Dear New Zealand Transport Agency,

 

Under the Official Information Act, I request all information held by Waka
Kotahi NZ Transport Agency relating to the assessment and modelling of
traffic flows at the Cambridge Southern Interchange on the Waikato
Expressway.

 

This request covers information used to justify decisions not to upgrade
the interchange to full access, including but not limited to:

 

1) When NZTA conducted its most recent traffic flow modelling relevant to
the Cambridge Southern Interchange.

 

2) Where the traffic data used in that modelling was sourced from
(including specific traffic counts, third-party datasets, or local
authority data).

 

3) Population growth models for Cambridge used in that modelling,
including the source of those projections and the version/date of the
dataset.

 

4) Any modelling assumptions, reports, and methodology notes relating to
the Cambridge Southern Interchange, including assessments comparing its
location to the Victoria Road interchange.

 

5) Any analysis or examples NZTA has considered when citing that the
Cambridge Southern Interchange is "too close" to Victoria Road interchange
and would result in mainly local traffic as reported
[6]https://aus01.safelinks.protection.outlo...
. Including comparisons to interchange spacing elsewhere in the Waikato
Expressway or Hamilton area.

 

6) Copies of any NZTA/Waka Kotahi policies, guidelines, or criteria relied
upon when determining whether to upgrade the Cambridge Southern
Interchange to a full access interchange.

 

Yours faithfully,

 

AJ
