The American Association of State Highway Transportation Officials (AASHTO), the Institute of Traffic Engineers (ITE), and ITS America (ITSA) working together through the Vehicle to Infrastructure Deployment Coalition (V2I DC) have challenged state and local public sector transportation infrastructure owners and operators (IOOs) to work together to achieve deployment of roadside Dedicated Short Range Communications (DSRC) 5.9 GHz broadcast radio infrastructure to broadcast signal phase and timing (SPaT) in real-time at signalized intersections on at least one road corridor or street network (approximately 20 signalized intersections) in each of the 50 states by January 2020. This is commonly called the SPaT Challenge. Click here to download webinar overall slide deck.
Participants will have an understanding of the SPaT Challenge and resources that have been developed and are available to support an agency interested in planning a deployment, as well as preliminary information to plan for costs, procurements, and selecting a corridor for SPaT broadcasts.
- Blaine Leonard
Blaine Leonard is employed by the Utah Department of Transportation (UDOT) in Salt Lake City, where he is the Technology & Innovation Engineer. In this role, he is responsible for traffic management technologies, and leads the planning for connected and automated vehicles, including anticipating the impacts of those technologies on the Department. He co-chairs the American Association of State Highway and Transportation Officials (AASHTO) Connected and Automated Vehicles Working Group and leads the SPaT Challenge Tactical Working Group within the Vehicle to Infrastructure Deployment Coalition (V2I DC). Prior to joining UDOT, Blaine spent 20 years in the consulting engineering business.
Mr. Leonard served as the President of the American Society of Civil Engineers in 2010. He is a licensed engineer in six western states and is the Vice Chair of the Utah Professional Engineers and Professional Land Surveyors Licensing Board.
- David Kelley
Mr. Kelley is the long time editor of the SAE J2735 DSRC Message Set standard; as well as several other SAE standards. He has been active in the development and deployment of ITS standards for many years, both as a volunteer and as a paid contractor to SAE, NTCIP, IEEE and several other standards organizations. He has chaired standards committees for SAE, RTCM, NAB, EIA, now creating over fifty published standards. When not developing ITS standards, he is very active in vehicle positioning technologies. He is a subject matter expert in precision GNSS positioning methods, where he holds several patents. He will be speaking today about the constructs found in the MAP/SPAT messages of DSRC.
- Chuck Felice
Chuck Felice is a Project Manager over software development projects and GIS projects at the Utah Department of Transportation’s (UDOT) Traffic Operations Center. He is also a member of the connected vehicles group at UDOT and has been working on the Multi-Modal Intelligent Signal System (MMITSS) project for the last 2 ½ years. Chuck has over 35 years of experience working in the software industry in both the private and public sectors. He also has worked in the civil engineering, aerial photography, and mapping industries.
- Greg Larson
