Start Date:

June 12, 2018 from 2:00 pm – 3:30 pm EDT


This webinar will present an overview of procurement process, validation/verification of SPaT deployments, and securing SPaT broadcast. This webinar will also discuss potential applications that DOTs could deploy and potential next steps.

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.
