Map publisher Rand McNally has launched a service that provides real-time traffic information for cellular phone users.

Rand McNally Traffic is a downloadable application that's available for Sprint PCS, Verizon Wireless, AT&T Wireless and AllTel subscribers. Once installed, the software can receive and display traffic information on accidents, congestion and lane and road closures.

The service, which covers 94 metro areas, also provides regional maps and information on public transit, weather conditions and sporting and concert events.

Rand McNally Traffic costs $3.99 a month on Sprint and Verizon, and is available to AT&T Wireless subscribers through its mMode service. Rand McNally Traffic was "coming soon" to AllTel subscribers.
