Cars talking to each other

Today I read this news via Engadget

I have read before about car-to-car or vehicle-to-vehicle communication, and apparently the US Department of Transportation is way ahead. V2V “allow cars to share information about their position, speed and heading with each other and alert a driver when there is potential for danger. That could be a car speeding through an intersection ahead or a truck in your blind spot when trying to change lanes.”

These systems have been mentioned in here because this study tries to find the optimal time and place to show potential alerts. V2V may bring great benefits to road traffic, but before the technology perfects itself, we should have well established the ideal time to activate alert systems.

Today I read this interesting study, exactly about that.


IVIS, If only everything remained the same…

Porter, B.E. (Ed.) Handbook of Traffic Psychology. Elsevier Inc.

While reading the chapter on Ergonomics and Human Factors I found the statement I was looking for. It’s hard to find definite answers of course, but since the first time I heard about In-vehicle information systems (IVIS) I wondered if they really were effective.

Although the safety potential is huge, the ultimate effects are definitely smaller than expected. If these systems are included in the vehicle, they would work perfectly if everything remained the same. But when one thing inside the vehicle is changed, this will inherently change the behavior of the driver: everything is connected.

Some of the possible negative effects of the IVIS – the book mentions ITS, Intelligent Transport Systems – are:

1)      Underload and diminished attention level;

2)      Information overload (Google Glass and all AR things, please do watch out);

3)      Incorrect interpretation of information;

4)      Overreliance on the system;

5)      Risk compensation.

This is definitely interesting, although quite intuitive for anyone with minimal knowledge on cognition.

Do engineers consider this when they conceive these systems? I know nowadays most of them have psychologists or ergonomists on their teams, but some of them still don’t.

And these systems worked rather well on aeronautics contexts, but it seems as if they were blindly applied to the automotive sector.

More on this on the future, definitely.
