Project Description:
The Authority’s seven toll facilities - a turnpike, two tunnels and four bridges - provide for the advancement of a safe, secure and convenient movement of people and goods for the benefit of the citizens of Maryland.

Transdyn was selected to design and build a state-of-the-art system capable of managing traffic and facilities for the Baltimore Harbor and Ft. McHenry Tunnels, two of the busiest tunnels in the United States. At the Authority Operations Center, the system will combine the various and differing legacy subsystems at these facilities into a common central platform that provides an integrated operator interface for managing each tunnel. Each facility will be networked to allow inter-site communications, redundant operational capability, and the sharing of data both within the Authority and with other agencies in the area.

The system is managed by Transdyn’s DYNAC ATMSTM (Advanced Traffic Management System) software running on redundant servers and distributed workstations. The ATMS enables the Authority to increase tunnel security and reduce accidents by automatically detecting incidents, mitigating congestion and disseminating motorist advisory messages to travelers.
