Navteq Updates Its Traffic Database

If you’ve ever had a GPS unit or online mapping service tell you that an appointment was 20 minutes away by car, only to show up late for it after a 40-minute drive, Navteq’s latest update to its traffic data may help you plan ahead with a little more accuracy. The company, which provides map data to everyone from Google and Yahoo to Garmin, released Traffic Patterns North America v3.0 on Monday, which significantly refines the data these companies use to estimate drive times.

Traffic Data v3.0 includes updates to nearly one million miles of roads in the United States, Puerto Rico and Canada. Navteq gathered the data using GPS probes and sensors, building a database of which roads get blocked up, how badly, and when. As a result, the company claims that estimates made using its data are now 33 percent more accurate than those using posted speed limits alone.

The database even accommodates for rush hour and holiday travel. “For example, NavteqTraffic Patterns details specific road segment speed information that can indicate daily congestion on I-94 in Chicago between 9 and 10 a.m. instead of relying on the posted speed limits,” said Navteq ‘s vice president of traffic, Howard Hayes.” By matching the traffic data to location markers in our map and driving thousands of miles of roads to test for accuracy, Navteq Traffic Patterns offers a comprehensive, high quality solution for application developers to offer more routing features for today’s navigation products."

Although not a consumer package available for purchase or download, mapping services that adopt the new package will reflect the improved results in their route planning.

Tesla Powerwall is the best solar, home backup, and EV charging companion

Tesla Powerwall 3 installed on outside of home

Solar power, and having solar panels on your home, is a fantastic way to conserve energy and cut down on power bills, especially if you live somewhere sunny like Florida or California. There's just one glaring issue. When the grid goes down you still lose power because of how it's connected. Your solar panels cannot generate enough energy or keep it stored to keep your power on. So, essentially, your power setup doesn't offer much benefit there, unless you get a home power backup system. More specifically, something like a Tesla Powerwall is a compact home battery that stores energy generated from the grid. That energy is then used as a backup when traditional grid power is unavailable.

To make it even more clear, with a Tesla Powerwall, the power stays on even during a major blackout or outage. It's whole-home backup, too, which means you can power your lights, appliances, electronics, you name it. If you've ever had to throw away an entire refrigerator's worth of spoiled food because of a multi-day outage -- like I have -- you'll certainly appreciate the option to keep your appliances running. But that's not all it can do. The Tesla Powerwall is an excellent companion for Tesla EV owners, creating an entire smart ecosystem of power. Let's explore.

Chamberlain myQ Smart Garage Security Camera -- $27 $50 45% off

While this is ostensibly made for your garage, there's no reason the Chamberlain myQ Smart Garage can't work for other uses as well, especially if you don't need the highest quality of recording. It has an HD camera, which isn't a ton, but it does have an impressive 130-degree field of view. The MyQ also connects through dual-band Wi-Fi for a better connection, and it even has two-way communication, which is impressive for something at this price bracket.
