Some aspects of the stability of traffic flow. Paper prepared for the 4th International Symposium on the Theory of Traffic Flow, Karlsruhe, June 1968.

The theoretical development of a criterion for the stability of traffic flow is in agreement with the findings derived from aerial surveys of traffic flow. Both academically and from a practical point of view this approach opens avenues for a better understanding of the stability of traffic flow and the determination of control parameters to ensure stable traffic flow.
