Safety Considerations
Consideration should be given to the effects of the installation on all road users, not just those in four wheeled vehicles. Three wheeled vehicles, motorcycles and vehicles with trailers, for example, may not be sensed by the vehicle detectors used with automatic bollard systems. It will almost certainly be necessary to provide alternative means of access for some classes of road users or vehicles.
The possibility of a device rising under a wheelchair or pushchair should be taken into account. The risks could be mitigated to some extent by providing suitable alternative access adjacent to the bollards, and by using a coarse road surface to divert pedestrians away from the bollard installation.
Whilst most applications will be to enable the passage of one vehicle at a time, there will be instances where two or more vehicles attempt to pass through in close succession. The system should ensure that bollards cannot rise beneath a vehicle because of the danger this would create. It is better to risk a certain amount of violation by "tailgating" vehicles, rather that put road users at risk.
Any system, however well designed, will fail to operate correctly on occasions. The system should fail to a safe state, ideally with the bollards retracted. In the event if an accident the emergency services may need to override the control system and retract the bollards.
I think I will e-mail this to the Manchester paper .. Ta!
You know .. not all ambulances are the typical van. Some are estate Mondeos, Vectras and BMW. These vehicles are also at risk from this stupidity of a bollard which even appears to have difficulty "sensoring a big bus"

Ambulances are especially vulnerable in this daft system. What if a shopper has a heart attack in the M&S .. Boots or within St Anne's Square - which I know is near the M& S Manchester store.?
My view .. they should remove these things and use an electronic gate - which can be opened by bus/taxi/emergency vehicles and all the biking paramedics.
I have an electronic gate on my own property. I've never had intruders nor unsolicited calls since I installed it. I have intercom and a close circuit TV as well. It works fine.. and - um - some people might think our gate opener does some other things.
Our youngest

bless her
loves playing with this
I honestly do not know if she plays with it near Steve's vans ..

nor have I faintest idea if this "affects" anything either

though we did note that all automated shops doors seemed to have a bit of a turn once when the littlest one was fiddling

once
I have since updated my post in which I got the scanned images to small to see. I think the corrected images show the sheer unsafe stupidity here.
