NOTE: User services as defined by the National ITS Program Plan, ITS America, March 1995.

Like standards development, many other aspects of ITS development and deployment will involve new and complex coordination issues. The technologies for many ITS applications have already been developed, but a variety of nontechnical issues will determine how and when these applications become widely available. Liability, intellectual property, security, privacy, and data ownership issues will all influence the commitment of private firms to deploying ITS services and the interest of users in adopting them.

Those in government and in industry responsible for planning and coordinating ITS developments recognize that some of the communications systems, such as those supporting traffic flow control and addressing emergency situations, will require real-time, quick response capability with high reliability. Such systems will probably have to be dedicated to ITS applications. At the other extreme, trip planning and many other offline applications can surely be supported by the nation's general purpose data networks—the NII. It is unclear, however, where the boundaries lie and what combination of architecture, commercial strategies, public services, and regulatory constraints will serve to define this relationship. In short, is the ITS a domain-specific application of the NII? Or is ITS a special environment whose information systems support is specialized and only loosely coupled, through data sharing, with the NII?

Intelligent Transportation Systems

The mission of the ITS program is to improve the safety, efficiency, and capacity of the country's surface transportation system through the use of information technology. The ITS program is coordinated within DOT,
