The Association of British Drivers (ABD) has welcomed the news that camera partnerships will have to publish speed camera data.

However, it is asking the Government to insist upon full and accurate data, after saying it has of experience of attempting to get raw data out of partnerships without success.

"Any data grudgingly released is invariably missing vital information or spun in a misleading fashion,” said ABD chairman Brian Gregory. “This cannot continue.”

The ABD calls for all camera partnerships to be forced to reveal the following:

• Full details of casualty and accident data per billion vehicle kilometres at each camera site five years either side of installation. This should include accident and casualty dates, exact speeds of vehicles involved, directions of travel and distance from camera location.

• Effects separated into fatal, serious injuries and non serious injuries, not KSI statistics.

• Other factors related to the incident, such as drunk, drugged, unlicensed and stolen vehicle.

• Other changes to immediate road layout and significant area changes during the previous 10-year period.

Gregory said: "Only when armed with the full information can the public see exactly what effect an individual camera has had. Of course, the raw data will also need to be trend adjusted i.e. casualties will have fallen everywhere over any recent 10-year period due to huge advances in vehicle design.”
