Recent work in Canada on the development of traffic conflicts techniques.

Based on earlier work and previous studies of post encroachment time (pet) as a measurement of traffic conflict the road safety branch of transport Canada does not have much confidence that pet would prove to be a useful tool, either for diagnosis of accident problems or evaluation of countermeasures. Further application of the pet measurement techniques to larger samples of locations would be required to verify this; but the department of transport has not found there to be any concrete interest in developing and using the techniques. It appears that formal measurement and analysis of conflicts is still not used in Canada. For the covering abstract of the conference see IRRD abstract no 265671.
