SPaT Challenge Webinar #2: SPaT Challenge Design Considerations (part 1)


This webinar is part 2 of SPaT Challenge webinar series. Click here to view part 1 recording and register for part 3part 4part 5, and a technical demo of map message creator tool.  This webinar will present on minimum content for SPaT broadcasts to be verified/validated and signal controller interface/creation of SPaT messages. The webinar will also present examples of designs for assembling SPaT messages.

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.



Learning Objectives:

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.
