DD ENV 12315-1 is the first part of the multiple series that provides a common message structure for Traffic and Traveler Information messages which are disseminated via dedicated beacon infrastructure (for short-range communications, only).
It, therefore, DD ENV 12315-1 provides the framework to enable the providers of information services to utilise such a means of dissemination to supply information to a large number of equipped vehicles, together with the suppliers of such in-vehicle equipment to receive, process, and/or display the messages to the traveller (driver or passenger).
DD ENV 12315-1 on TTI messages via dedicated short-range communication is useful:
Traffic and Traveller Information may be disseminated through a number of services or means of communication, covering static displays, interactive terminals, and in-vehicle equipment.
DD ENV 12315-1 specifies the data specification for an air interface via dedicated short-range communication, whereby the information is produced at a central location (known as the in-station, central office, or traffic information and control centre) and disseminated via a network of roadside beacons. This will assist you to enables messages to be exchanged between different systems and service providers adopting a variety of applications’ specifications.
Overall, DD ENV 12315-1 includes route guidance data, messages, and warnings, car park information, park, and ride information and “yellow pages” directories of other services. DD ENV 12315-1 assists you with all discrete data sets which comprise TTI.
