Abstract
We present a routing guidance approach that can be used in Automated Highway
Systems (AHS). We consider automated highway systems in which intelligent
vehicles organised in platoons drive to their destination, controlled by a
hierarchical control framework. In this framework there are roadside
controllers that provide speed and lane allocation instructions to the
platoons. These roadside controllers typically manage single stretches of
highways. A collection of highways is then supervised by so-called area
controllers that mainly take care of the route guidance instructions for the
platoons and that also coordinate the various roadside controllers in their
area. In this paper we focus on the optimal route choice control problem for
the area controllers. In general, this problem is a nonlinear integer
optimisation problem with high computational requirements, which makes the
problem intractable in practice. Therefore, we first propose a simplified but
fast simulation model to describe the flows of platoons in the network. Next,
we show that the optimal route choice control problem can be approximated by a
mixed-integer linear problem. Later, we describe a new METANET-like model to
describe the flow of platoons in the AHS. With a simple case study we
illustrate that both approaches result in a balanced trade-off between
optimality and computational efficiency.
