Bicycle riders needed for research data collection

Bicycle fitted with passing distance measurement device (PDMD)

We have now reached our desired participant number, and selected candidates will be contacted shortly. Intake is closed, however we kindly thank you for your interest in our study.


Are you a regular bicycle rider who rides predominantly on the road? Are you interested in being involved in a bicycle safety study that uses a bicycle-mounted device to measure the passing distance between cyclists and road vehicles? The Centre for Automotive Safety Research (CASR) at the University of Adelaide is collecting data on passing distances along Greenhill Road between Balhannah and the city (through 80 km/h speed zones) during the period April 12 to May 7 using a bicycle mounted device that measures the right-side passing distance between cyclists and road vehicles.

If you are a cyclist, you are invited to be a participant in the data collection process. If you are eligible to take part in the trial, a small device will be attached to your bicycle. The device will measure your GPS location and the distance to any passing vehicles. The device will not interfere with your normal riding. During the data collection period you should ride your bicycle in your normal way. You will be able to switch the device off if you do not wish to record certain parts of your ride. 

To be eligible to participate in data collection, you should:

  • Be aged 18 or older,
  • Be conversant in English,
  • Ride predominantly on public roads,
  • Store your bicycle in a secure place,
  • Be available to ride along Greenhill Road between Balhannah and the city (through 80 km/h speed zones) during the period April 12 to May 7,
  • Be willing to have a small electronic device mounted on your bicycle over the data collection period,
  • Be willing to have your regular cycling trips monitored, including information regarding your speed and location, which is obtained through the device’s GPS (it will be possible to turn the device off if you do not wish to have a particular journey recorded), and
  • Be comfortable using technology (you may need to recharge the device).

For further information about the study, you may contact the lead researcher Dr Jamie Makenzie (jamie.mackenzie@adelaide.edu.au or 08 8313 7329).

This study has been approved by the University of Adelaide Human Research Ethics Committee (Approval number H-2021-049)
