INTRODUCTION 1.1. Moto Hospitality Ltd intends submitting a planning application for a Motorway Service Area (MSA) on land adjacent to Junction 6 of the M3 Motorway at Basingstoke. Moto is the leading provider of services on the UK’s motorway network with sites in England, Scotland and Wales, with MSAs across 45 locations. Moto proposes to expand its service offer at locations where there are gaps in the strategic highway network to meet the safety and welfare needs of the travelling public. 1.2. The proposed development will comprise: a direct access off the M3 Junction 6 roundabout, which will be modified to accommodate an additional arm; an amenities building incorporating a food court, toilets and related facilities; a ‘drive thru’ unit (coffee); a fuel filling station with separate areas for light vehicles and heavy goods vehicles; electricity charging points; parking spaces for various categories of vehicles; and a lodge-style hotel with 100 bedrooms. 1.3. The scale of development is one that requires a Transport Assessment1. The Transport Assessment (TA) examines the transport impact of the development proposal and proposes mitigation measures where appropriate. It has been prepared in accordance with the National Planning Policy Framework, the section of the Planning Practice Guidance dealing with ‘Travel plans, transport assessments and statements in decision- making’ published in March 2014, the Department for Transport’s (DfT) Circular 02/2013 ‘The Strategic Road Network and the Delivery of Sustainable Development’ published in September 2013 and is in line with ’The Strategic Road Network: Planning for the future’ published by Highways England in September 2015. 1.4. This TA comprises the following sections: Introduction Planning Policy Existing Conditions Need for a Motorway Service Area Proposed Development Transport Accessibility and Sustainability Trip Generation and Distribution Future Year Assessment Impact on the Transport Network Construction Traffic Mitigation Measures Concluding Comments 1.5. It has been prepared to satisfy the requirements of the National Planning Policy Framework, to inform the assessment of
