Abstract

Accident reports from 41 public schools and a questionnaire survey in a primary school confirmed high accident frequency at right-angled corners in corridors. A hypothesis was thus formulated that the rounding of corners, if given a sufficient radius, would significantly reduce head-on collisions, and was tested through video research of 203 flow lines in the same primary school and 608 flow lines in a series of full-sized models. The radius of 2.6 meters, which reduced the probability of corrision to 13 per cent, was recommended as a guideline for collision-free corridors.
