  1. Adaptive Signal Control Initiatives and Validation Program Presenters Edward Fok, FHWA Resource Center Transportation Technology Specialist Dr. Douglas Gettman, Kimley-Horn & Associates Edward Smaglik, Northern Arizona University Assistant Professor of Civil Engineering

  2. Better, Faster, Smarter Shortening Project Delivery • Planning & Environmental Linkages • Legal Sufficiency Enhancements • Expanding Use of Programmatic Agreements • Use of In–Lieu Fee and Mitigation Banking • Clarifying the Scope of Preliminary Design • Flexibilities in ROW • Flexibilities in Utility Accommodation and Relocation • Enhanced Technical Assistance on Ongoing EISs Technology Innovation • Warm Mix Asphalt • Precast Bridge Elements • Geosynthetic Reinforced Soil • Safety Edge • Adaptive Signal Control Technology (ASCT)

  3. What have we learned… • Systems produce substantial benefits over coordinated TOD signal timing • Travel time, Delay, Emissions, Congestion, Safety • Most effective where: • demand conditions are Variable and unpredictable • Linear Arterials, limited success within tight grids • Under Saturated

  4. Barriers to Adoption of ASCT • Complexity • Cost • Uncertainty about Benefits

  5. Validation Program for ASCT • Generic Process and tools to measure any benefits from deployment of ASCT • Complementary to the Model System Engineering Document

  6. What is Validation? • Validation: Objectives are tested • Did it do what we want it to do? • Verification: Requirements are tested • Did we get what we asked for?

  7. Model Systems Engineering Document for ASCT Systems Basic Systems Engineering Deliverables • Concept of Operations • Requirements • High Level Design • Verification Plan • Validation Plan

  8. Model SE Document for ASCT Testing Testing Validation Needs Verification Requirements Design & Implementation

  9. ASCT Validation Process Testing Testing Validation Needs Verification Requirements Design & Implementation

  10. Our Goals for Today • Describe the challenges to validate ASCT • Describe the theoretical underpinning of our approach. • Describe the tools and the process developed to validate ASCT and the plans to test these techniques in Mesa, Arizona.
