From the available information posted, it doesn't make any reference to traffic volumes, hence my issue about the validity of any research.
It that case - you have a point. There is an argument (unproven) that cameras cause drivers to take other routes which both decreases traffic on the camera route and increases it elsewhere. The relationship between traffic volume and accidents is complex anyway...
Speed cameras are often placed on wide, straight roads were people can be tempted to do a little more than the posted limit. Especially if there's a hill which might help to speed things up.
So car drivers are then tempted to make their journeys on other, perhaps less suitable and potentially less safe routes, perhaps?
So the "Safety" Partnerships might be displacing volumes of traffic and thus decreasing the safety of road users and others?
