ABSTRACT
Information technologies are aiding the growth of new and more rational road transport systems. At the core of Intelligent Transport Systems (ITS), traffic management and control critically depend on technical devices and road information well suited for road users because, in the end, the information in front of road users (e.g., VMS) is the basic tool for improving road traffic. In addition to a necessary technological optimism, a critical view is necessary for lessening or avoiding pitfalls. New presentation systems may distort the road sign system and worsen communication to road users.
