Intelligent Transport System Architecture Different Approaches and Future Trends

摘要

System Architecture for Intelligent Transport Systems (ITS) has been an active topic across the globe for many years. There are two basic different approaches to its creation and implementation, represented by the European ITS Framework Architecture, called FRAME, and the National ITS Architecture of the USA. Their principal differences lie in the manner and the flexibility of their use. The challenge Europe is facing is based upon the fact that there are many different states with different needs and it is therefore not possible to create a universal ITS architecture suitable for all of them. For this reason, there is framework architecture at the European level from which national or regional architectures can be created by specific states based on their individual requirements. Thus, the situation varies from state to state. On the other hand, the USA has a fixed ITS architecture, the use of which is obligatory if federal financial support for ITS deployment is desired. This paper aims to compare the two approaches and discusses the developments and ongoing activities to support ITS architecture implementation in Europe.
