We built out a quick visualization of the noise data we've been collecting in the city. Again, the link is here: <a href="http://tendernoise.movity.com" rel="nofollow">http://tendernoise.movity.com</a>.<p>Our goal for this noise project is to show the affect of noise (from muni, cable cars, bars, people) on the quality of life. We're going to collect and scale the data to other neighborhoods shortly.<p>It's v.1, so let us know what you think.
Cool. I did a traffic visualization from my apartment on Haight Street on New Years Eve and the first week of January this year. I just had a webcam with some software to detect movement in the middle of the intersection.<p><a href="http://tlrobinson.net/projects/haightcam/traffic.png" rel="nofollow">http://tlrobinson.net/projects/haightcam/traffic.png</a><p>(My R skills aren't great, sorry it's not pretty. The camera also got blocked for awhile around day 5 so it's not exactly scientific)<p>That first cycle starts mid day on New Years Eve. You can see a big drop in traffic leading up to midnight, then a big increase soon after. Not surprising, but it's always a little gratifying to confirm a hypothesis.
Perhaps you could find people that are willing to install these sensors outside their windows. You could run them from a power adapter to get more than 3 days worth of data collection + less hassle from cops.
If you are moving this project into the Tendernob and need a place to put equipment on Pine St, I'd be happy to help out.
This is really cool! Having lived in the Tenderloin, I can testify to the impact of its noise on my quality of life.<p>How is the project being funded? What does it take to install the data capturing equipment? How do the interactions with the city or property owners go?
I'm wondering if there's a way to crowdsource this with cellphones. I realize it's a little out there, but there <i>are</i> thousands and thousands of microphones already blanketing every urban area ...<p>edit: Google informs me of <a href="http://www.noisetube.net/" rel="nofollow">http://www.noisetube.net/</a>
Just a couple days ago, I was thinking it'd be cool to have a "noise" layer on Google Maps, but I figured it would be too hard to get good resolution over a large area.
I would suggest that the data is more useful when combined with information on the negative effects of noisy environments. For instance see <a href="http://www.designshare.com/research/lmaxwell/noisechildren.htm" rel="nofollow">http://www.designshare.com/research/lmaxwell/noisechildren.h...</a> for some information on impacts of noisy environments on children's ability to learn.
wow , just today I was thinking about similar idea.
Crowd sourcing air pollution.
Adding some small device to your smartphone(andruino with android) that sniffs the air
and analyzes the pollutants ,etc. Then sends it back to the server and can visualize it.
About a thousand users in a big city would be enough .
Not only just to see it on the web, but for example
city traffic lights can divert cars depending on the polluted area,deciding where to buy/rent a house
Very cool project. It seems like getting every other intersection might be overkill? I'd be more interested in something sparser that covers more of the city.
