The MQA Program
  • The program is relatively new, the first
    inspection was in 1999

The MQA Program
  • The program is relatively new, the first
    inspection was in 1999
  • Inspection of 3360 randomly selected 0.1 mile
    sample segments representing approx. 3 of the
    Highway system.

  • Inspection of 3360 randomly selected 0.1 mile
    sample segments representing approx. 3 of the
    Highway system
  • Highway Features are divided into 5 Maintenance
    Categories

  • Target values are set based on customer

  • Provide Maintenance employees with clear
    expectations regarding maintenance activities

Definition of Traffic Guidance
  • Traffic Guidance is all KDOT-maintained
    signs, pavement markings, pavement striping,
    longitudinal barriers, object markers, and
    other devices placed on, over, or adjacent
    to the highway system to regulate, warn, or
    guide traffic.

Traffic Guidance Rating Elements
  • Warning Regulatory Signs 9
  • All Other Signs Markers 7
  • Guardrail / Attenuators / Barriers 8
  • Pavement Markings Striping 8

10
Traffic Guidance Warning / Regulatory Signs
  • MR Criteria 100 of warning and
    regulatory signs are reflective, readable,
    free of graffiti, securely mounted at the
    proper height, plumb (no more than 3 inches
    in 4 feet of post length in any
    direction), and correct for the intended
    purpose. 4 inch x 6 inch wooden posts will
    have breakaway holes drilled. Manual p. 25

Traffic Guidance Warning / Regulatory Signs
  • Measurement (continued)
  • Sign heights are measured from the near
    edge of the edge line to the sign bottom.
    Inspect to see if all warning and
    regulatory signs are a minimum of 5 ft on
    rural roads, a minimum of 6 ft for
    non-interstate controlled access roads and
    interstate roads, and a minimum of 7 ft
    for urban roads where parking and/or
    pedestrian movement is likely. Overhead
    signs should be mounted so that height
    from the sign bottom to the highest point
    on the roadway is a minimum of 17 feet.

13
Sign Height
Minimum of 5 ft (6 ft in new Sign Manual) on
rural roads, 6 ft on non-interstate
controlled access roads and interstate
roads, and 7 ft on urban roads where
parking and/or pedestrian movement is
likely.

Traffic Guidance All Other Signs (Guide
Signs Delineators)
  • Definition
  • Guide signs display directions, distances,
    route numbers, recreational areas, and
    geographic or cultural information.
  • Delineators are retroreflective devices
    mounted on posts, guardrails, or barriers
    at the roadside, in series, to indicate
    the roadway alignment.

24
Traffic Guidance All Other Signs (Guide
Signs and Delineators)
  • MR Criteria (Guide Signs) The sample passes
    if the sample meets all the following MR
    criteria
  • 90 of guide signs are reflective,
    readable, free of graffiti, securely mounted
    at the proper height, plumb (no more than
    3 inches in 4 feet of post length in
    any direction), and correct for the
    intended purpose. 4 inch x 6 inch wooden
    posts will have breakaway holes drilled.

25
Traffic Guidance All Other Signs (Guide
Signs and Delineators)
  • MR Criteria (Delineators) The sample
    passes if the sample meets all the
    following MR criteria
  • 75 of all delineators are reflective,
    mounted to the proper height, plumb (no
    more than 3 inches in 4 feet of post
    length in any direction), undamaged, and
    correct for the intended purpose.

26
Traffic Guidance All Other Signs
  • Measurement (Heights for Guide Signs)
  • Sign heights are measured from the near
    edge of the edge line or curb top to the
    sign bottom.

Traffic Guidance All Other Signs
  • Measurement (Flexible Delineator Height)
  • Flexible, plastic delineators cannot meet
    this
  • 48 3 height requirement if the base
    is properly driven into the ground. For
    flexible, plastic delineators, inspect to
    ensure the delineators are reflective,
    plumb, correct for the intended purpose,
    and that the base is properly driven into
    the ground.

Traffic Guidance Guardrail / Attenuators /
Barriers
  • Definition
  • Guardrails are longitudinal barriers
    constructed of continuous steel beams that
    provide for redirection of errant vehicles.
  • Cable guardrail are typically 2 or 3-strand
    cable systems that provide for redirection
    of errant vehicles.

38
Traffic Guidance Guardrail / Attenuators /
Barriers
  • Definition
  • Impact attenuators are devices designed to absorb
    energy when they are struck by an errant vehicle.
    Impact attenuators can be found near objects
    such as ends of concrete barriers, bridge piers
    or abutments, bridge rail ends, and overhead sign
    supports.
  • Concrete barriers are concrete devices
    designed to prevent vehicular penetration
    from the travelway to areas behind the
    concrete barrier.

39
Traffic Guidance Guardrail / Attenuators /
Barriers
  • MR Criteria The sample passes if the
    sample meets all the following MR criteria
  • 95 of continuous steel beam guardrails
    are free of dents, rust, or missing /
    damaged parts that degrade its intended
    purpose. Height- to- center bolt is 21
    inches 3 inches.
  • 95 of all cable guardrails are taut, free
    of protruding parts, and properly secured.
    Manual p. 27

  • MR Criteria The sample passes if the
    sample meets all the following MR criteria
    (Continued)
  • 100 of attenuators are functioning as
    intended.
  • 100 of all concrete barriers are
    properly aligned and free of
    structural distress.

Traffic Guidance Pavement Markings
Striping
  • Definition
  • Pavement striping consists of center lines,
    lane lines, no passing zone stripes, edge
    line stripes, channelizing lines, etc.
  • Pavement markings consist of diagonals in
    medians, gore markings at interchanges,
    turning lane and pavement arrow markings,
    word and symbol markings, special markings
    (e.g., crosswalk lines, railroad crossing,
    school zone, etc.) and raised / recessed
    pavement markers.

59
Traffic Guidance Pavement Markings
Striping
  • Definition
  • Pavement markers (raised / recessed) are
    reflectorized or non-reflectorized markers
    placed on the travelway to supplement
    pavement markings in an effort to provide
    additional delineation at night and in
    inclement weather conditions.

60
Traffic Guidance Pavement Markings
Striping
  • MR Criteria The sample passes if the
    sample meets all the following MR criteria
  • 95 of all pavement marking and striping
    is functioning as intended, not faded, and
    in neat lines.
  • Two or more consecutive raised / recessed
    pavement markers are not missing.

Applying Results
The Maintenance Quality Assurance Program is a
management tool to help maintenance managers to
identify and prioritize maintenance needs. This
management tool will also assist maintenance
managers in prioritizing maintenance projects and
resources as part of an annual, quarterly, or
monthly planning process.
