Car –to- car Communication Technology

---

 How would you feel if your car can talk and warn you about before any accident takes place?  You may love to  have it but at the same time these cars might remind you fairy tales or science fictions.

But now these are no longer come under science fictions. The MIT Technology review named V2V one of the biggest tech breakthroughs of 2015, predicting that it will become widely available as soon as next year. General Motors was the first major car company to commit, announcing in September that it would release a V2V-equipped Cadillac by 2017.

This new system allows cars in the same area to instantly communicate with one another over a wireless network, exchanging data about each vehicle’s speed, location and direction of travel.

With that information the system is able to decide whether there is any possibility for a crash and warn the drivers appropriately. It will warn the driver through real-time audible, visual and even tactile alerts (a vibration in the seat or steering wheel), depending on the design. In more advanced systems the system has the capability of applying breaks if a driver doesn’t respond quickly enough.

“It provides consumers with what I like to call 360-degree coverage,” said Bezzina, the senior project manager for the University of Michigan Transportation Research Institute.

After analyzing data from the pilot program, NHTSA estimated that V2V technology could prevent more than half a million accidents and save more than 1000 lives each year if implemented across United States.

Features of the V2V system

·         Intersection assist -When you approach an intersection, it alerts you if another vehicle is traveling at such a speed on a cross street that it could run a red light or stop sign and hit your car in the side. This helps prevent common and often fatal T-bone accidents.

·         Left-turn assist  - When in an intersection, it alerts you if there's not enough time to make a left-hand turn because of oncoming vehicles. This can keep you from turning even when you can't see the oncoming car.

·         Do-not-pass warning - When driving on a two-lane road, the system warns you when a vehicle coming in the opposite direction makes it unsafe to pass a slower-moving vehicle.

·         Advance warning of a vehicle braking ahead  - The system emits an alert when a vehicle that's two or more cars ahead in the same lane and possibly out of sight hits the brakes unexpectedly. This can help prevent a rear-end collision when you're caught by surprise.

·         Forward-collision warning - A warning will sound if the system detects that you're traveling at a speed that could cause you to hit a slower-moving vehicle in the rear. It will also give you advance warning of a stopped vehicle in your lane that you may not see because of a vehicle in front of you or because it's around a bend in the road.

·         Blind-spot/lane-change warning -When traveling on a multilane road, this illuminates a warning light when a car is positioned in your blind spot. It also emits a loud beep if you activate your turn signal when it's unsafe to change lanes. V2V is more accurate than current blind-spot monitoring systems that use cameras or radar and can even warn you of a car that's accelerating into your blind zone, which conventional systems can't do.

So Sri Lankans would warmly welcome this technology because this will help to reduce road accidents in Sri Lanka.
