THIS SCEPTRED ISLE|
Why does West London have "Chiswick Roundabout", and the "Hogarth Roundabout", but a couple miles north is the "Hanger Lane Gyratory System"? Surely it used to be "Hanger Lane Roundabout"?
What's the difference?

- The BBC website www.bbc.co.uk/dna/h2g2/A303346 reports that "when such a rotary intersection grows too big for its boots, acquiring multiple lane markings and complex filtered multiphase traffic lights, the basic roundabout priority rules break down, so the powers that be have decided that these things must be called something else. Evidently the term 'gyratory' won the day." By this definition, any roundabout that includes traffic lights ought to be known as a gyratory system.

- Both the Chiswick Roundabout and the Hogarth Roundabout have multiple lanes and traffic lights, so nobody has explained the difference, except they are both on the A4 and the Hanger Lane Gyratory System is on the A40 so I suppose the difference is 36.
