Thanks to everyone who came to the developers brainstorming session at
DOT on July 21. Here's a quick recap for those who couldn't come, or
weren't taking notes:
Dani Simons started with one of the underlying ideas of this
initiative: DOT has a ton of data, developers have the skills to make
great applications with that data.
Dani ran through the data feeds that DOT currently has up (
http://a841-
dotweb01.nyc.gov/datafeeds/), as well as real time traffic aggregators
that DOT feeds into (
http://www.511ny.org/traffic.aspx http://www.xcm.org/).
Dani also covered a few other data sources that aren't quite public
yet: "emergency" response emails, which alert to street closings, and
the CECM (
http://www.nyc.gov/html/cecm/html/home/home.shtml) database
of street closures.
We then opened up the discussion, including the following issues:
* Taxi data. Real time data isn't available, but they do provide a
record of 70 million trips a year, mostly in the Manhattan CBD. This
data is the province of the TLC (
www.nyc.gov/tlc).
* The importance of picking a model for sharing data, for instance as
a feed, or as a geographically-based subscription.
* The necessity and difficulty of knowing when a street closure event
is over. The agencies and utilities that do roadwork often request a
larger window than they need for work, which means that automated data
might not reflect the reality.
* The possibilities of using historic data to model traffic, which is
what Cabsense is doing with taxi data to recommend spots to hail a
cab. Historic trolley data was requested, although DOT probably
doesn't have any.
Suchitra Shetty gave an update on the Big Apps contest, which will
start again roughly this October, and finish at the end of 2010. Big
Apps is run by the NYC Economic Development Corp (
www.nycedc.com),
which shows an awareness of how tech can foster and support economic
growth.
Other issues discussed:
* The usefulness of pedestrian counts
* The potential of an API for interacting with DOT (or citywide) data.
* The legal status of DOT data - it's generally in the public domain,
although subject to licenses that focus on liability.
* The need for a continued conversation, hence this group.
I look forward to talking more and continuing this converation!
