Annual performance indicators of enforced driver behaviours, 2002
The Centre for Automotive Safety Research at the University of Adelaide was commissioned by Transport SA to
produce a report quantifying the effects of selected enforced driver behaviours: drink driving, speeding and restraint
use, in South Australia for the calendar year 2002. The level of random breath testing (RBT) has increased
substantially such that the annual average rate of testing was 2 tests for every 3 licensed drivers in 2002. An
inverse relationship between detection rates and publicity expenditure suggests current publicity campaigns are
supporting enforcement operations.
Overall, speeding detection rates in 2002 decreased, especially speed camera detection rates. However, speeding
detection rates were heavily influenced by police enforcement strategies and practices. Rural speed surveys
indicated that the mean free speed decreased from 2000 to 2002 on 100km/h roads but showed no meaningful
change on 60km/h and 110km/h roads each year.
Determining the effectiveness of restraint use enforcement was very difficult because no specific restraint
enforcement campaigns were undertaken. In the absence of available restraint enforcement details, the number of
restraint related offences committed annually was used to provide a rough estimate of enforcement activities.
Reasonably consistent observational surveys were useful in providing an indication of restraint wearing rates over
time in a number of regions. The surveys indicated that both metropolitan and rural wearing rates increased in 2002
to a level of 96 per cent, just above the national target of 95 per cent.L.N. Wundersitz and A.J. McLea
Demographic Faultlines and Creativity In Diverse Groups
Despite the oft made argument that demographic diversity should enhance creativity, little is known about this relationship. We propose that group diversity, measured in terms of demographic faultlines, affects creativity through its effects on group members’ felt psychological safety to express their diverse ideas and the quality of information sharing that takes place across subgroup boundaries. Further, we propose that the relationship between faultlines and creativity will be moderated by task interdependence and equality of subgroup sizes. Finally, we provide suggestions for how organizations can establish norms for self-verification and use accountability techniques to enhance creativity in diverse groups
