A Freight Plan for the NYMTC Region<br />

Action 2 – Expand the Region’s Integrated Incident Management System (IIMS)<br />

Description<br />

The Integrated Incident Management System (IIMS) is an incident/emergency management<br />

project that enhances the coordination of multi-agency incident/emergency<br />

response and management. IIMS operates over an interconnected network linking emergency,<br />

public safety, public works, transportation operations centers, and mobile emergency<br />

responders with each other and with the incident scene. The IIMS initiative would<br />

be incorporated in a larger Advanced Traffic Management System (ATMS); NYSDOT’s<br />

existing ATMS covers 40 to 50 miles of roadway in <strong>New</strong> <strong>York</strong> City, which represents<br />

approximately 20 percent to 25 percent of the roadway-miles in NYSDOT’s jurisdiction in<br />

Region 11. The system is managed from NYSDOT’s Joint Traffic Operations Center in<br />

Long Island City and includes: 1) instrumentation to measure vehicular traffic volumes<br />

and speeds; 2) monitoring equipment for incident detection and standard emergency<br />

protocols for incident response; and 3) variable-message signs to warn motorists of<br />

changes in travel conditions.<br />

The existing ATMS covers four roadway segments:<br />

1. Van Wyck Expressway (I-678) from Grand Central Parkway to Shore Parkway;<br />

2. Long Island Expressway (I-495) from Brooklyn-Queens Expressway (I-278) to Grand<br />

Central Parkway;<br />

3. Cross Bronx Expressway from Harlem River to Bruckner Expressway (I-278); and<br />

4. Segments of the south end of the Gowanus Expressway (I-278).<br />

NYSDOT is now in the process of expanding ATMS coverage to include the entire length<br />

of the Staten Island Expressway (I-278), and is <strong>plan</strong>ning a future expansion to cover additional<br />

roadways in the Brooklyn and Eastern Queens subregions, including the Belt and<br />

Grand Central Parkways, and the Clearview, Long Island, and Nassau Expressways.<br />

<strong>Transportation</strong> Impacts<br />

By reducing incident response time and providing motorists with real time information on<br />

roadway conditions, the IIMS likely will help to reduce non-recurring congestion.<br />

Other Impacts<br />

The IIMS can improve safety and security by improving the ability of multiple agencies to<br />

coordinate their response to incidents.<br />

Responsible Organization/Action Plan<br />

NYSDOT – Continue <strong>plan</strong>ned expansion to additional facilities and agencies, including<br />

NYCDOT, NYCOEM, FDNY, NYPD and MTA.<br />
