General Background

• Reason
• to provide standards and guidelines for the
  design, installation, and operation of TCDs at
  grade crossings of highway traffic and light rail
  transit vehicles
• Light rail transit vehicles
• metropolitan
• light rail vehicles, streetcars, trolleys
• operations in mixed traffic, semi-exclusive
  rights of way, or exclusive rights of way

4
Changes in General

• Only transportation officials in jurisdictions
  with light rail transit will be affected
• Affected officials will need to pay particular
  attention to Section 10C.11, highway-rail advance
  warning signs, which requires advance warning
  signs in advance of most light rail grade
  crossings. Any W10-6 signs will have to be
  removed and replaced with W10-1, W10-2, W10-3 ,
  or W10-4

Highway-Rail Advance Warning Signs
6
New Standards

• STANDARD light-rail transit versus railroads -
  use part 8 (10A.01)
• same tracks
• adjacent tracks
• automatic gates, flashing-light signals, and
  blank-out sign use has 5 year compliance period
• Temporary traffic control zone operations
  (10A.05/8A.05)
• discusses vehicles stopping on railroad tracks
• standard shall not allow, unless a law
  enforcement officer or flagger is provided
• need to minimize possibility of stopping

7
New Standards (contd)

• STANDARD crossings shall be equipped with
  (10B.01)
• a combination of traffic gates and flashing light
  signals,
• or flashing-light signals only,
• or traffic control signals,
• unless an engineering study indicates that the
  use of STOP, YIELD, or advance warning signs
  alone would be adequate

8
New Standards (contd)

• STANDARD sign design and size shall conform to
  chapter 2A. (10C.01)
• STANDARD STOP and YIELD sign placement shall
  conform to section 2B.06 and 2B.10. STOP AHEAD
  or YIELD AHEAD shall be installed with section
  2C.26. (10C.03)
• GUIDANCE use of signs limited to where
  engineering study determines it is needed and
  feasible

9
New Standards (contd)

• STANDARD use of highway-rail advance warning
  signs (10C.11)
• universal acceptance
• removal of existing W10-6 series
• STANDARD text on signal phases for exclusive
  turn lanes parallel to tracks (10D.06)
• from option to standard
• separately-controlled, protected only mode turn
  movements toward the crossing
• display of a red indication during the approach

10
New Standards (contd)

• STANDARD use of a separate set of standard
  traffic control signal indications (10D.07)
• for controlling light rail transit movements
• need to separate from other traffic signal heads
  by at least 1m (3ft)
• avoid motorist confusion

11
New Guidance

• Light-rail transit-activated blank-out turn
  prohibition signs (10C.06)
• should be used at
• STOP sign controlled intersections adjacent to a
  highway-light rail transit crossing or
• signalized intersections with permissive turn
  movements

12
New Guidance (contd)

• Pedestrian and bicyclist crossings and sight
  distance (10D.08)
• use of flashing-light signals with a cross-buck
  sign
• engineering study determines sight distance is
  not sufficient to complete crossing or
• light-rail transit speeds exceed 60 km/h (35
  mph).

New Options

• Four-quadrant gate systems (10D.02)
• use is optional
• if used, requirements in 10D.02 shall be followed
  
• similar to part 8, sections 8D.01 through 8D.03.
  Also, see figure 8D-2
