Traffic engineering guidelines

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.

Christchurch City Council has an extensive Construction Standards Specification document. ViaStrada staff were engaged to lead a team of Council officers through the development of a new standard detail for intersection thresholds.

This project filled a big hole in New Zealand at the time. Austroads guidance was not always appropriate for New Zealand, and we have different road signs and markings. Practitioners needed local advice on how to design and implement cycle facilities. Transit (now NZTA) put up its hand in the national interest and agreed to fund the project.

The project was to provide real intersection and midblock layouts that practitioners could use to design and implement vision impaired ‘user friendly' facilities. LTSA (now NZTA) recognised that many vision impaired standards used ‘simple' or 'ideal' situations that could not be replicated in most design situations.
