Using WiFi to Create Smarter, Safer Cars and Intersections

A few weeks ago, I wrote that your next car might just have its own IP address. Besides talking to the Internet, though, there is also a lot of utility in using short-range networks that can link multiple cars together into a single, ad-hoc network and alert drivers of potential hazards. Today, Ford announced a new initiative that will rely on short-range WiFi signals to enable cars to create local networks to exchange data about their positions and speeds to avoid accidents.

Of course, this system only works once a lot of cars and manufacturers offer this feature and agree on a standard, but as the video below shows, there is a lot of potential for this. Cars that can talk to each other (and maybe even get traffic information from local “smart” intersections or highway on-ramps) don’t have to rely on expensive systems like radar. Instead, just basic GPS information, coupled with an ad-hoc WiFi network and some smart software could, as Ford puts it, “warn drivers if there is a risk of collision when changing lanes, approaching a stationary or parked vehicle, or if another driver loses control.”

Not Just Smart Cars, But Smart Intersections, Too

Ford is also proposing “smart intersections” that would be able to talk to cars and be able to “monitor traffic signal status, GPS data and digital maps to assess potential hazards, and then transmit the information to vehicles.”

The company is working with other car makers and the U.S. government to create standards for bringing this technology to deployment. In addition to all of this, the company also announced that it is doubling its intelligent vehicle investment in 2011 and plans to have demonstration vehicles that offer this WiFi-based technology on the road in the next few months.
