1 Introduction 1.1 Background 1.2 Purpose of this Report 1.3 Summary of Approach 1.4 Report Structure
The Strategic Transport Projects Review (STPR) will make recommendations on a portfolio of land-based transport investments to be delivered between 2012 and 2022 that will most effectively contribute towards the Government’s overall Purpose to create a more successful country, with opportunities for all of Scotland to flourish through increasing sustainable economic growth. This Purpose will be achieved through delivery of the three Key Strategic Outcomes identified in the National Transport Strategy:
- Improving journey times and connections;
- Reducing emissions; and
- Improving quality, accessibility and affordability.
The output from the STPR will be focused specifically on strategic land-based interventions that require delivery or significant support from national government. To understand how the totality of transport interventions will contribute to the Government’s overall Purpose and the three Key Strategic Outcomes of the National Transport Strategy, consideration must also be given to the range of complementary transport interventions that may be brought forward by national, regional and local transport authorities.
For the purposes of the STPR, the National Strategic Transport Network has been defined as illustrated in Figure 1. The key elements of the network have been identified as:
- Urban Networks – the nationally significant parts of the transport network within the four largest cities of Aberdeen, Dundee, Edinburgh and Glasgow, aligning with the City Regions identified within the Cities Review and the National Planning Framework;
- Strategic Nodes – due to their location, Perth and Inverness act as strategically significant nodes on the national transport network; and
- Corridors – areas containing the transport network connecting the four largest cities and strategic nodes to each other, to the national boundaries, or to the peripheral and rural communities.
Two significant areas for transport investment have been brought forward ahead of the full review – the Forth Replacement Crossing1 and a report on rail improvements between Edinburgh and Glasgow2. In both cases, the economic and political priority given to such investment is clear, and advancing the feasibility work allows the benefits from the ultimate investment to be secured more quickly. Work undertaken as part of these reviews to identify and appraise interventions is not reported in this document.

This is the third in a series of reports produced as part of the STPR. Report 1 presented details of the existing and future performance of the strategic transport network. Report 2 detailed the policy expectations and national objectives that provide the framework for determining both the future required performance of the strategic network and the specific objectives that will deliver these elements of the national transport strategy.
This report presents the output from two of the STPR work packages: SWP5, covering the generation and sifting of interventions; and SWP6, covering the appraisal of those interventions that were considered to merit further appraisal.
SWP5 took the objectives presented in Report 2, and proposed a wide range of interventions to meet these objectives. Initial development of interventions was undertaken through internal workshops involving members of the Consultant’s team and the Scottish Government with knowledge and experience in a variety of transport fields. This approach brought a broad spectrum of experience, expertise and views to the intervention development process. In addition, a review of existing proposals was undertaken, largely by desk research and dialogue with Regional Transport Partnerships and the other STPR Reference Groups. A sifting process was then conducted to ensure that the interventions being taken forward are: within the scope of the STPR; contribute significantly to the objectives set; and are deliverable.
The purpose of SWP6 was to appraise the interventions which had the potential to make a significant contribution towards the STPR objectives and the Government’s central Purpose of achieving sustainable economic growth. The appraisal used the methodologies and criteria in the Scottish Transport Appraisal Guidance (STAG) which are designed to measure the deliverability and feasibility of proposed interventions in the context of the policy, economic and transport objectives which they seek to address.
This report describes the findings of the option generation, sifting and appraisal process, and presents details of the interventions to be retained following the appraisal process.
Chapter 2 of the report describes the generation and sifting process, covering the approach, sifting criteria, sources of the interventions and output from the process.
Chapter 3 provides details of the initial appraisal process, which particularly addressed multiple, mutually exclusive interventions which contribute to the same objectives. This allowed those interventions which contribute to each objective most effectively to be taken forward for detailed appraisal. A summary of each initial appraisal is given, together with the rationale for each conclusion reached.
Chapter 4 then outlines the detailed appraisal process and again highlights those interventions that have been retained following the initial appraisal.
