An interesting article on car to car networking.
What amazing me though is the investment apparently required:
The biggest hurdle most cities and counties will face in installing these kinds of systems is likely the financial hit. The GAO study noted that the cost of roadside V2I equipment “could range between $25,000 and $30,000 per installation.” And that figure doesn’t include the backend costs of operating and maintaining them.
I struggle to believe this, when groups of engineers can kickstart projects and hit mass production, which solve similar problems using off the shelf components at a $200 or less pricepoint.
Obviously it's a little different in terms of reliability, but you can get an ODB II plus Ardunio machine for as little as that guy is managing, how much does it really cost to swap out the radio components and beef up the processing power?
