FlowingData brings us a neat animation created by Waze, Gray Area Foundation, and Nik Hanselmann showing 24-hours of traffic in Los Angeles.
It starts at 5pm, right in the middle of rush hour, slows down in the late hours, and then of course picks up again around 7am, as people commute to work. Red dots indicate high levels of traffic and green dots indicate hazards, which I assume are accidents. Watch the day unfold in the video below.
I assume most of this data comes from Waze’s mobile app for navigation. They allow users to contribute information on accidents and hazards, as well as tracking traffic usage and merging in other external sources. I’m not sure what the “flashing” roads mean in the visualization tho. Ideas?
The New York Times and Sense Networks have combined efforts into building an interactive mashup of taxi tracking data with Google Maps to create an interactive heatmap of taxi stops across Manhattan Island.
Information from millions of taxi trips provides a telling record of the city’s vital signs. The map shows the average number of pickups for different times of the day and days of week, Jan. – March, 2009.
Somewhat odd that the data is from a year ago, that might possibly be a typo (and it’s actually Jan – March 2010). You can see some interesting trends, including the basic rush hour, lunch rush, and late night traffic on Friday and Saturday night.
Pedro M Cruz’s master thesis maps the traffic patterns of over 1500 vehicles over a month in Lisbon, visualizing the results in a variety of informative and aesthetically pleasing ways.
This post presents several experiments (piked between a total of more than 20 generated artifacts) that map 1534 vehicles, during October 2009 in Lisbon, leaving route trails and condensed in one single day. Therefore, the artifacts are animations of the traffic evolution in Lisbon during 24h (from 0:00 to 23:59). In the first artifact, when the traffic is slow, red circles are drawn – traffic clots.
Hit his website for several videos using different visualization criteria and colormaps.
