This study sought to identify existing problems or opportunities for improvement. The study has considered the safety and operational aspects of the corridor and the junctions, looking into the impact of existing and proposed traffic growth in the wider area as well as considering the strategic role the A9 plays for connectivity to the north of Scotland. The study has reviewed both current and future operations, taking account of potential and future developments within the surrounding area, and has been undertaken in line with Scottish Transport Appraisal Guidance (STAG). The study represents the Initial Appraisal (Case for Change) stage of the STAG process (formerly known as the Pre-Appraisal stage) and sets out whether there is a case for change. SCOPE OF THE STUDY The study area includes both carriageways of the A9 from North Kessock Junction to Tore Roundabout and all junctions in between. The objectives of the study are to: ¡ Develop and evidence the problems, opportunities and transport planning objectives in the form of a STAG Initial Appraisal: Case for Change Report; and ¡ Undertake effective stakeholder engagement that enables appropriate local representation to inform the evidence base for the appraisal. Following completion of this Initial Appraisal: Case for Change stage, if Transport Scotland considers that there is a case for change, and there is funding available to do so, the study will continue into the Preliminary Appraisal stage. KEY FINDINGS FROM THE STUDY Traffic and Road Safety Analysis The analysis of the traffic and road safety evidence identified the following: ¡ Traffic levels during the study period September 2020 are within 10% of those observed in September 2019 (pre-COVID). ¡ The traffic growth projected for the A9 between 2020 and 2035 is 9.79% between North Kessock and Tore Roundabout based on modelling informed by the adopted Inner Moray Firth Local Development Plan (2015). ¡ The collisions statistics show that collisions are spread out over the extent of the study area and do not exhibit any common contributory factors. A9 NORTH KESSOCK TO TORE STUDY PUBLIC | WSP Project No.: 70075948 MARCH 2021 Transport Scotland ¡ The conflict study at Munlochy Junction shows that some drivers from the B9161 merging with the A9 southbound are not giving way to vehicles on the southbound carriageway and expect them to change lanes or slow down.
