[TCUG] Re: Loops and ASL's - an open question!

At the risk of degenerating into a legal (rather than a traffic control) 
talking shop, I should point out that actually, The Highway Code is 'not' in 
itself a legal requirement - as the Highway Code itself states:

"A failure on the part of a person to observe a provision of the Highway Code 
shall not of itself render that person to criminal proceedings of any kind, but 
any such failure may in any proceedings (whether civil or criminal,and 
including proceedings for an offence under this Act, the Road Traffic Act 1960 
or the Road Traffic Regulation Act 1967) be relied upon by any party to the 
proceedings as tending to establish or to negative any liability which is in 
question in those proceedings"

Taken from the Road Traffic Act 1972, Section 37 - and the quoted in the 
Highway Code.

In other words - you 'cannot' prosecute a driver for non-compliance with a 
provision of the Highway Code 'alone. The Highway Code is just that - a code - 
not a law! Maybe this is semantics to you and me - but not as far as Police 
enforcement is concerned!

Hi all !

Rule 154 on ASLs of the Highway Code 1998 states that: 
Motorists MUST wait behind the first white line reached, and not encroach on
the marked area.

The use of the word "MUST" indicates that this is a legal requirement
(basically I guess that both stop lines have the same legal standing).

In York we have always put breaks in the stop lines if there is no lead-in
lane. 

Although in theory (and law) vehicles must stop at the second stopline if
they have passed the first many tend not to do so. I now set intergreens
according to this driver behaviour ie longest clearance and shortest
starting - just to be on the safe side.


(as for cyclists the cycling code rule book states that: "all highway
regulations are there for your inconvinience - ignore them" this comes just
before "the pavements are as much a part of the road as anywhere else - use
them when you feel like it")

Thank you, Andrew - very interesting.

In relation to red light cameras, as ASLs have no 'legal' basis (as far as I
understand)- as they are not covered under TSRGD or other legislation - is
it actually a traffic 'offence' for a vehicle to pass through a vehicle
stopline if it were to stop at the ASL (and not progress through the
junction)? I would have thought that the provisions in the current TSRGD
would be inadequate if the matter were to come to court. After all, the
Primary signal is normally alongside the end of the ASL (is it not?)

I have designed and installed many installations with ASL's and D' loops.  =
I have always located the loops at standard spacings from the vehicle =
stopline and not the advanced stop line.  My thinking behind this is that =
it is no different to any vehicle stop line.  All intergreens etc. are =
measured from the vehicle stop lines and vehicle extensions on the loops =
are not normally affected.

To reinforce this argument on one of our sites with ASL's and D' loops we =
have red light cameras installed.  The cameras loops are installed and =
configured around the vehicle stopline as this is the requirement set out =
by our local police authority..

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?
