Transportation engineering

We undertake a wide range of transport engineering services, including
  • Road safety audits (all stages), including Safety Audit & Network Functionality (SANF) reviews
  • Scheme investigation studies for corridors, intersections and areas
  • Traffic signal designs and reviews
  • Speed management reviews/strategies
  • Pedestrian and cycle facility designs and reviews
  • Car parking and access design/reviews
  • Road safety and geometric design reviews
  • Level Crossing Safety Impact Assessments (LCSIAs)
  • Formal trials of new/innovative traffic control devices and design layouts
Notable recent projects include:

The City Council requested that an investigation be conducted into the possible conversion of part of Chester Street West to a one-way street. The study examined the advantages, disadvantages and operational issues associated with this concept.

Within the 4 Avenues (Central City) of Christchurch there are a considerable number of loading zones and short term parking restrictions. The City Council receives numerous requests for new loading zones, removal and alterations to existing loading zones. A comprehensive review was required so that the Council can make informed decisions. 

The section of Sparks Road between Halswell Road and Hendersons Road has been the subject of concerns raised by local residents. These concerns relate to the perceived high volume of heavy vehicles, the perceived excessive speed of vehicles and the overall level of safety of the road and specifically the level of safety at the Milnes Road intersection.

This project was carried out by Axel Wilke whilst he was still employed by Christchurch City Council (CCC), and Wayne Rimmer (Landscape Architect). Axel and Wayne were commissioned to develop a strategic plan for the section of the Avon River between Kilmore and Barbadoes Streets as part of the CCC Avon River (Central City) Masterplan.

The concept has subsequently been implemented for Cambridge Terrace between Barbadoes and Peterborough Streets.

The Port Hills is a precious environment that requires sensitive design that meets the need of all users. The objective was to accentuate the passive use of the area while accommodating vehicle access.

Invercargill City Council is faced with some challenging traffic engineering at this rural intersection. ViaStrada was commissioned to confirm their conceptual design. We identified some areas that will need specialist input during the detailed design phase.

ViaStrada has assisted MWH Hamilton with reviewing a proposed signalised T intersection in Hamilton. The client wanted us to identify potential cost savings. We developed variations on a broad concept which enhanced safety for motorists, pedestrians and cyclists and could save the client $100,000 to $150,000.

Halswell Road is part of SH 75 through Christchurch, with Transit NZ intending to signalise the intersection. Christchurch City Council tasked ViaStrada with peer reviewing the design by Transit’s consultant.

ViaStrada was engaged by Christchurch City Council to improve the traffic management on Riccarton Road. Together with baseplus as a sub-consultant, ViaStrada has developed a concept that will greatly improve the intersection performance.

Local residents were concerned at the level of road safety along Swanns Road and at intersecting side roads. The project involved an examination of the safety concerns and an overall analysis of traffic volumes, speeds and crashes.
