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: A selection of recent relevant projects is shown below:

The Avonside / Fitzgerald project has two 'drivers':

The Fitzgerald bridge over the Avon River needs to be earthquake strengthened, and the adjacent intersection has a high crash record.

Our team has undertaken the traffic engineering design work for the intersection upgrade.

Traffic signal improvements to the Kawarau Falls single lane bridge, to meet Transit NZ safety and efficiency requirements, to allow the side road to access the State Highway for the development of the Kawarau Falls project.

When the new Bunnings site on Marshland Road was developed, traffic signals were needed to ensure safe site access. ViaStrada was engaged to undertake the design off traffic signals for the new Bunnings site, and upgrading an adjacent existing signalised intersection (Briggs / Lake Terrace / Marshland) that is affected by the development.

SH7 and Fairhall Road intersection design for the Kaiata industrial park. This required a specialist intersection design catering for heavy commercial vehicles (HCVs) on a high speed State Highway environment.

The purpose of this review was to identify whether the integrity of the original proposal for three off-road cycle paths from Waitakere City Council (one of the 7 councils in the Auckland region), as reviewed and approved by Infrastructure Auckland, had been retained in the current tender drawings. ARTA also required advice on whether it should approve construction for the Lower Waikumete Path, the Oratia Stream Path, and the Lower Opanuku Path.

The Little River Rail Trail is planned to extend from Hornby (Christchurch) to Little River on Banks Peninsula. ViaStrada undertook this investigation into the feasibility of providing a rail trail from Hornby to Prebbleton as part of the Christchurch – Little River Rail Trail.

Christchurch City Council has ambitious plans for bus priority. In 2006 ViaStrada was engaged to design bus priority measures for the #70 Queenspark corridor. This was an exciting project, pushing the boundaries of urban traffic engineering measures.

ViaStrada has been tasked to assist with gaining NZTA approval for site access to the 32ha Five Mile development from SH6.

This report presents the findings of an audit of a sample of 10 of the traffic signal controlled intersections operated by DCC. The purpose of the audit is to identify issues with signal design, maintenance and operation, and make recommendations that will help improve the safety and efficiency of traffic signal control.

Recent development of residential subdivisions in the north west of the city has resulted in a substantial increase in traffic activity on a number of roads in the area. The increased activity has not been limited to vehicular traffic but it is evident that pedestrian and cycle activity has also increased. Previously many of the roads experienced very little traffic activity.
