Work ZoneSafety and Mobility Transportation Management Plans Jason Gutting, P.E. Michigan Department of Transportation
TMP Process • Work Zone Safety and Mobility Policy • Developed by cross sectional team • Planners, Traffic and Safety, Development, Communications, etc. • Effective September 1, 2007 • Guidance Document • Applies to all MDOT work zones (construction, maintenance, permits/utilities) • Work Zone Safety and Mobility Manual • Roles, responsibilities, strategies, etc. • TMP process created while preparing the manual
TMP Contents • Transportation Management Plans (TMP) • Required on all projects • Temporary Traffic Control Plan (TTCP) • Transportation Operations Plan (TOP) • Public Information Plan (PIP) • Significant Project • TTCP, TOP and PIP Required • Non-Significant Project • TTCP Required • TOP and PIP Recommended
TMP Development • TMP development begins in the project planning and scoping phase • Involves planning and design staff • Incorporates big picture issues • Further details as project progresses • Allows more accurate programming and budgets • Maintaining traffic schemes (Temporary structure for maintaining traffic, crossovers, etc.) • Temporary ITS applications • Coordination with corridor and network projects
TMP Development • Project Design Phase • Details flushed out • Primary TMP development occurs during this stage in parallel with plan completion • Project delivery staff are engaged for better coordination and constructability reviews • Pay items are incorporated into the project plans and specifications • Special provisions are documented for project specific and/or unique issues
TMP Development • Statewide Peer Review Team (SPRT) • Mobility analysis and thresholds • Travel Time • Level of Service • Volume to Capacity Ratio • Project Rating system • Review Form • Red, Yellow, Green • Executive level engagement • Benefits • Check and balance for mobility issues • Feedback from other areas • Statewide Work Zone Administrator provides consistency • Staff have been very receptive of this review
TMP Implementation • Responsibility of project delivery staff • Strategy implementation • Changes, variations, etc. provided to development staff
TMP Implementation • Performance • Performance monitoring • Worksite trailers • Travel time • Queues • Cameras / Detectors • Crashes • How much did accidents decrease because of mitigation measures and comparable projects • Did accident severity decrease • Measurements versus expectations • How did actual measured delay compare with expected delay (travel time, queues) • Project documentation
TMP Lessons Learned • A TMP template was created to assist project development staff with TMP submittals • Uniformity • Critical Focus Area • TMP reviews are now conducted as needed versus at pre-determined dates • Less Time Crunch • Better Quality • Better Use of Staff Resources • Faster Response for Project Offices
TMP Lessons Learned • Public involvement in the TMP development is critical • Crash Analysis • Accurate Traffic Data
