Samenvatting
This article describes the structure and the use of the traffic control-simulation package FLEXSYT. This is a acronym of FLEXible-network-Simulation-studY-TOOl. The results show that the principles of the program can be used for research into different intersection and traffic network systems. An example is given. Because of the techniques used the limits of computer time and computer memory have not yet been reached. Model validation is started.
