Closed after a driver hits a beacon and drives off :roll:

A Driver couldn't cope with a pedestrian crossing.... says more about the driver than the roundabout design!

You're obviously reading between the lines and deciding what you think I meant!
There is no between the lines I wasn't pointing the finger at anything.I was merely stating a fact.....ie "Not a good start" :wink:


Not my intention, it was a comment on the individual driver, following comments locally

So, heading north from the hospital, you now encounter 3 different designs of roundabout one after the other. So, a chance to see which design works best, except to do the experiment properly you would ideally want to randomize the sequence in which they are encountered to overcome "order effects"!

Or you could see how they perform in terms of safety on crashmap:
https://www.crashmap.co.uk/
Search for Perne Road Cambridge, select vehicle type as pedal cyclist:
This shows
16 cycles injured at Cherry Hinton Road,
8 at Queen Ediths Way (the one that has just changed) and
2 at Radegund Road the (one that was converted to continental geometry in 2014)
Now select the years 2009-2013 you see:
13 at Cherry Hinton Road (much the same),
8 at Queen Ediths Way (exactly the same) but
14 at Radegund Road the (before it was remodelled)

It looks like the compact geometry at the Radegund Road / Perne Road is protecting two Cambridge cyclists each year from getting hurt.
