Traffic engineering guidelines

ViaStrada and Abley Transportation Consultants were commissioned by the NZ Transport Agency to develop a national framework of guidance for planning and designing for cycling. This project came as a result of the NZ Cycling Safety Panel identifying a need for further guidance and was supported by industry feedback.

The resulting framework, titled Cycling network guidance - planning and design (CNG) was officially launched in July 2016. It provides comprehensive guidance and / or links to appropriate sources.

 

The objective of this project was to suggest whether Christchurch City Council (CCC) should continue its use of red coloured surfacing or change to green coloured surfacing for cycle facilities. We have examined a variety of factors, including international research, purpose of coloured surfacing, relationships with other special vehicle facilities, national consistency, connotations of different colours and logistics of change.

On the basis of national consistency and the superiority of green over red in terms of longevity, we recommended that Christchurch City Council adopt green as the new colour for cycle facilities. We suggested that this change can be implemented over a period of time. CCC adopted the recommendation at its 11 February 2010 meeting.

The Melbourne office of SKM engaged ViaStrada to peer review its draft report Green Lights for Bikes, a report on how road authorities can use a range of techniques to provide for bike riders at traffic lights. SKM's client for the report was Bicycle Victoria. ViaStrada provided several additional examples of techniques for this report. The majority of the techniques described will be relevant to urban road controlling authorities in New Zealand.

ViaStrada has developed a comprehensive design guide for trail designers and project developers. The updated design guide is available from the NZCT website or the ViaStrada website. The guide is applicable to all cycleway projects outside of urban areas, and not just NZCT projects.

NZTA commissioned ViaStrada to update more MOTSAM (Manual of Traffic Signs and Markings) material. Gone are all the old double limit lines, for example. The guidance on the marking of hook turn boxes for cyclists has been amended, and Section 2 now references the upcoming Austroads Guide to Road Design manuals.

ViaStrada has undertaken significant research and tool development on behalf of VicRoads (Victoria, Australia) to determine appropriate shared use path widths based on user volume characteristics. This work has been published as VicRoads Cycle Notes 21 on shared use path design.

Megan Fowler's first project at ViaStrada was to assist Tim Hughes of Land Transport New Zealand (now NZTA) in completing the Pedestrian Planning and Design Guide.

Transit NZ commissioned ViaStrada to update the cycling-related road marking content of the Manual of Traffic Signs and Markings (MOTSAM). In a parallel process, we were also assisting in a revision of the NZ Supplement to Austroads Part 14 Bicycles, the NZ cycling design manual (the revisions have now been published). We think the industry has been eagerly awaiting the outcome of these processes.

Should cyclists be allowed to ride across zebra crossings? When you've got a tricky question like this, who do you ask for sound and reasoned advice? VicRoads, the state roading authority for Victoria, based in Melbourne, sought the answer from ViaStrada. We reviewed international literature and based on this, gave our professional opinion on the merits of cycling across zebra crossings, signalised mid-block crossings, and crosswalks at signalised intersection.

A discussion paper on a proposed national road classification system (NRCS) or road hierarchy was prepared in mid July 2003 by Andrew Macbeth (at that stage, working for MWH New Zealand Ltd) with input on drafts from Transfund NZ and Transit NZ. The discussion paper was distributed to all road controlling authorities and other interested parties. Recipients were advised of the project, invited to respond to a survey about the proposed NRCS and invited to attend one of a series of five workshops held throughout New Zealand to discuss the proposed NRCS.
