Is there any poster in this group that works in the field of two tube
pneumatic testing of traffic stats and how does the data affect traffic
rules and speed restrictions.
This form of testing can give number of, type of vehicle, speed of each
vehicle type.
I started a riot in an Australian news group by suggesting that if the
testing showed that everybody traveled less than the limit they may
reduce the limit, the consensus of opinion was that I was a stupid old
goat and it would not happen and all the other factors measured would be
the cause of the reduction.
Be that as it may, does anybody have inside info as to the uses of this
testing in councils or road authorities and whether the measured speed
was a big or small portion of the consideration.
I am asking in your group as it is a much bigger cross section, the

You'd like more abuse than from 15?

Taking a time averaged survey before spending money on an issue is
usually the norm. Often safety related, not a ticket cash raiser. If no
real issue found, no need for restrictions.

There are other reasons for reduction of speed limits in heavy slow
traffic (i.e. M25) but these are thankfully temporary.

But these poms are irrelevant to what happens in NSW with the
reduction in speed limit on a road like that. The only reason for
the use of the two tube meter system in that situation is because
the RMS requires traffic volume data before making any change
to the speed limit on a road like that, other than the general
change to speed limits like the change of many with 50 to 60
when there are few residential houses along the road, recently.

There are **** all roads as narrow as that with almost entirely continuous
double white lines down the middle of the road that have a 100 limit now.
Thats why the speed limit was dropped to 80. not because they measured
the speed most people drive at below 80 as you claimed.

If they are anything like the pneumatic sensors used in the UK I would

They do in fact get used for measuring speed and
the 1 foot roughly spacing is fine for doing that now.

I find them annoying for two reasons:

1) they seem to have no logic to them. The other morning I got on the
M60 clockwise at junction 10 and found a 50 sign illuminated at the
bottom of the sliproad; gantry signs showing 40 at the top of the
sliproad (beginning of Barton Bridge); gantry signs at the other end of
the bridge showing national speed limit; and gantry signs at the
following junction showing 40 again. 40/50/70/40 in a total distance of
just over a mile! Surely they should be showing 40 from the start of the
sliproad to that 3rd gantry. On top of that they were showing 40 on all
three lanes of the M60 and on both lanes of the slip-road to the M62,
plus an accident sign on that 3rd gantry ... with no indication of
whether the accident was on the M60 or M62. The wrong decision of which
way to go at this point can mean being stuck for an extra hour - from
bitter experience!

2) It is very easy to keep up with the flow of the traffic and within
the limit, but then have a lapse of confidence and a sudden panic, in
case the gantry you have just passed had a lower speed displayed.

But not installed with any precision to give an accurate speed indication.

My annoyance is that often these monitoring devices are placed on the

I'm sure that the manned traffic surveys are only performed by teachers
who are making extra money when the kids are off school and when traffic

Around my way these surveys have resulted in at least 2 off

Just like when assessing the suitability of road to sustain e.g an
additional 50 houses, they take all the photos during the day when most
people are at work, rather than at night when dozens of extra cars are
double-parked or half on the path.

We've had the opposite.

A simple traffic-light controlled cross-roads where one leg had almost
no traffic, as it lead to a dead end. From the road facing the dead end,
it was clear that widening the road by 2 to 3 feet would allow
left-turning traffic to pass the waiting right-turning queue. Instead
they spent £1.5M completely redesigning the junction so it no longer
aligns, traffic turning right must bear left, turn right at lights to
the left of the road opposite and then wait at a second set of lights at
the road opposite. The queue waiting to turn right still extends far
enough to block left-turning traffic from reaching the left-turn filter!

Yup.

Once upon a time a junction at the edgfe of a local town had no traiffic
lights. To turn right one simply waited unril one could or there was a
gap in te tyraqffic.

There were alomsot no delays.
Now it has traffic lights there are always queues.

Same for pedestrian crossings. Before there were Zebras, and peope just
crossed when they could and traffic stopped when it saw them. Now there
are lights with hoplessly long delays and on periods which ****es off
pedesatrians and motorists equally.


Its all been designed by a moron,.

Its all been designed by a moron,.

The common design solution around my way is not to synchronise the
pedestrian crossing lights with the traffic lights at busy junctions.

After waiting many minutes in a car for the traffic lights to go green
you are stopped in your tracks if you are third in the queue by the
pedestrian crossing light often going red. By the time the pedestrian
crossing light has turned green again the traffic light is now red! You
now have to wait again in a car for many minutes during all of which
time the pedestrian crossing could be made available to pedestrians.

I greatly dislike crossing lights very close to roundabouts. It
is easy to think that the actual roundabout is light controlled
when it is not. Conversely, leaving a light-controlled roundabout
it is possible to read the crossing lights as repeaters for the
junction you have just been through.

Whilst on the subject of crossings, am I alone in hating the
design with the pedestrian lights pointing up and down the road?
I understand the reasoning is that you will see the light if you
stand at the crossing and look towards oncoming traffic, whereas
most folk, in my experience, look across the crossing, in the
direction they want to walk, can't see the light, and there
doesn't seem to be an audible warning.

If standing next to the pole, I occasionally make use of the
tactile indicator, fitted for those with vision problems, but how
many people know about them?

They are not always perfect but they do seem to damp down the
oscillations. M25 ones are pretty good. The M6/M5 ones southbound were
doing a reasonable job on Saturday

You are wrong, do some research,they can tell speed and the type of
vehicle and the speed of differing vehicles

FMurtz wrote:

I think it's closer to say they can imply the different types based on
axle counts etc, but there will be errors when vehicles pass the strips
on opposite carriageways at the same time.

Though even some firms who do video tracked vehicle surveys seem to
concede that the errors in identifying vehicle type with pneumatic tubes
do roughly cancel out in the long term.
