4.5.1 Anticipated Requirements of an Archived Data User Service

In April 1998, the body responsible for defining ITS User Services took the step to initiate an ADUS. That process is likely to be completed while CHART II is being implemented. A report released by U.S. DOT in April 1998, called ITS as a Data Resource: Preliminary Requirements for a User Service, identifies a set of system requirements as well as a set of implementation issues. The following is a paraphrasing of 16 guiding principles presented in Chapter 4, Basic Requirements, of that report. These principles should serve as the basis for developing a more detailed set of requirements for consistency with the National ITS Architecture.
