The Hawaiian Department of Transportation (HDOT) recently awarded Transdyn a contract to upgrade the DYNAC operations management control system used to manage facilities and traffic inside the Tetsuo Harano tunnel and on the Halawa and Haiku viaduct tunnel approaches along Oahu’s H-3 freeway. The upgraded system will allow HDOT to take advantage of the latest advanced traffic management system (ATMS) technologies and maximize system performance needed to efficiently reduce congestion and improve motorist safety.
Transdyn is providing DYNAC ES ATMS software, configuration, interfaces to legacy field equipment, additional reporting capabilities, testing, training, start-up services, and documentation.
DYNAC is a high-performance, integrated software suite, built with the latest open-architecture. The software combines all the features of an advanced transportation management and SCADA system to deliver the performance and reliability needed to effectively monitor, manage and secure major infrastructure facilities.
The DYNAC system provides a unified interface for monitoring and controlling the tunnel and highway facilities. These functions include incident detection and management, tunnel and facilities life safety systems monitoring, closed circuit television (CCTV), control and automatic traffic configuration adjustment such as closing a tunnel lane or an entire bore. Traffic and tunnel information is then disseminated to travelers via dynamic message signs (DMS) and motorist advisory radio.
HDOT is responsible for planning, designing, constructing, operating, and maintaining state facilities in all modes of transportation, including airports, harbors, and highways. The mission of the highways division is to provide a safe, and efficient and accessible highway system through the utilization of available resources in the maintenance, enhancement and support of land transportation facilities.
