We have global time, belonging to the multimedia, to cyberspace, increasingly dominating the local time-frame of our cities, our neighborhoods. Nothing is ever obtained without a loss of something else. What will be gained from electronic information and electronic communication will necessarily result in a loss somewhere else. If we are not aware of this loss, and do not account for it, our gain will be of no value. This is the lesson to be had from the previous development of transport technologies. The realization of high velocity railway service has been possible only because engineers of the 19th century had invented the block system, that is a method to regulate traffic so that trains are speeded up without risk of railway catastrophes. But so far, traffic control engineering on the information (super)highways is conspicuous by its absence.
