APPENDIX B –GIS-BASED ASSESSMENT INTERPRETATION RESULTS

by M G Winter and F Macgregor

B.1 INITIAL INTERPRETATION

In this section the results of the initial interpretation of the GIS-based assessment is presented. This details sections of the trunk road network that were defined as candidates for Main Study, Opportunistic and Other (None) as described in Section 5.

‘Comments on Hazards’ were made as aide memoire to the authors for use during the process and were not intended to provide any kind of definitive statement regarding the hazards.

B.2 SECONDARY INTERPRETATION

In this section the results of the second stage interpretation of the GIS-based assessment is presented. This divides the sections of the trunk road network that were defined as candidates for Main Study into Priorities 1 to 4 and identifies two sections for Separate Assessment as described in Section 5.

‘Comments on Prioritisation’ were made as aide memoire to the authors for use during the process and were not intended to provide any kind of definitive statement regarding the hazards.
