@vasanth kumar d: Yes. I do know about PIXY. Great project with innumerable applications...

I know -- I pledged to th eKickstarter campaign -- I cannot wait for my Pixy to arrive -- that's one reason why I'm working on learning the Arduino so i can use my Pixy on an Arduino-controller robot...

Yes. I do know about PIXY. Great project with innumerable applications. I am excited to know that future version of PIXY would have face tracking capabilities.

You are right so my point is, if the car manufacturer itself designs ADAS it may tend to reduce the overall price of the car, that's why I was asking about Mitsubishi as that is the alone company who is in electronic system development along with car manufacturing.

The local automobile manufacturer have a lot of influence on the local laws. Eg emission rules are very everywhere. But i agree that extra technology or gadgets are going to increase the overall ownership cost of the vehicle.

We already have a lot of vision assistance in vehicles eg reverse, side parking. Radar or any other system which can detect the collision trajectory of other vehicle/human much in advance or take action will be greately helpful.

Indeed, as jaybus0 stated, an infrastructure system is a huge public works project involving multiple government entities. Even if funding could be procured -- a highly questionable proposition -- the high cost & long schedule would not bode well for improving driving safety any time soon. It is far more effective to deploy safety systems on the vehicles themselves.

In my opinions,

Radar is more real-time with less computational processing

Vision is more reactive and require computational grunt.


Personally, i take both! That's this field of data sensing call data fusion, if you want to reduce uncertainties and improve measurement confidences. You want both. Along with GPS, inertial, wheel RPM measurements i.e dead reckoning.
Otherwise, it's not complete to me.

Given that most signs (in the US anyway) are standardized (think STOP signs) it should be an easy task for vision to pick them out (even in poor visibilty conditions - snow covered stop sign) and alert the driver.  Even with a low quality GPS system I was made aware of both my speed and the "posted speed limit" in almost real time.  If GPS was improved and kept up to date on speeds and hazzards then GPS would be a very easy way to be more road aware.  That said, having driven a rental car with back up vision assist and blind side (and back up) radar I loved it!  I would be willing to pay more for my next car with those features, esp. given my new / young drivers in the family.

@vasanth kumar d: I would prefer a vision based system...

Machine vision is coming along in leaps and bounds -- did you see Caleb's article on the low-cost Pixy Vision System and my related article on Learning the Arduino?

I would prefer a vision based system if cost is a big deciding factor. Because the advantages of a vision based system is far too many compared to the disadvantages associated with it.
