A day of Muni, according to NextBus

Black is less than 7mph. Red is less than 19mph. Blue is less than 43mph. Green is above that. The day is the 24 hours just before I posted it.

    Thanks!

    this is super-awesome! how did you pull all this data together? did you do it yourself, like culling stop info from nextbus? or is this data publicly available and you put together the map?

    regardless, it is pretty freaking cool.

    Thanks!

    The data is public -- see www.sfmta.com/cms/asite/nextmunidata.htm and the "vehicleLocations" request. Each time you make the request it will send back the latitude and longitude of where each bus was the last time it checked in and how long ago that was.

    This is wonderful! What software did you use?
  • Eric Fischer PRO 5y

    Thanks! I used a couple of perl scripts to process the data and write out a PostScript file, and Ghostscript to render that to a JPEG.

    Do you think its possible to create this as a layer in Google Maps?

    I love the rounded-interior corner shape created by the low sampling rate.

    Davvi Chrzastek Yes, it should be possible to apply that data to a variety of maps. NextBus already has a Google Maps version of their real-time map available from their web site. I used OpenStreetMaps so that I could layer the street and station names on top of the speed information.

    Also worth noting that depending on what your use is, you'll want to spend some time cleaning up the NextBus data. I tend to get 2-3 vehicles a day (often cable cars) that report speeds of over 100mph... and (more often) vehicles nowhere near a street.
