New safety camera locations are considered on a site by site basis. The Casualty Reduction Partnership considers the accident history, speeding problem and community concern along each stretch of road.
Once a stretch of road has been deemed suitable for camera enforcement, the camera is positioned carefully to minimise adverse environmental effects on nearby residential properties - while at the same time ensuring that it is highly visible to road users. Locations must also meet all operational and health and safety requirements.
There are three types of camera in use - fixed speed, mobile speed and red-light cameras. At present there are approximately 101 fixed speed cameras, six mobile safety camera vans (which operate seven days per week) and 26 red-light cameras in Essex, Southend-on-Sea and Thurrock.
