Small and local scheme assessment

Small and local scheme assessment

Final workshop of the DISTILLATE programme

Great Minster House, London

Tuesday 22nd January 2008

Objectives

Objectives

  • Overall Project G objective:

  • To develop appraisal methods which reflect the requirements of sustainability

  • Small and local scheme assessment:

  • Methods for appraising small schemes

  • Looking at the inconsistencies between targets and appraisal:

  • Appraisal methods and sustainability


Small and local scheme assessment1

Small and local scheme assessment

Motivation came from local authority requirements:

  • Proper assessment of small (non major) schemes

    • prioritisation

    • analysis

    • assessment of behavioural and attitudinal measures

      • publicity campaigns

      • intensive marketing

      • targeted travel advice

  • Assessment against targets/indicators (not formal appraisal)

  • Transparent process

    • A number of methods had been developed for individual authorities but worked as a black box

  • Authorities wanted a decision support tool NOT a decision making tool


Methodology

Methodology

The tool is an (Excel based) assessment matrix with the following stages:

1. Select indicators to be included in assessment

2. Weight the indicators on a scale of importance to the LA (1-5)

3. Assess the impact of each proposed scheme against the indicators (scale -3 to + 3)

4. Score = ∑importance*impact score for all indicators for each scheme

5. Estimate cost of scheme

6. Compare score and cost across all potential schemes

Use

  • The tool can be used to:

    • Compare individual schemes

    • Compare packages of schemes

    • Provide a quick NATA style assessment using the NATA indicators

  • Pick lists of indicators to select from are provided from a range of sources e.g.BVPI, Local Area Agreement, quality of life

  • Can tailor indicators to the scenario

  • It produces a total score against the selected indicators which can be compared with the estimated cost of the scheme (s)


Output score vs cost per scheme

Output: Score vs Cost per scheme


Output score by indicator

Output: Score by Indicator


Looking at the inconsistencies between targets and appraisal

Looking at the inconsistencies between targets and appraisal

Motivation came from local authority concerns:

  • Formal appraisal (NATA) as a barrier to the delivery of sustainable transport schemes

  • Role of appraisal in decision making

  • Particular concerns:

    • Importance of travel time savings (and treatment of fuel duty)

    • Value for Money and achievement of objectives


Exploration of the issues

Exploration of the issues

  • Partly looking at the political and practical issues around appraisal

  • What should the relationship be between appraisal, VfM, and the choice of schemes to deliver policy?

    • the potential inconsistences between appraisal/VfM and “policy fit” (or achievement of targets)


Nottingham turning point

Nottingham Turning Point

  • “ticked all the boxes” in terms of policy (good “policy fit”)

  • Poor VfM (BCR -1.65)

  • Built despite this

    Widely regarded as a successful scheme


Addressing the problem

Addressing the problem

  • Review of possible approaches:

    • Aligning the indicators used, their relative weights and the target values with the criteria used in appraisal

    • Setting targets to be consistent with the outcome of an appraisal of a complete strategy to achieve sustainability objectives

  • The aim will be to increase the consistency and transparency with which decision making is carried out and raise awareness of this important issue

    No easy answers!
