The American Association of State Highway and Transportation Officials (AASHTO), the Institute of Transportation Engineers (ITE) and the National Electrical Manufacturers Association (NEMA) have executed a Memorandum of Understanding (MOU) for the development of the Advanced Transportation Controller (ATC) Standards suite for the ITS community. The Advance Transportation Controller (ATC) Standards were rated as one of the highest priority ITS standards for development in a survey conducted by ITS America and FHWA. The three Standard Development Organizations agree that the development of these standards will assist state and local governments in the early deployment of ITS technology in both urban and rural environments.
The Advanced Transportation Controller was developed to provide an open architecture hardware and software platform for a wide variety of ITS applications. This means that the system can support both public and private sector developers and have modular software cooperatively running on standardized and shared modular hardware platforms. The ATC will provide cost-effective ITS functionality for a wide variety of applications. The ATC standards suite provides users with a standardized method for interacting with controller unit programs within the transportation system. The standards will ensure better interoperability between programs that share the same resources but are supported by different operating systems.
The standards included in the ATC Standards suite are:
For each application that the ATC serves, the cabinet and included subsystems may be selected from a set of standard parts and assemblies defined in the ITS Roadside Cabinets standard. The ITS Roadside Cabinet development committee has focused initially on the more traditional traffic control applications: traffic signal control, ramp control, traffic surveillance, lane use signals, field masters, lane control, and access control.
As a result, the modular structure of the cabinet focuses on providing rack space, power management, and serial buses for the classic traffic control input devices, load switching, and cabinet monitoring to ensure that the ITS cabinet is consistent with past practices. In addition, the serial control and monitoring bus arrangement is modular in nature and supports the development of additional special function oriented assemblies to support some of the ITS functions of the future.
Other standards within the ATC program include the Model 2070 Standard, the ATC API, and the ATC Controller.
