Sustrans announce funding injection to improve and "reduce conflict" on most heavily-used section of the Bristol and Path Railway path

Can they not build an elevated fly-over sort-of-thing? Would also keep rain off the pedestrians below.

Something like this, running above the whole 1.7miles

Bet they'd raise some pettifogging objection about 'budgets' or something, though. In which case, maybe this would be the low-budget version

Get off the roads there's a cycle path...

Get off the path were are using it as a dog toilet and meandering area!

Let's all remember that these are all nice problems to have!  If there was a similar route between every decent sized town in the country, how great would it be?

When cars became common on roads, it was necessary to start painting lines down the middle, and to start training their operators.  I'm not suggesting a licence to use the path, but a few signs along it at joining points and before pinch points reinforcing some key messages e.g. "the path is for everyone", "please keep your dog on a short lead", "pass young people safely" etc might just dial down the conflict a little.

Keep left makes sense and most cyclists do. I think it makes sense for runners to keep left too, as it's easy enough to adjust to running speed on a bike and soft pedal behind a runner going in your direction till it's clear to overtake. But for walkers, I'm not at all sure; probably easier for riders and runners to approach them head on and overtake, and for the walkers themselves it's more sociable to walk side by side. 

A lot depends on time of day; what's fine on a Sunday afternoon (for instance strolling along side by side) is not good at 8a.m. on a weekday. 

I  helped to build this path as a volunteer and have used it a lot since it opened in 1979. The main problem, as mentioned in other comments, has always been groups of both cyclists and pedestrians taking up the entire width of the path, or wandering about without looking around. There are no signs to inform or remind people not to do this. Maybe a sign every quarter mile or so saying 'keep left' and/or even 'ride single file' would be useful. And maybe a central dividing line? Widening the path where possible would obviously help: there are quite a few sections where unused space is available to the side of the path.

I'm guilty of riding too fast along the B2B path, know my best time was less than an hour from Bath to Lawrence hill on my old MTB but that was the old path route, not the current one which was diverted for the ring road. Nowadays the path is a nice 50 minute ride with due care taken around peds, kids and dogs. On the way back into Bristol I'll reduce the effort before Clay Bottom bends and even more once over the B4469 bridge and effectively freewheel to Devon Road.

I commute from Bath to the centre of Bristol along the railway path most days. I go reasonably quickly for most of the route, but it's a shared use path. If pedestrians are there then they have priority - i make sure I give them lots of space and slow down. A little bit of consideration (i.e. not being a total cockwomble) costs me nothing - even on a really busy day it still never takes me more than an hour door to door for my commute. Slowing down around pedestrians, being respectful, and giving space (to both walkers and other riders) really isn't complicated. 

Widening the path, especially at the narrower windier Bristol end, should hopefully make it an even nicer experience

I use the B&B path and, when you've been 'barrelling along full tilt' for over half an hour it's a bit annoying having to reduce speed to a 'pootle' because of path congestion; but that's exactly what we should do.  Kind of nice really; a bike path needs widening because of volume of cycle traffic.  Maybe we're heading in the right direction after all?

They really need to widen and resurface the section from The Locksbrook Inn through to Green Park. It's narrow, always covered in mud and there are tree roots breaking through.

Some riders tank through the pinch points with no regard for pedestrians or other riders. From my experience, I'd say that it doesn't matter what bike/kit they're on. Idiots are simply idiots.

Some sections could do with widening but more at particular pinch points, eg the bridge St Philips Causeway. Introducing segregated sides for cyclists and pedestrians will not work. It does not work anywhere! Pedestrians do not stick to their side; not surprising when their area is artificially narrowed (got to allow for kerb or at least a white line, so overall width is less than all-use) and the cycle side is usually smoother... It will be a disaster, with cyclists crammed into too narrow a space. See the Concorde Way near MoD for an example. 

I use it little - generalised hand-waving irritating issues I found when I have are

* aimless wanderers - seemingly malice free but situationally unaware pedestrians generally milling across the width of the path. Generally surprised.

* I Am A Dog Walker - and you better not come anywhere near me or my hound - mainly through the residential Bristol end. Sometimes on the aggresive end of passive-aggressive.

* small groups of twats at speed, on decent bikes, decent kit, look the business, a few abrest who seem to take the attitude that they own the path and you better get out of the way mister because i'm not even condescending to look at you. Idiots. One of my brothers uses it much more than me, and I think it's this that seems to get him more riled than the other stuff as well. 

Apart from that it's not too bad - bit more room would seem like a good idea though.

I don't often use that section of the path, but I do know that it's far too narrow for the amount of traffic and has a few blind-ish corners. There's definitely a few cyclists who feel agrieved when the walkers go over onto the cycling side (I certainly used to be guilty of that) and don't even get started on the dog walkers that take up both sides.
