How can we help?

In relation to Coolmine, what order (if there is one) have the options been discounted?


A multi-criteria analysis (MCA) mechanism was developed on the basis of “Department of Transport Tourism and Sport (DTTAS), Common Appraisal Framework (CAF) for Transport Project and Programmes March 2016” for options assessment. It includes the following six appraisal criteria as follows:
  • Economy,
  • Safety,
  • Integration,
  • Environment,
  • Accessibility and Social Inclusion, and
  • Physical Activity.
Multi-Criteria Analysis – MCA can be used to describe any structured approach to determine overall preferences among alternative options, where the options should accomplish multiple objectives. The term covers a wide range of techniques that share the aim of combining a range of positive (benefits) and negative (costs) effects in a single framework to allow for easier comparison of alternative options in decision-making (CAF, 2016). The Options assessment process for DART+ West was a two-stage multi-criteria analysis. The first stage, MCA1, identifies options that are not feasible and options which are obviously inferior to others based on the six appraisal criteria. The second stage, MCA 2, is a more detailed assessment of the higher ranked (feasible) options from MCA1. In the case of the Coolmine Level Crossing, eight Options, in addition to the Do Nothing and Do Minimum options, were assessed as part of MCA 1. Four of these options were deemed feasible and more advantageous compared to other options based on the CAF criteria. The Do Nothing and Do Minimum options were not deemed feasible. The options brought to MCA 2 were Option 1, Option 3 with Footbridge, Option 4 and Option 6. Following a detailed MCA 2 assessment it was deemed that Option 3 with a footbridge was the emerging preferred option on the balance of the CAF criteria compared to other options considered.
