Rule on Work Zone Safety and Zone Safety and Rule on Work 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 The Rule better reflects current needs for The Rule better reflects current needs for improved safety and and minimized traffic disruptions minimized traffic disruptions improved safety during the construction of highway projects during the construction of highway projects • All current and future SHA projects should be in compliance with the Rule – Implementation Deadline was October 12, 2007 3 3

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 5 5
TMP Process TMP Process • Planning, Preliminary Investigation and Design Step 1 – Create TMP Team Step 2 – Compile Project Material Step 3 – Maintenance of Traffic Red Flag Summary Step 4 – – Identify Significant Projects Step 4 Identify Significant Projects Step 5 – – Maintenance of Traffic Alternative Analysis Step 5 Maintenance of Traffic Alternative Analysis (MOTAA) (MOTAA) Step 6 – Determine TMP Needs Step 7 – Identify Stakeholders and Revise TMP Team Step 8 – – Preliminary Design (Draft TMP) Step 8 Preliminary Design (Draft TMP) Step 9 – Step 9 – Detailed Design (Semi ‐ Detailed Design (Semi ‐ final, Final TMP) final, Final TMP) 6 6
TMP Process (cont.) (cont.) TMP Process • Construction Step 10 – – Implement TMP Step 10 Implement TMP Step 11 – – Monitor TMP Step 11 Monitor TMP Step 12 – – Update/Revise TMP Step 12 Update/Revise TMP • Performance Assessment Step 13 ‐ Evaluation 7 7
Significant Projects ojects Significant Pr • 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 8 8
Significant Projects ojects Significant Pr • 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 9 9
Significant Projects ojects ‐ ‐ Exceptions Significant Pr 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. 10 10
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 options, 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 11 11
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 12 12
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 – One ‐ lane, two ‐ way operations – Part ‐ width construction – Widening – Lane shifts or closures – Temporary crossover – Reversible lanes – Use of shoulder or median – Temporary structures 13 13
Detailed MOTAA Detailed MOTAA • Identify work zone constraints and report impacts on any of the following: – Ability to comply with – Ability to maintain existing thresholds in Lane drainage, utility and lighting Closure Guidelines systems – Ability to maintain access – Right ‐ of ‐ way impacts (businesses, – Environmental impacts communities, etc.) – Bridge widths – Ability to provide – Impacts to earthwork, pier required ramp merge clearances, retaining walls, distances profile differences, etc. – Ramp capacity – Constructability – Impacts on pedestrian – Construction equipment and bicycle facilities access – Impacts on emergency – Impacts on construction services duration – Public Safety – Construction and MOT costs • MOTAA is more than just traffic analysis! 14 14
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 15 15
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 16 16
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. 17 17
