Online traffic information service, Trafficmaster has made its service available to Macintosh users for the first time.

The site features a scrollable and zoomable map of the UK, and offers detailed traffic information that's updated every four minutes. Information includes weather conditions, gridlock reports, and delay warnings.

Trafficmaster also provides "dynamic" information for registered users, providing traffic information by email, SMS (short messaging service) and WAP.

New users are being offered a free one-month trial. The service costs £34.95 annually, or £8.95 quarterly.

Trafficmaster's decision to implement Mac OS support is in marked contrast to many major services that fail to support the platform, including Asda.
