  1. Managing Work Zone Safety and Mobility presented by Param Sankar Cambridge Systematics, Inc. Acknowledgments Federal Highway Administration (FHWA) American Association of State Highway and Transportation Officials (AASHTO)

  2. Presentation Outline • Key Issues • Traffic Control Transportation Management • FHWA’s Final Rule on Work Zone (WZ) Safety and Mobility • Systematically Addressing WZ Issues in Project Delivery • Resources and More Information • WZ Management Strategies

  3. Key Issues

  4. More Work Zones • Our highways are approaching “middle age” • More construction and repair is needed – MORE WORK ZONES About 20% of NHS is under construction during the peak summer road work season

  5. Congestion • Growing traffic volumes and congestion • Vehicle travel up, but very little growth in road miles 1980 to 2001 – VMT increased by 82%, while highway lane miles only increased 4.2%

  6. Work Zones Add to Congestion • Work Zones add to the congestion problem

  7. Safety • Work zone safety continues to be a concern • 2003 to 2005: Roughly 40,000 injuries and 1,000 fatalities in WZs every year

  8. Contractors Under Pressure • More work is done under traffic • Compressed contractor schedules, interrupted shifts, increasing night work • Worker safety • Quality of work

  9. Public Dissatisfaction • Travelers are not happy with work zones • Unexpected road conditions and inconsistency cause traveler frustration 2000 Traveler Survey - work zones received second lowest overall satisfaction level!

  10. Culture Change Traffic Control Transportation Management

  11. Traffic Control Transportation Management • Systematic approach to assess and manage WZ impacts – customer-focused approach • Expand thinking beyond the actual WZ itself • Corridor, network and regional issues – alternate routes, modes, adjacent corridors, truck traffic, incidents, etc. • Expand WZ management beyond “traffic safety and control” • Address mobility in addition to safety • Address current day issues of “operations and management” and “public information” • Advocate innovative thinking in WZ planning, design, and management • Think outside of the “traffic safety and control” box

  12. FHWA’s Rule on Work Zone Safety and Mobility

  13. FHWA’s Final Rule • Entitled “Work Zone Safety and Mobility” • Published September 9, 2004; • Compliance date – October 12, 2007 • Key aspects • Institutionalize WZ processes and procedures • Partnership and multi-disciplinary approach • Advance WZ considerations throughout project delivery • Traffic Control Plan (TCPs)Transportation Management Plans (TMPs) • Active monitoring and management of WZ performance

  14. Key Concepts/Provisions WZ Impacts WZ Impacts WZ induced deviation from the normal range of transportation system safety and mobility…… • Impacts may vary based on factors such as: • Road classification • Area type • Traffic characteristics • Travel characteristics • Type of work • Time of day • Project complexity • Impacts may extend beyond the WZ • Roadway • Other corridors • Intersections • Interchanges • Other modes • Network/region

  15. Key Concepts/Provisions TMP Transportation Management Plan (TMP) • Consists of strategies to manage WZ impacts of projects • Always has a Temporary Traffic Control (TTC) Plan • In addition, it may also have: • Transportation Operations (TO) component, and • Public Information (PI) component • Scope, content and degree of detail depends on State’s • WZ policy provisions, and • Understanding of expected WZ impacts of projects

  16. Key Concepts/Provisions Significant Projects Obviously, you can’t have TO and PI components for all projects – so, there had to be a way to stratify TMPs • What is a significant project? • Causes sustained WZ impacts, greater than what is considered “tolerable” based on State policy and(or) engineering judgment • Specifically, all Interstate projects in designated TMAs that last more than three days with continuous or intermittent lane closures • How are the TMP provisions stratified? • For significant projects, TMPs must consist of a TTC plan, and also address TO and PI components • For all other projects, TMPs to consist at least of a TTC plan

  17. Considering Work Zones In Project Delivery

  18. Project Delivery Cycle Policy & Standard Procedures Systems Planning (TIP/STIP) Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  19. Policy and Standard Procedures • Implement overall WZ safety and mobility policy • Facilitates systematic consideration and management of WZ impacts throughout project development and implementation • Sensitive to varying project characteristics and expected WZ impacts • Multi-disciplinary team approach • Standard processes / procedures to help apply the policy to projects Systems Planning (TIP/STIP) Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  20. Systems Planning (TIP/STIP) Systems Planning (TIP/STIP) • Get a “conceptual” understanding of expected WZ impacts of projects • Identify “significant projects” • Allocate budgets and program the right amount of $$ Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  21. Preliminary Eng. / Investigation (PE&I) Systems Planning (TIP/STIP) • Identify potential WZ impacts • Identify potential transportation management strategies • Identify other coordination issues • Prepare blueprint for designing the project and developing the appropriate TMP Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  22. Design, PS&E, and Contracting Systems Planning (TIP/STIP) • Assess / Analyze WZ impacts (progressively and comprehensively) • Address alternative design, construction, contracting, and management strategies in the assessment • Develop appropriate TMP • Include appropriate TMP items in PS&E Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  23. Construction Systems Planning (TIP/STIP) • Implement TMP • Monitor safety and mobility • Use field observations, crash data, and operational information to manage impacts • Consult with appropriate stakeholders • Conduct project reviews for gauging overall performance Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment

  24. Performance Assessment (Post-hoc) Systems Planning (TIP/STIP) • Analyze crash and operational data from multiple projects • Towards improving processes and procedures • Maintain data and information resources to support improvements • Conduct process reviews • WZ data analysis and/or project reviews • Improve WZ processes and procedures, data and information resources, and training programs Preliminary Engineering & Investigation (PE&I) Design, PS&E, and Contracting Construction Performance Assessment
