511NY Developer Resource Area


Welcome to the 511NY Developer Resource Area. This is a free service that allows various user groups (i.e. the general public, commercial vendors, transportation agencies, researchers, media and others) to access 511NY real-time and static transportation data for use in their applications and research efforts.

Developer's Access Agreement

Please note that any use of the content found in the 511NY Developer Resource Area acknowledges acceptance of 511NY Developer's Access Agreement and 511NY Open Source Principles.


511NY Logo

The 511NY logo is a variation of the national 511 logo, a federally registered trademark owned by the American Association of Highway and Transportation Officials (AASHTO), which symbolizes the quality and consistency of the nation's 511 travel information technology, services and products.

The 511NY Style Guide provides guidance for the use of the 511NY logo and tagline for cross-promoting 511NY on other websites and materials. Use of the logo is mandatory in conjunction with 511NY and is encouraged by a national 511 Marketing and Outreach Committee. Widespread use of the logo across jurisdictional boundaries and throughout the nation enables travelers to quickly identify the commonalities associated with the service.

511NY Data Feed

The 511NY data feeds contain ‘real-time’ traffic and transit event information provided by the New York State Department of Transportation (NYSDOT), the New York

City Department of Transportation, the New York State Thruway Authority and the Niagara International Transportation Technology Coalition (Buffalo-Niagara Region).

  • The data feed includes all active incidents/accidents, construction projects, special events and camera images in New York State, which also show on the 511NY traffic and transit map.
  • The feed consolidates all publicly available 511NY Information in a single point of access.
  • The data feed is accessed through a web connection and is available in XML format. The feed is updated as individual events become active or updated. Events are also removed from the feed as they expire.

Commercial Vehicle Restriction

The Commercial Vehicle Restriction Service is an Esri REST service containing clearance and posting information for NYS Bridges and Parkways. This data contains the most up-to-date restriction information from the past 24 hours.

The ArcGIS Server REST API, short for Representational State Transfer, provides a simple, open Web interface to services hosted by Esri’s ArcGIS Server. All resources and operations exposed by the REST API are accessible through a hierarchy of endpoints or Uniform Resource Locators (URLs) for the GIS service.

 Commercial Vehicle Restriction Service REST Endpoint: Commercial Vehicle Restriction Map Server

 Commercial Vehicle Restriction API information: ArcGIS REST API Reference Manual.

Transit Schedule Data

Access to schedule data for New  York State public transportation operators is provided in Schedule Data Profile (SDP) and Google Transit Feed Specification (GTFS) formats as they become available.

Why use SDP format?

NYSDOT and other regional transit operators met to identify downstream application data needs, data requirements and business rules related to collecting, documenting, integrating  and disseminating transit service information.The SDP emerged from this effort. Please check our SDP FAQ.
