Transportation engineering

ViaStrada provides a range of traffic and transport engineering services, with a particular emphasis on safe and sustainable solutions. Some of our areas of expertise include:
  • Road safety audits
  • Intersection concept design
  • Planning/design for walking and cycling
  • Traffic calming and speed management
A selection of recent relevant projects is shown below:

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.

Reduced traffic speeds have been shown to improve central city liveability and street activity levels. This 2011 ViaStrada project suggested the boundaries, specific techniques, design concepts, and implementation steps needed to create a pedestrian-friendly "slow core" for Christchurch. A new 30km/h slow core has now been implemented in 2016, largely mirroring the area suggested by ViaStrada.

Christchurch City Council commissioned an investigation into ways of improving pedestrian level of service (LOS) at traffic signals in the central city. The underlying hypothesis of this project is that improving the pedestrian level of service of the central city will increase prosperity.

ViaStrada developed a method of measuring pedestrian LOS and applied this to 32 signalised intersections with 110 pedestrian crossings to develop a detailed proposal for each.

This study focused on enhancing the walkability of the Greymouth Town Centre.  The comprehensive final report covered high level strategic planning through to detailed recommendations for site specific design investigations.

 

roundabout designViaStrada was engaged by the NZTA to carry out a detail design stage safety audit of a proposed roundabout on Tay Street, Invercargill.

Following the 4 September 2010 earthquake, ViaStrada was engaged by Waimakariri District Council to provide traffic engineering advice to create streetscape concept designs that reflect the needs and desires of the residents for a range of transport choices.

ViaStrada was commissioned by Palmerston North City Council to peer review the concept plans of proposed changes to Walding Street, an arterial road that forms part of the city's ring road system.

ViaStrada's traffic engineers undertook a scheme design stage safety audit of a proposed upgrade of Elles Road, Invercargill. Elles Road is a busy arterial in a commercial area of Invercargill and features many commercial entrances, traffic signals and a pedestrian crossing. The audit was carried out in accordance with Austroads and NZTA guidelines.
