Contra-flow cycling signAuckland Transport commissioned ViaStrada to develop and investigate some options for providing contraflow cycling on three suburban one-way streets. 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.

ViaStrada designed the internal roads for Nazareth House, a retirement village and healthcare complex in Christchurch. The brief was to create a slow speed environment where drivers felt like guests, so that elderly residents walking along or crossing the roads felt safe. The 'at-grade' or level surfaces make it very convenient and accessible for the residents to walk in and out of their homes to their unique street environment.

ViaStrada was engaged to develop the first package of concepts and scheme designs for the South Dunedin Cycle Network, providing cycle facilities with community connections that will link to a wider network suitable for cyclists of all ages and abilities.

ViaStrada has been commissioned by VicRoads (the state roading authority of Victoria, Australia) to undertake research on physical bicycle lane separators. Undertaking the trials included site selection, design of the empirical study and evaluation of the results. The aim of the study is to establish whether the devices are safe for all road users and effective in reducing the occurrence of drivers utilising the cycle lane. The trials are currently under way.


ViaStrada were engaged by DOC to carry out a post construction safety audit of the shared walking and cycle tracks to Franz Josef and Fox glaciers.

ViaStrada were engaged by Nelson City Council to provide a concept design including cross sections, rough order costs and scheme alignment plans for a proposed cycle facility that is suitable for use by cyclists of all ability and confidence levels, with the proposed facility ideally separated from moving traffic.

ViaStrada was commissioned by Auckland Transport to edit and review a red light camera pilot evaluation draft report and provide an international literature review. The project was completed in one week.

The Kaiapoi Town Centre, Integrated Transport Plan involved site visits, consultation with stakeholders including trucking firms and retailers, working closely with a Community Reference Group, SIDRA intersection modelling, option identification and assessment, and concept designs.

We don't just rely on high tech software, but when we have to design to low tolerances, we do real-world simulation testing to confirm design parameters and build stakeholder support!

This scoping study for a separated bicycle facility (where cyclists are physically separated from motor vehicles) analysed a variety of routes and design cross-sections between the University of Canterbury and the Christchurch central city. The project, which preceded the Christchurch earthquakes, provides valuable information on the feasibility and costs of separated cycle facilities. There has been considerable public support for cycling through the CCC's public consultation on how to rebuild Christchurch.
