8. Understanding Dash's Traffic Data

Figure 44: Understanding Dash's Traffic Data

What makes Dash's traffic data different from all the other GPS devices that advertise real-time traffic capabilities? Dash uses a combination of data sources and intelligent logic to create a more detailed, accurate map of the traffic in your area.

Specifically, 3rd party traffic data provider Inrix supplies Dash with base traffic information in 106 metro areas in the United States. Dash has compiled historical data models for all 106 metro areas (using the Inrix data), and preloaded that information onto each Dash Express device. On top of those two data sources, Dash incorporates the Dash Driver Network - information anonymously collected from other Dash drivers in your area.

Dotted lines on the map indicate traffic data that is either unverified or based on historical patterns. Solid lines indicate high-confidence traffic levels that are based on actual cars passing road sensors, or other Dash drivers who are on that stretch of road.

Also unique to Dash is traffic data for highway entrance/exit ramps, and surface streets. Currently no other GPS provides traffic data at this level.

Dash Express then incorporates all this traffic data in your projected ETA, and can more accurately estimate the arrival time.

9. First Impressions

I've only had 24 hours to test Dash Express, and so far I'm cautiously optimistic at the thought of never getting stuck in traffic again, not to mention being able to perform Internet searches from my car. Dash Express is big, heavy, and requires a monthly service fee to use all the features, which will no doubt give some buyers pause. But if Dash can successfully deliver on its promise of real-time, accurate traffic data in a package that's easy to use, as well as Internet connectivity for unlimited Points of Interest (POIs), Dash Navigation just might change the value proposition of GPS navigation.

Over the next week I'll be completing the full formal review, including routing engine and usability testing, Dash's MyDash web portal, connectivity features, and much more.

Dash Express is available for purchase at Amazon.com for $399, and requires a monthly service subscription to leverage traffic and Internet connectivity features. 3 months of service is included for free, after which monthly service plans cost between $9.99 and $12.99 per month, depending on how many months you commit to.

Stay tuned for the full, expanded review of Dash Express next week.
