the importance of streetlights

according to Urban, MOT data 2011/12,

1 in 112 daytime crashes are fatal 

1 in 56 night-time crashes are fatal

It is that night-time fatality statistic that drives me every day to make sure we get this right... every single time. 

'Close enough' is never 'good enough'. 

To get to the end, you have to start at the beginning - and the beginning is.....

 

Why we light roads...   the actual answer is two fold - and it depends on whether we are walking or driving.  

As pedestrians, we light roads so we feel safe- and we want to be able to see people or objects that could cause us harm. We also want to make our residential environments feel pleasant to be in - we want our lit areas bright enough for viability but not so bright as to cause annoyance.   This type of lighting is usually residential and typically 'PCat' classification where the  major focus is on the road and pedestrian space.

As drivers, we rely on both car headlights and the streetlights to provide us with visual information to assist us to make good driving decisions and to drive safely.  On VCat' roads, road carriageways are the focus area and many factors contribute to the calculations to ensure we install streetlights lights correctly - including vehicle speed, the number of  vehicles on the road, how wide the road is, road surface, column height and spacing and ambient area light (shops, houses, industrial areas etc.)  Neighboring residential properties or sensitive environments also typically need protecting.  Areas where vehicles meet other vehicles (e.g. intersections and merges) and people (e.g. pedestrian crossings and refuges) are absolutely critical to get right.   In our world, pedestrian safety sometimes extends to other projects such as under veranda lighting and public spaces e.g. parks, car parks and public areas.  We have been involved in some really great leading edge projects and have good experience to share. 

The rapid advance of longer life LED technology also allows us to care for our night-time environment more responsibly as well as potentially saving both money and resources on the quantity of electricity  consumed, network charges, infrastructure costs etc.

New Zealand and Australia have excellent guiding resources which can be followed in both the safety standards (New Zealand Standards Authority) and resource papers and research provided by the likes of New Zealand Transport Authority and a few local authorities.

Design and Comply Service:

A recent development with NZStreetlighting is that we are now able to offer a full design service. 

 

All suppliers, all luminaries, all optics, all costs, upfront so you can make informed decisions - from small maintenance based sites (intersections), local roads, state highways to whole town developments.  

NZStreetlighting has a strict focus on safety and compliance to NZ Australian Safety Standards NZAUS1158, NZTA M30 (accredited luminaries) and M26 (accredited columns), road categorizations based on industry proven practices - all this before project management and installation and even begins. 

Other considerations also made include:

  • colour temperature (k)

  • colour rendition (CRI)

  • future technology (drivers, CMS, control, dimming) etc.  

  • environmental protection

 

All recommendations are based on good solid  business practices in plain English and basic mathematics that everyone can  follow and solid decisions made - no industry gobbledygook here! 

Complete Scopes: 

Quality scopes are essential.  If you don't ask for what you want, then how do you know what you are getting back is correct?   

 

Scope outlines are obtained from contractors, civil engineers and direct from clients.  Information gathered includes GPS location, existing infrastructure, underground works, construction requirements, vehicular and pedestrian night time movements.  Environmental factors such as residential homes, schools, community centres etc are also included.   This information forms part of the design scope for our design and compliance service to work their magic.

 

LED 101

The rapid ascent of LED has revolutionized streetlighting, aside from potential financial savings on electricity there is so much more to this technology.  We are happy to offer an "LED 101"  presentations so decision makers can make informed decisions.

Funding:

NZStreetlighting is experienced in submitting complete business cases for funding approval  with over $25million completed, approved or waiting for approval.  

​ 

Project Management:

We also work closely with contractors to project manage either large geographic or technical installations.
