TransportNI carries out a comprehensive appraisal of each strategic road improvement proposal. The appraisal procedure requires a clear understanding of the objectives which are to be met, and appropriate criteria to be used, to decide whether a proposal meets them.
Scheme assessment reports act as a summary of the more technical reports generated during the appraisal of road schemes. Scheme assessment and reporting is a three-stage procedure. The level of detail and coverage of the assessment and the report is appropriate to the type of decision that can reasonably be taken at each stage.
Stage 2 identify the factors to be taken into account in choosing alternative routes or improvement schemes and to identify the environmental, engineering, economic and traffic advantages, disadvantages and constraints associated with those routes or schemes. This concludes in the selection of a preferred route or scheme option.
