So speeding convictions rise each year yet the number of casualties is constant or falling?
Yes depending on how they are looked at. Deaths are more static over shorter periods, Statistics - seems 32% of speeding offences were in Essex in 22. Similar in 21.
23 and they get even higher. Maybe booking more looks to be a good idea. I recollect a really big increase in booking when a speed limit was applied to road works on the M42. Some one worked out the revenue. It was enormous. Accidents unlikely to figure.
Old style speed cameras. Generally they don't get reloaded with fresh film. Reason - not collecting enough revenue to cover the costs. Complaints that people slow down when they go past them. Interesting as usually it wont be by all that much. Oxford - you may find cameras that detect speed as a car is approaching as the newer methods do.
One of the death dips early 2000's may be due to the safety camera and other methods blitz. Fell out of favour as always placed where people were bound to be caught as unaware of the camera. Fine in some cases but OTT in others. My brothers case for instance. 30mph limits and he didn't notice the cameras and wont have been driving that fast. I've seen others similar. In Pembrokeshire. Local radio started telling people when the camera was out. Lots caught for being a bit over 30mph. One that got me. Motorway. Very early warning about a speed limit miles ahead. When I got there they had used the sort of signage usually used on side roads. i hadn't been exceeding the m way limit. Suddenly need to be doing 40, Now cameras are more likely to just come out from time to time. I assume to retain the deaths and reported accident numbers.
Last one I saw near me. First a dual carriageway that was mostly 40 for years and then changed to 30. It comes to an island which slows traffic down. One of the exits leads to a side road to retail centre. It's straight. Camera far into the distance checking for 30mph. Traffic light control on the entrance to the retail park also light controlled pedestrian crossing. People way more likely to see the camera van by the time they get to the retail park turn off. Sensible checking? I;d say it hardly caught any.
So they want another dip death and reported accidents. Will 20mph achieve that. I'd say it depends where they are. it would cause traffic chaos on some 30mph roads that are often congested any way. Even mess up flow when traffic lights are used to control that. Important for me as it means that I can easily get my car off the frontage onto the road and it's also important for users of the many side roads running off it for a large proportion of a day. At other times parts may choke up. I don't much care if they are doing 30 or 40. A speed indicator sign has reduced the 40mph merchants. Accidents at my end of the road are rather rare. As soon as anything like that happens the road chokes up. May also happen due to deliveries.
Personally I think the camera blitz has changed driving behaviour especially on motorways. Some 30 and 40 are easy to check but I seldom see signs that they are being. Maybe they are in Essex.
