Driving and Roads

"Supposed to know" may be the intention, but many don't (or have forgotten, or think they might get away with it... which they probably will with the current state of policing).
In theory you are supposed to know, otherwise you'd probably fail the driving test. I know there is a problem with too many signs in some places, but your original point is valid. :thumbsup:
Well, around Weston Village (Bath) they've been painting cycle logos on the road and dedicating half of it for those buggers where there's hardly room for cars to pass anyway. Since when did cyclists pay towards the provision and upkeep of roads (general taxation notwithstanding)?
A main road near me* had cycle tracks painted on both sides of the road - obviously narrowing the road. The opportunity was taken to reduce the speed limit as well (60mph/40mph down to 30mph). The interesting part is that there are some detector wires embedded in the cycle track and the pavement. And, yes, there are cyclists still cycling on the pavement.
Re prpr's rant on 20 mph speed limit signs, I've just spent a few days in Birkdale/Southport and the lampposts there are festooned with them. No one takes any notice, even the local buses travel at 30.
See my comment at #475. Same road as above (*) at end of cycle track. A non-enforceable advisory 20mph with speed trap flashing at legal 28mph drivers. :rolleyes:

Please will a Bristol native explain why the road signs at the roundabout where the Westerleigh road crosses the A4174 ring road direct traffic for Bristol and the M4, M5, and M32 towards Westerleigh? As far as I know that's just a winding country road that eventually comes out on the A46 close to M4 J18 having passed through Codrington (hardly a good route for HGVs, or even if you want the M4 eastbound - never mind anything westwards!). The obvious route is to continue along the A4174 to M32 J1, and connect with the M4 from there.

I can understand that might have been a diversion while the Bromley Heath viaduct was being rebuilt (between this roundabout and the next in the anticlockwise direction, ie heading for the M32), but that was finished months ago.

If the city council have had anything to do with it, I'm not surprised. Everything they do seems to make things worse. Been going downhill ever since the millennium, when they turned the Centre from gyratory to figure of 8, and made a lot worse by the previous mayor.
The green sign on the bottom picture has had something covered over - perhaps they forgot to remove it.

(I'm not a native, thank God - I just drive around in that area sometimes; thankfully a lot less than I used to.)

It does, I think the M4 (etc) markings have been painted over - but if you look to the right of that picture you can see where the traffic is signposted up the Westerleigh road off the roundabout.

(Gone midnight and some bugger is still letting off fireworks)

Okay... so I'm driving in the outskirts of Bristol (as I often do), after dark, approaching the A38 in Patchway from a slip road, and a triangle warning sign lights up in LEDs showing a bicycle. What the...? Then I spot a bicycle on the main carriageway crossing my path to join the road. Very good (especially as I came across a bicycle accident not long after it had happened earlier in the day).

The question in my mind is: how the hell did it do that? So there could be a sense coil in the cycle lane, but that wouldn't distinguish between a bicycle and a car that happened to stray into the cycle lane shirley?

Applying Occam's razor, are you sure it wasn't flashing a warning to any passing car to be aware of possible cyclists ahead (sounds like a black spot).

If it is intelligent I expect it uses infrared or microwave, or a combination of them, similar to some pedestrian crossings, to detect a cyclist.

Well, I go through that junction after dark every couple of weeks or so, so either the sign is a new installation or it is triggered by something other than me.

I suppose it might. There is a difference in the amount of metal in a car and in a bicycle so it's possible. On the other hand, it might just detect your vehicle and flash the warning assuming that a cyclist is there. Not that motorists take note of flashing signs. There is a low railway bridge near me. Height detectors have been placed some distance before the bridge (as viewed from either direction). Flashing signs warn over-height vehicles and a run-off lane allowing them to do a u-turn have been provided. And yet lorries and buses keep hitting the bridge.:rolleyes: Fortunately it is a test track so no scheduled rail services are delayed.

Many things have hit that bridge over the decades (it's not even that low - about 14'6" I think). I think the most notable was when a flat-bed lorry carrying a JCB (or similar) hit the bridge. The JCB's arm swung round and hit a bus going the other way. ISTR a couple of kids on board were killed.
I always think of it as the "Bill your dinner's ready" bridge, as that was the graffiti on it which lasted probably 20+ years before it was painted over.
Fortunately it is a test track so no scheduled rail services are delayed.
The stupid thing is that the trains stop about 1.5 miles back down the line. There has been a huge amount of activity (relatively speaking) on that track in the last 18 months. I haven't seen anything go further for a very long time (Network Rail insisted on the nearby very expensive bridge being built over the then new A52 missing link and it's hardly ever been used).

That reminds me... I once drove an 11'3" van under a 10'9" bridge. That was on the main line between PAD and BPW. But I did know what I was doing and trebled checked at varying distances away and at dead slow speed. The highest part of the vehicle actually fitted comfortably under the highest part of the bridge.
Some of my colleagues have had er, incidents, shall we say. Two this year. But not really their fault - a fail-unsafe system; and it had recently been changed without anybody having been told. Classic.

I've never seen anything go over that A52 bridge. Anyway the buffer material near the Melton Road, close to the old Edwalton station looks completely knackered. Probably the A52 bridge needed to be there in case the train didn't stop in time. Don't want a train landing on the ring-road.
