One of CTC's areas of concentration is Intelligent Transportation Services (ITS). CTC assists state and local governments with the communications aspects of developing ITS networks and integrating such networks into broader telecommunications strategies. CTC assists with evaluation, planning, design, and implementation of traffic information radio and roadway surveillance systems. We specialize in providing technical support to state and local governments in identifying and implementing nontraditional and emerging ITS strategies (such as use of the Internet, state-wide radio, and/or cable television for dissemination of traffic information).

Delaware Department of Transportation (DelDOT): CTC is the primary communications network designer for the DelDOT system, which is comprehensively addressing multi-modal transportation over the entire state. Once the network is complete, thousands of controllers and ITS sensors and hundreds of monitor devices, including video feeds, will enable the control, monitoring, and dissemination of ITS data. The telecommunications backbone infrastructure will be composed of hundreds of miles of fiber optic cable along with microwave and radio connectivity. Significant components of this system are online currently, and additional components will be coming online in the next six months.

The DelDOT ITS project has several telecommunications-related components that make it unique, among them:

The size of the project, which will link transportation systems across the state through a state-wide communications network;

The scope of the project, which will link bus, ferry, rail, roadway, and other forms of transportation, thus supporting data connectivity across a diverse set of users and data sources;

The large number of video sources proposed (over 200);

The video sources will support high quality full motion video, making the video available to Internet users as well as cable and broadcast TV outlets for dissemination;

A revolutionary strategy to replace low-coverage Traveler Advisory Radio Services (TARS) with a state-wide radio signal that will provide round-the-clock coverage of traffic conditions.

Strong adherence to existing and emerging standards, including NTCIP and commercial network and communications standards, in an attempt to ensure compatibility and expandability.

Montgomery County, MD: CTC developed a County-wide telecommunications system for gathering and disseminating transportation information using a fiber optic based network. The system supports the distribution of audio messages, graphic messages, and live traffic status reports using a closed circuit video surveillance system. The fiber optic network is an integral part of the development of Montgomery County's Advanced Transportation Management System (ATMS). The ATMS continues to serve as a foundation for future automated highway and transit systems in the County, and is part of the Federal Government's Intelligent Transportation Systems (ITS) program.

The fiber optic-based network provides access to all County traffic signal controllers and supports a traffic surveillance system consisting of over 200 camera sites. All sites can be controlled from a central Traffic Management Center. CTC assisted with the design and engineering of the network, preparing specifications for the equipment and management systems comprising the network, and providing oversight supervision for the construction, implementation and maintenance of the network.

Maryland State Highway Administration: CTC assisted in the design and implementation of traffic information radio systems. These systems operate in the AM frequency broadcast band and provide coverage over a thirty square mile area. CTC has worked with MSHA to develop a wide area of coverage using multiple radio sites synchronously interconnected by broadband communications systems. CTC has performed engineering studies for radio frequency allocation, designed interconnection systems, and equipped studios for production and distribution of traffic advisory announcements.

Baltimore: CTC worked with the City to plan, design, engineer, and implement a closed circuit traffic surveillance and control system for heavily congested areas such as the Inner-Harbor, major highway corridors, and Oriole Park at Camden Yards. CTC was responsible for overall system design, and wrote specifications for individual components. CTC also assisted the City with the installation and activation of the system. The initial project included a twelve-camera system, with plans for a future system comprised of over 100 cameras controlled and monitored from a single operations control center.

CTC worked with Sabra, Wang and Associates to develop a conceptual design for an upgraded traffic signal system. CTC performed tests on the City's existing twisted copper pair cable plant to evaluate the condition of the cable and determine whether it would be able to support communications for the new signal system. CTC also provided an analysis of the various communications alternatives that are currently available, and made recommendations for use of technologies that would best meet the City's needs and budget constraints.

Cincinnati: CTC planned, coordinated, designed, and engineered a traffic surveillance system at key intersections throughout Cincinnati for the City's Department of Transportation. The project is a cooperative venture between the City and the local cable company. The transmission medium consists of coaxial cable, fiber optics, and microwave paths. The initial demonstration project included three camera sites, but the system design is capable of supporting a network of more than 100 cameras.
