NEW JERSEY (January 13, 2021) HNTB was named as a New Jersey ACEC Honor Award recipient for its role in an ITS project along U.S. 1/Forrestal Road in Plainsboro and South Brunswick Townships.
U.S. 1 in the area is a highly urbanized state arterial with multiple driveways and no access control. During peak travel periods, traffic would bottleneck for two miles where the highway narrows from three to two lanes in each direction. NJDOT realized the use of ITS would increase safety along the corridor and allow NJDOT to effectively monitor and manage traffic operations and provide critical information to motorists.
HNTB was selected as the lead designer for the project, and was involved in the concept development, final design, and construction phases of the project. HNTB’s role involved investigation of existing conditions, feasibility of conceptual design, performance of detailed utility, environmental, right of way investigations and preparation of construction plans. During construction, HNTB was responsible for reviewing and approving shop drawings, addressing contractor queries, and providing design solutions to construction issues encountered.
The design involved the installation of dynamic message system signs and camera surveillance system cameras, plus 14 lane use control signals for a two-mile stretch where hard shoulder running is permitted during peak periods. Design and installation were particularly a challenge because overhead and underground utilities could not be impacted. There were also wetlands within the project limits that needed to be avoided.
“The design for this project was such a success, the NJDOT now considers hard shoulder use, with appropriate ITS, a standard transportation system management and operation strategy when scoping cost-effective congestion management projects across the state,” said Harold Calero, HNTB project manager.
