9. Prime contractor: Virginia Tech Transportation Institute Budget: $300,000 Duration: 12 months Contract Start Date: February 9, 2009 L10 Feasibility of Using In-vehicle Video Data to Explore How to Modify Driver Behavior that Causes Non-Recurring Congestion This project will involve review of driver videos from past driving studies to determine the ability to extract useful information on behaviors and responses to factors that influence travel time reliability. Anticipated Products Report on the feasibility of using in-vehicle video data to help identify driver behavior modification strategies to improve travel time reliability

10. In-Vehicle Video Clip

11. Projects Nearing Completion Projects that will be completed this year

12. Prime contractor: Kimley-Horn & Associates Budget: $400,000 Duration: 18 months Expected Completion : August 2009 L01 Integrating Business Processes to Improve Reliability Development of case studies and summary information Business process and data flow diagrams capturing integrated procedures A guide on how to best integrate business processes related to operations Anticipated Products This project will identify and report on successful practices that integrate business processes to improve travel time reliability

13. I-80 Winter State Line Closures (NV/CA) Winter weather, elevation changes necessitate closure of CA/NV state line Limited (i.e., none) parking near state line for trucks not permitted to cross 5 year period – 23 closures, 31 truck prohibitions Typical winter day – 2500 trucks I-80 WB Why selected: Winter weather ops/management, multi- agency event management, freight, rural corridor

15. I-80 Agencies Involved NDOT District 2 Operations, Maintenance, PIO NDOT District 3 Operations/Operations Center Caltrans Nevada Highway Patrol Private Entities (Truck/Freight) Additional stakeholders – cities, counties, media

16. I-80 Process Types Pre-planning for winter operations/closures Process to establish closure and initiate notifications Internal agency processes/procedures for winter operations, closure operations Disseminating traveler information during hazardous winter conditions Planning and programming infrastructure to support corridor monitoring/info dissemination

17. Prime contractor: Cambridge Systematics, Inc. Budget: $1,750,000 Duration: 30 months Expected Completion: August 2009 L03 Analytic Procedures for Determining the Impacts of Reliability Mitigation Strategies Reliability vocabulary and definitions for application and communication Data and collection requirements, performance metrics, analysis methods Technical relationships between reliability improvement strategies, causes of non-recurring congestion and performance measures Anticipated Products This project will provide the means to predict what effect various improvement measures will have on travel time reliability performance

18. L03 Preliminary Findings Virtually all performance measures are derived from travel time distributions – reliability is a probabilistic phenomena At least six months of data are required to develop travel time distributions – a year is better Recommended reliability performance measures include Buffer Index, Failure/On-time Measures, Planning Time Index, Skew Statistic, Misery Index, Travel Time Index Travel time data traditionally comes from speed detectors on urban freeways- now the private sector is proving to be a valuable source of data on all key types of roads (e.g. signalized urban arterials)

19. Prime contractor: Parsons Brinckerhoff Budget: $1,000,000 Duration: 31.5 months Expected Completion: August 2009 L06 Institutional Architectures to Advance Operational Strategies Report providing guidance to transportation agencies on institutional architectures that will support operation programs that can improve travel time reliability Anticipated Products This project will examine the ways agencies should be organized to successfully execute operations programs to deliver travel time reliability by: conducting workshops to identify key issues examine and assess leading agency organizational structures examine organizational theory hold executive forums to determine the potential for widespread application

20. L06 Preliminary Findings Institutional issues account for the failure to capitalize on SO&M, not lack of concepts, technology or even money Only two states address SO&M as a stand-alone multi-year and annual budgeting process at the same level of formality as other core programs. A powerful approach for organizational self assessment and continuous improvement of operations is a Capability Maturity Model (CMM), similar to that used in the IT industry.

21. This framework would : consolidate the Reliability research findings to provide decision-makers and practitioners a guide to understand travel time reliability, incorporate reliability in project planning promote the merit of systems operations and management solutions to prevailing problems. develop and communicate the business case for travel time reliability L17 A Framework for Travel Time Reliability (New Project) A framework, possibly web-based product, that supports the planning, design and delivery of Reliability programs Anticipated Products

22. SHRP 2 Implementation Report to Congress in January 2009 recommended: AASHTO as principal implementation agent, in partnership with AASHTO, NHTSA and TRB Funding at $400M over 6 years Formal stakeholder advisory structure with detailed implementation plans Strategies to include- pilot testing of institutional approaches and technical products, lead users/demonstration projects, training and education programs, etc.

23. SHRP 2 and SSOM SHRP 2 will disseminate research results on a project by project basis- not solely at end of the program. A communication protocol between SHRP 2 and SSOM would have mutual benefits SHRP 2 implementation strategies- opportunities for SSOM members to conduct pilots, demos, be a lead state, etc.

24. Summary Program continues on schedule Project results becoming available now Dissemination of results will be a priority Encourage States to track and consider an active implementation role
