1.1 ,This guide covers desired approaches to be considered and followed in planning, developing, and operating specific ADMS for the archiving and retrieval of Intelligent Transportation Systems-generated data. The scope of this guide anticipates incremental or modular implementation of an ADMS, which over time and with a series of investment of resources will approach or exceed desired practice. However, it is recognized that programmatic constraints of time and budget resources do not always allow practitioners to follow a more desirable course of action, and that during interim periods the ability to implement a particular fully functioning system may be less than desired.
