Nope, they've got old-skool proper green men signs on poles that everybody can see. Might also have the new and rubbish ones also, but never look down that far.
Most dangerous road in Brighton?
Depends who you mean it's dangerous FOR.
For pedestrians, I'd nominate:
1. The pedestrian crossings around the Clock Tower
2. The pedestrian crossings around Fiveways 'village'
3. The pedestrian crossings at the bottom of London Road by Boots
At all three...
