Rule on Work Rule on Work Zone Safety and Zone Safety and Mobility (23 CFR 630, Subpart J) Mobility (23 CFR 630, Subpart J)

  • Goals of the Rule

– Expand thinking beyond the actual WZ itself – Expand WZ management beyond just “traffic safety and traffic control” – Advocate innovative thinking in work zone planning, design and implementation

  • All current and future SHA projects should be in

compliance with the Rule

– Implementation Deadline was October 12, 2007

The Rule better reflects current needs for The Rule better reflects current needs for improved safety improved safety and and minimized traffic disruptions minimized traffic disruptions during the construction of highway projects during the construction of highway projects

Transportation Management Plans Transportation Management Plans (TMP) (TMP)

  • Which projects need a TMP?

– At SHA, all federal and non‐federal aid projects that are defined as “Significant Projects” – Non‐significant projects to the extent practical and feasible

  • What is a TMP?

– A TMP lays out a set of strategies and how these strategies will be implemented to manage work zone impacts

  • TMP strategies include:

– Temporary traffic control measures and devices (TCP) – Transportation operations (TO) strategies – Public information and outreach (PI&O) strategies

Significant Pr Significant Projects

  • jects
  • Why identify significant projects?

– Such that the appropriate resources (manpower and funding) can be allocated to projects with greater work zone impacts

  • When are significant projects identified?

– Project Scoping

  • Is my project “significant”?

– The lead office, or their consultant, will determine if a project is significant

  • What resources does SHA have for identifying

significant projects?

– “Guidance on Identifying Significant Projects” – Flow Charts

slide-9
SLIDE 9

9 9

Significant Pr Significant Projects

  • jects
  • What does SHA take into consideration when

identifying significant projects?

– Location (Freeway/Expressway, NHS, Principle Arterial) – Magnitude and extent of work zone impacts

  • Mobility Impacts (delays exceeding allowable mobility

thresholds)

  • Safety Impacts (worker and traveling public)

– Project characteristics

  • High level of public interest
  • Project duration/complexity
  • High accident intersections and segments
  • Unusual road work strategies
slide-10
SLIDE 10

10 10

Significant Pr Significant Projects

  • jects ‐

‐ Exceptions Exceptions

  • What if my project is considered significant

based on the “three day lane closure” rule*, but is not anticipated to have significant impacts?

– Submit a written request for an exception to the FHWA Maryland Division Office – SHA anticipates obtaining “blanket exceptions” for certain categories of projects

  • Maintenance projects, such as litter pickup, guardrail

repairs, and bridge cleaning * All Interstate system projects within the boundaries of a designated Transportation Management Area (TMA) that occupy a location for more than three days with either intermittent or continuous lane closures are considered significant projects.

Maintenance of Traffic Alternatives Maintenance of Traffic Alternatives Analysis (MOTAA) Analysis (MOTAA)

  • What is the purpose of the MOTAA?

– To compare work zone options, including staging/ phasing options as well as temporary traffic control

  • ptions, and to document maintenance of traffic

constraints for each option. – – Most important part: Most important part: Identify the impacts early enough in the project development process to make the changes necessary (right‐of‐way, bridge, environmental, etc.)

  • Which projects require a MOTAA?

– All significant projects

  • When should the MOTAA be conducted?

– Concept MOTAA during Project Planning (OPPE) – Detailed MOTAA during Preliminary Design

slide-12
SLIDE 12

12 12

Concept MOTAA Concept MOTAA

  • Occurs during project planning (construction

could be 10+ years away)

  • Investigate potential major maintenance of traffic

issues for each alternate retained for detailed study, such as:

– Constructability – Right‐of‐way, utility, and environmental impacts – Construction duration and cost – Mobility impacts (qualitative assessment of impacts on vehicular, pedestrian and bicycle traffic; access; emergency services; etc.)

  • Detailed traffic analysis is not required
slide-13
SLIDE 13

13 13

Detailed MOTAA Detailed MOTAA

  • Occurs during preliminary design, after the

preferred design alternate has been selected (ideally, prior to PI – 30%)

  • Investigate in more detail temporary traffic

control options for the selected design alternate

– Discuss work zone options with the Design Office and District Traffic prior to developing scope of work – Work Zone options may include:

– Full closure – Part‐width construction – Lane shifts or closures – Reversible lanes – Temporary structures – One‐lane, two‐way

  • perations

– Widening – Temporary crossover – Use of shoulder or median

slide-14
SLIDE 14

14 14

Detailed MOTAA Detailed MOTAA

  • Identify work zone constraints and report impacts
  • n any of the following:
  • MOTAA is more than just traffic analysis!

– Ability to comply with thresholds in Lane Closure Guidelines – Ability to maintain access (businesses, communities, etc.) – Ability to provide required ramp merge distances – Ramp capacity – Impacts on pedestrian and bicycle facilities – Impacts on emergency services – Public Safety – Ability to maintain existing drainage, utility and lighting systems – Right‐of‐way impacts – Environmental impacts – Bridge widths – Impacts to earthwork, pier clearances, retaining walls, profile differences, etc. – Constructability – Construction equipment access – Impacts on construction duration – Construction and MOT costs

slide-15
SLIDE 15

15 15

Detailed MOTAA Detailed MOTAA

  • Also consider at this time:

– Preliminary work zone impact management strategies – Preliminary cost estimates for strategy implementation (when available) – Information from other projects in the corridor to evaluate the combined or cumulative impact of the projects

slide-16
SLIDE 16

16 16

Documenting the MOTAA Documenting the MOTAA

  • “Guidance on Maintenance of Traffic Alternatives

Analysis” provides a suggested method of documentation

  • Office of Bridge Design has used a Kepner

– Tregoe Analysis

– Incorporates MOT into the decision on which project alternate moves forward for design

  • Bottom line – format is not important (for

Concept MOTAA or Detailed MOTAA) as long as all of the potential impacts have been considered

slide-17
SLIDE 17

17 17

After the MOTAA After the MOTAA

  • Re‐evaluate the significant project status

– Did the MOTAA identify an option that eliminates work zone impacts?

  • Consider a corridor/regional TMP

– If there are multiple or consecutive projects that are within the same general corridor, coordination amongst these projects will minimize the impacts

  • Review the budget

– Include funds in the CTP estimate for TMP development and implementation – Don’t forget to include funds for PI&O, Work Zone ITS, etc.

slide-18
SLIDE 18

Onto the TMP Onto the TMP

  • When should development of the TMP begin?

– All of the work done up to this point is a part of the TMP process – Ideally, first draft at PI – Realistically, first draft at Semi‐Final

  • Who’s responsible for developing the TMP?

– The TMP Coordinator, in consultation with the TMP Team

  • TMP Coordinator = Project Manager (or consultant)
  • TMP Team = appropriate representatives from SHA and
  • ther stakeholders
slide-19
SLIDE 19

TMP Development During Design TMP Development During Design

  • As design progresses, refine Traffic Control Plan

(TCP) and elements that were initially identified in the MOTAA

  • The TMP Team should work with technical

specialists to jointly identify/confirm:

– The work zone impacts that need to be addressed – The proposed work zone impact management strategies

  • Identify any TMP elements that:

– Require long lead times – Need to be established prior to the start of construction – Require improvements to be completed prior to the start

  • f construction (e.g., alternate route improvements)

More TMP F More TMP FAQS AQS

  • Contractors often change the TCP. How am I

supposed to know how the contractor will build the project?

  • Can a contractor make changes to the TMP?
  • Are we exposed to more legal liability by

providing a TMP at such a detailed level?

  • Doesn’t a comprehensive TMP add more to the

project cost?

  • How long should the TMP document be?
