The reason I ask this question, is because I read on USENET that the variable speed limit on General Holmes Drive at Mascot was set at 40km/h at midnight on a Saturday night for apparantly no reason. There is a speed camera on this road, and if the speed camera is linked to the variable speed limit (40k's) then I imagine the NSW State Government raised an exception revenue windfall that evening.
To make things worse, according to the RTA this stretch of road has no accident history
. It installed the camera because it claims the road is unable to be enforced by tradition means. This is the RTA's way of saying 'police cannot extract revenue from here, we'll do it with a camera'.
Have read of this site http://www.rta.nsw.gov.au/safety/c1521_c.htm
What blows me away is how they can justify cameras on my most used stretch of road, the M4 (both ways at the Cumberland Highway overpass.) Lets take east (city) bound. In the old days, when they openly the new section of road, it had a speed limit of 110. It's now 90. 1 death in 5 years. How do we know if they wasn't, say, a high speed chase gone awry? Speed of car thieves out that way, it's not inconceivable. 37 accidents, but only 14 injured. Compare that to Pacific Hwy at Herons Creek. 23 accidents, 32 injured. 38% injury rate on the M4 compared with 140% at Herons Creek. The speed camera at Herons Creek I can live with. The M4 camera is obviously a revenue raiser, as I would put my money on 90% of those accidents being heavy traffic rear-end bingles where speed has NO cause, only stupidity. Look at westbound on the M4, we have no deaths and a 31% injury rate, even less despite a higher 85th% than eastbound.
Seems to me that the only figure the RTA/NSW Gov. looks at is the 85th%, and decides if that can help maintain a regular income stream.
We need some sort of intelligent, organised campaign to rid the roads of this money-grabbing cancer. I feel sorry for Victorians, who have just had the speed tolerance reduced from 10% to 5%. Yes, that means you'll be pinched in a 60 zone for 64 and over now.
Excuse the EA S inspired post if you're bored with this stuff. At least look at the URL be educated as to the where abouts of speed cameras (other states should look theres up.)
