    D5 CV Interoperability Testing (DSRC)

     

    Lab & Field Tests

      Since CV/AV technology is rapidly evolving, and design standards and specifications are under development, a three-phased testing plan for the FRAME (Florida's Regional Advanced Mobility Elements) project continues. Those three phases are signal shop (lab) testing, TERL testing, and on-site testing. District Five has undergone the lab testing component for DSRC operations and continues to perform C-V2X device testing. The goal of testing is to evaluate communication between devices (primarily conversion of NTCIP to SAE J2735) and compatibility with existing infrastructure to ensure interoperability of applications across the District.   In a lab environment, the various RSUs and OBUs are tested to determine if full end-to-end communication such as basic safety messages (BSMs), map messages (MAP), and signal phasing and timing (SPaT) data are being transmitted and received successfully.  Traveler Information Messages (TIM) via FDOT's SunGuide® software testing and integration continues.

      Lab tours and presentations were conducted with the goal of providing attendees with an opportunity to see the first phase of the signal shop testing in person.  To access a copy of the presentation, click here.

      Both lab and field testing are currently being undertaken. This involves mounting the RSUs at viable intersections given the various controller types available by county.  While out on the field, the testing of the various messages described above with the addition of emergency vehicle pre-emption (EVP) as well as TSP will be done. Checks and balances will be validated to ensure that the equipment works within a "live" environment.
