In car sat nav is becoming a rapid reality in Ireland with the widespread availability of units from electrical retailers. The higher specced units from companies such as garmin and TomTom offer a TMC facility.
The Traffic Message Channel (TMC) is a specific application of the FM Radio Data System (RDS) used for broadcasting real-time traffic and weather information. Data messages are received silently and decoded by a TMC-equipped car radio or navigation system, and delivered to the driver in a variety of ways. The most common of these is a TMC-enabled navigation system that can offer dynamic route guidance – alerting the driver of a problem on the planned route and calculating an alternative route to avoid the incident.
TMC is not supported in Ireland. Traffic updates are a necessity for commuters this is evident as all the major radio stations have AA traffic update slots on their radio programmes. A TMC map of Western Europe highlights the fact that Ireland is the only country in Western Europe that has no plans or does not support this facility.
In order for TMC to become a reality the Irish Government need to fund this venture so that a private company such as the AA can be employed to provide the information and have it relayed by the national broadcaster such as RTE radio.
