Summarization: Mainstream Traffic Flow Control (MTFC), enabled via
variable speed limits, is a control concept for real-time freeway traffic management. The
benefits of MTFC for efficient freeway traffic flow have been demonstrated recently using an
optimal control approach and a feedback control approach. In this paper, both control approaches
are reviewed and applied to a freeway network in a simulation environment. The validated network
model used reflects an actual freeway (a ring-road), fed with actual (measured) demands. The
optimal and feedback control results are discussed, compared and demonstrated to improve
significantly the system performance. In particular, the feedback control scheme is deemed
suitable for immediate practical application as it takes into account operational requirements
and constraints, while its results are shown to be satisfactory. In addition, the control system
performance was not very sensitive to variations of the parameters of the feedback controller.
This result indicates that the burden associated with fine tuning of the controller may be
reduced in the field.
