GHD relies on DataFromSky in Australia

Our team at GHD was very impressed with the DataFromSky software platform, the way in which data was processed and the rich outputs that the software provided. There is a huge range of visual outputs that are fantastic to present to stakeholders. DataFromSky team was always very helpful in responding quickly to our queries and we were impressed with their professional approach

Melbourne menší 1


On behalf of the Victorian Department of Transport (VicRoads), GHD undertook an investigation of gap acceptance at roundabouts and signalised intersections in Melbourne, Australia. For their analysis, they chose to utilize DFS Traffic Survey.

The two roundabouts assessed in this study were multi-lane roundabouts and the signalised intersection was a major hub with heavy traffic volumes.

Previous studies around gap acceptance relied upon manual observations of video data. However, GHD decided to use UAVs and DFS Artificial Intelligence software instead so they could get a robust dataset not prone to human error. It also allowed them to calculate accepted and rejected gaps at the investigated sites easily.

With this toolset, GHD specialists were able to assess the behaviour and gap acceptance of vehicles at the intersection/roundabout with great accuracy. DFS TrafficSurvey also provided them with detailed information disaggregated into various vehicle types, data about circulating traffic volumes and follow-up headways. 

They further analyzed the data with both our software and advanced spreadsheet techniques. The finished traffic study was then handed on to VicRoads, which used it during the preparation of new Traffic Modelling Guidelines.
