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 road network.

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 model.
