Riding to work this morning up Burlington Street Walkerville (Levels Bikeway) and noticed some new paint on the roadway with some very small bike symbols painted on the road. Photos attache- can someone correct me if I'm wrong, but I don't believe this meets any Australian road standards. There's also no additional signage (maybe they are planning to add in the future?).

Experience tells me this is just going to lead to more conflict and potential injuries- inexperienced riders run the risk of getting doored, people riding outside this zone will be open to abuse and punishment passes by drivers who believe these are bike lanes (this is a very regular occurrence I find when I'm riding Galway ave).

Very strange.

As it stands, it's not a bicycle lane because cars are not allowed in bicycle lanes.

If they intend to add another white line to the left of the bicycle symbol, to make a bike lane in the door zone, then that would be very dangerous; because there isn't room for a bicycle lane and a decent car park width without shoving the bicycles right up against the car doors.

Judging by Google Maps, it's not a very busy road, so it would be a good candidate for sharrows. (Which basically mean, this road is quiet enough and wide enough for cars and bicycles to happily coexist, and this is part of a bikeway). So why they've gone for a bicycle lane type symbol is a mystery.

Perhaps contact the council and ask.

http://www.walkerville.sa.gov.au/webdata/resources/files/00%20TOW%2... Council's draft plan (late 2017) says:

"Provide clearly marked, attractive bicycle lanes and way-finding/ navigation signage: Smith Street • Church Terrace • Vale Street and Harris Road • Stephen Terrace • Burlington Street • Lansdowne Terrace"

Thanks for the feedback gents. I've drafted an email, I'll send it from my personal account when I get home tonight

Kristian,

These look like what used to be called 'Guidance' or 'Advisory' Lanes. These were intended to signal provision of 'shared space' outside motor traffic lanes that could be used for car parking, bicycle use and use by mobility devices etc.

They required a specific road width which - if I recall correctly - was somewhat less than the width required for use of actual bike lanes, particularly given more recent recommendations that bike lanes be accompanied by a 'buffer' lane to guard against 'dooming' incidents and reduce car/bike collisions.

A good example of use of Advisory lanes is on Swan Trc, Semaphore where they have (IMHO) been quite effective in moderating traffic speeds and providing some 'separation'. 

My advice (from local Council engineers) is that use of 'advisory lanes' is no longer supported by the current Aust Guidelines. Where they are currently installed they can (apparently) stay, but no new ones can be installed. I actually really like them where they are appropriate - relatively low traffic densities and likelihood of 'mixed traffic' on then road. However they are definitely not a substitute for legally defined bike lanes!

If you're correct, then those lanes "Advisory" lane markings are a terrible idea, because they fooled everyone else on this thread (or at the very least, me) into thinking they were meant to mark a proper bicycle lane.

Peter,

Your reasoning is IMHO pretty good and probably why these are no longer 'allowed' by the guidelines! If Walkerville Councils following the out of date guidelines someone in authority needs to take them to task...

Personally I don't think even bike lanes should be marked without 'buffering' lanes between them and parked cars (see attached).

Buffer spaces have been used very effectively on Semaphore Road and there's also an excellent example of their alternative use between the bike lane and the car lane on the Southern side of the Jervois (or 'Hart St') Bridge at Semaphore. At this point on the bridge the road is descending with a mild right-hand curve and late afternoon drivers are often looking straight into the sun! (see attached)

Melbourne VIC were installing buffer zones between bike lanes and travel lanes, by 2009 or earlier. I presented examples at two Prospect Council meetings, while council considered 'upgrading' Churchill Rd. Council -- in its wisdom? -- declined to include buffer strips on this freight route. Thus cyclists too close to trucks, according to Austroads and more recent road rules of "give cyclists a metre".

Examples provided at this AC discussion.

I had a look at Swan Terrace Semaphore and it does indeed have similar markings:

I assume the reasoning in both cases is that it's not quite wide enough for 2 marked driving lanes, or for normal lane + bike lane + parking.

You say it works quite well. But there is a problem (or at least a potential problem), that it looks very much like a bicycle lane marking. In my opinion, the "correct" thing to do here (and on Burlington Street Walkerville) is to just remove all lane markings (except the line in the middle of the road); then it's one lane in each direction, but it's a lane wide enough to accomodate both parking and cycling on the left. Sharrows could then be added towards the left, to indicate a bicycle route without the misleading impression of a bicycle lane.

I think that if PA/E Council were to redo this they might indeed use shadows. Remember that these 'advisory' lanes are no longer permitted. They do have a strength in that everyone, including half-aware drivers recognises what a solid line means - 'don't cross'! So the lines do indeed informally mark out separated spaces. However they might indeed be confusing for cyclists and they don't solve the problem of inadequate road space for separated provision  (also known as the 'dooming' problem).

...that should have read 'dooring problem' of course!

That is a dooring zone - I would certainly ride outside it whenever a line of parked cars presented.

Frankly many motorists  can not park close to the kerb increasing the need to ride further to the right.

If that truly is a council/government paint job then someone should be in trouble, there is absolutely no space next to those parked cars to pass safely.

Definitely the ‘cycling area’ is marked unsafely within the dooring zone.

From the photo, I wonder if the space between the parked vehicle and white lane even allows for ‘cyclist envelope’.
