New information and communications technologies (NICTs) provide new possibilities for improving user information provision; however, we must not forget those who are not familiar with these new technologies, or who do not have access to them: even the most comprehensive and efficient website, accessible via mobile phones and interactive terminals in transport interchanges, can never replace paper network maps and timetables, quite simply because there will always be users who prefer these forms of information. Of course, this should not in any way impede the development of new means of communication, particularly those capable of calculating optimum routes within complex networks, or which enable users to find out, via their mobile phone, when the next bus will arrive at a particular stop. The biggest challenge ahead lies in providing users with information that is both comprehensive and easy to understand, concerning the whole of their journey, even if this involves more than one transport network, with more than one managing authority and more than one operator. This challenge is more complex to resolve than it may first appear, as it requires dialogue and cooperation between different organisations with sometimes very different interests and priorities, on scales that are sometimes incompatible, and, above all, regarding data that must first be standardised before it can be compiled, processed and distributed. Furthermore, this is something of a never-ending task, as networks are constantly changing (timetable changes, new routes and lines, changes in fares, etc.) – however, this is the price that must be paid for high-quality information.
