Subject: PRINTED Official Information request - Access to raw data concerning motorway onramp signals
From: Tom Atkinson <
[FYI request #7881 email]>
To: Official Correspondence <
[NZTA request email]>
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
