Roundstone Lane, Angmering

Paul Basham Associates are delighted to see this 700 unit scheme being built out, which required the full range of our transport planning skills to demonstrate the impact on the local and strategic road network could be successfully mitigated.  

The Brief

Originally approached by longstanding client Barratt David Wilson Homes, we were tasked with identifying the total traffic impact of a masterplan covering separate land promotions and planning applications to provide a comprehensive impact assessment of the collective developments, and apportioning the cost of off-site mitigation schemes to each developer.

Our Approach

With the backing of Arun District Council and support from West Sussex County Council (as the highway authority), our team completed an area-wide assessment including junction modelling for up to 720 homes across 11 junctions. This assessment of the impact upon the local road network included local village junctions to major interchanges on the A27 and A259, covering simple T-junctions, roundabouts, signalised roundabouts and signalised junctions.

Where capacity problems were identified, we developed junction solutions to mitigate the development impact and improve local road conditions. Responding to local concerns, a traffic calming scheme was also developed to discourage the use of certain routes through the village, and recommendations made as to the assignment of the associated costs of implementing the off-site schemes under a tariff-based strategy.

Our team also provided input into the design of the Barton Willmore master plan documents, attended open meetings with the Parish Council, members briefings and consultation events to support the clients in realising their vision for the development area as a whole.

The Result

Paul Basham Associates strategic Transport Assessment successfully demonstrated the impact of the housing could be mitigated and the planning applications were subsequently approved. We are very pleased to see the hard work by the project team come to fruition and look forward to seeing the rest of the development built and occupied.
