Simon Kennett presentingIn June 2016, the New Zealand Transport Agency launched the Cycling Network Guidance – planning and design guide. This web-based collection of planning guidance, design tools, case studies and links to other guides was seen as an important step in having the Urban Cycleways Programme deliver best-practice facilities of a consistent quality nationwide.

Example slideRoundabouts are the safest form of intersection control for motor vehicle occupants. Numerous studies have shown that, in general, fewer casualty crashes involving only motor vehicles occur at roundabouts than at intersections controlled by traffic signals, stop, or give way signs. However, injury crash rates for cyclists at roundabouts in Australasia are typically higher than at other intersection types, with the predominant crash type involving a circulating cyclist being struck by an entering motorist.

It was presented by Axel Wilke, and others who contributed to the topic were Alistair Woodward (University of Auckland) and Jürgen Gerlach (University of Wuppertal, Germany).

Crash rate comparisonThe German word for “roundabout” is “Kreisverkehr”. The German word for “cycle-friendly roundabout” is “Kreisverkehr”. In case you missed it, that’s the same word. Since all urban roundabouts designed according to the German guidelines are automatically cycle-friendly, there’s simply no need for another term. This article reflects on differences between German and Austroads design guidance, and the vastly different safety outcomes. Austroads roundabouts can be negotiated at much higher speeds, and consequently they are much less safe.

Ferry Rd option 1Axel Wilke addressed the Christchurch Infrastructure, Transport and Environment (ITE) Committee in June 2017 about options under consideration for the Ferry Road major cycle route (MCR) between Fitzgerald Avenue and Wilsons Road.

Auckland Transport commissioned ViaStrada to investigate some options for providing contraflow cycling on three suburban one-way streets, as well as reviewing the design for another central city contra-flow route. In the absence of current design guidance or practical examples for New Zealand, a “first principles” approach was taken to consider all possible ways to provide for contra-flow cycling on the streets in question.

This paper outlines the process undertaken to develop and assess contra-flow cycling options for Auckland. The paper was presented by Glen Koorey at the 2017 IPENZ Transportation Group Conference, and co-authored by Warren Lloyd (ViaStrada) and Malcolm McAuley (Auckland Transport).

Glen Koorey presented 'Changing Rural Speed Limits - Learning from the Past' at the 2017 IPENZ Transportation Group Conference. The paper, co-authored by Bill Frith of OPUS, was Highly Commended (runner-up) for Best Research Paper.

New Zealand is reviewing its procedures for setting speed limits as part of the "Safer Speeds" component of the national road safety strategy. A big topic for discussion is the planned greater use of speeds limits below the standard 100 km/h rural or "open road" speed limit. This paper draws on earlier studies of two past case studies of NZ speed limit changes, and re-analyses the findings in light of more recent research.

This paper looks at ways of addressing conflict between people on bikes and motor vehicles at signalised intersections that have separated cycleways on their approaches. Megan undertook a background literature review and visited seven cities in North America as part of a study tour. She investigated relevant sites with a variety of different treatments and spoke to people involved in the planning, design and operation of those sites.

The NZ Transport Agency engaged MWH and ViaStrada to investigate options for amendments to several give-way related road user rules. Our report was published on the Transport Agency website in February 2017. Follow up work with regards to drafting some of the Road User Rule amendments is underway.

Vancouver West End greenwayGlen Koorey gave two presentations at the Neighborhood Greenways workshop held in Washington DC, US, as part of the 2017 Transportation Research Board (TRB) Annual Meeting. This workshop was convened to explore the state of research and practice for neighbourhood greenways in North America and the world, and to identify priorities for future research and project development.
