Intelligent transport systems - Cooperative ITS - Using V2I and I2V communications for applications related to signalized intersections

Scope

The scope of this technical specification is to define messages and related data
structures and data elements for the following exchanges between roadside
equipment and vehicles:
- Definition of the SPaT (signal phase and timing) message transmitted from a
traffic controller that describes the state of the signals, signal timing as necessary
to support the applications identified herein. This will typically include such
information as the passage time, permitted movements, future movements
permitted, etc. The SPaT message is dependent upon the MAP message.
- Definition of the MAP message (which include the definition of motorized lane,
vehicles, busses, trams, bicycle, pedestrian crosswalks, etc.)
- Definition of the messages to be exchanged between an intersection traffic
controller and approaching vehicles (SRM, SSM) to support priority treatment as
might be expected for special vehicles,such as emergency vehicles,freight
transport, and public transport vehicles to improve safety, and operational and
environmental efficiency.
