The wording in TSRGD 2016, however is "Cycle lane, track or route". If
it is on the carriageway and is not part of a lane, the assumption would
be that it indicates a route.

Luckily there is further guidance on the use of 1057, which is a bit
more detailed than TSRGD's description.

LTN 1/20 10.5.4 includes "Providing road markings to highlight the
presence of cyclists to other road users, such as cycle symbols to TSRGD
diagram 1057, lines to TSRGD diagram 1010 and advisory cycle lanes, as
well as coloured surfacing". 10.7.35 allows this on the approach to a
mini-roundabout: "Cycle symbols to TSRGD diagram 1057 may be placed in
the primary position to guide cyclists and to alert motorist to their
presence."

Chapter 6 of London Cycling Design Standards 6.2.5 includes this:
"Diagram 1057 cycle symbol markings should be selected according to the
width available: usually medium-sized, but small for cycle tracks and
large for ASL boxes. They are used, orientated in the direction of
travel for cyclists, in three distinct and well recognised ways:

• For conspicuity: alerting other road users to expect the presence of
cyclists
• For positioning: suggesting a recommended line of travel for cyclists
• For wayfinding: indicating a route, particularly at a decision point
Any use of this marking should either meet all three functions, or
positioning and conspicuity without an explicit wayfinding function.

The cycle symbol should never be used for
wayfinding where it compromises the positioning
function, particularly at junctions and past parking
and loading bays."

You are correct in stating that 1057 outside a lane on a carriageway
does not necessarily indicate a route as I had previously thought.

However, if a cycle route in London has 1057 at 150-200m intervals (on
local streets), or 20-30m intervals on a main road route (LCDS fig.
6.2), it's an "otherwise signed" route. It's not a particularly well
signed route and not using 1057.1 for the route number is unhelpful, but
as some CS and Q route numbers appear to be changing to C route numbers
they could be out of date anyway (unless Will Norman changes his mind,
or Shaun Bailey has them all ripped up).
