Brisbane Transport Noise Corridor Overlay Categories

A 2014 Brisbane City Plan overlay map delineates transport noise corridors for state-controlled roads and the rail network. The dataset categorizes areas into five noise level bands (e.g., Category O: <58 dB(A) to Category 4: >73 dB(A)) based on Queensland Development Code MP4.4. It is maintained by Brisbane City Council and was last updated in March 2026.

Use Cases

• Model property development restrictions by analyzing 'State designated noise corridor' categories against zoning data.
• Assess population exposure to high-decibel areas by mapping residential parcels against 'Category 4: Noise Level > 73 dB(A)' zones.
• Compare noise mitigation requirements for 'State-controlled road' versus 'rail network' corridors using their distinct dB(A) category thresholds.

Strengths

• Provides structured noise categories defined by the Queensland Development Code MP4.4.
• Distinguishes between mandatory and voluntary areas for state-controlled road corridors.
• Offers separate, detailed noise level bands for rail network corridors.

Limitations

• No quantitative row or feature count is provided, limiting assessment of spatial granularity.
• The underlying geometry or spatial data files are not described, requiring users to locate them separately.
• Primary data is linked to a 2014 plan document, which may not reflect the most current land use or infrastructure changes.
