Camera Types and Enforcement
Camera speed enforcement within Lancashire falls into two categories, both of which use different equipment to detect the speed of motorists. The two types are MOBILE and STATIC enforcement.
Mobile Enforcement
The mobile enforcement consists of 10 technicians who work from divisions throughout the Lancashire Area, and have at their disposal 8 fully liveried enforcement vans.
Laser is used as a means of detecting vehicle speed. More detailed information on the devices can be found on the manufacturers website at www.teletrafficuk.com .
The primary evidence in a speeding case is the opinion of the operator as to the speed of the vehicle. Once the operator has formed the opinion that the vehicle is speeding, then they will utilise the laser equipment to confirm their estimation of the speed.
All the laser devices are calibrated by the manufacturer every 12 months as required by both the manufacturers and the ACPO guidelines. Example copies of the calibration certificates are shown below.
All the mobile operators are trained and authorised to operate the equipment. There are no untrained technicians or un-calibrated speed enforcement devices used within Lancashire.
Mobile enforcement is carried out on sites which are designated as problem sites owing to the number of Road Traffic Collisions or as a result of community concern. All the sites have been risk assessed as to their suitability for use, and are authorised by the relevant Authority for that area.
When mobile enforcement is being carried out, the vehicle or operator will be in a highly visible position, and if the operator is enforcing outside the vehicle, he will be wearing full class ‘A’ high visibility clothing.
Above is an example of the mobile speed detection photograph.
Static Camera Enforcement
Static camera enforcement within Lancashire is almost exclusively carried out by fixed cameras within the yellow camera housings situated at the side of the road. There are almost 300 static camera sites within Lancashire, which may be in use at any given time.
The equipment used within the static cameras is a GATSOMETER Type 24 radar with AUS type 35mm wet film camera and flash gun.
More information on the Gatso model AUS can be found at www.gatsometer.com
The white lines on the road surface are secondary check marks and are a specified distance apart. Once a vehicle has been identified as breaching the set speed threshold the camera will be triggered to take two photographs. The first will be the evidential photograph with the speed recorded on the Data bar, the second will be 0.5 seconds afterwards and will allow the viewing officer to confirm the speed of the vehicle by calculating the distance the vehicle has travelled between the photographs in the 0.5 second. It is this area where the enforcement differs from the mobile enforcement in that the fixed site is un manned and requires the second photograph for corroboration of the vehicle speed.
