Cycling blackspots

We don’t like talking too much about cycling crashes, but we do believe the data should be used to help inform where infrastructure spending ought to be directed for maximum benefit.

Crash data from Queensland roads provides the locations of around 4,200 crashes involving cyclists which occurred in the Brisbane City Council area over the period 2001-2017. Mapping this data (red dots), and creating a heat map normalised for “crash risk cost”* provides some informative results:

There is an obvious black spot on Dornoch Tce at Highgate Hill, due to its popularity on “the River Loop” and the severity of injuries to cyclists who have crashed on this steep hill.

Aside from this, there is another glaring black spot for cycle crashes in the CBD – particularly concentrated along Adelaide St.

Annerley Rd is another well known hotspot, which will at least be partially addressed with the Woollongabba Bikeway.

Other high-risk locations would be only too familiar to regular riders, including:

  • South Bank at the intersection of Grey and Melbourne Streets.
  • Toowong (near Archer St);
  • Wynnum Rd at Norman Park (which Council has refused to address as park of the Wynnum Road Stage 1B works!), and through Morningside, Morningside Central, and Cannon Hill;
  • Stones Corner Roundabout and Old Cleveland Road through Coorparoo;
  • Lutwytch Rd, Windsor;
  • Sandgate Road, Nundah;
  • Bridge St, Albion (where work on the next stage of the North Brisbane Bikeway is overdue!);
  • Boundary St / Vulture St in West End;
  • Local problem areas at St Lucia, Indooroopilly, and Kenmore;

These are all locations where the BUGs have been asking Council (or as relevant TMR) to provide improved infrastructure, or high quality alternative routes. The map clearly shows where investment in cycling safety needs to occur.

The good news is that the overall crash numbers and crash costs have fallen slightly in the last two years – which could possibly be due to laws and education around minimum safe passing distances.


Looking at the days and times crashes occur, this isn’t just something that’s happening to weekend warriors; weekday crash rates are highest, and people travelling at peak times make up the majority of those getting hurt.


*Crash risk cost assessments apply a low cost to crashes resulting in only minor injuries; a higher cost to those requiring medical treatment; significantly more for those requiring hospitalisation; and a high premium on fatalities.

Here’s another view of the data, showing the cumulative costs of crashes involving cyclists each year from 2001 to 2017:
