Further, ITS is a developing sector, and standards are being developed as the technology evolves. Indeed, the technology can only evolve to its potential if the technical developments are undertaken cooperatively, often in pre-competitive phases, and the development of Standards is an intrinsic part of this process...
In addition to the analysis of services into "Service Domains", as analyzed in ISO 14813-1, we also have other "views" that we need to consider if we are to understand ITS. Each of these views considers an aspect of ITS that can be used by interested parties to group some of the services in different ways. These are complementary, not competitive means of analysis, and when considering Standards that support ITS can provide a very useful "view".
