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. http://tlrobinson.net/projects/haightcam/traffic.png (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) That first…
That's neat. I used to live in Ann Arbor, which is a quiet student town that gets very crowded on football weekends. It would be interesting to make up a game that makes users match unlabeled traffic graphs to the towns or neighborhoods where the graphs were generated.
