Signal Phasing And Timing (SPAT) is a major V2I component within US DOT’s future Connected Vehicle architecture. SPAT defines how onboard systems within Connected Vehicles communicate to roadside equipment within traffic signal control systems. Dr. Zhang is introducing a research project conducted at Saxton Transportation Operations Lab at FHWA’s Turner Fairbank Highway Research Center during his sabbatical leave as a professor at Mississippi State University.

There are two major parts in Dr. Zhang’s research. The first part is to establish an open source communication/hardware-in-the-loop traffic simulation test bed so applications utilizing the SPAT messages can be modeled, developed, debugged and evaluated with real world communications and traffic control hardware. It is anticipated that the test bed can be used by other connected vehicle researchers as well.

In the second part, Dr. Zhang has explored SPAT applications and will demonstrate the safety and environmental benefits. In his presentation, he will present the queue management prototypes and corridor progression prototypes to improve mobility and dilemma zone applications to improve safety.
