    Primary schools teach the Be Safe programme for walking, cycling and PT, but kids cycling to school are among the most vulnerable road users, that’s why many are seen cycling on footpaths, it’s safer than the road for them. One of the best things in recent years has been more cycle lanes, but they are not available everywhere. A road training programme for cyclists would be helpful imo.

    Why don't you put the extra reflector strips on the car body? Why don't you practice what you preach?

    The level of intelligence needed to satisfactorily complete one is equivalent to what 99.9% of the population achieve through observation. Considering the behaviour of many licensed road users, the truth is that such things are not the panacea people think they are. What is needed is enforcement, nothing more, nothing less.

    You haven't travelled this country much if you think everyone has access to a footpath.

    Would this training program be mandatory ?



  • Registered Users, Registered Users 2 Posts: 31,622 ✭✭✭✭AndrewJRenko


    A training programme like this perhaps? It's being replicated all over the country.

    It's great to focus the training on kids, as it avoids having to do anything effective with the group of users involved in 99% of road deaths and injuries.

    not already in thread. Cavan Council chamber, January

    “People should be made to wear hi-viz vests and if they don’t wear them, then they should be arrested and charged,” he fumed

    'many are seen cycling on the footpath' is not the same as 'everyone has access to a footpath'.

    If they're going to make hi Viz jackets mandatory, can they introduce hi-viz bricks and holders on bad bends ,and dangerous crossing,- apparently effective in Canada..

    No but when a poster calls for road tests and then tries to fob off the idea of kids cycling on roads with nonsense about footpaths then it's worth pointing out.

    Ah lighten up, I’m not telling anyone what to do, unlike others. This is just a discussion is it not? Everyone entitled to an opinion?

    You've loads of opinions about cyclists and pedestrians though, and very few opinions about what drivers should do. Isn't that a bit twisted?

    back on track please with the hi-vis discussion, further OT posts will be deleted without comment



  • Registered Users, Registered Users 2 Posts: 5,487 ✭✭✭standardg60


    We've had two recent court cases regarding pedestrian fatalities due to drivers not seeing red lights at crossings. Clearly all traffic lights should now be encased in hi-vis.

    Levity aside your car has these things called lights, which allow you to see things which may not be lit up, so far they've worked for me as I haven't hit anything. Of course I was looking where I was going too which helps.



  • Registered Users, Registered Users 2 Posts: 9,570 ✭✭✭TheChizler


    There was one of these at a junction I regularly cycle past, drivers kept driving over it until they stopped replacing it. Can't account for people not looking.

    You'd imagine someone in the motor industry safety business miight have noticed that? But they don't really give a shite about anyone outside the car…..

    I have one of those cycling jackets with large panels of reflective fabric. I often notice when I'm leaving the office, the sensor at the exit - which normally you have to wave your hand right beside - will detect me from several metres away and open up.

    I have no idea how it works, but obviously the hi-viz is confusing whatever sensor system is there. I presume a similar effect is at play here.

    I also didn't think anybody trusted pedestrian detection systems. The list of conditions that might cause a false negative or positive for Toyotas (for example), is huge - some select examples below from https://www.toyota.com/content/dam/toyota/brochures/pdf/tcom/CFA_TSS_precautions.pdf

    PCS may not recognize a vehicle, pedestrian³, or other detectable object in the following conditionsand environments:

    When a pedestrian, vehicle, or other detectable object suddenly appears in front of the vehicle
    When driving on an up or down slope
    Motorcycles may not be detected
    When a vehicle or a pedestrian approaches your vehicle head-on or nearly head-on
    If the sun or other light is shining directly on a detectableobject ahead
    Bicyclist may not be detected
    When pedestrians are walking in a group or are close together
    When a pedestrian or bicyclist is staying close to or walking alongside a wall, fence, guardrail, vehicle or other obstacle
    If a pedestrian or bicyclist is moving fast
    When a pedestrian or bicyclist carries large baggage, holds anumbrella, etc., hiding part of the body
    When a pedestrian pushes a stroller, wheelchair, wheelbarrowor other vehicle
    If a bicyclist is riding a child-sized bicycle, is carrying a large load, ifit is being ridden by more than one person, or is riding a uniquelyshaped bicycle (bicycle with a child seat, tandem bicycle, etc.)
    When a pedestrian or riding height of a bicyclist is 3 feet orshorter or 6.5 feet or taller
    When a pedestrian or bicyclist is on top of metal on theroad surface

    So I guess just add 'when a pedestrian or bicyclist is wearing reflective clothing' to that list. They already have:

    When a bright light, such as the sun, is reflecting off of a detectable object, or the detectable object is white and looks extremely bright

    It might be easier to list what they can actually detect?



  • Registered Users, Registered Users 2 Posts: 8,161 ✭✭✭buffalo


    That would mean guaranteeing a detection - these systems are all unreliable when in the wild.

    My collision detection warns me when there's a pedestrian straight ahead in my line of sight, even though the road is bending away from them and the car is following the lane. They are all assistance systems but the driver must always remain attentive and ready to take action/control.

    I don't know if this helps or hinders the discussion, but the new Dublin Bus electric vehicles have cameras for "rearview mirrors" , in the early (dark) mornings and nighttime, they are feckin useless, but there is an infra red button I can press to assist with the dark.

    Anyone behind me wearing their hi viz in the yard is instantly visible - well their reflective stripes light up like mad, and when I'm out on the road, roadsigns in my mirror are stand out.

    I always presumed it was the visible lights on reflective things that made them "shine", but apparently not.

    I presume the above technology could be confused by different lights, or how the sensor perceives them.



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 52,202 CMod ✭✭✭✭magicbastarder


    sounds like that system is an active one - it sounds like it has lights that emit on a particular wavelength and cameras which look for that specific wavelength so it knows what it's looking at. but the one buffalo is describing is passive, where it's just trying to guess based on what the world around it is feeding to it.

    IR reflects off a mirror similarly to visible light afaik, so sounds as if reflectors generally return IR light effectively. So reflectors on a bike should work too. Or a Sam Browne, which is only reflective and not fluorescent (afaik), or one of those reflective tops that look dark grey in daylight.
