Executive Summary
I was somewhat hoping that the 23 years of data would show some impact from the improvements that have been made in passive safety across the last three decades but the data doesn't really depict any significant changes for the better.
The situation is somewhat better for dynamic safety initiatives as there is a marked decrease (about 55%) in the total number of accidents but this does not seem to correlate with an improvement in either the death or serious injury data.
In simple terms we are having less accidents but managing to kill about the same number of people and while we are seriously injuring less people in raw number terms, the drop is only about 12% so the rate has actually increased.
The legislators will probably be pleased to note that the biggest drop in accidents has occurred in the suburbs (about halved) lending some credence to the speed camera regime but as this has not coincided with a drop in fatalities and serious injuries it should be cold comfort to them. Conversely, rural accident rates are largely unchanged in raw number terms.

Firstly thanks for putting the graphs all together.
I am somewhat mystified by your interpretation that a graph displaying data showing the number of accidents etc as being constant from 1987-2009 doesnt represent an improvement?
In the same time the population has increased by over 25%, consequently if the line on the graph is flat that represents a real drop of 25% over the 23 year period, any line actually trending downwards represents a greater than 25% change.
Perhaps that will change your interpretation of how effective certain measures are.
Personally I think many of the conclusions you draw from the data are flawed, but anticipate this thread is not for the purpose of debating these ideas.
Likewise, I think that you are better off just supplying the information and leaving people to make their own decisions about what the data shows, or perhaps to start another thread where you can raise issues relating to it.
