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 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.

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.
