  9. SETTING THE STAGE 9

  10. The nature of DOT business approach is changing • Transitioning from capital capacity projects to operating and maintaining the current system • Focused on “multimodal context based” solutions • Targeted to address multiple performance aspects of an asset. • Carbon Pollution Reduction & Clean Energy Action – http://governor.wa.gov/office/execorders/documents/14-04.pdf • WSDOT Executive Order 1090.00, “ Moving Washington Forward: Practical Solutions” (August 20th, 2014): − Use of quantitative methods including the Highway Safety Manual (HSM) − “Substantive versus nominal safety improvements.” − Least cost planning − Practical design 10

  11. WSDOT Illumination Systems 2014 • Existing systems: 3,100 (400 installed since 2005) • Roadway light fixtures: 60,000 • Cobra Heads 48% • Sign Lights 2% • Pole Top 3% • Underdeck 14% • Wall Mount 2% • Shoe Box 4% • High Mast 3% • Tunnel 24% 100% Source: SiMMS & Roadside Features Inventory Program (RFIP) database 11

  12. WSDOT Illumination Systems Budget does not fund annualized life cycle cost $13.95 MIL/yr $3 MIL Budget 12

  13. OPTIMIZING ASSET PERFORMANCE – CHALLENGING ASSUMPTIONS 13

  14. Why do we have so much lighting? 1974 - 1995 26.8 BCR Federal Highway Administration (1996). The 1996 Annual Report on Highway Safety Improvement Programs. Publication No. FHWA-SA-96-040; referenced in http://onlinepubs.trb.org/onlinepubs/nchrp/docs/NCHRP05-19_LitReview.pdf 14

  15. Intended Outcomes Goal - Develop a risk-based approach that considers roadway lighting performance and risks to achieve and optimal level of lighting without significant impacts to crash and mobility strategic goals and objectives • Reduce Life Cycle Cost (Asset Performance) – Provide light only when needed (existing and future systems) – Then, Convert to high – efficiency LED technology • Sustainable and Clean Technology (Asset Impacts) • Recognize advancements in safety analysis 15

  18. Domestic & International Illumination Research Review Datasets • >300 papers & reports (1960’s – 2014) - Sample size: how many crashes were analyzed and what are the confidence • Rigor of research levels for the results? methods evaluated - What site characteristics were collected based on: and included in the analysis? Analysis method Experimental design – Is the method science-based and valid – Site selection: were the sites for crash analysis? similar in characteristics or different? What criteria were – Are the assumptions scientifically used? sound? – Which crashes were included in the analysis? – Did the method account for differences How were they identified? in roadway characteristics that we know have impact on crash performance? 18

  19. How do we define nighttime? 45% of Crashes during these crashes times are NOT typically previously corrected with lighting considered to have occurred at night Nighttime Nighttime definition excludes civil dusk and civil dawn Original graphic source: "Twilight subcategories" by TWCarlson - Own work.

  20. Domestic & International Illumination Research Review • Published research from 2010 – 2014 – In general terms only research conducted after 2010 included the consideration of other factors besides illumination that may have impacted the crash reduction performance. • Geometry / Channelization • Speed • Traffic Volume • Congestion • Pavement Markings • Access Density • Published research prior to 2010 – Before / After Crash analysis is suspect to “apples and oranges” type issues 20
