This report outlines the findings of a study which has evaluated the new regulation introduced in western Australia in June 1975 determining right-of-way obligations of drivers at uncontrolled three-way intersections. Under the new regulation drivers on the terminating road must give right-of-way to all drivers on the continuing road. The study showed that prior to the new regulation the majority of drivers were already adopting the major/minor road concept. This driver behaviour pattern was found to be strengthened by the new regulation. On the basis of this finding it was concluded that the new regulation has been beneficial in that it has reduced driver hesitancies and, in addition, provided regulations that are self-reinforcing. A study of 200 intersections provided no statistically significant changes with respect to road accidents. (A) /TRRL/
