To manage rapid growth and increasing traffic in Brisbane’s eastern corridor, TransLink undertook planning for a busway, a dedicated roadway for fast and reliable bus service. Translink’s challenge was to construct this infrastructure through established residential and commercial neighbourhoods, where community concern about bus exhaust was prominent.
Katestone modelled ground-level concentrations of pollutants including nitrogen dioxide, carbon monoxide and particles (PM10, PM2.5 and ultra-fine), as well as air toxics. We also showed how the busway could reduce greenhouse gas emissions for travel by up to 25 percent.
Katestone supported Translink at community forums. Illustrations such as a contour plot showing the air quality benefit of improvements to bus fleet composition made difficult conversations with residents easier.
Our expert analysis and advice to planners and the community helped manage the bus pollution and contributed to gaining approvals. Now, the busway is carrying approximately 7000 passengers each morning.
