Nelson City Council (NCC) has difficulty in some of the older areas of town in implementing standard compliant roading asset renewals due to the restrictive nature of grade and road reserve width. As a response to these issues, NCC has implemented three shared zone projects where the road upgrade reduces the requirements set out in the design manuals and provides a space in which vehicles, cyclists and pedestrians all share the same road space. Rather than providing footpaths and full parking width, the road is constructed in a way that formalises the existing narrow nature.

This dissertation intends to provide a means by which to assess existing zones based on how well they meet the objectives they set out to achieve, and provide the ability for NCC to assess the suitability for future upgrades.

A literature review was undertaken based on global and local best practice in this space. It was found that whilst the zones are meeting the basic requirements of shared space, there is significant room for improvement.

A set of performance objectives, and criteria by which to assess them, were developed based on the literature. It was intended that the objectives provide a qualitative and quantitative means by which to assess the shared zones.

A comparative assessment has been undertaken between a shared zone design treatment and a standard compliant treatment based on the selected candidate site of Airlie Street, Glenduan. It was found that the shared zone treatment has a positive benefit over existing maintenance regime. Quantifying the cost effect that benefits provided have on the net present value was not undertaken however it is hypothesised due to the low volume nature of the roads, these effects will be minimal in relation to the capital outlay of the projects.

Finally a guidance document was produced based on this work. This is presented in draft form with the intention of obtaining Council approval for its use. Further analysis of some of the existing shared zones is yet to be undertaken. This was deemed beyond the scope of this project.
