There are still restrictions for motor vehicles by the Arsenal tube station, which -given the number of drivers who go past the signs of "diversion" and "traffic enforcement cameras"- I guess is becoming a source of income for Islington Council?
So, this mini-roundabout is probably ok given the circumstances. The close proximity of the junction with Holloway Road makes impossible to use traffic lights. This was proved during the road works when 3-way and 4-way temporary lights weere installed. Bad idea, really.
To have no horizontal signs, it's not a good idea either. This was the previous arrangement and didn't work that well.
The problem I see, is when coming from Holloway Road, the cycle lane does not follow the roundabout but is effectively diverting the cyclists to Benwell road where they have to give way to the traffic coming from the A103 and going towards it from Drayton Park Road. I'm not convinced with this.
And still, there is not yet a consistent plan for a route that would link with Finsbury Park, where the traffic lights and crossings are not adequate.
Time will tell, I suppose!
