Traffic & Transportation Engineering

Traffic & Transportation Engineering

BBO’s traffic and transportation engineering team provide a vast range of skills and experience to deliver all services required within this professional discipline.

Transport Planning – transportation advice for rezoning and changes to district plan rules, structure plans, and master plans for a range of clients including local authorities, land-use planners, land developers, architects, civil engineers, and service providers. Our inputs facilitate the integration of sustainable transport concepts and solutions into the client’s masterplan objectives, resulting in well-functioning urban environments.

Transportation / Traffic Assessments – the preparation of Integrated Transport Assessments (ITA) and Traffic Impact Assessments (TIA) for all types of developments that require rezoning and/or resource consents. These assessments identify the effects of a new development where transport demand is generated on the surrounding transport network and identify any mitigating measures that may be required. They often involve intersection performance analysis, pedestrian and cyclist accessibility and safety assessments, parking provision, access arrangements, internal site circulation, and liaison with the relevant transport authorities.

We also provide expert witness traffic and transportation engineering evidence at Local Authority and Environment Court hearings.

Transport Modelling – we use industry recognised software such as PTV Vissim (micro-simulation), and SIDRA Intersection, and LinSig to test the capacity and performance effects of proposed road network improvements, and to study the extent of impacts of land-use developments. 

  • PTV Vissim: a detailed traffic micro-simulation software package, used to accurately model all modes of transport interaction in multifaceted urban network environments.  It is highly valuable for visually demonstrating traffic behaviour in complex scenarios including the effects of queues, lane changes, weaving, and merging. 

  • SIDRA: an analytical software package for modelling traffic at signal, give-way, and roundabout intersections, as well as access ways to roads.
  • LinSig: software for assessing closely spaced signalised intersections, or signalised roundabouts.

BBO’s traffic and transportation team also undertake the analysis of large-scale development transport effects on the wider network, using scenario testing in the Waikato Regional Transportation Model (WRTM).

Road Safety Audits and Studies - a formal and structured process for the assessment of the safety aspects of road projects. Our fully accredited road safety engineers are experienced in all stages of road safety review including preliminary design, detailed design, and post-construction. Senior members of our team have completed the Waka Kotahi NZ Transport Agency Safe System Engineering Workshop.

Services provided include safe system road safety design, road safety audits, walking and cycling safety in design, and crash reduction studies for both urban and rural networks. 

Other traffic and transport engineering related professional services include:

  • Traffic signal crossing and intersection design
  • Roundabout, traffic signal, give-way, and stop controlled intersection capacity assessments
  • Transportation/traffic model peer reviews to NZ industry guidelines
