Traffic monitoring loops on cycle paths

Discussion in 'Commuting' started by goosander, 5 Oct 2007.

    About a week ago, I saw a traffic monitoring loop (the type of thing usually used to control traffic lights or count vehicles) being embedded in to the tarmac on a cycle path at Dalmeny and have since noticed that there is also one near the Forth Road Bridge as well.

    Does anyone know the reason for these being installed? I presume that they could be used for counting the number of cycles using a route but it seems like a lot of money to spend just for that, so I'm wondering if there is a more sinister reason behind them such as monitoring of cyclists by the authorities or if it hints to future cycle path charging by Edinburgh Council (wouldn't put anything past those cretins).

    They are just for counting bikes to assess cycle track usage. They have them down here as well. The installation is just the wire loop and a box to hold a recording unit. The recorder itself will only be present for a couple of months a year at most.

    The counters are there just to record cycle use for reporting purposes. Loops are usually permanent counters and in use continuously (there's probably a small grey cabinet in the vicinity housing the counter). There's nothing sinister about them!
  4. They have other loops/ counters in Fife, for instance on the West Fife (Dunf to Clack) cycle path. Nothing sinister about them they'll just be used to count numbers and hopefully justify the provision or lead to further improvement.

    If I saw one of those I'd ride over it back and forth repeatedly for ages to confuse it.

    Cycle charging! I'm still laughing!

    More than likely to assist the LA to dispose of funds so they can claim the same amount next year, as if they have a surplus next years funding will be cut by that amount.

    Not really. Local Transport Plan funding is awarded by the DfT based on a formula then plus or minus a percentage depending on the LA's quality of LTP and performance against targets. LA's don't "claim" the majority of their transport funding. The only things an LA can bid for is bridge strengthening funds (linked to mandatory requirement to accommodate 44 tonne HCVs) and major scheme funding - a local transport scheme costing £5m or more. The LTP is not a bid document.

    Damn, that ruins a perfectly good conspiracy theory :biggrin: (still a waste of money though).

    More seriously though, do these things actually work reliably on modern bikes given the low iron/steel content in modern bikes. How do they distinguish between a bike and other metallic objects e.g. a baby buggy.

    You mean targets like the number of mile of cycles paths created, regardless of whether they are any use or not or the number of silly traffic 'calming' measures installed regardless of how unsafe they are?

    Performance indicators now generally have to be "outcome" rather than "output" based - "miles of cycle lane" would be an output (but doesn't necessarily lead to an outcome), whereas "increase cycling trips to the town centre by x%" would be an outcome.

    Seems that Fife's targets are:

    * Increase cycling to key Public Transport Interchanges by 10% by 2011
    * Increase cycle usage on key monitored routes:
    - Across the Forth by 10% by 2011
    - Across the Tay by 8% by 2011
    - In St Andrews by 6% by 2011
    - In Dunfermline, Glenrothes, Kirkcaldy by 4% by 2011


    It also explains the presence of the counters.

    We've got several cycle paths with induction loopps around Fareham and Gosport.

    They're all linked to the traffic lights and it's a satisfying feeling when you can cycle over the loops to activate the lghts and then go straight on instead of crossing the road. :biggrin:

    Why should common sense and the truth ruin a good conspiracy theory.

    The Daily Sexpress has made a fortune out of the Diana Conspiracy without letting these small problems get in their way!

    The working depends on pressure. I believe that in theory they are calibrated so the pressure of a buggy would be insufficient to trigger.

    I remember as a kid (in the old days when these things were rubber tubes and mechanical counters) trying to set them off by jumping on them or iding a bike over them - it took some pressure to do so!

    Depends on the counter type how they work...


    Tubes are still widely used for automatic traffic counts.
