Traffic Engineering

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.

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 ViaStrada project suggested the boundaries, specific techniques, design concepts, and implementation steps needed to create a pedestrian-friendly "slow core" for Christchurch.

Pedestrian LOS methodology outputChristchurch 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.

Following the 4 September 2010 earthquake, ViaStrada has been 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.

Preliminary design stage safety audit of a proposed roundabout at the intersection of a local road and a collector road. The roundabout is to replace the existing priority controlled crossroads.

ViaStrada recognise the need for careful horizontal and vertical geometric design to make roundabouts safer for all road users and bring this expertise to safety auditing of roundabouts.

The audit was carried out in accordance with Austroads and NZTA guidelines.
