The first of all is a “non-specialist” who needs the appropriate guidance through the web page (through the ITS world). This option considers much more explanatory and contextual work then it could have been done and it was left apart for future contributions.

The second and third types (2A and 2B) have been put together as they have the same point of view – manufacturer/ test laboratory and contractor/supplier have been covered by one classification “expert”. The category “expert” represents a user who is already familiar with technical content of ITS world and makes a profit of keywords that lead him towards relevant standards immediately. The keyword can be entered or chosen from the list which is provided. The list contains about 90 keywords. Every single standard is defined at least by one keyword. Several keywords can be used at once to specify the subject of search. The illustration below shows one possibility to get the right keyword supported by “completion insight” giving also the resulting number of standards belonging to that particular keyword.

The fourth category is the “investor/ITS system owner” who is to put up a tender. The investor can use the classification of possible standardized ITS application, e.g. EFC. Each application is then subdivided into more specific fields of interest – e.g. microwave EFC, satellite EFC, payment by card, EFC security protection etc. The classification was done at the time of the project and does not involve the latest development.
