Traffic Lights...

  1. There is a new set of traffic lights near my place that has two
    different lights for the pedestrian crossings, the usual one with the
    little man, and another one attached on the side with the symbol of a
    They both go red/green together (that I have noticed anyway) and there
    is of course only one pedestrian button.
    I find it most puzzling, and can't figure out why the extra bike light
    is needed, anyone got any idea?

    ** It is normally illegal to ride a bike across a pedestrian crossing.

    See rule 248:

    Must be something special about your new crossing - like it is part of a
    designated bike path.

    A bike probably is considered to be a vehicle (it is for purpose of
    drink-driving laws in QLD) and therefore probably not allowed on a
    pedestrian crossing.

    With all the traffic congestion problems, environmental issues of
    vehicle use, and the "obesity epidemic", governments seem to be
    bending over backwards to do anything they can to encourage use of
    bicycles and walking, providing extensive walkways, bike paths etc,
    this is probably another way to encourage bicycle usage.

    Crossing might also be near or part of a bike path and this makes life
    easier for riders.
  4. Yes, there appears to be a designated bike path in at least one road
    approaching the intersection.
    But the thing I don't get is that the bike light does not appear to
    work independendly from the pedestrial crossing light, so presumably
    the bike rider would still have to press the pedestrian button to
    I have not seen any seperate light cycle specifically for the bike.

    Perhaps it is just to indicate "the designated bike path crosses the
    road here"?

    ** ROTFL !!

    Course he has to when the light is red, if he does not want to get mown
    down by a bus - dickhead !!

    ** Jones is a real hoot - ought to do stand up on TV !!

    Almost compete with " Steady Eddy " maybe.

    ** It allows the bike rider to RIDE across the crossing without breaking
    the law.

    Imbecile !!!

  6. Fair enough.

    Phil, any truth to the wide spread rumour you will be setting up a
    stall at this years Wyong field day to peddle toasters and offer a
    free signed T-Shirt to all attendees?:

    I also heard you will be giving a half day lecture on inspection,
    testing and reporting of faulty IEC mains leads? I'm afraid I won't be
    able to make it, but will course notes be available?

    Dave :)

    ** I take my comment it back, Jones is no competition for Steady Eddy.

    Steady Eddy's routines are actually funny.

    If you really want to know all the boring details about Bicycle
    Crossing Lights, download this PDF file from the RTA NSW website:
    and read Rules 260, 261 & 262 starting on page 8.
    Very soporific stuff.

  10. They left out the part about having to push the pedestrian button.
    Must be lots of confused bike riders still sitting at the lights
    waiting for them to turn Green! :->

    Dave :)
  11. I know of intersection like this on my way home. It has an inductive
    sensor in the bike lane. When the bike light is lit, the traffic has a
    red turning arrow.

    It's probably just wired in parallel to the pedestrian walk light. I
    don't see why they would have a separate crossing cycle (pun not
    intended) for bikes and pedestrians, and I doubt the pedestrians would
    respect it if they did.

    It's likely to be just a dead-simple "idiot-proof way" of telling
    cyclists - regadless of how low their IQ is. - that its ok to ride a
    bike across THAT crossing, by having a pretty outline of a bike that
    turns green or red. .

    (lets face it, there is NO shortage of lame-brains in this country
  13. Ah-ha, so some of them actually do something useful!

    All bike riders are confused or they would not want to ride on
    They even ride on the M7 (Western Sydney) when there is a separate and
    safer dedicated track for them built safely away from the motorway at
    immense cost.
  15. I've seen that on the M7, future Darwin Award winners for sure.

    Usually the idea is that the bike indicator goes on and off without
    the need for a press of the button - just so the rider doesn't have to
    dismount.. It usually mirrors the pedestrian light, but should be
    functioning with or without Joe Bloggs pushing the crossing button.

    It could also be wired incorrectly :).

    Does it go up and down every hill while the motorway is cut through

  18. John G

    John G Guest

    Yes it goes up and down some small rises in western Sydney which is
    generally flatish.
    We are not talking about the Blue Mountains here
    Anyway I thought one of the advantages of cycling was the exercise.
  19. Most people don't like to do it tough, if there is an easier option
    they will take it.
    Same at the gym.

    All bike+pedestrian crossings I can recall have the pedestrian
    flashing red whilst the bike stays green. It only changes to red when
    the main lights go to amber.
