    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: 33,601 ✭✭✭✭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'.



  • Registered Users, Registered Users 2 Posts: 9,015 ✭✭✭Markcheese


    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.



  • Registered Users, Registered Users 2 Posts: 2,323 ✭✭✭mrslancaster


    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: 6,240 ✭✭✭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: 9,552 ✭✭✭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: 8,212 ✭✭✭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.



  • Registered Users, Registered Users 2 Posts: 685 ✭✭✭wheelo01


    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, Paid Member Posts: 54,530 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.

    One needs to start hi-vis assembly lines to cash in 💡

    It is the policy of both the Government & RSA to recommend the use of high-visibility vests and armbands by vulnerable road users.

    In 2025 [sic] alone, the RSA distributed approximately 250,000 high-vis safety items including - high-vis jackets, high vis vests, high vis armbands, drawstring bags, rucksack covers and running bibs. In 2025 to the end of October approx 204,000 high vis safety items have been distributed https://www.kildarestreet.com/wrans/?id=2025-11-12a.591

    Cannot understand why this racket is allowed to continue.



  • Registered Users, Registered Users 2 Posts: 2,826 ✭✭✭Paddigol


    It's the easiest way to allow the various stakeholders to tell each other that they're being proactive in trying to improve road safety, without actually having to do anything to improve road safety. Buying their way to a clearer conscience essentially.



  • Registered Users, Registered Users 2 Posts: 6,587 ✭✭✭MojoMaker


    Buying your safety collateral from a company with a known connection to a board member of the RSA - have we no problem with this?

    Has it been rectified recently? I haven't stayed in touch with it.

    Its an interesting topic. High vis can't be a bad thing as I feel that anything that makes me slightly more visible to motorists is probably useful. However, I'll still go running at night dressed like the man from the milk tray ad and not give it a second thought if I am running on footpaths. My wife gives me an absolute bollocking when i get home dressed like that because she has concerns that i will get run over. I counter with the footpath argument - if a vehicle mounts the footpath whether i am wearing hi vis or not is not going to make a difference, and i am very aware when crossing roads / junctions etc. That said, last nights run was on some unlit back roads with no foot path so i was wearing a bright yellow jacket and had a good bright head torch on also. When i hear a car coming I stand in out of the way of the road fully expecting that they do not see me and i wait till they pass before moving on. Self preservation is paramount.

    When cycling i have lights on the bike, two front and two back, one flashing and one solid. I tend to choose lighter coloured cycling jackets and have a bright yellow gillet that generally goes over the top of whatever i am wearing. I generally avoid dark coloured jackets / jerseys but i do have one black jacket that i bought in decathlon cause it was a bargain. If i am wearing that one at night I will throw the yellow gillet over it. And also conscious during the day that it doesn't stand out like brighter clothing and adjust my road position / lights to accommodate.

    I see a lot of cyclists on weekend mornings heading past the end of our road on their spins and i would say about half would be dressed in predominantly dark clothing, which seems a little daft to me personally when you compare them to cyclists who are wearing lighter coloured clothing or high vis. The difference in visibility is remarkable. I fully agree that it is the motorists responsibility to ensure they are paying attention at all times and observing the road and the traffic, including cyclist and pedestrians, and driving appropriately for the type of road they are on. However, it seems a bit daft to dress in dark clothing, even during the day, when a lighter option makes you stand out a lot more and increases the chances of the motorist seeing you in lots of time. I regularly run the roads around kilcoole, newcastle, rathnew, etc with no footpaths and when doing so i take a lot of precautions - lighter clothing, waving at approaching cars, crossing the road at bends etc. Similarly, when cycling on narrower roads i give myself the best chance of being seen by not wearing predominantly dark clothing.

    Yes, drivers need to be better - pay more attention and get off their phones / devices. Equally, i'm going to ensure i do what i can to help them see me. I'm not going to wear white bib tights because that would be a crime and unnecessarily cruel to anyone who happened to look at me, but i'm certainly going to have some lighter / brighter / coloured top on to maximise my chances of getting home in the same state i set out. Sure, i might look cooler, faster, more svelte, dressed head to toe in black lycra, but I'd prefer to give the dozy motorists out there a fighting chance of seeing me before they crash into me.

    Mandatory - no, i don't agree that we should force all of the black clad cyclists / pedestrians to lighten up. Personal choice and responsibility. However i will make sure that if i am taken out of it by a motorist they won't be able to blame my clothing for the incident.



  • Registered Users, Registered Users 2 Posts: 6,587 ✭✭✭MojoMaker


    I'm not sure I agree. Under cover of darkness as a driver I can't see lighter clothing any better than darker clothing. What I can see is reflective strips and flashing lights - they are the only things that stand out without direct light shining upon them.

    During the daytime as a driver I find darker clothing much easier to see as it creates a much more discernible silhouette. The worst combo on bright/sunny days is light coloured and/or fluoro clothing.

    It's important to note that light coloured clothing is not the same thing as hi-vis equipment, which actively reflects light when illuminated in dark conditions.



  • Moderators, Sports Moderators Posts: 26,359 Mod ✭✭✭✭CramCycle


    I am now in he country so hi vis yellow is harder to see against a hedgerow during summer and during low in the sky sunlight conditions, in my opinion and observation.

    My lights on the other hand are visible at night and during low light conditions form a considerable distance. Sadly the buzz of HI Vis means that many think it is sufficient, and it simply isn't enough in these scenarios.
