The analysis shows that the intersection of David Low Way/Heron Street/hotel access is
capable of accommodating the traffic which is likely to be generated by the proposed
development.

5.6.2 .David Low Way/Unnamed Access Road

The intersection of the unnamed road providing access to the development. with
David Low Way has been assessed. In recognition that the median is wide enough to store a
right turning vehicle, it has been considered that a staged right turn is possible at this location.
As such, the assessment has been based on basic gap acceptance theory (as per the ‘Traffic
Engineering Practice’, Ogden and Bennett) and a spreadsheet analysis too! which has been
developed by Cardno Eppell Olsen.

The results of this analysis, which shows the results for the turning movements only (i.e. not
the through movements) can be found at Appendix D and are summarised in Table 5.3.

The analysis shows that the T-intersection as it is currently formed is capable of
accommodating the traffic which is likely to be generated by the proposed development. This
is, in part, due to the ability for a vehicle turning right out of the unnamed access road to
complete a two-part turn by propping within the central median.
