Project Description:
The Trans-Koolau tunnel complex on the H-3 highway provides a third connection between the Honolulu metropolitan area and the northeast side of the Island of Oahu. This state-of-the-art highway system has a sophisticated traffic surveillance and control system to manage traffic incidents and provide real-time traffic information to motorists.
Managed by Transdyn’s DYNAC ATMS software running on redundant servers, the system provides a unified interface for monitoring and controlling the facility, detects incidents, enables operators to increase life safety, and reduces congestion. The system also monitors traffic and tunnel conditions and can automatically change the traffic configuration (e.g. close one tunnel bore). Traffic and tunnel information is then disseminated to travelers via DMS and motorist advisory radio.
