Short-Term Non-Complex (Pedestal-Mounted)

  1. The use of pedestal-mounted portable traffic control signals in Pennsylvania for short-term stationaryoperations with non-complex conditions shall comply with provisions of this figure.
  2. This figure may be used if all of the following field conditions are satisfied:
    1. The operation is a stationary, short-term operation as defined in PennDOT Publication 212 and 213.
    2. The portable traffic control signals are used to control one-lane, two-way traffic, and no more thantwo approaches to the work zone will be controlled by the portable traffic control signals.
    3. There is no at-grade railroad crossing within the one-lane, two-way traffic section (between STOPHERE ON RED SIGNS) and within 300 feet of a portable traffic control signal.
    4. No roadway approach to the portable traffic control signal is on a downgrade of 5% or more, if theormal speed limit is greater than 35 miles per hour.
    5. There are no intersections or uncontrolled driveways within the one-lane, two-way traffic section
  3. For manual control, a single operator may be used if the operator is located within the activity areaand hasan unobstructed view of both traffic traveling through the one-lane section and traffic on the approach to each portable traffic control signal unit. Otherwise, a separate operator is required at each portable traffic control signal unit and communications must be maintained between operators.
  4. Electronically submit a completed Notice of Commencement form (TE-161) to the appropriate PennDOT District Traffic Engineer so that it is received at least 3 business hours before the desired beginning time of the portable traffic control signal usage, except for emergency work as defined in PennDOT Publication 212. The Traffic Engineer may authorize commencement of work immediately on a case-by-case basis and shall provide information regarding the temporary traffic control zone to the appropriate District or Regional Traffic Management Center.
  5. The design and application of the portable traffic control signals shall comply with the most current version of PennDOT Publications 149, 212, & 213.
  6. Signal supports should be a minimum of 2 feet off the edge of travel way. If this is not possible, the supports shall be adequately delineated by channelizing devices.
  7. The pedestal-mounted portable traffic control signals shall have two signal faces on each approach.
  8. The length of yell ow change intervals is normally in the range from about 3 seconds to 6 seconds. Use a 5-second yellow change interval, or an appropriate alternative value from PennDOT Publication 149 based on actual site conditions.
  9. An all-red clearance interval must be used in accordance with all-red clearance interval calculations unless otherwise indicated by PennDOT. If the distance between the opposing Stop Here On Red (R10-6) signs is greater than 1000 ft. then the District Traffic Unit must be contacted to provide guidance as to the apppropriate timing for all red clearance intervals when applicable.
  10. For fixed time and actuated operations, the minimum green interval provided for each approach shall be10 seconds, unless otherwise indicated by PennDOT. The length of green intervals should be such as to provide for safe and efficient traffic operations. For green intervals, monitor traffic operations as traffic volumes change throughout the period of portable traffic control signal usage and adjust green intervals to provide for safe and efficient traffic operations.
  11. When not in operation, signal heads shall be removed from the view of traffic or hooded with a material that covers the signal indications from the view of traffic. All inappropriate signs shall also be removed, covered, folded, or turned so that they are not readable by oncoming traffic when the portable traffic control signal is not in operation.
  12. Signal modules must be replaced in accordance with the manufacturers' recommendations, and a record of the change must be maintained by the user.
  13. PennDOT reserves the right to inspect each portable traffic control signal usage.
