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:

Separated cycle lanesViaStrada was commissioned to conduct safety audits of the uni-directional separated cycleway pair on the one-way system in central Dunedin, on State Highway 1 between Pine Hill and Rattray Street. 

Speed and volume graphicFor five schools in the central city, ViaStrada developed an area-wide plan for road safety improvements including options for the optimisation of on-street parking. The work include a full review of parking capacity, occupancy, speed and volume data.

Aerial image of the roundaboutMarlborough Roads engaged ViaStrada to develop an improved roundabout design for the Alabama Road and Weld Street intersection. This site has residential houses on three quadrants and a large supermarket on the fourth quadrant. The roundabout improvement project builds on the previous cycle safety assessment ViaStrada undertook in early 2018 of five roundabouts and four routes in Blenheim. Of the five roundabouts studied, the Alabama Road and Weld Street roundabout had the second highest number of cyclist-involved crashes (9 crashes recorded in the CAS database).

design planPNCC engaged ViaStrada to undertake scheme and detail design stage road safety audits of a number of roundabout upgrades at city intersections.

QAC plotA significant increase in passenger numbers at Queenstown Airport put pressure on many parts of the existing infrastructure. ViaStrada developed multiple concept through to design plans including significant changes to the roading network and car and coach parking areas. All proposed works were incorporated in a staged Master Plan.

Location planViaStrada was engaged by the NZ Transport Agency to assess the impact of a proposed new subdivision on the existing local road network.

Scheme design of cycle linkViaStrada was commissioned to prepare a concept plan with design options for the Eltham Road / Beaver Road corridor, an important north/south link across Blenheim that serves three major schools and a day care centre.

Marshland proposed signalsViaStrada was engaged by Christchurch City Council to carry out a scheme design safety audit of a proposed signalised intersection on Marshland Road.

Site planViaStrada was engaged by Rotorua Lakes Council (RLC) to undertake a detail design stage road safety audit of the proposed shared use path on Ranolf Street between Arawa Street and Sophia Street.

Bealey Madras

ViaStrada was commissioned by Christchurch City Council to undertake a detail design stage road safety audit of interim works at the Bealey Avenue / Madras Street intersection.
