ITS Cabinet (ATC 5301 V02)

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 joint development of the Advanced Transportation Controller (ATC) suite of standards for the ITS community. These three Standard Development Organizations (SDOs) have agreed that the development of these standards will assist state and local governments in the deployment of ITS technology in both urban and rural environments.

The ATC suite of standards provides an open architecture hardware and software platform which can support a 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 suite of standards includes the following:

• The Advanced Transportation Controller (ATC) ATC 5201Standard; (The “brains” or the field computer which manages the cabinet functions)
• ITS Standard Specification for Roadside Cabinets (This includes various constructs (e.g. input files) and subassemblies/subsystems to support the control and monitoring of field devices at the intersection/highway location)
• ATC Application Programming Interface (API) ATC 5401 Standard (This creates a software suite to allow the sharing of the input-output and other controller resources for multiple applications at the street/field location)
• ATC Application Programming Interface Reference Implementation (APIRI) which is software representative of the ATC 5401 standard.

For each application that the ATC serves, the cabinet and cabinet subsystems may be selected from a set of standard parts and subassemblies defined in the ITS Roadside Cabinets standard. The ITS Roadside Cabinet development committee initially targeted more traditional traffic control applications such as traffic signal control, ramp control, traffic surveillance stations, lane use signals, field masters, and lane control. As a result, the modular structure of the cabinet focused 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 for traffic control cabinets. In addition, the serial control and monitoring bus arrangement (similar to the NEMA TS2-2003 Type 1 cabinet) is modular in nature and supports the development of additional special function-oriented assemblies for ITS functions of the future.

Comments on the standard are welcomed at any time and are collected using the comment form and email it to Standards@ite.org. However, when the project/working group is active, then actions will be taken on comments received.

Other standards within the ATC program include the Model 2070 Standard, the ATC API, and the ATC Controller.
