In today’s world, improved crisis prevention and emergency response plans are a necessity in protecting people and facilities. Critical infrastructure - especially confined space, limited access bridges and tunnels where delayed or inappropriate response to emergency situations can be catastrophic - require the latest, state-of-the-art technology to maximize safety and throughput.
Advanced transportation management systems can increase the effectiveness of a crisis prevention plan by identifying unauthorized stopped vehicles, monitoring critical structure areas, and responding rapidly to emergency situations with real-time decision support tools.
Transdyn has successfully delivered traffic management systems for some of the most important bridges and tunnels in the world including the Boston Central Artery/Tunnel, George Washington Bridge, and Delaware Memorial Bridge. These systems allow the operating agencies to closely monitor and adeptly control their facilities – particularly in emergency situations.
We offer total system solutions that combine traffic and facility management functions with other vital facility services into a single, robust user interface allowing staff to more effectively manage their operations, reduce congestion, and safeguard travelers.
Commonly integrated components include:

System Description: The Tampa-Hillsborough County Expressway Authority (THCEA) currently owns and operates the Lee Roy Selmon Crosstown Expressway. The existing expressway consists of a divided four-lane toll facility between downtown Tampa and Interstate 75. The THCEA is expanding the current facility by adding a reversible roadway that will provide for peak demand traffic flow between Tampa and Brandon, which is located east of Interstate 75.
This project involves design support and installation of ITS components for the operation of the Lee Roy Selmon Crosstown Expressway Reversible lanes between Town Center Boulevard in Brandon and Twiggs Street in Downtown Tampa, the Brandon Parkway gateway project in Brandon and the Meridian gateway project in the Channelside District of Downtown Tampa.
Transdyn is responsible for the design, development, integration, commissioning, and support of the Reversible Lane Capacity Improvement Project requiring a number of ITS components to manage, control and operate the roadway. The new system will integrate and automate various ITS functions such as access control gates, access control barrier nets, Variable and Changeable Message Signs, video surveillance, vehicle detection and verification, and information dissemination

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 Transportation System for the Lincoln Tunnel and Holland Tunnel.
The ITS includes new computer systems, communication systems, CCTV, sensors, and electronic signs. Transdyn’s DYNAC ATMS® software monitors traffic and roadway conditions, automatically detects incidents and stopped vehicles, and implements optimal response plans. The software assists operators in rapidly responding to emergency situations, clearing incidents, alerting motorists, balancing traffic flows, and mitigating congestion.
A fully integrated video surveillance and automatic incident detection system allows the Authority to improve incident detection and clearance times, provide facility security and maximize the throughput of the tunnel. Video signals from CCTV cameras are transmitted via fiber optics and T1 circuits to the main control center for display on workstations and a video display wall.

System Description: The George Washington Bridge, with its two-level structure, crosses the Hudson River between upper Manhattan and Fort Lee, New Jersey, forming a part of Interstate 95. Opened to traffic in 1931, the George Washington Bridge is the world’s only 14-lane suspension bridge, and the busiest bridge in the world. Under management by the Port Authority of New York and New Jersey, the bridge handles over 90 million vehicles per year.
Transdyn designed, built, and maintains an Intelligent Transportation System (ITS) for the Port Authority of New York &New Jersey. This ITS monitors and controls traffic on the bridge and approach-roads allowing the Port Authority to reduce congestion, improve accident detection and clearance times, and maximize the throughput of the bridge. A series of electronic message signs and other traveler advisory systems provide advance information on travel conditions allowing motorists to choose the most efficient route across the bridge or diversion to other roadways in the event of major traffic congestion.

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 is transforming 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 providing 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. The IPCS constantly monitors the roadway and facilities providing computer managed responses to traffic incidents and other adverse conditions in order to maintain life safety and optimal traffic flow.

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.
The project, which Transdyn designed, is building, and will maintain, is called ATM IDEAS (Advanced Traffic Management Incident Detect/Evaluate/Act System). ATM IDEAS includes designing, furnishing, and integrating new computer, communication, and software systems at each bridge and tunnel control center and the development of a new central Operations Control and Communication Center (OCCC).
The new system will allow the Authority to efficiently monitor traffic, weather, and roadway conditions, detect and respond rapidly to incidents and events, and provide real-time motorist advisories through electronic message signs.
