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:

Photo of the completed junior road safety cycle track being used by children and families on a sunny Dunedin dayDunedin City Council engaged ViaStrada to develop concept plans for the layout of a learn to ride space that can be used to introduce new riders to a road environment, allowing riders to improve their personal safety and road awareness.

Pūtahi Park fountain lit up at nightViaStrada was commissioned by Whangārei District Council to undertake a road safety and network functionality audit post construction of the Putahi Park development.

Caversham tunnel entrance with vines and greenery each sideThe Dunedin Tunnels Trail Trust (DTTT) project is to provide a 15 km safe and user-friendly cycle and walking trail between Dunedin and Mosgiel. It includes two redundant rail tunnels at Chain Hills and Caversham built in the 1870s.

Bollard pictureWhakatāne District Council asked ViaStrada to provide a wayfinding signage plan for Whakatāne District's walking and cycling network. Its focus: how can we help people (and visitors) navigate their community?

queued traffic In order to optimise the function and safety of the route by mode and time of day, ViaStrada (with Aurecon as a sub-consultant) conducted site audits at eight intersections; researched the planning and engineering context; identified capacity constraints; analysed crash data and safety issues, considered modal requirements; identified engineering and operational improvements with costings.

Manawatu River BridgeViaStrada has been commissioned by the Palmerston North City Council (PNCC) to undertake a NZ Transport Agency (NZTA) compliant scheme stage safety audit of the Manawatu River pedestrian & cycle bridge (since named He Ara Kotahi).

Cycle laneViaStrada has been engaged by Auckland Transport to provide concept designs to address outstanding issues from the Puhinui Road Post Construction Safety Audit.

intersection viewViaStrada staff have safety audited the proposed traffic signals at the intersection of Main North Road with Belfast Road at various project stages. The junction is proposed to change from a T-intersection to a cross intersection to give access to a residential development.

Contra-flow cycle laneViaStrada was commissioned by Auckland Transport to conduct a post construction safety audit of the Federal Street contra-flow cycle lanes. The Federal Street project runs between Victoria Street West and Wyndham Street and between Swanson Street and Fanshawe Street. St Patrick's Square (to the east side of St Patrick’s Cathedral) between Swanson Street and Wyndham Street was also assessed, based on site visit observations.

Guppy / Meeanee intersectionIn August 2018, ViaStrada prepared a scheme report assessing capacity and safety issues (including sight lines to oncoming traffic) for the signalised Guppy / Meeanee intersection. Subsequently a detailed design of the preferred option was developed.
