PLEASE NOTE: This video was taken ‘on the streets’ and does not necessarily reflect safe cycling behaviour. On your bike? Then get online and sign up for UNSW?s Safer Cycling Study, launched this week. The past few years have seen an explosion in the number of cyclists on Australian roads. It's estimated that in metropolitan Sydney alone about 7000 cycling trips are made every weekday. With more people choosing to commute by bike, the debate is on as to the best way to safely accommodate the mix of bikes, cars and pedestrians. Dr Ros Poulos from the University of New South Wales is heading the Safer Cycling Study. She's hoping to enlist 2000 cyclists from across the state to gather information about cycling habits, with a particular regard to safety.   Interested in joining the survey? Check out the Safer Cycling Study website under "Related Links" at right. Dr Ros Poulos (public health physician) from the University of New South Wales is the lead Chief Investigator on the Safer Cycling Study. Other Chief Investigators involved in the study are Dr. Julie Hatfield (psychologist), Prof Raphael Grzebieta (engineer), A/Prof Andrew McIntosh (biomechanicist) from UNSW and Prof. Chris Rissel (epidemiologist) from the University of Sydney. This research is supported under the Australian Research Council’s Linkage Projects funding scheme in association with the RTA, Bicycle NSW, Sydney South West Area Health Service from NSW Health, and Willoughby City Council.
