Background Atkins was commissioned by Southend-on-Sea Borough Council and Essex County Council to develop a comprehensive forecast of travel conditions in Southend and the southern area of Rochford district. The background to this work is proposals to develop land at and surrounding the London Southend Airport (LSA) into new employment provision through a series of business parks. LSA has planning permission to expand its passenger operations up to 2 million passengers per annum (MPPA). The airport began operating regular passenger services in April 2012 with a passenger throughput in 2012 of approximately 0.6 MPPA. It is recognised that this growth in passenger numbers represents a significant opportunity to increase the level of employment locally. Evidence from comparable locations such as Bournemouth, suggest that airports act as hubs for a number of industries which in turn leads to the creation of employment opportunities. In response to this Southend-on-Sea Borough Council (SBC) and Rochford District Council (RDC) have jointly developed the Southend Airport and Environs Joint Area Action Plan (JAAP). The JAAP sets out the proposals for the area and seeks to quantify the opportunities and challenges generated through the proposed employment provision linked to the growth of the airport. This document provides an assessment of the modelling with the objective of providing evidence for the travel conditions in a future year assuming all development is realised. For instance the assessment will determine if increased demand will result in unacceptable levels of highway congestion. The assessment is multi modal and therefore considers highway and public transport provision in a future year through the use of a model designed to consider traveller responses to changes in travel cost. This model is the Southend- on-Sea multi modal model (SoSMMM). SoSMMM is a comprehensive trip forecasting tool developed in line with industry best practice (Department for Transport – Transport Analysis Guidance (WebTAG)). The modelling reflects a 2021 forecast year which was identified as being in line with the predicted planning horizon for the majority of JAAP led developments and the airport reaching its capacity of 2 MPPA. In response to the growth outlined within the JAAP a number of proposed infrastructure improvements have already been identified. The JAAP submission document sets out a number of objectives for transport within the study area: • Ensuring good connectivity to the development area by all modes of transport, with appropriate improvements to sustainable transport and the highway network; and • Minimise traffic impacts and congestion. To achieve the above a number of improvements have been proposed. This includes increasing capacity at individual highway junctions, new bus corridors and a multi modal interchange at the airport to link the railway station, the airport terminal, hotel and employment related to these locations with the wider bus network. The proposals are considered within this assessment in conjunction with the long standing aspiration to reduce congestion and improve reliability along the A127 corridor at recognised bottlenecks.
