Kamera perangkap laju sebabkan lebih banyak kemalangan



Kajian di negara maju iaitu di United Kingdom mendapati sistem kamera perangkap laju hanya mengurangkan kadar kemalangan di tempat yang di pasang kamera, tetapi meningkatkan kadar kemalangan di tempat yang tidak di pasang kamera. Akibatnya kadar kemalangan keseluruhan negara tersebut telah meningkat.  Di negara kita juga terbukti apabila terdapat beberapa lokasi di lebuhraya sering berlaku kemalangan dalam tempoh beberapa hari. Begitu juga kita dapati bas dan lori sering melebihi had laju 90 km/j apabila berada di lebuhraya.

SPEED CAMERA SIGNS A HAZARD

Signposted speed cameras may actually make roads more dangerous, according to experts.

Road safety advisor Ray Shuey told ninemsn that speed cameras have a positive local influence but signposting them could make other areas of the road network more hazardous.

The warning follows the revelation of a 25 percent dip in speeding fines in NSW since a trial of mobile speed cameras in unmarked police vehicles was abandoned in 2004.

"If you analyse the traffic flows near overt speed cameras along the Hume Highway on the NSW side, you'll see that many motorists break before the camera zone and accelerate afterwards," he said.

"It does reduce crashes in this location but then you have to consider the collision displacement effect – has this strategy really reduced crash rates?"

Mr Shuey, a former Victorian assistant police commissioner, cited a 2003 study showing that accident blackspots in the United Kingdom monitored by overt speed cameras reported a 30 percent reduction in collisions.

However, the overall road fatality rate in the UK rose by two percent that year. His concerns are shared by Professor Jack McLean, director of the Centre for Automotive Safety Research at Adelaide University.
