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.

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.

• 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

  (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.
