**Abstract:**

This paper proposes an efficient model predictive control strategy
that is based on the parameterization of a variable speed limit
control scheme. Due to the parameterization, the solution spaces
reduces, which leads to an improved computation time. The
parameterized control scheme consists of a speed-limited area in which
a constant speed limit is imposed. By changing the position of the
head and tail of this speed-limited area over time it is possible to
change the density and flow in and downstream of this area. The
controller optimizes the location of the head and tail of this area
over time in such a way that the flow into a bottleneck or jam wave is
changed such that congestion can be prevented or resolved. An
advantage of this approach is that the complexity of the optimization
problem does not increase with an increase in the number of variable
speed limit gantries. The controller is tested using a second-order
macroscopic traffic flow model. It is shown that the controller
improves the total time spent by all the vehicles in the network with
3.7% compared to the no-control situation. This improvement is
realized by resolving a jam wave. It is also shown that the controller
can achieve a better performance than other model predictive control
strategies, when using the same amount of computation time.
