision and helps in:
  • Peripheral Vision - ______to ______degrees of useful information
  • used to pick up lateral changes in ______and ______
  • gives initial warning of changing or closed space areas
  • peripheral vision is strongly affected by fatique, dugs/alcohol and speed.
  • Define Path of Travel -
  • combination of targeting area, line of sight, visual references and guided experiences
  • alternate paths of travel may be necessary
  • Define Line of Sight –
  • Your line of sight can be blocked by a curve, hill, building or a vehicle.
  • if your line of sight is blocked adjust your ______and lane position until the following are restored:
  • Speed and Vision
  • as speed increases, the amount of information needed to maintain

    • car position and detect movement increases

    1. central vision ______and ______
    2. peripheral vision ______
    3. the faster you go the more you need to increase peripheral vision in order to increase motion detection farther away and increase time for adequate response to changes
    4. increase your space or following interval-more space allows for more response time.
    1. Vehicle Balance
    2. refers to:
    3. the following can shift the vehicle’s weight:
    4. balance is affected by:

    b.

    1. Changing Vehicle Balance
    2. Define Roll- when the vehicles weight shifts from side to side
    3. caused by:

    a.

    b.

    c.

    1. Front to Rear (Pitch)
    2. caused by sudden steering, braking, or acceleration
    3. acceleration transfers weight to the rear
    4. releasing the brake pedal
    5. Rear to Front (Pitch)
    6. caused by sudden steering, braking, or acceleration
    7. applying the brakes
    8. brake while traveling in a straight line in evenly distribute the weight of the vehicle over all four wheels (ex. before a curve)
    9. Define Yaw-
    10. caused by:
    11. break application and steering combination
    1. Traction Control
    2. Causes of Traction Loss
    3. ______
    4. ______
    5. ______
    6. ______
    7. ______
    8. ______
    9. Space Management System
    10. SEEiT: Search, Evaluate, Execute in Time
    11. Search means: an organized pattern of focused eye movements scanning the path of travel
    12. purpose is to:
    13. when searching, remember to:
    14. maintain a visual lead
    15. keep the eyes moving
    16. observe the sight line and travel path
    17. Evaluate
    18. ______high risk situations
    19. hazards
    20. intersections
    21. changes in roadway conditions
    22. speed and lane changes
    23. make a ______
    24. to help prevent or control a high risk situation
    25. Execute in Time
    26. in response to:
