Process for Obtaining PennDOT Approval to Use Temporary Traffic Control Signals

Blanket Permits

The following information below will provide you with the requirements when considering a blanket permit for temporary traffic control signals.

What is a blanket permit?

  • For repeat users of portable traffic control signals, PennDOT's appropriate Engineering District Office may issue a blanket temporary traffic control signal permit covering multiple locations and dates of operation for up to a one-year period. This action will only be considered by PennDOT if that user has properly used portable traffic control signals in a safe and efficient manner on three or more past deployments without problems and in compliance with PennDOT requirements.
  • PennDOT's Bureau of Maintenance and Operations (BOMO) will be involved in the blanket process. Although permits are issued by the appropriate Engineering District Office, BOMO will participate in the evaluation process to determine whether a particular portable traffic control signal user can be issued their initial blanket permit in each Engineering District. BOMO will provide the overall blanket permit approval number, participate in any blanket permit revocation proceedings, and will keep track of users who have been issued blanket permits statewide.

What types of operations can be covered by a blanket permit?

  • Blanket permits can only be issued for short-term stationary operations (manual control, non-complex conditions) that satisfy the criteria and provisions of PATA 701 or PATA 702, except for emergency work as defined in Chapter 212. See Note 2 of each figure.
  • Blanket permits cannot be used for portable traffic control signal usage involving either long-term operations or short-term operations with complex conditions that are governed by PATA 703, 704, 705 or 706.

Who can apply for a blanket permit?

  • Any repeat user of portable traffic control signals who agrees to the responsibilities, terms, and conditions as outlined herein.
  • The blanket permit will be issued to up to two specific individuals (representing a company), and not to companies in general.

What are the roles and responsibilities of the blanket permittee?

  • Responsible for the proper installation, maintenance, and operation of the portable traffic control signal system as specified in PennDOT Publication 213 and the temporary traffic control signal permit.
  • Work closely with the work crew to provide safe and proper operations as specified in PennDOT Publication 213 and the temporary traffic control signal permit. Safety will be strictly enforced, and will not be compromised when using the devices.
  • Assist the work crew with PennDOT Publication 213 and temporary traffic control signal permit requirements for portable traffic control signal usage.
  • Provide technical and expert assistance on the use of the devices before, during, and after deployments to the contractors' personnel.
  • Take responsibility to ensure that the devices are working properly.
  • Approved products as specified in PennDOT Publication 35 (Bulletin 15) must be used.
  • Ensure the upkeep of the devices to PennDOT specifications and requirements maintained by the Bureau of Operations and Maintenance (BOMO).
  • Provide documentation, satisfactory to PennDOT, showing that the individual successfully completed a training course given by the manufacturer on the operation of the portable traffic control signal system that is being deployed under the blanket permit.
  • Ensure proper all-red clearance intervals and yellow change intervals are used as specified in PennDOT Publication 213 and the temporary traffic control signal permit.
  • Ensure appropriate green intervals are used based on traffic conditions. Ensure this is evaluated several times a day, and all changes should be documented.
  • Ensure that good records are kept of any changes during the operation of the devices.
  • Ensure that proper documentation is maintained on-site (including the temporary traffic control signal permit, PennDOT Publication 213, etc.).
  • Develop and document a contingency plan by the permitte prior to the deployment of the devices to establish procedures in the event of device failure or malfunction, or in the event of changing conditions or unforeseen circumstances.
  • Establish a designated on-site liaison from work crew. Topics to be covered with the on-site liaison include a contingency plan, basic programming and operation, take-down procedures, traffic monitoring responsibilities, driveway control, etc.
  • Provide the initial programming and the initial monitoring of the portable traffic control signals each day. All changes during the day should be made under the direction of the permittee and documented.
  • Be on-site at the start of signal usage each day. Provide emergency protocols and a contingency plan to address situations involving device malfunctions or changing conditions. Also, provide a direct number whereby the blanket permittee can be contacted at all times during signal usage.
  • Provide instructions to the work crew about proper removal procedures and how to place devices into a flash mode before going dark.
  • Visit the site in advance to ensure that proper usage can be achieved at the location of the upcoming deployment.
  • Continue to follow the appropriate processes outlined in PennDOT Publication 213 for obtaining PennDOT approval to use portable traffic control signals. The deadline for PennDOT District Office receipt of all required materials for the blanket permit request is at least 15 working days prior to the first desired usage date. Thereafter, required materials must be received by the appropriate District Office at least 3 full working days prior to each usage under an established blanket permit.
  • Coordinate yearly with PennDOT's Central Office and District Offices to ensure proper installations are occurring. Also, this will allow for a working relationship where the blanket permittee will be up-to-date with respect to the latest requirements and guidance documents.

What is the process/procedure to follow if an individual wants to be considered as a future blanket permittee?

  • Submit a written request to BOMO and the appropriate Engineering District(s) identifying the individuals seeking to be evaluated for future blanket permit consideration. Indicate the Engineering Districts where blanket permit consideration is being sought. Clearly indicate acceptance of the blanket permittee roles and responsibilities as outlined herein. Provide written documentation from the manufacturer of each portable traffic control signal system that will be deployed indicating that each individual seeking a blanket permit has successfully completed a training course given by the manufacturer on the operation of that signal system.
  • After receipt of the written request, PennDOT will contact the applicant to discuss the evaluation process and associated expectations. A series of successful trial deployments will need to be completed.
  • The appropriate processes outlined in PennDOT Publication 213 for obtaining PennDOT approval to use portable traffic control signals must be followed for the trial deployments. Failure to do so may result in rejection of the trial deployment.

How many successful trial deployments must be completed before obtaining a blanket permit?

  • The initial application will begin the evaluation of the trial deployments. Previous deployments will not be considered during the blanket permit evaluation.
  • A minimum of three proper deployments by the individual desiring to be a future blanket permittee, with at least one proper deployment in each Engineering District where a blanket permit is desired.
  • PennDOT will allow a maximum of two individuals from the same company to be evaluated on each trial deployment for the purposes of being considered as a future blanket permittee.
  • BHSTE will be actively involved in monitoring the trial deployments, and feedback received from District Office personnel, the work crew, the supplier/manufacturer, and others will be considered.

Upon successful completion of the trial deployments, what are the next steps?

  • PennDOT will document all comments and advise the applicant of successful completion of the trial deployments.
  • BOMO will work with District Office personnel to ensure that a blanket permit is issued to applicants that fulfill requirements

What about blanket permit revocation?

  • A blanket permit must be renewed each year.
  • A blanket permit can be revoked at any time for poor performance by the Engineering District. BOMO will be involved in any revocation proceedings.
  • If a blanket permit is revoked, that individual will not be allowed to submit for a blanket permit application for at least one year. Future submissions should follow the same procedures as a first-time applicant.

Guidelines for the Selection of Temporary Traffic Control Signals in Work Zones

Background

It is common for construction, maintenance, and utility operations to require the closing of a traffic lane during the course of their work. For the duration of the lane closure, traffic must be either diverted to another route via a detour, or merged into other lanes. When the lane closure is located on two-lane, two-way roadways and detour routes are not practical, then alternating traffic on the remaining open lane is the typical operational choice.

Purpose

The purpose of these guidelines and the accompanying selection chart are to provide guidance for selecting the appropriate temporary traffic signal control for short-term and long-term lane closures on two-lane, two-way roadways. These guidelines supplement PennDOT Publication 213 and assist in the determination of the minimum requirements for work zone traffic control for various traffic and roadway parameters. Definitions of terminology and distance charts for various parameters are also available in this document.

MUTCD Guidance on Temporary Traffic Control Signal

"Section 4D.20 Temporary Traffic Control Signals

Standard:
A temporary traffic control signal shall be defined as a traffic control signal that is installed for a limited time period. A portable traffic control signal shall be defined as a temporary traffic control signal that is designed so that it can be easily transported and reused at different locations.

Support:
A temporary traffic control signal is generally installed using methods that minimize the costs of installation, relocation, and/or removal. Typical temporary traffic control signals are for specific purposes, such as for one-lane, two-way facilities in temporary traffic control zones (see Chapter 4G), for a haul-road intersection, or for access to a site that will have a permanent access point developed at another location in the near future.

Standard:
Advance signing shall be used when employing a temporary traffic control signal.

A temporary traffic control signal shall:

  1. Meet the physical display and operational requirements of a conventional traffic control signal.
  2. Be removed when no longer needed.
  3. Be placed in the flashing mode when not being used if it will be operated in the steady mode within 5 working days; otherwise, it shall be removed.
  4. Be placed in the flashing mode during periods when it is not desirable to operate the signal, or the signal heads shall be covered, turned, or taken down to indicate that the signal is not in operation

Guidance:
A temporary traffic control signal should be used only if engineering judgment indicates that installing the signal will improve the overall safety and/or operation of the location. The use of temporary traffic control signals by a work crew on a regular basis in their work area should be subject to the approval of the jurisdiction having authority over the roadway

A temporary traffic control signal should not operate longer than 30 days unless associated with a longer-term temporary traffic control zone project

For use of temporary traffic control signals in temporary traffic control zones, reference should be made to Section 6F.80."

"Section 6F.80 Temporary Traffic Control Signals

Standard:
Temporary traffic control signals (see Section 4D.20) used to control road user movements through TTC zones and in other TTC situations shall meet the applicable provisions of Part 4.

Support:
Temporary traffic control signals are typically used in TTC zones such as temporary haul road crossings; temporary one-way operations along a one-lane, two-way highway; temporary one-way operations on bridges, reversible lanes, and intersections.

Standard:
One-lane, two-way vehicular traffic flow (see Chapter 4G) requires an all-red interval of sufficient duration for road users to clear the portion of the TTC zone controlled by the traffic control signals. Safeguards shall be incorporated to avoid the possibility of conflicting signal indications at each end of the TTC zone.

Guidance:
Where pedestrian traffic is detoured to a temporary traffic control signal, engineering judgment should be used to determine if pedestrian signals or accessible pedestrian signals (see Section 4E.06) are needed for crossing along an alternate route.

When temporary traffic control signals are used, conflict monitors typical of traditional traffic control signal operations should be used.

Option:
Temporary traffic control signals may be portable or temporarily mounted on fixed supports.

Standard:The supports for temporary traffic control signals shall not encroach into the minimum required width of a "pedestrian access route" of 1200 mm (48 in) or an "alternate circulation path" of 900 mm (36 in).

Guidance:
Temporary traffic control signals should only be used in situations where temporary traffic control signals are preferable to other means of traffic control, such as changing the work staging or work zone size to eliminate one-way vehicular traffic movements, using flaggers to control one-way or crossing movements, using STOP or YIELD signs, and using warning devices alone.

Support:
Factors related to the design and application of temporary traffic control signals include the following:

  1. Safety and road user needs;
  2. Work staging and operations;
  3. The feasibility of using other TTC strategies (for example, flaggers, providing space for two lanes, or detouring road users, including bicyclists and pedestrians);
  4. Sight distance restrictions;
  5. Human factors considerations (for example, lack of driver familiarity with temporary traffic control signals);
  6. Road-user volumes including roadway and intersection capacity;
  7. Affected side streets and driveways;
  8. Vehicle speeds;
  9. The placement of other TTC devices;
  10. Parking;
  11. Turning restrictions;
  12. Pedestrians;
  13. The nature of adjacent land uses (such as residential or commercial);
  14. Legal authority;
  15. Signal phasing and timing requirements;
  16. Full-time or part-time operation;
  17. Actuated, fixed-time, or manual operation;
  18. Power failures or other emergencies;
  19. Inspection and maintenance needs;
  20. Need for detailed placement, timing, and operation records; and
  21. Operation by contractors or by others.

Although temporary traffic control signals can be mounted on trailers or lightweight portable supports, fixed supports offer superior resistance to displacement or damage by severe weather, vehicle impact, and vandalism.

Guidance:
Other TTC devices should be used to supplement temporary traffic control signals, including warning and regulatory signs, pavement markings, and channelizing devices.

The design and placement of temporary traffic control signals should include interconnection to other traffic control signals along the subject roadway.

Temporary traffic control signals not in use should be covered or removed."

Verification of the agreement between the user and PennDOT will be evaluated prior to approval of a blanket permit request.

Short-Term Stationary Portable Traffic Control Signal Operation for Non-Complex Conditions - the “non-complex” application will be verified through a number of physical and operational requirements that the site must meet to be considered. These checks allow PennDOT to verify safe and efficient use if installed properly.

Short-Term Stationary Portable Traffic Control Signal Operation for Complex Conditions - the “complex” application would be any short-term portable signal installation that does not met the requirements for “non-complex” applications.

Short-Term Emergency Operation - An emergency application defined in PennDOT Publication 212.

Long-Term Portable Traffic Control Signal Operation - All physical and operational requirements should be part of the Traffic Control Plan.

Temporary Traffic Control Signal - as defined in the MUTCD is a traffic control signal that is installed for a limited time period. Temporary traffic control signals may be portable or temporarily mounted on fixed supports. Common types of temporary traffic control signals are signals mounted on span wire with temporary supports and trailer- mounted portable signals.

Work in Active Progress - Workers, other than flaggers, are present and are actively engaged in performing the necessary work.

Temporary Traffic Control Signals for Long-Term Stationary Operations

In the design phase of every project that will have temporary traffic signals, it is required that both installations on fixed supports and trailer-mounted portable traffic control signals always be considered before completing the design of the Traffic Control Plan (TCP). In some instances, trailer-mounted portable signals or installations on fixed supports can be used. On the other hand, in certain instances, installations on fixed supports may be preferable to trailer-mounted signals, or vice-versa, depending on the nature of the project, site conditions, traffic conditions, and other specific factors.

Before developing a TCP with temporary traffic signals, it is absolutely essential that the designer visit the proposed worksite beforehand. The site visit will enable the designer to evaluate various factors that will help in the determination of whether the TCP should permit both temporary signal design options, or one or the other. These factors include lateral clearance, trailer or pole placement, signal operation (phasing and timing), and others. Please also note that pedestal-mounted portable traffic control signals will not be considered for long-term stationary operations.

To establish the proper and acceptable temporary traffic control signal within a work zone, the following criteria should be considered:

Long-Term Stationary Operation Using Trailer-Mounted Portable Traffic Control Signals:
  • Pros:
  • Systems can be deployed quickly.
  • Especially conducive to deployments for emergencies.
  • Systems can be easily set up and taken down each day, or for multiple construction phases.
  • Equipment can be reused on future projects.
  • Equipment capable of being leased.
  • Cost savings potential.
  • Capable of wireless radio or hardwire interconnect.
  • Commonly equipped with monitoring system for location, low battery status, and conflicts using website and/or cell phone paging.
  • Commonly equipped with batteries that are solar recharging.
  • Commonly equipped with solar panels, rechargeable batteries, and ability to run via commercial power.
  • Wireless remote commonly available.
  • Cons:
  • Arm length can sometimes affect signal head placement.
  • Arm length affects number of signal heads that can be placed overhead.
  • Trailer size and/or arm length in conjunction with physical features can sometimes limit adequate placement.
  • Manufacturers have different operating systems.
  • More susceptible to vandalism.
  • Less appropriate for long-duration jobs on multilane, high-speed roadways.
Long-Term Stationary Operation Using Temporary Traffic Control Signals on Fixed Supports:
  • Pros:
  • Desirable signal head placement can be achieved.
  • More than two overhead signals can be erected.
  • Less susceptible to vandalism.
  • Pole placement sometimes may be easier to accommodate than trailers due to physical features.
  • Fixed supports may be more desirable for long duration deployments.
  • More appropriate for multilane approaches.
  • Employs common traffic signal control equipment and operational features.
  • Cons:
  • Inability to set up and take down each day.
  • Less appealing for short-duration jobs or jobs with short-duration, multiple set-ups.
  • Equipment and material availability is sometimes an issue.
  • Less cost savings potential.

If the designer determines that only one temporary signal design option is justified for a particular project, then the TCP shall be prepared accordingly, and written documentation shall be maintained in the project file outlining the reasons for this determination. It would also be desirable to clearly indicate on the TCP that the other option will not be permitted for the project.

If the designer determines that trailer-mounted portable signals or installations on fixed supports would be acceptable, then the TCP should clearly show the exact design and operation of both alternatives so that additional plans from the contractor would not be necessary. The TCP should include the design of all anticipated needed features. For example, if platforms or other special features will be needed, their design and placement should be in the TCP. Engineering judgment should be used and documented to determine the safest and most efficient operation for the work zone.

Temporary Traffic Control Signals for Short-Term Stationary Operations

Before developing and/or determining your traffic control plan (TCP) using PennDOT Publication 213, it is absolutely essential that the user visit the proposed worksite beforehand. The site visit will enable the user to evaluate various factors that will help in the determination of whether the TCP should permit temporary signal (portable signal) options, or other traffic control methods such as flaggers. These factors include lateral clearance, trailer or pedestal placement, signal operation (phasing and timing), and others. Please also note that installations on fixed supports are not considered viable for short-term stationary operations because of the amount of time and materials needed for installation.

If the user determines that portable traffic control signals will be an option and would like to pursue that option, then a completed application shall be submitted to PennDOT’s appropriate Engineering District Office. If the Engineering District Office agrees with the proposed usage, they will issue a temporary traffic control signal permit.
