In accordance with Policy P8, the proposed housing sites at west of Dickens Heath and south of Shirley should not be supported since the impacts of increased delay to vehicles taking account of the residual cumulative transport effects of development are likely to be very severe. A Transport Assessment would be required to accompany planning applications as the proposed housing sites at west of Dickens Heath and south of Shirley would likely have a significant impact on the local highway network. The local highway network leading out from Dickens Heath is already subject to severe congestion in morning peak time.
