    Today, there are many choices to search for information for both daily commuting and longer trips. However, it has been found in earlier studies that users do not always find the information they would like to get. This may be due to fact that users do not know the existing information sources, or they find them too complicated and time consuming to use. One way to help users out of the situation is to collect the existing traffic and travelling related information into one portal – for instance into the same Internet-page. In US, the three digit number 511 has been selected as a common brand for traffic and travelling related information. At the moment, the service is available in 23 states and is to be expanded to cover 75% of the population by the end of 2007. In most of the states, 511 is a service available both by phone and in the Internet. There are similar plans for gathering together different pieces of traffic information in EU countries. In addition to the challenges faced already in US, there will be additional ones in case of many countries and languages involved, as the case is in Europe. Therefore, it is crucial to understand needs of drivers and travellers around the continent to facilitate the development of traffic and traveller information services.
