Tracking Traffic with Cell Phones

From Technology Review

Researchers at the University of California, Berkeley, hope that drivers with GPS-enabled smart phones will help them gather more-accurate and up-to-date traffic data. Starting Monday, volunteers in the San Francisco Bay Area and around Sacramento will be invited to participate in a pilot program by downloading software that tracks their movements and transmits this information, via the phone network, back to a server at the university. In return, the volunteers will receive personalized traffic information on their cell phones.

The idea is simple, says Alex Bayen, a professor of civil and environmental engineering at the university. “Smart phones with GPS collect data from a regular commute and send it to a central system,” he says. “The system puts the data into a mathematical model that estimates traffic in real time and then broadcasts it back to the Internet and phones.”

The researchers’ model combines traffic data collected from static road sensors as well as from volunteers’ cell phones. Participants will receive personalized information such as travel-time estimates and traffic speeds along relevant routes.

The Joshua Generation

David Remnick has a terrific essay in the New Yorker reflecting on Obama’s campaign and the role that race played in it. As with everything Remnick writes, it’s beautifully crafted and thoughtful. It ends like this:

Just a few minutes before eleven last Tuesday night, when Barack and Michelle Obama and their daughters walked out on the stage at Grant Park, and everyone around was screaming, chanting, and waving flags, the long campaign came to an end. Joy was in the faces of the people all around me, there was crying and shouting, but Obama seemed to bear a certain gravity, his voice infused not with jubilation but with a sense of the historical moment.

“If there is anyone out there who still doubts that America is a place where all things are possible, who still wonders if the dream of our founders is alive in our time, who still questions the power of our democracy, tonight is your answer,” he began.

Obama had done it one last time. Having cast himself in Selma twenty months ago as one who stood on the “shoulders of giants,” as the leader of the Joshua generation, he hardly had to mention race. It was the thing always present, the thing so rarely named. He had simultaneously celebrated identity and pushed it into the background. “Change has come to America,” Obama declared, and everyone in a park remembered until now as the place where, forty summers ago, police did outrageous battle with antiwar protesters knew what change had come, and that—how long? too long—it was about damned time.

The same issue also has an interesting article by David Grann pondering how John McCain — a fundamentally decent man by all accounts — will recover from running a campaign which betrayed all his former principles about not taking “the low road” adopted by George Bush and Karl Rove when they destroyed his Primary campaign in 2000. Did his graceful concession speech come too late to rescue his self-respect? How can he live with himself, given the way his campaign developed into the hate-fest of the last few weeks? We will see.

This is interesting — Google Flu Trends…

We have found a close relationship between how many people search for flu-related topics and how many people actually have flu symptoms. Of course, not every person who searches for “flu” is actually sick, but a pattern emerges when all the flu-related search queries from each state and region are added together. We compared our query counts with data from a surveillance system managed by the U.S. Centers for Disease Control and Prevention (CDC) and discovered that some search queries tend to be popular exactly when flu season is happening. By counting how often we see these search queries, we can estimate how much flu is circulating in various regions of the United States.

There’s a nice animation on the site showing how official health data lags Google searches.

The NYT has a report on this today.

Excerpt:

Tests of the new Web tool from Google.org, the company’s philanthropic unit, suggest that it may be able to detect regional outbreaks of the flu a week to 10 days before they are reported by the Centers for Disease Control and Prevention.

In early February, for example, the C.D.C. reported that the flu cases had recently spiked in the mid-Atlantic states. But Google says its search data show a spike in queries about flu symptoms two weeks before that report was released. Its new service at google.org/flutrends analyzes those searches as they come in, creating graphs and maps of the country that, ideally, will show where the flu is spreading.

The C.D.C. reports are slower because they rely on data collected and compiled from thousands of health care providers, labs and other sources. Some public health experts say the Google data could help accelerate the response of doctors, hospitals and public health officials to a nasty flu season, reducing the spread of the disease and, potentially, saving lives.

“The earlier the warning, the earlier prevention and control measures can be put in place, and this could prevent cases of influenza,” said Dr. Lyn Finelli, lead for surveillance at the influenza division of the C.D.C. From 5 to 20 percent of the nation’s population contracts the flu each year, she said, leading to roughly 36,000 deaths on average.
