Default Mercedesí New Safety Tech Aims To End Wrong-Way Driving



Quote:
While it may seem like an unlikely occurrence, cars traveling in the wrong direction of traffic is becoming more and more prevalent. Just last year for example, even we reported on two such occurrences, one taking place in Mississippi and the other in Washington.

Back in 2009 Nissan developed a wrong-way driving prevention system called the IT-Assisted Road Information System, which basically worked using Car-2-Car and Car-2-Object communications.

Unfortunately, the infrastructure required for such systems to work outside of the lab isnít ready just yet, although much work in this area is taking place.

Since then Mercedes-Benz has come out with an alternative solution, one that will feature on its 2014 E Class and 2014 S Class models due out later this year. The system will initially be introduced to the German market, though Mercedes is working on adapting the system for use in other countries.

Mercedesí wrong-way driving prevention system relies on its existing traffic sign assistance system, which can now detect no-entry signs and issue acoustic and visual warnings to the driver should he or she stray onto the wrong side of traffic flow.

A common cause for wrong-way driving are highway ramps, where drivers either make a mistake, are distracted, or confused by complicated road designs and navigation instructions. Mercedes says its system is ideal in these situations as it will be able to warn drivers should they violate traffic regulations and ignore no-entry signs.

The technical core of the system is a camera on the inside of the windscreen. It can visually identify no-entry signs and send the information obtained to the computer in the on-board electronics. If it detects that the vehicle is about to pass the relevant prohibitory signs and is entering a highway ramp, the system warns the driver. Three loud beeps are issued and a red no-entry symbol lights up in the display in order to make the driver aware of the danger.

In order to further improve the reliability of the system, the electronics compare the data from the camera with data from the navigation system. It will also detect other signs such as speed limits and no-overtaking. The only downside is that poor weather, such as heavy snow, can render the system unavailable.

I have the solution, Mercedes. Push for more stringent standards to receive and hold a driver's license. That oughta do it.

Let's start with cars that are older than 1995 shouldn't be allowed to be driven on the road above 25 miles per hour without a special license with even more intense standards for driving such vehicles. Sounds just as reasonable as yours. Makes a lot more sense too. And then they can move up that model year when 10 years pass to a much more recent model year requirement when safety is more important than keeping people off the road.

Is there a single thread here regarding some new vehicle safety technology where it doesn't immediately turn into "people need to drive better" snob-fest?

I am pretty sure there will always be idiots, and all of us can be idiots from time to time too.

This could get ugly when using the HOV Lane going into Boston where they use the borrow a lane method from the other side of the highway.

Wouldn't work in Michigan. The signs have no consistency in placement, are generally angled wrong, wrong way signs are placed exactly between entry and exit ramps that are next to each other like a two lane road, some have bullet holes in them and most are just plain missing.

Everyone's an idiot per se in their own way technically. It's the extent and in what areas that makes each of us a certain kind of idiot.

Ironically the people who suggest others are worse drivers usually end up to be just that. That's why they can tell who are the worse drivers. They'd rather bash a way to save someone's life rather than accept their own incompetence and that they're the reason why this technology is being developed in the first place. What can you expect from a Santa that drives a PT Cruiser from 1998 anyways?



Oh sorry. I mean a 1991 Nissan.

I think they exist in their home country.
