STUDY DESIGN FOR THE EVALUATION OF THE EFFECTIVENESS OF MITERS - TYPE PROJECTS: SUMMARY

This summary report prepared by Nicholas Clark and Associates briefly describes the design phase of a study to evaluate the safety effectiveness of certain minor traffic engineering and road safety projects undertaken in Australia. A review was made of sources of data available on accidents, traffic flows and minor traffic engineering improvements for road safety implemented in the states of Australia. It was concluded that the major data constraint relates to accident data and that south Australia and western Australia are presently the only states with data bases in an immediately suitable form for the proposed evaluation. A methodology was developed and recommended for the evaluation phase, based on the principles of the before- and-after study. Care was given to resolution of problems arising from changes in site exposure and changes in secular trends of accidents. A trial analysis was conducted for some intersection signalisation projects undertaken in adelaide in 1975/76. The feasibility of the proposed methodology was demonstrated and some preliminary results established concerning the safety effectiveness of these projects. (TRRL)
