Appendix E - Traffic Engineering Assessment Report

Modus has prepared Sight Distance Drawings, provided at Appendix B, indicating the minimum SSD
requirements as well as the sight distance extents needed to achieve the minimum SSD requirements.

For ease of reference, the driver perspective at the minimum SSD requirements are illustrated below
in Table 5.

Table 5   Lot 2 Access Sight Distance Review

               Approach From West                                 Approach From East
              (80.0m From Driveway)                             (88.4m From Driveway)




Therefore, the existing horizontal and vertical road alignment of Black Mount Range Road allows
capability for the minimum SSD requirements within the Austroads Guide to Road Design series as
well as Australian Standards 2890.1 to be accommodated.

However, existing vegetation within the Black Mount Range Road verge impedes the available sight
distance.

On this basis, it is recommended that the existing vegetation within the Black Mount Range Road
verge be removed (as demonstrated at Appendix B) to accommodate acceptable sight distance
achievements for the Lot 2 access.
