Minnerva assisted Peter Brett Associates in building
a highway model to test several re-alignment options for the Route
de la Liberation along the Waterfront area of St Helier, as part
of a planned redevelopment of the area.
Having evaluated the primary alignment options,
the model was used to test the implementation phasing for the preferred
scheme, given that the Route de la Liberation acts as an important
primary route in and through St Helier.
A feature of the analysis was the construction
of a Dynamic Highway Assignment model which provided a detailed
understanding of traffic behaviour within what is a small, but dense
The dynamic assignment model identified key junctions in the network
with the formation of queues blocking back along approach links
and subsequent interactions taking place. This provided greater
insight into the network's performance than was releaveled by conventional
'static' assignment without the need to develop a separate micro-simulation
