SPaT Challenge Overview

The SPaT Challenge

A challenge to state and local public sector transportation infrastructure owners and operators 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 of the 50 states by January 2020.  SPaT broadcasts are expected to be accompanied by MAP and RTCM broadcasts.

The Crash Avoidance Metrics Partnership (CAMP) LLC V2I Consortium, a group of several automakers has developed a key resource titled the SPaT Challenge Verification Document.  The intent of this document is to help to ensure that SPaT deployments are performed such that the data broadcast (SPaT and MAP messages, and position correction) are compatible and meet the minimum requirements to support the on-board applications that may be released by automobile manufacturers.  The focus of the SPaT Challenge Verification Document is on ensuring compatibility with future Red Light Violation Warning (RLVW) applications.

Let Us Know You Are Actively Pursuing the SPaT Challenge

We’d like to hear from every agency who is participating in the challenge. This will allow us to update our national map, and help encourage peer to peer exchange of information, please provide the following information in an e-mail to nocoe@transportationops.org

  • Name, email, phone of local contact
  • Corridor Location (City and state)
  • Pin Location (intersection or lat/long)
  • Timeline for deployment (rough estimate of planned completion date)
    • # of interesctions that are operational
    • # of intersections that are planned to be operational in 2018/2019/2020
  • Description (1 paragraph summary of what your agency is doing e.g. “SPaT broadcast at 20 intersections with MAP planned initially and RTCM to come in the following year, goal is to support Red Light Violation warnings”)

Update Us On Your Progress

The SPaT Challenge is an initiative of the V2I Deployment Coalition, led by AASHTO, ITE, and ITS America.  A variety of resources and guidance to support you are available at this website.  In addition, a number of ITE Technical Committees have offered to respond to email questions from any agency interested in the SPaT Challenge.  Questions may be submitted here.
