Executive Summary 1.1 The Havant Borough Local Plan sets out a vision and a framework for the future development, growth and prosperity of the Borough. The Local Plan process commenced with the adoption of the draft Local Plan Housing Statement, in December 2016. Further evidence has been obtained and consultation undertaken to prepare the Local Plan. The Local Plan aims to deliver about 9,550 new homes, and 95,000 sqm of new employment floor space in the Borough, by 2036, including development on Hayling Island. 1.2 Crucial to ensuring that the Local Plan’s proposals constitute sustainable development, is the timely provision of infrastructure, to support the amount of development proposed in various locations across the Borough. Part of the Local Plan evidence base is provided by the Mainland Transport Assessment and Hayling Island Transport Assessment. They both review the existing traffic and transport networks, examine future demand and identify required mitigation and improvements to accommodate development. 1.3 The Hayling Island Transport Assessment has been prepared by Havant Borough Council with transport planning support from Campbell Reith and traffic modelling from Systra. This report sets out the findings of the Hayling Island Transport Assessment and explains the methodology underpinning the results. 1.4 A microsimulation model, in Paramics, has been built to assist in assessing the impact of the future development on the road and transport network on Hayling Island and any required infrastructure improvements to support and provide an evidence base for the Local Plan. 1.5 A baseline reference case, including background traffic growth and future year models, with and without mitigation measures, were developed to test the impact of committed and Local Plan development. 1.6 Results from the ‘Do Minimum’ (Local Plan Development without mitigation) outputs demonstrate that traffic flows, traffic queues and journey times on Hayling island all increase, as a result of additional future development. Model outputs for the ‘Do Something’ scenarios (with mitigation proposals) show that improvements in journey times and reliability can be achieved, however, in some locations, measures such as traffic signals increase queue lengths and journey times. In general, where queue lengths and journey times have increased, this has been redistributed from other arms at a junction, thereby, reducing delay overall. 1.7 Taking into account the wider benefits associated with
