Title: Filtering
Post by: dBfazer600 on 23 July 2013, 01:03:03 am
Do you and how long did it take you to filter with confidence and what are your do's & don'ts
 
I like to get up front and put the bike and myself in front of any other vehicle to show my intention as I have been in a position when cage drivers will try and race me with little success but try and force me over. They do not like a bike progressing.

Yeah  I filter. Took a few weeks from passing my test before I was confident, but it's actually pretty good fun and very useful during rush hour.

I do it slowly, with a great amount of caution and deliberately intense observation both forward and rear.

I try and stick to a "20 delta 15" rule I heard somewhere, which is maximum 20 miles an hour, and at most 15 miles an hour difference in speed to other traffic. That's fast enough for me.

There's a couple of junctions round my way that get proper jammed up every day at rush hour, I see others who presumably do them every day on way home from work filtering past stationery traffic at 50pmh upwards, a bit fast I think.

Important to watch the mirrors because when filtering you'll be changing position within the lane a lot, and you could easily fail to notice one of these guys had positioned themselves to the side of you.

Also watch out for gaps, as people will change lanes in to gaps without looking carefully for bikers filtering.

I tend not to filter past the police at the moment, I guess it should be fine but am never entirely sure.

Finally I try to filter considerately, I'm  happy to make progress when I can but try not to take the piss and so don't tend to position myself at the head of queues at junctions, but rather slip in somewhere a little back.

And I take care to thank them when they make room.

Andy

PS) Just to add that my main issue had been picking up punctures from the central reservation areas, the city centre roads round me are in a state, literally piles of screws and other metal junk.

I've only really started filtering on the fazer ( only had it a couple of weeks). Much as above, I don't rip the hole out it, and when passing stationary traffic only do 15-20 MPH. Ill maybe go up to 30-35 if its just passing stationary traffic in one lane though (I.e. overtaking).

Still get the odd cagers kidding on they can't see you then closing up gaps on you on purpose. Twats.

Anyone moving over to give me a bit of room gets a nod or a wave too, only fair :)

Andy only problems I have ever had is when I have not made it to the front as living in a city everyone is in a big rush. On the occasion I is talking about I was on a underpass and did not see a cyclist until I got round the apex. So I dropped back 3 car lengths to give the chap space and give other road users ability to see what was developing whilst the cyclist was at red lights. While stuck on the centre line on a duel carriageway cagers took it as a sign to push the limits and took it as a race although I only filter slowly and observe what is developing.
Reason I go up front is to show my expectation especially on multi lanes but this was on occasion I wished I had waited half mile back for all concerned. As a motorcycle I did think it better to hang back for the cyclist as this was on a quick round-a-bout onto the M1, A and B roads.
 
I is with you and mickvp on this one but with all the best intentions anticipating what was developing does not always seem to be obvious/predictable. For me as an old man slowly does it to expect the unexpected.

Another one to watch is when passing large vehicles in stationary traffic. I always come to almost a standstill as I get to the front of them, and peer around to make sure there's no pedestrians about to step out. Give the traffic as much room as you can. If there's anywhere a car could suddenly head for (side turnings, parking spaces, gaps,) well look for those kinds of possibilities and slow accordingly.

Travelling the M25 and you have to filter,did about 20 ,30 miles when leaving Brands races,get up to 70 ish inbetween cars as the speed of the cars goes from 30mph to 50 mph,up and down, when the cars get up to a reasonable speed slot into a lane.When they slow go back inbetween.Made easier by the fact that there are hundreds of bikes doing it so the car drivers are aware.

Post by: seangee on 23 July 2013, 09:42:17 am
Know exactly what is behind you and make sure all of it is accounted for. Mopeds in the city love to tuck in between your shoulder blades before doing a kamikaze style overtake on you. Also when you pass things you can't see past its best to assume something is about to shoot out of the gap.


Aside from that what the rest say. Personally I don't filter if I don't have to. Working in London means I do have to but if the traffic is going along at 25 in a 30 zone I just ride at 25.

I am as well, some peiple are really intent on getting to the front of the queue and trying to force cars to part. If there isnt enough space to filter then I sit, simple. It make maybe a minute of difference at the other end.

I filtered during my lessons, and once during my test. My instructor told me that if you don't filter, there's no advantage in riding a bike, so I was taught it pretty much straight away.

A few of the rules though:
Only filter through stationary or crawling traffic.
Headlight on and 1st gear only, to make as much noise as possible and attract attention.
No filtering over solid white lines.
No filtering over zig zag lines (i.e. approaching crossings etc.)
Don't go to the front of the queue, stay 1 car back at least.

Some of these are law and some good practice, but I can't remember which are which.

If the traffic is at (or near) the speed limit, I wont filter but if its going considerably slower I will. As with others, nomore than 10-15 mph faster than the cars I am passing and I do try to divide cars rather than pass them in an empty lane. The thinking here is that they know the other car is there and unlikely to change lane whereas if there is an empty lane next to them they could easily pull over.

It's in Roadcraft!
 
4 - FILTERING SKILLS. 
MotorCycle RoadCraft, page 126, 139 and 140.


Used when applicable, to make progress, usually between, stationary/slow moving lanes of vehicles.

 

Speed to be about no more than 10 mph higher than other vehicles though not at speeds above 30 mph. 



If traffic is held up by, say, temporary traffic lights and a large safety margin (space) is possible then, perhaps, by judicious use of the offside of the road, for example, then higher speeds may be both possible and desirable,

(space + view = speed). 

But this is really overtaking stationary traffic rather than filtering. 



When filtering past large vehicles extra caution is required due to the greatly restricted view.



Increased potential danger arises when vehicles are stationary or very slow moving – cycles, pedestrians, animals or vehicles crossing are a distinct possibility.




 When traffic is stopped, at traffic lights for example, look for traffic flow from the road crossing yours.

Side streets are deadly, keep a good eye out when filtering as you won't see the car cutting through the junction until you are on the bonnet

I always filter , but with caution . Use M3 a lot and can que from winchester down at times . So have to filter or whats the point . Eyes everywhere :eek  tho as some try to have you off by cutting gap as soon as they see you . Always keep a steady pace and keep on moving .

Filtering like a bastard every day up and down the A2 into central London in rush hour, good way to start the day
Title: Re: Filtering
Post by: Lawrence on 23 July 2013, 01:31:13 pm
Started doing it when I was on my 125, do it all the time if it avoids slowing down.  Can easily be 5+ miles if there's an accident or something up the A12 although doing it constantly gets tiring.  I tend to go through traffic that's doing up to about 60, much past that I don't bother.  Relative speed tends to be 10-20mph faster depending on conditions - fairly common up the A12 to get gaps big enough to drive a car through.

Said I don't if I don't have to. On an average day I do 36 miles of solid filtering each way.
Another tip - try to stay between the two outer lanes on a motorway and try to avoid left of the leftmost lane in town. People just don't expect bikes on their inside when they are in the left lane.
Title: Re: Filtering
Post by: Arfa on 23 July 2013, 02:30:27 pm
After riding into London everyday for last year, filtering is pretty much all I ever do. Whether it's 3 lanes of stationary traffic on A13 or weaving in and out around town fitting where ever I can. The fold back mirrors on the Fazer are great for squeezing through them really tight spots of grid lock.

Did knock out a couple of articles for my blog on filtering. One focused on slow moving motorways/dual carriageways and other for more round town type filtering. Have a gander, feedback much appreciated:-

I wouldn't recommend that, it's aggressive and can lead to problems (as you've noticed). I prefer to filter up to the gap behind the first car stopped at traffic lights etc and then wait for the lights to change. If they've seen you and wait, then go ahead and give them a nice "thank you" wave, otherwise look for an opportunity to pass them a bit later.

Remember that, if it's on zig-zag lines, it's illegal to overtake ie have your front wheel cross the line of their front wheels, so don't do that.

I regularly move to the first place at traffic lights. The logic is that motorcycle is a lot faster at start, so I won't slow people down - as if I wasn't there at all. If I stay behind the first car, I'm making a queue (AND skipping it :)   ).  So it is fairer to get there first, fly off (checking left and right for idiots going for "almost green still").

Of course, I do so when it is safe. Not always.



One question: how has this worked out for London so far?

"The advanced stop line (ASL) into the area designated for cyclists. London boroughs have recently started enforcing this!"


Is it a smart idea, or is it a pain in the neck. Asking because I would never stop in front of cars at a traffic light while on a bicycle. Would slow them down. Stay at the side, behind the first car, but never in front.  Does it make traffic move better, safer, or is it a bother?
Title: Re: Filtering
Post by: Hedgetrimmer on 23 July 2013, 05:58:45 pm
I'm a little more nervous about filtering since being taken out that way. It hasn't stopped me, but I'm real careful. If your job is riding in the city like yours, Stig, it's much more understandable as you'd never get the work done if you didn't. M25 is where I'm most nervous filtering! Still do it tho, just with care.

TBH, all I've heard and seen thus far is PCO's handing out leaflets informing offenders (bikers and car drivers) they will in the future be fined for crossing the ASL. I don't necessarily agree with it, and it does make things very awkward. As mentioned above, the best option is to probably not aim for the front of the queue, but for one car back. If you can't get in front of the lead car, safely and without going to far forward, it's going to lead to some sticky situations being sat beside a lead vehicle when the lights go green.

Personally, I think they should cut the ASL cycle box in half, cyclists left half, motorcycles right half. I am glad their fining cars/vans etc, these should definitely not cross the ASL.

As it happens, about 50% of cyclists I see ignore the cycle box anyway and either balance as far forward as possible waiting to dive between to the opposing traffic, with no regard to the red light.

If they're going to fine motorists/motorcyclists for breaking the rules, then they need a major clampdown on cyclists who do. I know it's a generalisation, but cyclists seem to think they can do any bloody thing. Course it's always somebody else's fault if they get knocked off :rolleyes

Fair enough. My post was based on IAM guidelines and avoids the idiots who think that Amber means "go" or problems such as you accidentally bogging down when you pull away and having someone run into you from behind.

I will, depending on circumstances "assertively position" myself in front of cars (eg if I'm turning right) or if there's traffic parked on the left just after the lights meaning that I'll have to try and merge into a moving stream of vehicles which are going faster because they've had time to accelerate from the lights.

I don't usually commute and I haven't been past my DAS that long, but anyway was filtering like a good un the other morning. I must have passed 2 miles worth of traffic in and around Leeds. I was being courteous, taking it easy and all that. Lots of cars / vans / trucks / buses moved over. (Thanks). Just the 2 jokers that spoilt it.

Anyhoo, I was mostly along the centre line between 2 lanes and noticed the back end was well lively over white lines, cats eyes, rubbish concrete joints, etc. heart in the mouth stuff when you've got vehicles either side.

When on a bicycle:

A yield sign = what it says.
A stop sign = a yield sign.
A green light = a yield sign.
A red light = a yield sign.

That's how I behave. Neve had any problems, except when considering green light as a go sign, instead of a yield sign. Some cagers don't like it, but I don't care, as long as I don't get fined. I DO make sure not to give any trouble to anyone - don't run in front of cars, do it only when it is free from crossing traffic. I even make sure not to scare the crossing traffic: if I can fly by before they arrive, I never do it because it will make them scared, perhaps brake or swerve. But when the traffic is clear... like I said: red light is a yield sign on a bicycle.

Makes sense. I move in front but stay to the side of the car when possible - so they can move past me in the same lane. Do it on the motorcycle, wouldn't do it otherwise on a bicycle. Just to be safe.

Slaninar, why would you not stop for a red light if riding on the road? A red light is an IMPERATIVE for ALL traffic. Also see far too many cyclists coming to a red light and just bombing over the pavement, scaring the life out of pedestrians. I know it's not ALL cyclists, but as with thoughtless motorcyclists, it gives the rest of you a bad name.

I don't sweat about that much. "Haters gonna hate" as they say. Stereotypes and so can't be avoided - some like (motor)cycles, some hate them.

I once stopped at a red light in a bus / cycle lane in London. I don't usually jump red lights on a bicycle but on this occasion there was no reason for me to stop - except for the bike cop stopped at the lights. He looked over, nodded at me and said "Don't be silly - get on your way"

When driving my truck if its safe to do so I drive down the centre line and keep as close to centre refuge areas as possible, the amount of debris that comes up is amazing. I do the same when it snows too, trying to keep the bits the bikes use clear of grit building up. You can do this in cars too.

In London you really don't want to do that, instead filter to the front and if you get there early in the traffic lights phase and there is room before the pedestrians bit, manouvre your bike on front of one of the cars at the head of the queue, this allows other bikers to filter to the front and get in 'pole position' as it were. I know this might sound aggressive and maybe it shouldn't be reccomended, but bikers in London do it anyway and cagers are resigned to it.
Title: Re: Filtering
Post by: Arfa on 24 July 2013, 12:22:44 pm
The only other issue with being aggressive and filtering right to the front, is if you are prompt in setting off as the light change, watch out for other cars jumping the red light and crossing in front of you! I've now got into the habit of doing a double take left/right, before flooring it. Loads of times I've done this but the scooter boy beside me has just hammered it and narrowly missed a red light jumper!

It may piss off those behind you, but it's better to hesitate on setting off, than have to put the anchors on half way across the junction and have the car behind up your ass

Being a derbyshire/yorkshire dales kinda rider  (country bumpkin) I don't have much cause to, but on trips into sheffield/york etc its pretty much a given or you sit there marinating in your kit. Practice practice practice, but never put yourself out of your comfort zone - and NEVER assume that they have seen you. Don't go any faster than you can stop in a hurry and be prepared for right turns/uturns out of nowhere.
 
I have to give massive props to the london riders out there that filter as they must have their testicles surgically enlarged to fight through that mobile carpark the M25 and the inner city traffic.

Always got to be careful when filtering up to junctions/roundabouts etc, as cars often change lanes at the last minute as you know!

I tend to slide back in line with traffic, 5-6 cars early when filtering down in that situation

Because whenver I or any other cyclist get into discussions of the subject with other on the internet or Councils or others start considering cycling safety etc it's the cyclists who ignore red lights that get brought up and the rest of us get tarred with the same brush.

And it's all very well saying "nothing was coming across" apart from the time when you didn't spot that someone *was* coming across...

60+ million people; 35million road vehicles- with the biggest percentage in Greater London/SE England. As a Londoner(by birth) & a Midlander by circumstance I am very glad I don't have to commute by any means of transport anymore. I am one lucky f****r who can ride for pleasure nowadays-mostly heading west of Brum for the joys of Welsh roads. As a retiree(& ex long distance cage,van & truck driver & two-wheel rider-including cycles & reluctant pedestrian!)) I can see the difficulties each group of road users has to face. Sadly its impossible to remove the selfish thoughtless incompetent & downright dangerous road "sharers"-but as motorcyclists we are at least aware of the dangers out there & guess we need to be entirely selfish regarding self-preservation. Theres no hard & fast rules that cover every scenario. Just have to apply commonsense! :eek

I don't have to filter very often, but have noticed that these days more and more cars do seem to move over, create more space for you and generally acknowledge the presence of motorbikes on the road. Dunno if it's because they spend more time in traffic jams these days or what, but it has made riding the bike much more pleasurable  :)
