Where costs are separable
Any service variations and new services that result in a higher annualised cost across the programme, and which are not part of the public transport continuous programme, are assessed as improvements.
In such circumstances they can be treated as small-scale service trials (if under $1,000,000 across the life of the trial), and be applied for as part of the low cost, low risk improvement programme. If the cost of the service provision exceeds this amount then the application should be treated as a stand-alone improvement, refer to Assessment of public transport improvements. The impact of such improvements on the programme as a whole should be assessed using the appraisal template [XLSM, 4.4 MB] to ensure the total programme is optimised.
Where costs are not separable
Where service variations resulting in a higher annualised cost across the programme cannot be separated out (such as reconfigured services in a total network), then application can be made as part of the continuous programme submission.
A stand-alone business case including robust identification of the problem, option development, and a benefit–cost ratio assessment should be provided to support the application. Again the impact of such improvements on the programme as a whole should be assessed using the appraisal template to ensure the total programme is optimised against a do-minimum ‘base case’ approach.
