Dash Driver Network™
Dash approaches traffic in an entirely different way – by collecting it from other people driving real commute routes, during real commute times. Each Dash Express anonymously and automatically sends its position and speed back to servers at the Dash Network Operations Center. The Dash servers then update all other Dash devices in the area with current road speeds. That way, members of the Dash Driver Network always have the best, most up-to-date traffic information available.
Better out of the box
The larger our network grows, the better traffic information becomes. However, even the first Dash devices in an area get traffic data that's superior to other GPS devices. That's because Dash devices receive traffic info from road sensors, commercial fleets and other sources through our partnership with Inrix, the premier traffic data provider in the U.S. Starting with the first devices in each market, Dash adds further value by using these initial cars to calibrate the sensor data. This lets Dash assign it a high (straight line) or medium (dotted line) confidence rating, giving you all the information you need at a glance.
Better down the road
In addition, Dash frequently updates each Dash device with the most comprehensive historical traffic database in the industry – a combination of third party and Dash driver data. Dash knows how fast every road segment you drive historically moves during each of 672 separate 15-minute time periods during the week.
The Network effect
Dash Express users will begin to see the benefits of the Dash Driver Network with only a few devices in a given market. And every additional device in the area just makes the network better. It takes a surprisingly small number of drivers in a major city for the Dash Driver Network to provide live up-to-the-minute data for most roads during commute hours.
More than just highways
The Dash Driver Network allows us to provide coverage on nearly 2 million miles of US road, and provides the only source of live traffic flow data for surface streets in addition to highways. And on highways, Dash Driver Network data is much more extensive and accurate than other GPS devices. In addition, our traffic model itself tracks approximately ten times more road segments than any competitive products.
TruTraffic from Dash: it's the best solution
All of this adds up to the best traffic data in the industry. The kind of timely data you need to make good driving decisions, as well as accurately estimate and track your arrival time once you've selected your route.
