Siemens Intelligent Traffic Systems will provide Connected Vehicle (CV) solutions in the form of Roadside Units (RSU), On-Board Units (OBU), CV applications, and RSU central management software for Gainesville, Fla.’s Trapezium Signal Phase and Timing (SPaT) project, which will be one of the largest state-funded SPaT CV deployments in the U.S.

The project will take place along the four-road area surrounding the University of Florida, descriptively called “the Trapezium” — covering 27 intersections. The university environment surrounded by this area provides a rich spectrum of automobile, transit, bicycle, and pedestrian activity and is an ideal location to further examine and quantify the significant benefits of CV technologies.

The project is expected to be completed by 2021, and is planning to include the following CV capabilities:

  • SPaT MAP Display Signal Timing, signaling remaining time to a Green signal
  • Red Light Violation Warning
  • Wrong Way Entry (WWE)
  • Exit Ramp Deceleration Warning (ERDW)
  • Curve Speed Warning (CSW)
  • Emergency Electronic Brake Lights
  • Forward Collision Warning
  • Intersection Movement Assist
  • Work Zone Warning
  • Do Not Pass Warning
  • Speed Limit Warning

These are applications that have already been successfully tested in other cities. This technology has been previously installed in the state of Florida and has been proven to be interoperable and compatible with third party devices.

Siemens’ history with DSRC communications and CV applications in the U.S. extends back to 2007 with its involvement with the USDOT Connected Vehicle Test Bed in Oakland County, Michigan. This was a testing environment intended to advance the state of ITS practice by providing a cutting-edge model operating environment for CV and DSRC. Siemens was one of the first controller manufacturers to output SPaT data at the testbed.

Siemens Mobility has been supplying traffic-related products and services to FDOT, as well as local municipalities in Florida for over 40 years. Most recently, Siemens Mobility has been the primary CV technology partner in the high-profile Tampa Hillsborough Expressway Authority USDOT Connected Vehicle Pilot Project, supplying over 40 RSUs and driving the development of 13 V2I and V2V applications.
