Traffic engineering and transportation planning

Traffic engineering and transportation planning are some of our core skills.  We have significant experience in both the public and private sectors on a wide variety of projects. 

We are skilled at seeing the big picture as well as the detail, at thinking outside the square and at making sure that the traffic and transportation network is designed to be the best it can be.

You can rely on us for:

  • Strategic planning, investigation and reporting
  • Traffic engineering for road upgrade projects and new developments. We use urban design principles and provide transport solutions that supports mode shift and prioritises safety for vulnerable road users
  • Preparing and reviewing Integrated Transport Assessments for developers, land owners, local authorities with Waka Kotahi
  • Providing expert witness evidence at resource consent hearings, Environment Court hearings and Boards of Inquiry
  • Assessing developer contributions and heavy vehicle impacts
  • State highway reviews and studies
  • Public transport planning
  • Travel demand management planning
  • Road safety engineering and audits
  • Intersection modelling, vehicle tracking and swept path analysis, economic evaluation, feasibility assessments and funding applications. We have a Waka Kotahi recognised peer reviewer of economic evaluations
I would like to thank Karen and the team at Graymatter, for and outstanding job delivering the new roundabout at Hanlin Road. The project was very high profile, as it was outside the National Velodrome and St Peter’s School in Cambridge. Graymatter were involved from the beginning with project planning, and other activities needed to get funding approval. Graymatter led project and stakeholder workshops, and completed a comprehensive business case for the works. Graymatter also led investigations and completed the design work and contract documentation, and well as project supervision, and MSQA. Throughout the process the Graymatter team acted professionally and ensured tough questions were not avoided, and overall our stakeholders and partners enjoyed the positive collaborative honest and friendly approach taken. The end result is one the community is proud of, and looking at the project I can see many areas, where the inputs led by Karen and the team made a difference and ensured that value was added. Additional cyclepaths and bus access was able to be incorporated into the design. Karen also managed to keep all the parties working towards common agreed goals. The construction also was disrupted by COVID shutdown and Karen kept the project construction moving forward, and ensured that the all parties managed their own risks positively and colaboratively.   I would have no hesitation in recommending the Graymatter team for other works.
