This paper begins with a description of current usage of variable message signs for traffic management in Amsterdam. The authors then focus on the standardization efforts that led to standardized functional and technical specifications for dynamic signs, a Central Dynamic Route Information Panels (DRIP) Management system, and the development of a communication protocol. The paper concludes with a discussion of recent developments, and the strengths and weaknesses of graphical information.
