Practical implementation of performance objectives for traffic light signals

Abstract

This paper examines the practical implementation of objectives derived from research in respect of three colour road traffic light signals, with particular reference to NSW practice. The effects of varying a number of interdependent parameters are discussed, and it is shown that the component which most critically determines signal performance is the incandescent lamp. It is concluded that the performance objectives set by researchers can only nominally be achieved. Recommendations are made as to the need for further research and development work (a).
