Adaptive Cruise Control May Solve Traffic Jams

from the who-needs-'em dept

More and more luxury cars these days are coming with adaptive cruise control -- which is mainly considered a safety feature. The idea is that if you're getting too close to the car in front of you, your car automatically begins to slow down, avoiding the possibility of an accident. However, one of the nice "unintended benefits" of such systems is they may create much more efficient traffic flow. Apparently, if just 20% of the cars on the road had such systems on a normal highway, most traffic jams would simply go away. The article goes into details on how this works, but the basic summary is that most drivers are either idiots or err on the side of caution by braking too hard when someone in front of them brakes, leading to a chain reaction that causes the slow down. With a computer braking more appropriately, the chain reaction has a much smaller impact, allowing traffic flow to continue smoothly. Yet another situation where a technology designed for one purpose, actually has a very useful alternative benefit.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

    no solution

    Adaptive cruise control will not solve all traffic jams. There will still be that idiot crawling at 45mph in the inside lane.
