2 Option Generation, Development and Sifting Process

2.1 Approach

This Chapter describes the method used for generating intervention packages for consideration in the appraisal process of the STPR. This follows on from the identification of constraints and opportunities presented in Report 1 and the setting of expectations and objectives shown in Report 2.

The methodology for generating, developing and sifting proposed intervention packages is shown in Figure 2. The generation and sifting process was informed by:

The Government’s central Purpose of increasing sustainable economic growth;
Key Strategic Outcomes of the National Transport Strategy, and the network investment hierarchy;
Constraints and opportunities across Scotland’s transport network highlighted in Report 1;
National objectives and specific objectives for urban networks, Strategic nodes and corridors, as listed in Report 2; and
Aspirations and proposals of key stakeholders.

Figure 2 Approach to Intervention Generation and Development

2.2 Initial Generation of Interventions

Interventions were developed in progressive stages, with a series of iterative refinements to improve their focus and effectiveness. Further recognition of the investment hierarchy was considered when identifying appropriate levels of interventions. The hierarchy is:

Firstly, maintain and safely operate existing assets;
Secondly, promote a range of measures, including innovative solutions, to make better use of existing capacity (interventions may include technology based, fiscal and ‘soft measures’ in addition to engineering solutions); and
Thirdly, promote targeted infrastructure improvements.

The STPR will therefore not bring forward recommendations for infrastructure improvements without first considering the requirement for, and effectiveness of, interventions in the first two categories.

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 wide range of experience, expertise and views to the intervention development process. All members of the workshops were familiar with the issues, constraints and opportunities detailed in Report 1, together with the objectives detailed in Report 2.

Interventions were initially developed with a focus on addressing the specific issues within the urban networks, strategic nodes and corridors. Further development work was then undertaken to address, where possible, national and cross corridor issues to identify appropriate interventions.

2.3 Existing Proposals

It is important to take due cognisance of the views of stakeholders when developing the potential options to be taken forward within the STPR. Consequently, a review of existing proposals was undertaken, largely by desk research and dialogue with Regional Transport Partnerships and the other STPR Reference Groups. This identified proposals that may address particular stakeholder objectives but did not necessarily match those of the STPR. Some stakeholder-generated proposals were considered for the STPR providing they were within the context of Government policy and the STPR objectives. Those which were within context and scope were taken forward to the subsequent development of intervention packages. Those considered not being in context or scope are listed in Appendix B.

2.4 Development of Intervention Packages

A key principle of the STPR is that interventions should make a significant contribution to the objectives defined in Report 2. Emerging interventions were assessed against these criteria. Those which did not meet the criteria were considered for packaging together with other complementary interventions. Those which were not packaged in this manner were not taken forward for further appraisal and are listed in Appendix B.

The packaging process brought together complementary interventions to optimise their chances of appraisal success in the progression following initial and detailed appraisal stages at a scale of operation commensurate with the STPR. Initial packages were therefore defined at a high level and could contain specific interventions essential to their definition and others that were valuable but not essential. Interventions that were taken forward to the formal appraisal process were then reviewed and, if appropriate, defined in a greater level of detail.

2.5 Deliverability of Interventions

Developed intervention packages were assessed against deliverability criteria. This included consideration of any major potential legal, technical, financial or environmental obstacles to delivery within the STPR timescale. It is expected that the STPR will not specifically include interventions that are the responsibility of Local Authorities and Regional Transport Partnerships to develop and deliver. However, it is recognised that a range of delivery partners will be needed for measures which address both national and local objectives. Those that were not considered viable due to deliverability issues were not taken forward, and are listed in Appendix B.

2.6 Output from Option Sifting Process

Table 2.1 lists those interventions that were considered to merit further appraisal within this review. Further details of these interventions and the specific objectives that they meet are contained in Appendix A.
