System Description: The Integrated Advanced Traffic Management System (ATMS) for Virginia Department of Transportation’s Smart Traffic Center of Hampton Roads, once complete, will manage traffic on 700 lane miles of roadway located in Virginia Beach, Chesapeake, Norfolk, Suffolk, Portsmouth, Newport News, and Hampton.
Transdyn is responsible for the design, development, integration, commissioning, and support of a replacement traffic management system designed to monitor and control intelligent field devices located on the roadways. The new system, managed by Transdyn’s DYNAC® ATMS software, integrates and automates various traffic management functions such as vehicle monitoring, incident detection and management, motorist advisory, and traffic surveillance. The system manages reversible HOV control gates, cameras, variable message signs, and traffic controllers with vehicle detectors. The system also serves state, regional, and local agencies as a data warehouse accessible through the VDOT WAN and the Internet.

System Description: With approximately 150,000 vehicles traveling I-95 and about 75,000 traveling SR 202 per day within the urban Philadelphia area, the Pennsylvania Department of Transportation District 6 is increasing its investment in Advanced Traffic Management Systems (ATMS) in the urban Philadelphia area.
Transdyn has developed, furnished and installed a Traffic and Incident Management System (TIMS) for PennDOT District 6. To date, there are four main ITS components to the system: 1) radar detectors and video analytics that detect vehicle presence, speed, occupancy and volume in the roadway, 2) the CCTV subsystem that allows operators to verify incidents and determine the appropriate response plan through direct observation, 3) the communication system consisting of a fiber optic backbone, T1 digital telephone lines for compressed video signal transmission; DS-0 telephone lines for detector transmission; and voice grade telephone connections for Dynamic Message Sign (DMS) control, and 4) the central computer hardware and incident detection software that processes the raw data and integrates control of the cameras and DMS. All central system components communicate via an Ethernet LAN.

System Description: CityLink (www.citylink.com.au) is a 22-kilometer automated tollway in Melbourne, Australia that connects the Tullamarine Freeway, the West Gate Freeway, and the Monash Freeway. The toll road provides reduced travel time between the Central Business District and Melbourne's suburbs, the airport, and Australia's largest seaport.
The new computer system, running Transdyn's DYNAC� Enterprise Server software suite, will provide seamless management of all aspects of traffic and plant operations. From a unified operator interface, the new system will monitor and control the roadway's video cameras, vehicle detectors, electronic message signs, weigh-in-motion and counting stations, emergency telephones, motorist advisory radios, ventilation, lighting, electrical distribution, access control, fire detection, and environmental systems. DYNAC�'s highly integrated user environment and advanced incident response management application will allow CML to safely and efficiently manage both traffic and facilities operations especially during emergency situations.
