Transportation Management Plans Transportation Management Plans (TMP) (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
– A TMP lays out a set of strategies and how these strategies will be implemented to manage work zone impacts
– Temporary traffic control measures and devices (TCP) – Transportation operations (TO) strategies – Public information and outreach (PI&O) strategies

Step 1 – Create TMP Team Step 2 – Compile Project Material Step 3 – Maintenance of Traffic Red Flag Summary Step 4 Step 4 – – Identify Significant Projects Identify Significant Projects Step 5 Step 5 – – Maintenance of Traffic Alternative Analysis Maintenance of Traffic Alternative Analysis (MOTAA) (MOTAA) Step 6 – Determine TMP Needs Step 7 – Identify Stakeholders and Revise TMP Team Step 8 Step 8 – – Preliminary Design (Draft TMP) Preliminary Design (Draft TMP) Step 9 Step 9 – – Detailed Design (Semi Detailed Design (Semi‐ ‐final, Final TMP) final, Final TMP)

– Such that the appropriate resources (manpower and funding) can be allocated to projects with greater work zone impacts
– Project Scoping
– The lead office, or their consultant, will determine if a project is significant
significant projects?
– “Guidance on Identifying Significant Projects” – Flow Charts

identifying significant projects?
– Location (Freeway/Expressway, NHS, Principle Arterial) – Magnitude and extent of work zone impacts
thresholds)
– Project characteristics
10 10
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
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)
– To compare work zone options, including staging/ phasing options as well as temporary traffic control
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.)
– All significant projects
– Concept MOTAA during Project Planning (OPPE) – Detailed MOTAA during Preliminary Design

could be 10+ years away)
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.)
13 13
preferred design alternate has been selected (ideally, prior to PI – 30%)
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
– Widening – Temporary crossover – Use of shoulder or median
14 14
– 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
15 15
– 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
16 16
Analysis” provides a suggested method of documentation
– Tregoe Analysis
– Incorporates MOT into the decision on which project alternate moves forward for design
Concept MOTAA or Detailed MOTAA) as long as all of the potential impacts have been considered
17 17
– Did the MOTAA identify an option that eliminates work zone impacts?
– If there are multiple or consecutive projects that are within the same general corridor, coordination amongst these projects will minimize the impacts
– Include funds in the CTP estimate for TMP development and implementation – Don’t forget to include funds for PI&O, Work Zone ITS, etc.
18 18
– 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
– The TMP Coordinator, in consultation with the TMP Team

(TCP) and elements that were initially identified in the MOTAA
specialists to jointly identify/confirm:
– The work zone impacts that need to be addressed – The proposed work zone impact management strategies
– Require long lead times – Need to be established prior to the start of construction – Require improvements to be completed prior to the start

Fine Tuning Fine Tuning Temporary Traffic Temporary Traffic Control (TTC) Strategies Control (TTC) Strategies
– Phasing/staging, full closure, lane shifts and closures, crossovers, detours, etc.
– Night work, weekend work, special events, seasonal traffic, environmental time restrictions, etc.
– Signing, striping, signals

22 22
Selecting Public Selecting Public Information and Outreach Information and Outreach (PI&O) Strategies (PI&O) Strategies
– Newsletters, brochures, etc. – Press releases – Mass Media (earned and/or paid) – Project website (project information, construction progress, traffic cameras) – Public meetings, workshops, community events
– Radio traffic news – Changeable message signs – Email alerts – Highway Advisory Radio
23 23
– Project summary, goals and objectives – Anticipated work zone impacts – Stakeholders and others impacted by the project – SHA and other projects in the vicinity that may require coordination – Narrative of the recommended construction phasing/staging strategies – Traffic analysis and results – Proposed work zone impact management strategies (TO and PI&O) and associated costs – Preliminary TCP showing construction phasing/staging
– Refer to SHA’s “Transportation Management Plans: Guidelines for Development, Implementation and Assessment”
24 24
– Address any comments from previous submissions – Develop plans in more detail to show temporary signing, striping, signals, etc.
– Address any comments on draft TMP – Modify and fine tune TO and PI&O strategies TMP as project evolves
estimate
25 25
– SHA and the Contractor must designate a trained person at the project level to implement the TMP and
Traffic Manager
– Efficiently and appropriately implementing the TMP – Reviewing traffic operations throughout the project limits, including the condition of all traffic control devices, on a regular basis.
26 26
– Assure that media tools (CMS, HAR, etc.) provide accurate and timely information – Ensure contractor compliance with lane closure pickup times.
– Implement monitoring requirements as specified in contract documents (monitoring queue lengths, documentation requirements, etc.) – Discuss TMP implementation and monitoring at monthly partnering meetings (as needed) – Determine if additional TMP elements are needed or if particular elements need refinement
27 27
responsible for maintaining current documentation regarding:
– Deficiencies identified during TMP implementation – How and when these deficiencies were corrected
changes to the District for review and approval
– Changes to work activities that alter traffic control requirements – Changes to any work zone impact strategies
