+ - Traffic lights: There's a better way

Submitted by stephendavion
stephendavion (2872091) writes "MIT researchers develop an improved system for timing of urban lights to minimize commuting times. Anyone who has ever driven a city street and been frustrated by having to stop again and again for red lights has probably thought that there must be a better way. Now, researchers at MIT have developed a means of computing optimal timings for city stoplights that can significantly reduce drivers’ average travel times.

Existing software for timing traffic signals has several limitations, says Carolina Osorio, an assistant professor of civil and environmental engineering at MIT. She is lead author of a forthcoming paper in the journal Transportation Science that describes the new system, based on a study of traffic in Lausanne, Switzerland."

Nothing against a utility promoting itself by pointing out what it has achived, such things do need community support. However promoting the current CEO is clearly a form of political advertising for the benifit of the CEO, not the utlility. The full amount should be recovered from the CEO, after he is sacked for (legalised) embezzlement.

Nothing wrong with subsidies provided everyone is subsidised equally. Subsidising FF and renewables is not the same thing, FF are already have a huge subsidy in that it costs nothing to pollute the commons. Any moron can construct a free market via regulation, the hard part is constructing one that doesn't eventually kill us with our own greed.

Objects cannot move relative to each other faster than light but the space between them has no such restriction. Hyper Inflation lasted until the universe was about the size of a basketball. The big bang didn't end with (hyper) inflation, it is still happening and the universe is still inflating. The boundary to our modern universe is expanding away from us at the speed of light. So, two observers on opposite sides of our visible universe will be speeding away from each other faster than light. Only an observer in our position can see that the two observers at the opposite "edges" existing simultaneously.

Big fan of Starts with a Bang for many years, I must ask Ethan why cosmologists have ruled out the idea that our universe is the interior of a black hole. Neil deGrasse Tyson claims Einstein's equations can be interpreted to mean there is a different universe inside a black hole but he doesn't elaborate. If anyone else knows of a good reason as to why our universe can't be the interior of a black hole then I'd love to hear it.

Yep, and no matter what you think of Edison, the modern research lab was primarily his invention. A modern lab tends to know what it is looking for (eg: practical light bulb) and is all about the finding the steps to get there (trial and error), compared to say Newton who mainly followed his own curiosity. The trick to being a lead researcher is finding a rich problem space for the students to work on that will attract grants.

If what they've been doing hasn't solved the problem, tell them to do something else. -- Gerald Weinberg, "The Secrets of Consulting"
