Transportation Planning & Traffic Engineering

Share on:

Our transport and traffic team has extensive experience in planning, design and management of all facets of traffic engineering and transport planning projects.

GHD brings a fresh approach to integrated transport with an innovative, dynamic, highly motivated and enthusiastic team of traffic engineers and transport planners who harness a great depth of industry experience and knowledge.

Whether you require high level policy and strategic advice at the beginning of a project or detailed engineering advice at the design stage, you will benefit from the commitment and dedication of our people. We pride ourselves on staying informed of the latest industry thinking and trends through regular involvement in industry bodies, conferences and seminars.

We understand that transport needs are inherently linked to land use; the two cannot be understood in isolation. Our integrated team of transport and land use planners offer advice and solutions related to the entire system, rather than one item in isolation. Our solutions encourage active travel. We incorporate an understanding of economic and financial factors impacting on efficient freight movement, such as road versus rail freight options.

Public transport is becoming increasingly important in society. We are equipped to provide a way forward - from the specifics of bus route timetables through to the location and layout of new rail interchanges and associated track route alignments.

Our team offers services that include:

  • Active transport, bicycle and pedestrian advice
  • Demand management
  • Freight planning and advice
  • Integrated land use, transport advice and transport studies
  • Parking strategies, analysis and advice
  • Pedestrian simulation and traffic and transport modelling
  • Public transport infrastructure and service advice
  • Road safety audits and analysis
  • Strategic route planning and feasibility studies
  • Traffic engineering assessments and advice
  • Traffic impact assessments
  • Transport strategies
  • Travel behaviour change
  • Urban revitalisation transport advice

17 Mile Drive/Holman Highway 68/Highway 1 Roundabout Intersection ICE, Monterey, California, USA


As part of our integration with Omni-Means, GHD prepared a roundabout solution to improve the intersection of SR 68/SR 1 including access to 17 Mile Drive.

Existing delays at the location including various intersections operating at Level of Service (LOS) “D” and “F” during certain peak hours were becoming unsustainable and all intersections except SR 68/CHOMP were predicted to reach a LOS "F" by the year 2035. This meant that the EB approach on SR 68 during morning peak will have queues of 42 vehicles with similar queuing for the EB and WB approach during PM peak after 2025. In order to mitigate this, we prepared a transportation operations study to support the ICE process and presented the results of conceptual alternatives.

Interstate 5/Deschutes Road interchange improvements


As part of our integration with Omni-Means, GHD was engaged by the City of Anderson to study and develop interchange improvement alternatives, including the addition of a new northbound off-ramp, at the I-5/Deschutes Road interchange. The need to increase transport safety and efficiency is driven by large-scale development proposals in the vicinity.

This study included detailed traffic modeling, traffic operations analysis, and preliminary design alternatives. We also prepared a detailed Roundabout Conceptual Approval Report, Project Study Report, Project Report, and environmental approvals for the roundabout interchange. After the Traffic Impact Fee Program (also produced by GHD) was adopted by the City of Anderson and Shasta County in 2007, funding was secured in 2011 to undertake design phase 1 of the project, which includes a new off-ramp and 5-leg/2-lane roundabout for northbound traffic.

SR 99/Central Galt Interchange modification, Galt, California, USA


As part of our integration with Omni-Means, GHD has helped increase interchange capacity for the SR99. Aimed at solving deficiencies and accommodating planned growth within the City of Galt and the South Sacramento County region, the project is aligned with the respective adopted General Plans and the Transportation Concept Report (TCR).

The Central Galt Interchange is the primary access into the downtown area. Recent urban growth, and future growth projected by the General Plan, necessitated a solution to address a currently congested area. We provided 15 alternative design solutions for the selection committee to consider. The resulting design included the reconstruction of all four-interchange ramps, auxiliary lanes on SR 99 to the adjacent interchanges, and two new overcrossing structures.

Victoria Street West Cycleway


GHD is excited to work with AT on another important link in Auckland’s cycling network. The Victoria Street Cycleway (formerly called the Midtown Cycleway) will be a dedicated, physically separated from motorised traffic for the whole route running between the Beaumont Street intersection and the Hobson Street intersection along Victoria Street West.

The goal of the Victoria Street Cycleway is to create a continuous separated, safe, and attractive route to and from the city. Where practical, the cycle lanes will be physically separated from pedestrians with a small kerb. The Victoria Street Cycleway will be the first section of a larger midtown cycling connection. This connection will provide safe, separated cycling facilities between Victoria Park and the Auckland Domain, creating cycleways to and through the heart of the city centre from the west and the east.
