Tracking Traffic Jams With Cell Phones 130
kaufmanmoore writes, "Companies and governments are looking to alternatives to expensive radars and road sensors to track traffic jams. Two Atlanta-based companies are aiming to use data from wireless carriers to mark how fast phones are moving and overlaying that with maps to calculate traffic conditions. One of the companies, AirStage, has already partnered with Sprint-Nextel and the Georgia DOT to cover Atlanta's notorious traffic. The plans raise obvious privacy concerns over the usage of the data of your cell phone's location and the accuracy of this data." From the article: "[The] systems rely on wireless companies allowing them to process the data from their towers that calculate the position of each phone about twice a second when it's being used and once every 30 seconds when it's not. [One company's technology] can track vehicles to within 330 feet without using Global Positioning System satellites. Its software is designed to weed out the difference between pedestrians and drivers, then crunch it into detailed color-coded maps that show average speeds along roadways."

Spaghetti Junction anyone or 35+ mile commutes? (Score:2, Informative)
And what gets me isn't so much as the capacity of the roads here, they've just ingeniously devised such wonderful bottlenecks (Spaghetti Junction [wikipedia.org], 75s/285e and the fact that it faces directly into the Sun during the summer months, The downtown connector [southeastroads.com] where i75/i85 merge) and they work slower the poured molasses in the frozen arctic. I live up 575 [southeastroads.com] and since May they've been working on an building a lane from Exit 7 to Exit 8 (1 mile) which would allow a large portion of the bottleneck there to avoid merging with continuing traffic, and they are still not done! And lets not forget GA 316 [southeastroads.com]... Though that's a nightmare, when they start construction on it, hell on earth would be a description...
This brings another part of the Atlanta metro area's traffic into light... The non-highway roads are extremely screwed (and most of them named Peachtree) to the point it's easier to get on the freeway for one mile and take the 10 minutes to go that one mile, than it is to drive the city streets, which can take you 5 - 10 miles to get to the same point and are a convoluted mess worse than the highways here.
And about the Norther Arc, that would have been great. I commuted 55 miles one way (I refuse to live Gwinnet County) and Highway 20, which is one lane each direction has fully loaded semi trucks driving from Canton to Lawrenceville. Couple that with school buses and it's not unheard of to take an hour and 45 minutes to go Highway 20. If an accident happens on Highway 20, you're screwed. Without GPS navigation or extremely decent maps (and the ability to read them) you will not be able to get around the accident and even if you get to a point that you can turn off to get around that accident, following the country roads can take a half hour to go a few miles up the road to get around the accident. Country/County roads here make absolutely no sense and you don't know you're coming up on the road you need/want until you have nearly passed it.

But fewer roads isn't going to work here in the Atlanta Metro Area... We could definitely use more intelligently designed interchanges.
As a side note: Some students at Georgia State created a video [youtube.com] to see what would happen if people here drove the speed limit.... People actually pulled off on to the shoulder to get around them...
