Re: What do you think of the forum topics?

OK at this point in time. As people start to use it, there may be other topics to add or sub topics.

Topic: What do you think of the forum topics?

Hi All,

What do you think of the forum section topics?
Do you think we should have more topics, or should we change the existing topics around a bit?

Please feel free to comment.

Re: Best Practice

Hi Bridget

Chambers: We've used plastic chambers in Hamilton, some of them smaller, they tend to be ok as long as you have the trafficable (strong) ones.. although there is some skepticism about them so we usually try to keep them away from anywhere that a vehicle might track over the kerb over.

Kerb tails: Our tech spec prefers ducting under the kerb.. I don't think it happens much though!

On-road detector: We have thought about this recently but given the importance of detecting a cyclist (for the B light) and shadows etc causing problems, we've opted for push button. Then they know they've put a demand in too.

Controller types: We mandate VC6 controllers (ELV preferred) so that we have the latest benefits. I understand only ATC have had a VC6 for a few years now so we've only really been using them for new sites, I think we've been happy with their performance so far.

However, our maintenance team are in a much better position to answer your questions. I've passed it on to them and I will post any response I get.

Topic: Best Practice

We are looking to identify current best practice for a regional local authority for the following issues, does anyone have any commentary or advice regarding best practice when designing the following:

- Sawcutting for detector loops – the concern is the angle detector loops are bent in the figure 8 configuration and how any changes to sawcutting patterns will affect wearing course integrity. Does anyone have any advice/experience on issues with surfacing integrity when sawcutting or detector loop failure because of installation/bending issues?

- Chamber sizes and lid types - They have had difficulty installing standard size chambers due to conflicts with services and have had H&S issues with contractors manually lifting heavy chamber lids. Does anyone have any advice/experience on alternative chamber designs and lighter lids which are still trafficable?

- Milling of surfacing cutting off detector loop tails. Has anyone looked at adding an extra junction box within the carriageway to protect detector loop tails?

- On-road cycle detection – has anyone specified/trialled or designed on-road cycle detection with camera detection and a back up push button only?

- What controller types have been specified around the country and how do they perform? Does anyone have any advice/information on the controller types used in their jurisdiction and their benefits/performance?

Re: SNUG Name

Tim, presume you are just referring to the acronym, but there are many acronyms shared, so i don't thnk it's an issue that someone else has the same acronym. For example TSNZ is already shared by target shooting nz and train simulators nz.
Our actual name could (for example) be Traffic Signals NZ which will be unique, but the aconym shared.

The only issue i can see with having the same acronym is for the website address, but there are usually alternatives (e.g. tsnz.co.nz is used by trian simulators nz, tsnz.nz is used by target shooting nz, but it still leaves tsnz.kiwi available).

Re: SNUG Name

A couple of options would be TSNZ (Traffic Signals New Zealand) or SENZ (Signals Engineering New Zealand). Both however are already "taken".... by Target Shooting NZ and Radio Sport respectively. Finding names that aren't already in use by other NZ organisations may be difficult.
