Dear Auckland Transport,

I have a couple of questions regarding the PB/5 pedestrian button used around Auckland.

1. Does pressing the button influence a signal change?
1b. Assuming it does, what actually happens within the traffic light system (at a high level)?

2. In some areas of the city (CBD), it appears at some locations are configured to trigger crossings at increased frequencies. Is this accurate?
2b. If so, what are the general boundaries where these areas of increased frequency start and end?

3. Is there a "default" crossing length that is set for most crossings or is it adjusted on a case-by-case basis?

4. There are some "variants" of the PB/5 such as buttons that have rectangular metal bars attached, presumably to stop cases of people kicking the button and other things like that. Was there any particular inciting incident that originally caused those additions to be made?

5. How much does a PB/5 button cost (roughly)?
5b. Who are the various suppliers (if more than one) for the PB/5 in Auckland?

I also acknowledge that I understand any response to this request will be delayed as Dec 20th to Jan 10th are not considered working days under the LGOIMA.

Yours faithfully,

Marcus
