A420: Plans for speed cameras on Swindon to Oxford route
The A420, which passes between Swindon and Oxford and has varying speed limits, has seen a number of dangerous road incidents, with 351 crashes taking place in the last few years. There was a crash between two vehicles on the road five days ago, and a lorry driver was also recently found guilty of killing a milkman in a crash there. Average speed cameras work by calculating the time it takes for a vehicle to travel along a set distance, instead of measuring the speed from a specific point in the road.
Oxfordshire County Council say the scheme "is still in development and at a very early stage". The spokesperson added that there were currently no further plans for more average speed cameras, but that other speed management projects were being considered under their Vision Zero speed management programme. Thames Valley Police and Crime[1] Commissioner Matthew Barber described the road as "one of the deadliest roads in the Thames Valley" and said the plans could help make an "entire route safe".

He also suggested using motorbike speed units instead of vans. There are currently no average speed cameras on roads in the Thames Valley, apart from on motorways. 
"We want to see less people dead and injured on the roads, whether they are driving, cycling or walking, so we strongly support Thames Valley Police and Oxfordshire County Council working together to look at the feasibility of average speed cameras on the A420. "We think that average speed cameras would be very suited to the job, because they can cover a large amount of road all day, every day. "They would work well on other roads that have a poor casualty record and a speed limit that is the same for a reasonable distance.
"There is no doubt that these cameras could make many people's lives a lot safer and better."
The scheme is still in the feasibility stage with the county council discussing funding arrangements with Thames Valley Police.
