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:

roundabout approachPalmerston North City Council (PNCC) engaged ViaStrada to undertake post construction road safety audits of a number of recently completed roundabout upgrades at city intersections.

mapViaStrada was contracted by Whanganui District Council to design or retrofit five sets of signalised intersections so that the Te Tuaiwi pathway could be incorporated. From concept to delivery, ViaStrada took charge of all project stages to detailed design.

Wigram Skies mapViaStrada was engaged by Ngai Tahu Property Ltd to undertake a post construction road safety audit including day and night time site inspections, of a large residential subdivision in Christchurch.

Blenheim roundabout conceptViaStrada was commissioned by the NZTA to identify up to five intersections with the highest recorded crashes, investigate causal factors and propose concepts to address the cycle crashes. In addition, an assessment of cycling issues along four corridors was asked for.

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.

Augustine Halswell designViaStrada was commissioned by Christchurch City Council to undertake the scheme stage and detail design stage road safety audit of a proposed signalised intersection on Halswell Road in Aidanfield.

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.

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.

Contra-flow cycling signAuckland Transport commissioned ViaStrada to develop and investigate some options for providing contraflow cycling on three suburban one-way streets. In the absence of current design guidance or practical examples for New Zealand, a “first principles” approach was taken to consider all possible ways to provide for contra-flow cycling on the streets in question.
