In the field of self-driving cars, algorithms for controlling lane changes are an important topic of study. But most existing lane-change algorithms have one of two drawbacks: Either they rely on detailed statistical models of the driving environment, which are difficult to assemble and too complex to analyze on the fly; or they're so simple that they can lead to impractically conservative decisions, such as never changing lanes at all.

At the International Conference on Robotics and Automation tomorrow, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) will present a new lane-change algorithm that splits the difference. It allows for more aggressive lane changes than the simple models do but relies only on immediate information about other vehicles' directions and velocities to make decisions.

[...] One standard way for autonomous vehicles to avoid collisions is to calculate buffer zones around the other vehicles in the environment. The buffer zones describe not only the vehicles' current positions but their likely future positions within some time frame. Planning lane changes then becomes a matter of simply staying out of other vehicles' buffer zones.

[...] With the MIT researchers' system, if the default buffer zones are leading to performance that's far worse than a human driver's, the system will compute new buffer zones on the fly — complete with proof of collision avoidance.

Let me know when someone finds an algorithm that can deal with unknown situations as intuitively as human beings can. Until then...

    Hey, since we have computers controlling cars, Why hasn't anybody added a big screen between the back window and bumper, where the car could print in plain english "going to the right lane, exiting in 1 mile, thank you".
    Humans can't communicate that well from inside their cage, so we got turn signals. Autonomous cars can be explicit (not too long, for safety).

    Wow. Incredible idea. Let me tell you, I wouldn't mind that one. Although it might be a little bit dangerous. And possibly very awkward. Because the wrong person might follow you. If you weren't careful about what you showed on your "explicit" screen. They think it's you in the screen, you tell them no, it's not you, it's an actor. Doing the things you want to do.

    Some folks don't like to look at that type of screen. And they don't want other folks to look either. New York City, we used to have a red light district. Times Square, people don't know this. So many adult theaters. Until .@RudyGiuliani [twitter.com] shut them down. He brought Disney, he brought many things. You can bring your kids, take a selfie with Captain America. Very wholesome. And very profitable, trust me.

    As far as I’m concerned, there's no such thing as bad porn. There's great porn and there's OK porn. Like pizza. But .@VP [twitter.com] Pence -- great guy, beautiful guy -- doesn't like to see anyone naked. Not even his wife. And there are many many people like him. I'd love to see the cars with the very special screens. And our wonderful young people would love that. They love their screens. Folks my age have business cards. And we have fax machines. When we like someone in a very special way, we trade business cards. And we send each other very special faxes. Or we do the Snapchat, I'm very big on Snapchat. Very big. But the young folks have sex "tapes," they're the modern day business card. And I was in a few pornos (Playboy), as everyone knows. Unfortunately I didn't have sex in those. Although I had a lot off-camera. And I still do!!!
