DEA Selected for Route 9A Construction Management  

NYSDOT recently selected the Joint Venture of STV / URS with DEA as subconsultant, to provide construction management, project administration, project controls and project coordination for the Route 9A Lower Manhattan Reconstruction Program. DEA’s activities will focus on ITS and operations.   

The project will consist of three or more large, complex construction contracts for the reconstruction of Route 9A within the corridor from W. 59th Street to the FDR Drive at Catherine Street.  These contracts will include major highway reconstruction, complex utility relocations, ITS, security systems, extensive MP&T, coordinated construction scheduling and staging (with other agencies / entities doing construction in Lower Manhattan), monitoring of contract environmental protection measures, and a number of other complex features. In addition, the construction projects may also include an 1100 to 1500 ft. cut and cover tunnel (within the area from Vesey St. to Albany St.), and a large pedestrian concourse tunnel structure located transverse to and below the Route 9A tunnel between the World Financial Center and World Trade Center.  

As described in the report, Redevelopment Alternatives, NYSDOT has identified 4 basic Route 9A options: 1) at grade reconstruction, 2) lowered roadway with a 450 foot wide pedestrian deck, 3) short (1100 ft.) bypass tunnel, and 4) long (3400 ft) bypass tunnel. In the preparation of the DSEIS, alternatives have been narrowed down to: 1) no action, 2) at grade and 3) short bypass.

DEA / PB Joint Venture Selected for Westchester ATMS Design  

NYSDOT recently selected the joint venture of DEA and Parsons Brinckerhoff to provide scoping, preliminary and final design services for the installation of communications systems, and Advanced Traveler Information Systems (ATIS) in Westchester County, New York.  Corridors include:  

o       The Hutchinson River Parkway

o       The Cross County Parkway

o       The Saw Mill River Parkway    

o       The Sprain Brook Parkway

These roadways form an interconnected network of heavily traveled corridors in the critical southern portion of New York State Department of Transportation Region 8. Commuter flows are heaviest during morning and evening peak periods, and the ATIS will help by monitoring the highway and allowing observation of the highway.  The communications system will allow collected data to be brought to the Transportation Management Center where the Department will communicate incident information to travelers, aiding in the flow of travel in the Region. The project objectives are to deploy necessary roadway devices (detection, CCTV, variable message signs, fiber communications equipment and the like) for data collection and dissemination.  

The design will cover installation of communications, intelligent transportation systems and equipment on approximately 70 miles of highway in NYSDOT Region 8 including major feeder routes.   

Project outputs include an Expanded Project Proposal (EPP), a Design Report, and individual PS&E packages, one for each of the above corridors.  Contents will specify the nature, size and position of ATIS equipment, fiber optic cables, and other required communications hardware, firmware and software.  

Subconsultants on the team include Dewkett Engineering, P.C., Amy S. Greene Environmental Consultants, Inc., and S. Y. Kim Land Surveyor, P.C.  

Construction cost is estimated at $ 50.0 M.

Macomb County Award to DEA

The team of Hubbell, Roth & Clark and DEA was selected to design an Advanced Traffic Management System for Macomb County, Michigan.  Macomb County is a rapidly growing area northeast of Detroit with a quarter million population.   The Road Commission of Macomb County (RCMC) constructs, operates and maintains 2,942 lane miles of county, primary and local roads as well as 756 bridges and drain structures.  It also maintains more than 1,500 miles of road with more than 800 traffic signals and 60,000 signs.  

Contract workscope includes preparation of a Concept of Operations, an ITS Master Plan and a Communication Plan.  Preliminary and final design of a Traffic Operations Center is also included.

Eastern Queens ATMS Design Awarded to DEA

DEA has been awarded a contract to provide engineering services to NYSDOT for the implementation of an Advanced Traffic Management System (ATMS) for highways in Queens County, New York City. The Services to be provided include Expanded Project Proposal (EPP) development, Preliminary Design and PS&E development.

The ATMS will be capable of surveillance, full-scale incident management, route diversion, traveler information and traffic management.

The Eastern Queens sub-regional ATMS is a critical part of the overall regional ATMS operation, since it integrates the operation of all roadway networks in Brooklyn, Bronx, Queens and Long Island.


Operate the Interim Operations Center (IOC)                               for Boston Central Artery / Tunnel (CA/T)

The Massachusetts Turnpike Authority recently awarded DEA a contract to Operate the Interim Operations Center (IOC) for the Boston Central Artery / Tunnel (CA/T) Project.

The IOC is a 24/7 communications facility that supports CA/T Project construction and mitigation efforts. The IOC manages the Project Emergency notification system, and maintains continuous monitoring
and contact with public emergency services.


PB / DEA Designated to Operate JTOC


New York State DOT recently announced that the team of Parsons Brinckerhoff and Dunn Engineering Associates (along with Eng Wong Taub & Associates and the Sam Schwartz Company) was designated to operate the Joint Traffic Operations Center in Long Island City. The PB / DEA team  took over operations in January, 2004.

JTOC currently controls or will control the 5 Advanced Traffic Management Systems (ATMS) of Northern Manhattan / Bronx; Western Queens; Eastern Queens; Brooklyn; and Staten Island.
It is planned to expand the current center to accommodate these systems, currently scheduled to be completed by 2006. This new facility will be known as the JTMC or Joint Traffic Management Center.


Managing Travel for Planned Special Events 

The Federal Highway Administration awarded a contract to DEA and Iteris Corporation, to develop National Highway Institute Course No. 133099, Managing Travel for Planned Special Events. This course will provide practitioners with a working knowledge of techniques and strategies to successfully: (1) plan for and operate a particular planned special event or (2) manage all planned special events in a region. Practitioners will gain an understanding of the collective tasks facing multidisciplinary and inter-jurisdictional planned special event stakeholder groups charged with developing and implementing solutions to acute and system-wide impacts on travel during a special event.

Course sessions will identify potential tasks and stakeholder activities conducted within individual planned special event management phases. The course will promote the Managing Travel for Planned Special Events handbook prepared by DEA and guide participants on how to apply its key concepts. The Managing Travel for Planned Special
handbook can be accessed via the following link:



Technical Guidance on Alternate Route Plans                           and Plan Development

DEA, working in association with SAIC, received a task order  Development of Technical Guidance on Alternate Route Plans and Plan Development. The objective is to identify both the recommended process and contents for an alternate route plan and its constituent routes. DEA will lead a group of consultants, including TransCore, Street Smarts, The Louis Berger Group, and Woodward Communications, in the preparation of a comprehensive technical reference that details a standard procedure for developing
alternate route plans and the routes they contain.

The forthcoming technical reference will identify and recommend successful policies, guidelines, and procedures for use in alternate route selection and plan development. This includes summarizing criteria for deployment of alternate route plans under specific situations and resources used in plan deployment and diversion route operation. The technical reference will distinguish between the needs and requirements of regional and local jurisdictions encompassing a range of area types, including rural, urban, and metropolitan.
