摘要

The purpose of the Polaris Project is to define an Intelligent Transportation211u001eSystems (ITS) architecture for the state of Minnesota. An architecture is a 211u001eframework that defines a complex system, in terms of a set of smaller, more 211u001emanageable systems which are fully defined in terms of their individual 211u001eboundaries, functions, physical components, and interfaces.They illustrate how 211u001eeach of the systems interrelate and contribute to the overall ITS objectives and 211u001erequirements. A well defined architecture provides many benefits for a complex 211u001esystem. It defines and optimizes the location of system functions.It identifies 211u001ecritical interfaces, and illustrates how associated systems can be integrated to 211u001eshare resources and information. It establishes standards for communications and 211u001ephysical components so that interoperability can be maintained as the system 211u001eevolves to incorporate new capabilities and technologies.
