Research and publications

ViaStrada staff have published many papers, articles, reports and other technical documents, to conferences, national clients, and public media. A number of these publications have won industry awards.

Recent publications are shown below; you are welcome to reference these in your own work. Feel free to contact the relevant authors for further information as well:

Gemma demonstrated the planning and design methods employed by a multi-disciplinary team to deliver 13 major cycleways.

This interactive presentation involved giving words to participants to evoke what things people think about when considering the public street.

buffer marking graphicA cycle lane marking trial on Dunedin’s Cumberland Street (State Highway 1) was undertaken. Non-standard road markings for cycle lanes were tested for their effectiveness. The purpose of this trial was to establish to what extent changed road markings can influence the relative positioning of parked vehicles and cyclists in an adjacent cycle lane. It was acknowledged that many cyclists may not be aware that their actual greatest mid-block risk stems from opening car doors, and they may consider themselves to be more at risk from moving traffic. As such, we measured whether changing the marking style can change behaviour without having to explicitly educate cyclists where best to cycle and motorists where to park. The desired effect was an increased separation between cyclists and parked vehicles.

Ideal MaaS appWho should develop and manage “Mobility as a Service” (MaaS) services in New Zealand? Three approaches that have appeared to date are (1) private transport service operators themselves, (2) central/local government transport organisations, or (3) independent software developers. Each approach has its advantages and disadvantages, for example in regard to coverage of available services, data supply and management, and integration with payments. At the 2019 T-Tech Conference in Christchurch (May 2019), Glen outlines the options and issues afforded by each approach, using examples from around the world.

200 and 300 mm aspectsChristchurch City Council and Auckland Transport commissioned ViaStrada to conduct an official traffic control device trial of directional traffic signals for cyclists. The new signals have been installed at four intersections.  Assessments of user behaviour (compliance and conflicts), user understanding, and user satisfaction have been undertaken at three of the intersections and will soon be carried out at the fourth.

This paper was awarded the best research paper at the conference.

72 secondsWith a new government pushing a greater emphasis on road safety, attention is increasing on the role that speed plays in our safety record. For both urban and rural settings, there has been a growing clamour by some elected officials, safety advocates, and the general public for greater use of lower speed limits. Yet, at the same time such changes remain polarising, with other people sceptical of their effect on safety and wary about their impact on network efficiency. The relatively cumbersome process of changing existing speed limits has also been cited as a hurdle to implementing fast change.

This paper was runner-up to the best research paper at the conference.

Lots of LimesJohn Lieswyn chaired a panel discussion on micro-mobility. There were eight panellists representing a variety of groups, interests, and companies.

graphicThe most important finding is that the school travel plan (STP) process itself can be the seed of a more productive collaboration between council staff, school administrators, board members, and parents. There is an opportunity to tie the development of an STP to road safety and infrastructure funding.

Chch 30kmh gatewayIn 2016, Christchurch introduced a 30km/h lower speed zone within a large part of the central city area. While this has generated some controversy amongst residents and businesses, preliminary analysis of crash data before and after suggests that there have been considerable reductions in crash numbers and injuries since its implementation, despite growing numbers returning to the city. Glen presented these findings to the 2018 Transport Knowledge Conference in Wellington.

Rattray St gatewayDunedin City Council commissioned ViaStrada to develop an area-wide approach to addressing road safety and parking issues around five central city schools. By considering the whole study area as one precinct (the “Central Schools Cluster”), a series of consistent treatments could be used to manage behaviours and minimise safety and operational issues. Glen Koorey and Hjarne Poulsen (Dunedin CC) presented the findings and implementation to date at Trafinz 2018 in Wellington.
