Knowledge Systems for ITS Standard Deployment – Leads Volume Reduction Necessarily in Loss in Information Content?

The elaboration of standards supported by common European policy is relatively successful, (Summary TC278 2010). It is possible to identify about 180 intelligent transportation system (ITS) standards at present (together with ISO, it is more than 310), some of them are being elaborated, some are under revision and a significant part of standards has been finished. They are focused on the different market applications, starting from CEN/TC278/WG1 “Electronic Fee Collection” (EFC) up to the ISO/TC204/WG16 “Wide Area Communications/Protocols and Interfaces” (CALM) communication standards as examples. There are several basic problems limiting their successful utilization in real praxis. ITS standards are very extensive (in general a standard often has almost 100 pages). Together, there are more or less 17 000 pages of ITS standards, which is a huge quantity for comprehensive reading. The standards are frequently written in the Universal Markup Language (UML) or eXtensible Markup Language (XML) conventions and they need an advanced reader. Additionally, the relations among standards are not simple. Their links are complex and understanding of the entire domain requires study of more than just one standard. Even for experts in ITS standardization it is often difficult to follow such a complex set of standards. The ultimate goal of standards is to be used not only by experts but also among others by investors and decision makers. For people who plan to propose a new public tender based on existing standard is it very hard to find relevant ITS standards at once. The deployment of standards must not be the brake of a successful ITS implementation. This is the reason that “deployment” is very frequent word in ITS standardization process. To facilitate this problem, Williams has published a book “Intelligent transport systems standards”, (Williams 2008). This book has two primary objectives: “to list, summarize, and categorize ITS standards that currently exist, or were under development at the time of the writing”, and to “provide direction and guidance about where to look in the future to find relevant standards for ITS systems”. The book creates relations among different standards and provides short abstract of each of them in a verbal form. Such approach however only lists existing standards and does not take into consideration the fast growth of this field. The aim of this paper is to provide an insight into the complexity of ITS standards and their information content. Two approaches for ITS standard deployment in praxis as adopted in the Czech Republic are presented here briefly. They focus strongly on the reduction of the volume needed to read by general public. This paper provides an analysis of their impact on the information level available. The authors want to demonstrate, that these approaches are able to reduce the volume which has to be read and understood by experts as well as general public, while the information level of information content does not have to be affected significantly. Next to the theoretical foundation, these results are demonstrated on practical experiments carried out within the projects STANDARD and ZNALSYS.
