17. April 29, 2010Operations Division17 Summary 99.7% Compliance with Tech Memo statewide Customers are positive, but satisfaction numbers went down and are nearing negative territory Many more grooved and wet-reflective markings being used, and unit costs for those are going down Increase in Preventative Maintenance hampering performance Marking durability is poor on chip seals and seal coats New mixes of hot mix asphalt causing some marking adhesion issues We need to find ways to improve perception and performance of our markings

18. April 29, 2010Operations Division18 OTST Emphasis Areas Draft Rumble Strips and StripE Tech Memo Just got approval of TEO Executive Committee Pavement Marking Tool Implementation continues Other research LRRB Best Practices for Local Roads project completed Pavement Markings under challenging conditions began Governors Initiative Safety Projects 2011 MnDOT Construction Spec Book rewrite Adoption of 2009 Federal MUTCD

19. Draft Rumble Tech Memo Combines two existing Tech Memos Rumble Strips on Shoulders of Rural Trunk Highways Edgeline Rumble StripEs Guidance for Rural Trunk Hwys. Requires the use of centerline rumble stripEs on all 2-way high-speed rural roadways on MnDOT trunkline Also requires shoulder rumble strips on all rural roadways with a paved shoulder 4 feet Edgeline rumble stripEs can be used in lieu of shoulder rumble strips in all cases, and centerline rumble stripEs on narrow surfaces MnDOT Bike and Ped section has been involved April 29, 2010Operations Division19

20. April 29, 2010Operations Division20 Pavement Marking Management Tool Statewide, GIS-based inventory of pavement markings that can be queried by MnDOT staff and the general public Contains installation and retroreflectivity info Working with the Center for Transportation Research and Education (CTRE) at Iowa State University

21. April 29, 2010Operations Division21 Tasks in PMMT Phase II Pilot Training in two Districts has occurred Historic installation and retroreflectivity data will be loaded Pavement marking data collection will be automated for both internal and contractor striping trucks Central Office and District staff will be trained on how to use the Tool This will be fully implemented by mid-2011

22. Emerging issues/activities Strongly considering requiring all striping contractors to have a data logging system (DLS) in their trucks as part of the Spec Book rewrite Some of our internal trucks already have these Contracting out more retroreflectivity readings More inspection of pavement markings More analysis of wet-reflective marking effectiveness Populate the Pavement Marking Management Tool Considering the use and implementation of wider longitudinal markings per 2009 Federal MUTCD trend April 29, 2010Operations Division22
