@Road® Awarded Patent For Determining and Distributing Routing and Traffic Information

Tenth patent a method for automatically processing and delivering current and predictive traffic information to mobile workers

FREMONT, CA -- October 1, 2003 -- @Road (NASDAQ: ARDI), a leading provider of mobile resource management services, today announced that the U.S. Patent and Trademark Office has issued patent number 6,594,576 titled "Using Location Data to Determine Traffic Information." This is the tenth patent awarded to @Road and the fourth issued to the Company in 2003. @Road has 36 additional patents pending in jurisdictions throughout the world.

For companies with mobile workforces, efficient routing and dispatching is critical to the timely provisioning of products and services to customers. Knowledge of current and predicted traffic conditions is one of the keys to successful routing and dispatching operations. Today, general traffic information is typically gathered through means such as cameras disposed at primary points of a road or reporters in helicopters. In addition, mobile workers learn traffic patterns over time and many of their companies do not have a method to share effectively this information across the organization. As a result, traffic information is generally available only for certain roads, not frequently updated and not available equally to all mobile workers.

The invention upon which this latest patent is based provides for detailed traffic information to mobile workers and support personnel such as dispatchers. In addition to providing current traffic information, the patented technology can determine alternate routes as well as predicted travel times and estimated gas consumption for alternative routes. These data can be delivered to a mobile worker's PDA, cellular telephone, an @Road Internet Data Terminalª (iDTª) or to a user connected to the Internet.

According to the patent, a traffic data compilation computer periodically collects position, velocity, time and other information via wireless communications from a plurality of mobile users that are each equipped with devices that incorporate a Global Positioning System (GPS) receiver and a wireless transmitter. The compilation computer also stores posted speed limits for driving routes and can incorporate traffic information provided by conventional third party sources. Upon receipt of a request for traffic or routing information, the compilation computer determines the requestor's location (if a mobile user), processes current traffic information, compares the data to posted speed limits and historical traffic data for the location or route, prepares predictive traffic results, and then delivers the information to the requestor.

For example, mobile workers seeking traffic and routing information from one job to the next job can request the data from their mobile devices. These devices need not be the same across the organization. The traffic data compilation computer assembles the relevant traffic data and transmits back to the proper device an image of the route with a superimposed traffic level indicator showing current traffic flow and speeds (much like a bar chart). The compilation computer can also suggest, at the mobile worker's request, quicker alternative routes according to then-current traffic data.

"We are continuously seeking ways to provide our customers with technological advancements in mobile resource management," said Krish Panu, president and CEO of @Road. "In addition, we believe that adding this latest invention to our growing patent portfolio strengthens our position as one of the leading MRM service providers."
