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:

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.

The study provides an analysis of the existing traffic environment and makes recommendations on appropriate remedial measures where necessary. The study has been conducted in the context of Local Area Traffic Management (LATM), which is supported by a number of Council strategies and the legal strategic framework of the City Plan.

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.
