Now there are some users enrolled out there - (and you're all probably fed up already with replies to Peter Bull from other users joining) - an open question - to get the ball rolling! Recently we have mainly been installing MVDs with stopline loops on most of our schemes. On a current scheme we want to install an advanced (cycle) stopline (ASL) - but need system D loops (in association with speed discrimination). Do (you) other users set out your system 'D' loops 12, 25 and 39 metres from the vehicle stopline - or from the ASL? What is your rationale for whatever you do on this?
