M25 widening proposal
 

I've just found http://www.highways.gov.uk/news/pressrelease.aspx?press
releaseid=425156

Construction of an M25 managed motorway scheme for junctions 5
(Sevenoaks) and 7 (M23) is proposed to start in 2013/14.

The press release says it will be the "first M25 'managed motorway'".
I don't know why the scheme between M3 & M4 does not qualify already.

"The hard shoulder will be converted to a traffic lane to add extra
capacity. Variable mandatory speed limits, displayed on overhead and
verge-mounted signs will help smooth the flow of traffic and reduce
congestion on this busy section of motorway."

The M25 often seizes in the AM peak between J5 & Clacket Lane Services.

The term "managed motorway" means that the hard shoulder is available as
a traffic lane. The variable limit schemes on the M25 don't currently
include that.

capacity. Variable mandatory speed limits, displayed on overhead and
verge-mounted signs will help smooth the flow of traffic and reduce
congestion on this busy section of motorway."

Presumably the part-time use of the hard shoulder is what makes it a
managed motorway?

It doesn't apply to the section from J10(A3) to J16(M4) because that
just has variable speed restrictions on the existing carriageway 3 or 4
lanes as appropriate. What they are talking baout here is using the hard
shoulder as an extra lane under certain conditions. They will need to
build extra refuges so that vehicles can pull right off th e road if
needed, put up lots of variable signs, and probaly lots more CCTV. I
just wish they'd do something between J10 and J12 which always grinds to
a halt for no real apparent reason.

Aren't all existing motorway limits 'mandatory'? They are not, in
general, enforced particularly well.

There is already a section around Brum that does that. Part of the M42
IIRC, I drove on it last week,

The limits with the number inside a red circle are mandatory. If the
number is shown accompanied by amber flashing lights and no circle, it's
an advisory limit.

That was the original pilot scheme from 2006, which was deemed to be
very successful, so the idea is being rolled out more widely. It's
already operational on the M6, with the M1 under construction and many
more to come.

The limits with the number inside a red circle are mandatory.

And enforced by speed cameras linked to the changing limit on every
second or third gantry (less often on the M42 stretch I think but it
has quite closely spaced signs). Once you know what to look for, you
can see the camera fitted ones as you approach them.

It's often said that the ones on rectangular signs in the central
reservation are merely advisory.
