Enforcement

Dorset Road Safe is an organisation made up of police and partner agencies who come together for the shared purpose of reducing the number of casualties on our roads.

We are committed to making strides towards our shared target of bringing about a 40 per cent reduction in those killed and seriously injured on Dorset roads by 2020.

Working together is integral to developing innovative solutions that directly address the causal factors behind road fatalities.

6 Strategic Priorities:

  • Pedestrian and cyclist casualties, particularly in urban areas
  • Better Road safety Education and Training for Children, Learner and Young Drivers
  • Motorcycle casualties, particularly young scooter riders and adult riders on larger bikes.
  • Rural road KSIs
  • Careless or dangerous road user behaviour
  • Illegal and inappropriate speed

Speed Enforcement

We operate fixed, mobile and red light cameras throughout Dorset at locations where there is a history of injury collisions, where there is a known speeding issue, where there is known non-compliance of red traffic signals, or where we have received speed complaints from members of the public.

Speed limits are set by the local council. It is the responsibility of the police to enforce the speed limits. 

In addition to enforcing the law, safety cameras are one of the many methods we use to try and reduce road traffic casualties. Further useful information about road types and the National Speed Limit can be found by visiting the Alliance of British Driver's website.

Types of Camera Used

In Dorset we operate four types of camera units:

  • Gatsometer Type 24
  • Gatso Red Light
  • Kustom LaserWitness Lite
  • Concept II Laser

These cameras have been Type Approved by the Home Office for speed enforcement in the UK, they are calibrated on an annual basis, they are accurate to +/- 1mph and are checked before and after any camera enforcement takes place.

We use the Gatsometer type 24 camera. The fixed camera housings have a grey pole with a bright yellow box on the top and inside the yellow box.

The camera uses a radar to detect the speed of a vehicle. When a vehicle crosses the radar beam at excessive speed, it activates the camera. The camera takes two photographs of the rear of the vehicle at an interval of 0.5 seconds.

White lines painted on the road surface provide an independent way of verifying the speed reading recorded on the film. The first picture is compared against the second picture to see how many lines the vehicle has crossed between the two photos. The secondary markings are a set distance of five feet apart and this tells us how fast the car was travelling.

We use three different types of camera for mobile enforcement: the Laser Concept II, Kustom LaserWitness Lite and mobile Gatsometer.     

The Kustom LaserWitness Lite and the Concept II cameras are set up in the camera vans with the camera pointed out of the van at passing vehicles.

The mobile Gatso is the same camera unit which is used in the fixed housings, but can be used as a mobile device which is set up on a tripod by the side of the road.

The objective of a red light safety camera at a signal-controlled junction is to reduce the number of collisions caused by drivers’ non-compliance with a red light signal. A red light safety camera will only activate when the red light is illuminated.

The red light safety cameras are linked to two induction loops set in the road, one just before the stop line and the second a short distance past the stop line.

When a vehicle moves over the first loop, the sequence is initiated. If the vehicle continues to cross the second loop (past the stop line) the camera will take a photograph, followed by a second photograph one second later. The photographs will record the date, time and speed of the vehicle. It also records the amount of time elapsed since the red light was illuminated and lane identification can also be recorded on the film.
