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:

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.

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.

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.

platform treatment at roundaboutThrough the iWay network and MoveIt school travel planning programmes, the Hastings District Council (HDC) has identified two corridors presenting barriers for people walking and cycling. HDC commissioned ViaStrada to review the safety and usability of seven roundabouts along these two corridors. While borne out of concerns for non-motorised users, the review also considers the safety of motorists.

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.

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.
