sfbikeshare

This repo contains code and data relating to the Bay Area bike share. As of now I have a KML and geojson data set of the proposed bike share stations for the launch of the program and some jam that was released to help people participate in a "Open Data Challenge". see http://bayareabikeshare.com/datachallenge and for the files that would fit on github see the babs-open-data directory. Also in ./babs-open-data are some scripts for dealing with the live stream of bike share data.

As usual I didn't finish anything super amazing by the due time but hopeufully won't stop me or you from making something cool from it soon.

So all I made was a little bar chart bl.ock: http://bl.ocks.org/mpmckenna8/11305775 and some trying to set up a few avenues for investigating a using the data further.

See http://bayareabikeshare.com/stations/json for a data feed.

I hope to provide this data in other formats as well as other datasets relating to the Bay Area Bike Share soon. I have made a request through Socrata that the MTA share some of their planning data.

See: https://data.sfgov.org/nominate for my nomination of bikeshare data.

So I imported a Bunch of the data into mongoDB because the files were a bit big to deal with in excel or similar jam. So I ran:

mongoimport --db bags --collection trips --type csv --headerline --file babs-open-data/201402_trip_data.csv

or the like to get it into a collection I could aggregate on. I accidently called the database bags when I meant to put babs.

For some aggregating to get the basic data for the Bar Chart and the babsTripStat.js file:

db.trips.aggregate( [{ $group:{_id:"$Start Station", numTrips:{$sum:1}} }, {$sort:{"numTrips":1}} ] )

Or if you want to just get it for a specific station ex:

db.trips.aggregate( [{$match:{"Start Station":"Evelyn Park and Ride"}}, { $group:{_id:"$Start Station", numTrips:{$sum:1}} }, {$sort:{"numTrips":1}} ] )

Then I did some other jam to get the dataset in the bl.ock.

A aggregation doo-dah I thought also looked interesting showed the most popular too from combos:

db.trips.aggregate( [{ $group:{_id:{fromStat:"$Start Station", toStat:"$End Station"}, numTrips:{$sum:1}} }, {$sort:{"numTrips":1}} ] )

I also made a brief start looking into the data feed but just got to putting it all in a nice array using the request node module. That script is BABSd.js but I hope to build more on that....

Scripts for BABS stream


Run any of these using node [filename] at your bash or whatever shell.

BABSd.js
  Uses the node.js request module to simply print the result of a call to the bike share station json feed.

babs2file.js
  Takes the data from the loaded page and creates file titled babsD + Date.now().json w/ the objects representing the stations all up in a nice array.

babs2file1.js
  This does the same as babs2file.js except only returns one name for the file.

Plus I made a BABS stations geojson dataset w/ the new .csv provided (pretty much by dragging it into geojson.io). Hopefully I can attach interesting data to those points if I ever get to the point I want to map anything. See:

./babs-open-data/babsStations.geojson

Go ride a bike in SF or help me out with this stuff cause I don't much know what I'm doing.
