Brisbane Traffic Study

In November 1987, VLC was awarded a study by the Brisbane City Council to update the Brisbane Transport Plan. This involved, inter alia, the total recalibration of travel forecasting models for the metropolitan area using VLC's proprietary software package VLC TRANSCEND. The "private travel" model was calibrated using a home interview survey of some 2,000 households, conducted by the Queensland Department of Transport in 1986.

An "external vehicle" model was calibrated using a series of roadside interview surveys conducted at the perimeter of the metropolitan area, and a "commercial vehicle model" was based on a survey of business establishments conducted by the Queensland Department of Transport in 1986.

In addition to evaluating alternative road networks for Brisbane, the study also assessed the impacts of five alternative land use scenarios for the city for the year 2006. The alternative land use scenarios considered the consequences of residential and employment decentralisation versus urban intensification and consolidation.

The resulting network and zoning system was also appended to VLC's Brisbane network model to provide more accurate forecasts of inter-city travel in the State's most important growth corridor. The model structure was framed within VLC's proprietary travel forecasting model VLC-TRANSCEND.
