County and City Traffic Signal Systems to Vehicle Interface Diagram

Architecture Flow Definitions

arriving train information  (Planned)  

Information for a train approaching a highway-rail intersection that may include direction and allow calculation of approximate arrival time and closure duration.

intersection infringement info  (Planned)  

Vehicle path information sent by a vehicle that is violating the stop bar at an intersection. This flow includes the vehicle's position, heading, speed, acceleration, transmission, steering-wheel angle, braking status, size information and trajectory.

rail crossing warning  (Planned)  

A warning of a train approaching or already in a highway rail intersection.

vehicle location and motion  (Planned)  

Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory.

vehicle signage data  (Planned)  

In-vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, and warnings).
