SPaT Challenge What is the Challenge? To challenge state and local public sector transportation IOOs to cooperate together to achieve deployment of DSRC infrastructure with SPaT broadcasts in at least one corridor or network (approximately 20 signalized intersections) in each state by January 2020 7

SPaT Challenge What is SPaT? A Signal Phase and Timing (SPaT) message defines the current intersection signal light phases Current state of all lanes at intersection are provided, as well as any active pre-emption or priority. SPaT message defined by SAE J2735 (a subject of a subsequent webinar) 8

SPaT Challenge Why do this Challenge? To provide IOOs with an entry into DSRC-based V2I deployment and gain valuable procurement, licensing, installation, and operation experience, which in turn will:  Lay ground work for more advanced V2I deployments  Show a commitment to OEMs and applications developers  Analogous to early fiber deployments – most benefits came later 9

SPaT Challenge What are the benefits? • Be more prepared for DSRC-equipped vehicles and on-board V2I applications • Useful as testing site for future applications • Supports deployment of V2I applications that build on SPaT at intersections:  Smart Transit Signal Priority  Red Light Violation Warning  Intelligent Signal Systems  Eco-Driver 10

SPaT Challenge What is the long-term goal? • Widespread deployment of V2I applications at intersections will lead to:  Improved safety for drivers and pedestrians  Improved mobility for traveling public, transit, freight, snow plows, and other fleet vehicles • High penetration rates in vehicles  Agency vehicles and OEM-produced vehicles able to utilize and benefit from SPaT broadcasts • We have to start small . . . And scale up! 11

Systems Engineering Approach to the SPaT Challenge Ray Starr, Minnesota DOT

Why a Systems Engineering Approach? • Federal funding requires it • System that meets user needs • Needs are not missed • Common understanding of intent • Basis for testing • Stakeholder roles • Especially valuable for implementing non- routine systems 16
