Abstract
INJURY ACCIDENT DATA FOR A SAMPLE OF NEW ZEALAND URBAN INTERSECTIONS WERE ANALYSED, LOOKING FOR AN INCREASE OR DECREASE WHICH COINCIDED WITH A CHANGE IN CONTROL. INCREASES OR DECREASES WERE ALSO LOOKED FOR IN CERTAIN TYPES OF ACCIDENTS AND IN ACCIDENT SEVERITY. THE CONTROL CHANGES CONSIDERED WERE FROM GIVE WAY SIGNS, STOP SIGNS AND NO CONTROL TO SIGNALS AND SMALL ROUNDABOUTS AND ALSO FROM NO CONTROL TO GIVE WAY AND STOP SIGNS.(Author/publisher).
