Advanced Transportation Controller (ATC)


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 for the ITS community. The Advance Transportation Controller (ATC) Standards was 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 joint efforts of AASHTO, ITE and NEMA have provided input and gained support from all levels of government, academia, consultants and industry personnel in the development of these standards. Continued support from the ITS Joint Program Office (JPO) is necessary for the successful completion of this task and the continued deployment of the ATC.

AASHTO, ITE and NEMA believe that ATC standards will contribute as much or more to ITS deployment than many other ITS standards being supported by the JPO. Because of the high priority that has been assigned to the ATC standards for ITS deployment, it is important to gain widespread acceptance of these standards.

New!
Advanced Transportation Controller (ATC) Application Programming Interface (API) Standard v02.06b is now an approved ITE, AASHTO and NEMA approved Standard available as a free download.

The ATC Controller Standard defines a Front Panel interface for Operational Users to interact with the application programs that are the primary tasks of the controller unit within the transportation system. When combined with the ATC operating system, the API forms an open architecture software (SW) platform that acts as a universal interface between application programs and the ATC controller units.

The API manages the resources of the ATC controller unit which are intended to be shared between concurrently operating application programs and whose functionality is not inherently supported in Linux (or by the device drivers created for the ATC). These managed resources include the Front Panel and the Field I/O Devices. The API does not communicate directly to these ATC resources but through the Linux operating system and associated device drivers provided with the ATC controller unit.


ITE’s Notice of Intent to Adopt ATC API V2.06a

The final draft version of the Advanced Transportation Controller (ATC) Application Programming Interface (API) Standard v02.06a has been approved by the ATC Joint Committee of ITE, AASHTO and NEMA. The Institute of Transportation Engineers (ITE) intends to adopt this standard as of September 10, 2007 assuming no final appeals are received. Please check the ITE website (www.ite.org) for a notice after September 8, 2007 as to whether this version has been adopted by ITE. When adopted this standard will be jointly published by ITE, NEMA and AASHTO.

The following documents are offered in support of the Notice.

Notice of Intent to Adopt ATC Controller Standard Revision 5.2a  Word  |  PDF

The final draft version of the Advanced Transportation Controller Standards, ATC Controller Standard Revision 5.2a, has been approved by the joint ITE, AASHTO and NEMA Committee on the ATC. The Institute of Transportation Engineers (ITE) intends to adopt this standard as of April 6, 2006 assuming no final appeals are received. Please check the ITE website (www.ite.orq) for a notice after April 6, 2006 as to whether this version has been adopted by ITE. When adopted this standard will be jointly published by ITE, NEMA and AASHTO. [Note that per the terms of the memorandum of understanding between ITE, NEMA, and AASHTO, all three organizations must approve this document for it to become a standard, hence, any reference to this document as a standard prior joint approval through the formal balloting process of each organization, is inaccurate.]

The Advanced Transportation Controller (ATC) is being developed to provide an open architecture hardware and software platform for a wide variety of ITS applications. In this context, the words "open architecture" mean that the system can support both public and private sector developers, and have modular software cooperatively running on standardized and shared modular hardware platforms. This will provide cost-effective ITS functionality for a wide variety of applications. To accomplish this goal the system needs to provide the maximum flexibility for many different system configurations and installations.
