Access to raw data concerning motorway onramp signals
Tom Atkinson made this Official Information request to New Zealand Transport Agency
The request was refused by New Zealand Transport Agency.
From: Tom Atkinson
Dear New Zealand Transport Agency,
in regards to onramp signals in both directions where possible:
420 ESMONDE ROAD
435 GREAT SOUTH ROAD / PENROSE
424D UNION ST / CENTRAL MOTORWAY JUNCTION
424C WELLINGTON ST / CENTRAL MOTORWAY JUNCTION
I would like to have access to raw data concerning motorway onramp signals sufficient to:
- prove or disprove the hypothesis that they assist in improvement highway flows
- use with other data I will source independantly, prove or disprove the hypothesis that they assist in reducing C02 emitted by vehicles
- understand the conditions that trigger them to activated and deactivate each day
- be multi-month data sets ideally with control data from my proposed 5 week test
- understand if this activation is correlated to anything or just put on a timer or set by humans
- have access to activation sensor data / timing data schedule data also to correlate
- be able to count total traffic flows from the data set itself
- be in a format I can open eg, CSV, XLS, SQL, JSON, TXT etc.
- be able to create my own per-minute summaries of traffic flows from the data set, eg "between 2:57pm and 2:58pm the signal was not active and 23 cars went through" etc.
- if you can please assist by helping to create fresh control data using time correlation: manually disabling **all the mentioned signals weeklong** then a week of space then off then on then off then back to the status quo meaning on, taking 5 weeks ultimately from start to finish.
- I can use data from the weeks with the signals disabled to discover what happens to the motorways precisely
- As much as I dislike the signals, perhaps the ensuing Chaos would reenforce they are a good idea to myself and others? Or perhaps the traffic will be so much greatly improved by the "stochastic flow" that we **come to our senses** and disable them permanently?
It is my belief that a more stochastic driving style is beneficial to increasing traffic flows during congestion, and that the signals are only of use if alternative routes are available such as not on the north shore of Auckland.
Yours faithfully,
Tom Atkinson

The response to this followup request will be useful if you want to take this to the Ombudsman. 11.3 (d) of the user agreement allows release of confidential information as required by law, so there's a strong argument that they are not in fact barred from releasing it
https://fyi.org.nz/request/9404-auckland...
Things to do with this request
- Add an annotation (to help the requester or others)
- Download a zip file of all correspondence
Offensive? Unsuitable?
This request has been marked for review by the site administrators, who have not hidden it at this time. If you believe it should be hidden, please contact us.

I know it's been a few months now, but I'd suggest you might try complaining to the Ombudsman about this refusal if you haven't already.
Information held by independent contractors, in their capacity as a contractor to a government agency, is considered to be held by that agency. See Section 2(5) of the OIA:
"Any information held by an independent contractor engaged by any department or Minister of the Crown or organisation in his capacity as such contractor shall, for the purposes of this Act, be deemed to be held by the department or Minister of the Crown or organisation."
I am not a lawyer, but I do not think NZTA is justified in denying your request because the information has been provided to them by an independent contractor under an obligation of confidence. So long as the information is held by the contractor in their capacity as a contractor to NZTA, as I think would certainly be the case here, then it is already official information. The contractor clearly cannot supply itself with information under an obligation of confidence, so Section 9(2)(ba)(i) of the OIA cannot apply to it.
