NYC Real Time Traffic Speed Data Feed

Abstract: 

The TMC maintains a map of traffic speed detectors throughout the City. The speed detector themselves belong to various city and state agencies. The Traffic Speeds Map is available on the DOT's website. This data feed contains 'real-time' traffic information from locations where DOT picks up sensor feeds within the five boroughs, mostly on major arterials and highways. DOT uses this information for emergency response and management.

The metadata defines the fields available in this data feed and explains more about the data.

Why was the data set created?

The New York City Traffic Speed Detectors is meant to provide real time traffic speed information supplied by NYCDOT owned sensors to the general public and the developer community for use in application development. This data is also displayed in a web‐ ready format at http://nyctmc.org/.

What similar or related data should the user be aware of?

There is also a data feed for NYCDOT’s traffic cameras. Developers wishing to access the cameras via a data feed, must contact the NYCDOT TMC at TMCDOT@dot.nyc.gov and sign a data‐sharing agreement. A sample copy is provided here: http://a841‐ dotweb01.nyc.gov/datafeeds/. Other traffic and travel information for the entire state is available via New York State’s 511 program, http://www.511ny.org/

How reliable are the data; what problems remain in the data set?

linkTimeStamp indicates when data was last received from the sensor. If the date is other than the current date it indicates an error with that sensor and that data should not be used.
