System Description: Boston's Central Artery/Tunnel, owned by the Massachusetts Highway Department, is the largest and most complex highway project ever undertaken in an American city. The project transforms downtown Boston as the aging and overly congested elevated expressway is replaced with a new underground interstate system and a third harbor tunnel. Opened in 1995, the new Ted Williams tunnel extends the Massachusetts Turnpike under Boston Harbor to provide improved access to Logan International Airport.

Transdyn is delivering the Integrated Project Control System (IPCS) that monitors and controls all aspects of over 150 lane-miles of highway and twenty major operations, emergency response, ventilation, and electrical distribution facilities. To maintain life safety and optimal traffic flow, the IPCS constantly monitors the roadway and facilities and generates computer-managed responses to traffic incidents and other adverse conditions.

In addition to the IPCS, Transdyn also provided the DYNAC® managed Surveillance and Access Control/Intrusion Detection System (AC/IDS) for the tunnel. The system uses smart video analytics to provide facility monitoring and incident detection. Cameras are automatically controlled using pre-shots and tours to cover areas where incident and intrusion alarms are detected.

The AC/IDS furnished for the project is a network-wide system designed to monitor and control access to the entire facility and infrastructure complex including secure areas, buildings and vehicle parking facilities. The system also controls dispensing of vehicle fuel and detects unauthorized opening of building doors, windows, system control panels, etc., as well as unauthorized persons in the protected areas.

System Description: Operated by The Port Authority of New York and New Jersey, the Holland and Lincoln Tunnels opened in 1927 and provides a vital link between midtown Manhattan and central New Jersey. The Holland Tunnel was the first Hudson River vehicular tunnel, and the Lincoln tunnel is the world’s only three-tube underwater vehicular tunnel facility. With traffic volumes exceeding 70 million vehicles per year, they are among the busiest tunnels in the world.

Operating under a joint venture contract, Transdyn was selected by the Port Authority of New York & New Jersey to design, implement and maintain an Intelligent Video System and Intelligent Transportation System (ITS) for the Lincoln and Holland Tunnels.

The intelligent video system is vital to the safe and efficient operation of these facilities. Video from CCTV is analyzed to detect traffic anomalies both inside and outside of the tunnels as well as other sensitive areas.

Transdyn's DYNAC ATMS® software automatically detects incidents, identifies stopped vehicles and implements optimal response plans. The software assists operators in rapidly responding to emergency situations, alerting motorists, clearing incidents, balancing traffic flows and mitigating congestion.

System Description: The Authority is the nation’s largest bridge and tunnel authority serving more than one million people daily. It operates the Henry Hudson, Triborough, Bronx-Whitestone, Throgs Neck, Verrazano-Narrows, Gil Hodges-Marine Parkway, and Cross Bay bridges and the Queens-Midtown and Brooklyn-Battery tunnels.

Transdyn designed and is deploying a fully integrated system aimed to strengthen security at nine MTA critical bridge and tunnel facilities. ATM IDEAS includes designing, furnishing, and integrating a fully redundant, distributed host system and software at each control center. Transdyn's DYNAC® ES ATMS software suite provides integrated surveillance and management functions at all facilities.

A new state-of-the-art video over IP distribution system broadcasts high definition video surveillance images between the facilities and the Operations Control and Communication Center (OCCC) over a high-speed wide area network. Video data from over 200 cameras is analyzed to detect traffic anomalies at the bridges and tunnels. The system provides local viewing, recording capability and digital (IP) compressed video streams for distribution to any of 11 operation centers in NYC.

At the OCCC, the software enables centralized monitoring of bridge and tunnel operations and assists in coordination of incidents and events that impact multiple agencies and facilities.

The sophisticated system allows the Authority to efficiently protect infrastructure, detect and respond rapidly to incidents and events, provide real-time advisories and monitor traffic, weather, and roadway conditions.
