OR 5: Effect of Seat Belt Design Rules on Wearing Rates

Summary

Through the Australian Design Rule program, action has been taken to make seat belts more convenient, more comfortable to use and more effective in accidents. Inertia reel lap sash belts for front outboard positions and improved upper anchorage locations for all outboard-seating positions became compulsory for all passenger cars and derivatives manufactured on or after 1 January 1975. These represent the most recent major efforts to improve restraint system in these vehicles.

OR 1: Rules of Precedence at Intersections: An Examination of Alternatives for Australia

Summary

The paper examines the principles underlying the approaches adapted to the regulation of traffic at intersections in the United Kingdom, the United States of America, Australia and New Zealand and comments upon their relevance to local conditions. It is argued that adoption of offside priority (giving way to the right whilst driving on the left) rather than either of the alternatives (giving way to the left or major/minor roads) has proved increasingly inappropriate to modern traffic conditions as well as detrimental to urban amenity.

CR 05: The effectiveness of Australian Design Rule 22 for head restraints (1979)

Summary

As introduction, the report describes Australian Design Rules 22 and 22A requiring head restraints to be fitted to driver and front left seats of all new cars in Australia from 1972 models onwards. The effective heiqhts of these restraints are discussed, as well as the nature of whiplash injuries which they are designed to prevent. Other studies of head restraint effectiveness are reviewed. Data on 1974–75 claims to the Motor Accidents Board in Victoria for injury compensation are then analysed to evaluate the effectiveness of ADR 22.

Provisional registration

The parties to a conference agreement or a representative of these parties may apply for provisional registration of a conference agreement or a varying conference agreement under Division 6 of the Competition and Consumer Act 2010 (the Act). Provisional registration involves the publication of details of a conference agreement in a public register and requires parties to negotiate with and provide information to the designated shipper body.

CR 10: Development of breakaway utility poles (1979)

Summary

An investigation of alternative schemes for in-situ modification of existing conductor-carrying and luminare timber poles was undertaken using a 1:7.38 scale model of the vehicle/pole/cable system. A simple pole modification scheme which achieved a significant reduction in collision severity while maintaining the integrity of the conductors was developed.

CR 09: Study design for the evaluation of the effectiveness of MITERS—type projects—summary (1979)

Summary

This Summary report 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.

CR 02: Collisions with utility poles—Summary report

Summary

This report summarises the objectives, methodology, findings and recommendations of a study of collisions with utility poles. In a survey of accidents, information on site characteristics and accident severity was obtained. Randomly selected samples of sites and vehicles provided control information. An accident-predictor model which identifies accident risk on the basis of site measurements has been derived. The mode was used in conjunction with estimates of the costs of accidents to show that a number of remedial treatments are warranted.

CR 04: The effect of seat belts on minor and severe injuries measured on the abbreviated injury scale (1979)

Summary

Following the implementation of compulsory seat belt wearing legislation in Victoria in December 1970, the Royal Australasian College of Surgeons established a survey to collect detailed injury and crash data from car accidents in that State. An analysis of the affect of seat belt wearing on severe injuries sustained by car occupants during the first two years of the survey was reported by Cameron and Nelson (1977). Minor injuries were ignored in that analysis.

CR 06: Appraisal of the existing traffic accident data collection and recording system—South Australia (1979)

Summary

Traffic accident data collection in South Australia has been appraised with the intention of answering two questions: What can reasonably be expected of the mass accident data system, and what improvements could be achieved by alterations to the system or to the demands made of it? Dummy accident reports, compiled by a Survey Team attending accidents in metropolitan Adelaide, were compared with computer accident records prepared by the Australian Bureau of Statistics using police accident reports edited and coded by the South Australian Highways Department.

CR 07: Frontal impacts and the effect of Australian Design Rules 10A and 10B for steering columns (1979)

Summary

Australian Design Rules (ADRs) 10A and 10B are aimed at reducing injuries to drivers who strike steering columns. ADR 10B is also aimed at limiting rearward displacement of steering columns in frontal collisions. Information from the Royal Australasian College of Surgeons Pattern of Injury Survey of crashes and injuries in Victoria was analysed to measure the effect of the ADRs on injury severity. The problem that there were relatively few drivers of ADR 10A or 10B cars in the data was solved by vehicle and crash circumstances.
