Adelaide's northern suburbs have some of the worst intersections in the city when it comes to road crashes, according to data released by the RAA.
Seven of the 10 intersections which recorded the highest number of crashes leading to injury in the last five years were located in the northern or north-eastern suburbs.
But despite a major redesign in 2013, Britannia roundabout on the CBD's eastern edge remains the location with the most casualty crashes.
From the start of 2016 to the end of last year, 43 incidents which left motorists with minor or serious injuries were recorded at the two roundabouts at the intersection of Fullarton, Wakefield and Kensington roads and Dequetteville Terrace.
RAA spokeswoman Hayley Cain said almost three-quarters of Britannia roundabout crashes involved T-bone collisions.
"There's also some speed involved there now because some of these collisions are happening when there isn't peak hour traffic, as well as when there is," she said.
Driver inattention, speed and road quality were all deemed factors contributing to high numbers of incidents at intersections in the northern suburbs.
Stebonheath and Womma roads in Edinburgh North recorded the second highest number of crashes, with 41 casualty incidents, followed by Peachey and Curtis roads in Smithfield Plains with 34.
"There's a lot of development going on there," Ms Cain said.
"Additionally, the roadways up there are quite congested anyway as people move around — there's a lot of population out north."
Of the crashes recorded at the top 10 intersections identified from state government data, rear-end collisions were the most frequently seen — in 36 per cent of incidents — followed by right turn (31 per cent) and right angle (28 per cent).
'It's just madness at times'
For two years, Dean Calvert's IT business has operated in a building which overlooks Glynde Corner.
The junction of Payneham, Glynburn, Lower North East and Montacute roads has been the site of 28 casualty crashes since the start of 2016, placing it seventh on the intersection crash list compiled by the RAA.
"When it really rains, I'll just stand up here and watch what's going on. It's just madness at times," Mr Calvert said.
He believed the poor surface and complex design of the intersection led to problems.
"Every few weeks there's got to be something," he said.
"I've had staff members report back to me there's been another accident out the front there, or another near-miss or hearing horns going off."
The intersection is 300 metres from Road Safety Minister Vincent Tarzia's electorate office.
"It's safe to say that I probably drive through this intersection every single day, " Mr Tarzia said.
"We know that the east and the north-east of Adelaide is a great place to live. And as density does increase over time, of course we will need to look to upgrade intersections."
Work planned for some problem sites
While acknowledging state and federal government plans to improve some of the trouble-plagued intersections, the RAA argued more could be done to improve safety at known crash locations.
"There are always ways in which we can do things better — and most of the time that takes money," Ms Cain said.
Mr Tarzia said the government had already committed $500 million to intersection upgrades.
Of the list pulled together by the RAA, he said improvements were planned or underway at four sites identified by the peak motoring body.
"It's also a reminder that people have got to do the right thing on our roads.
"They can't be driving while distracted. They've got to be sticking to the road rules."
