It is typically digitally coded using the FM-RDS system on conventional FM radio broadcasts. It can also be transmitted on DAB or satellite radio. It allows silent delivery of dynamic information suitable for reproduction or display in the language chosen by the user and without interrupting normal audio broadcast services. Services, both public and commercial, are now operational in many countries worldwide. When data is integrated directly into a navigation system, traffic information can be used in the system's route calculation and the driver can have the option to take alternative routes to avoid traffic incidents.
