The Intelligent Transportation Systems (ITS) program applies new advanced computer and communications technologies to surface transportation systems. Many of the innovative applications planned were unfamiliar to many in the public safety community - most importantly, perhaps, those designed to aid in emergency vehicle response. Also, many of the applications are intended to enhance the safety of the individual traveler, and will be available to both personally owned vehicles as well as vehicles owned and operated by traditional public safety agencies. This creates an environment where spectrum use may be shared between public safety related and non-public safety related functions. Mitretek Systems, under contract to the US Department of Transportation (DOT) Joint Program Office (JPO) for ITS was an active participant in the Federal Communications Commission (FCC) and the National Telecommunications and Information Administration (NTIA) sponsored Public Safety Wireless Advisory Committee (PSWAC). Significant effort was made to determine which of the operational requirements being generated by the ITS program have a significant public safety orientation, what the interoperability requirements with other public safety entities are, and what specific spectrum requirements can be identified at this time. This paper describes the operational, interoperability, and spectrum requirements that were developed by Mitretek and several members of the various PSWAC subcommittees, circulated by the ITS JPO for comment, accepted by the PSWAC and published in their final report. Also described are issues raised by the public safety community concerning technology and interoperability with ITS. |
