1 Developing and Implementing Mobility Management in Oregon W.D. Baldwin OBDP/HDR TCM 2008 Orlando, Florida

2 Outline Program Background How this Applies to All Work Zones Technologies and Strategies Used in the Program

3 OTIA III Bridge Delivery Program Economic and Bridge Options Report Hundreds of aging bridges would limit freight mobility on state and local systems Outlined economic threats of inaction Weight limits on Oregon s older bridges would limit freight mobility Recommended corridor-based solution Repair/replace more than 300 state highway bridges $1.3 billion Major freight routes statewide

4 OTIA III Bridge Delivery Program Legislative directive sets stage for project delivery through outsourced model Freight mobility, job creation, and program expenditures are linked to economic recovery of the state Minimize Delays Minimize Impacts to Freight Movement

5 OTIA III Bridge Delivery Program Oregon lawmakers pass comprehensive, 10-year, transportation improvement bills Largest investment in state s highway infrastructure in 50 years 2003 OTIA III = $2.46 billion over 10 years $1.3 billion to fund OTIA III State Bridge Program $300 million to repair or replace 141 local bridges $361 million for maintenance and preservation of county roads and city streets $500 million for modernization

6 OTIA III Bridge Delivery Program

7 OTIA III Bridge Delivery Program Goal of Traffic Mobility Minimize disruptions to motorists, the freight industry and communities without compromising public or worker safety, or the quality of work being performed. Keep Traffic Moving During Construction

8 Common Work Zone Challenges Sources of Congestion (FHWA Travel Congestion and Reliability 2004) Work Zones 10% Special Events 5% Poor Signal Timing 5% Bottlenecks, 40% Bad Weather 15% Traffic Incidents 25%

9 Common Work Zone Challenges Major Delays or Restrictions Caused by Minor Events Downed Poles/Utility Work New or Improved Roadway Entrances Delivery of Supplies to a Jobsite Survey Crew Geotechnical Drilling

10 Oregon Mobility Management Interaction with other disciplines Roadway Bridge ROW Public Information Environmental Etc

11 Oregon Mobility Management Planning, Design, Construction

12 Oregon Mobility Management Planning Part of Brainstorming Process Identify Potential Staging Constraints Early for Budgeting Purposes Organizing Statewide Projects to Minimize Impacts Maintain North/South and East/West Corridors

13 Oregon Mobility Management Construction Stages for Corridors

14 Stage One

15 Stage Two

16 Stage Three

17 Stage Four

18 Stage Five

19 Changing Traffic Staging Problems with the Original Approach of Completing the Stages of Construction Sequentially Economic Stimulus would be in Limited Areas Distribution of Contractors and Resources Linking of Region Projects with OTIA III Projects Schedule of Addressing Environmental Impacts Revised Approach Allowed Stages to Overlap Through the Development and Use of Project Travel Delay and Freight Mobility Requirements

23 Oregon Mobility Management Design Restriction Agreements

24 Oregon Mobility Management Transportation Management Plan (TMP) formal report that documents the overall approach to maintaining mobility Traffic Control Plan (TCP) - staging plan showing traffic control measures Project Specifications hours of lane closures, minimum lane widths, etc. These documents must be synchronized!

25 Oregon Mobility Management TMP Explains why you see what you see in the plans & specs Plans TMP Specifications

26 Oregon Mobility Management Construction Carry out the Plans Monitor and Report Manual Automated Adjust for Unforeseen Bad Weather Staging Plan Cannot be Carried Out Additional Time
