Traffic Engineering Report

The CHR treatment should be 55-75m long plus storage. The Sidra analysis identifies an 95th
percentile queue of less than one vehicle on this approach. The design vehicle would be a 19m
long semi trailer and as such the overall length of the treatment would be 74-94m including
taper. The intersection design currently includes an 80m long turn lane excluding taper, which
is considered suitable.

7.2.           Holts Road/Taylor Court Intersection
TTM has assessed the performance of these intersections utilising Sidra analysis software
version 6.1. TTM used standard default settings in each case. Whilst this intersection has a BAR
treatment, TTM have modelled the intersection with only one approach and departure lane on
each approach as shown in Figure 7.3.

Table 7.2 gives a summary of the outputs for the 2029 Base and Development cases applied to
this intersection. It is noted that these traffic volumes are identical to the 2019 traffic volumes.
The Sidra files are provided with this assessment (Appendix E).
