Brown had 16 receptions for 189 yards and two touchdowns, including the game-winner in the fourth quarter. -RUSHING OFFENSE: C. Pittsburgh took over the No. 6 seed by holding the tie-breaker over the Jets, which is now the first team out of the playoffs.

The information will then be sent to data centres that automatically update and generate high-precision road maps that cover a wide area.

The tone of comity was a departure from the spiky ideological clashes that rumbled through the latest GOP debate on Tuesday. The Bernie Sanders, Democratic National Committee drama has been resolved – for now.

Conventional road data gathering relies on specially-built vehicles with three-dimensional laser scanners.

It involves the night I saw Santa. “Back in 1974 my mom had a long green plaid maxi dress, so I wanted one to match hers”. This year on Christmas, I will be spending time with my close ones, dining out with them and spending some quality time.

Toyota’s system will try to gain a better understanding of actual road layouts and traffic rules, including speed limits and road signs. Also, it says that “precise measurement of vehicle positional data requires the collection of information on dividing lines, kerbs and other road features”. Toyota would be using a whole fleet of map generators on the roads, the auto maker believes that the power of having many cars out there on the roads, will make up for the lack equipment that Google and Apple use for their maps.

Toyota says that traditional mapping, as used by most sat-navs and GPS systems is of limited use due to the “infrequent” nature of the data-collection method – essentially, the maps aren’t updated often enough. We’ve already learnt that the Ford GT will be the Official Vehicle of CES 2016, and now we can also reveal what to expect from Japanese automaker Toyota at the show.

Toyota stated “the system’s margin error [is limited] to a maximum of 5 cm on straight roads”, in a press release and that the tech would be phased in for highway use only but eventually ramped up to, well, everywhere.

Initially the company is planning to use the system in expressways, and it plans to develop its functionality to cover ordinary roads and assist in hazard avoidance. Toyota plans to work with mapmakers to improve both its and their maps in a bid to improve services offered to both private and public sectors. A vehicle’s integrated cameras and Global Positioning System sensors collect road images and location information on the fly.

The company’s system will be included in automated driving vehicles that will be available for purchase by the year 2020. This way they can warn other drivers of potholes and to avoid them.
