The Department for Transport does not routinely collect or require data to be submitted on the use of speed cameras, although the Department's guidance does recommend that speed and collision data are collected by partnerships. However, the Department has an interest in the effectiveness of all road safety interventions and so from time to time requests evaluation work from delivery partners. For example, as part of two wider rural demonstration projects supported financially by the Department, Norfolk and Lincolnshire county councils are proposing to install permanent average speed enforcement cameras during the next year. Because these are demonstration projects the Department will receive information about the impact of these cameras alongside the other road safety measures being implemented locally.
