Safe Speed Forums

Not sure if it's been picked up here but this project has been concluded & results published (September 08) here:
http://www.dft.gov.uk/pgr/roads/vehicle ... daptation/

I don't expect it to get an unprejudiced reception here but am sure you'll enjoy debating it to death

I'd have been impressed if the motorcycle tests had been done on roads and not a test track.

Am I missing the point? My car currently has Intelligent Speed Adaptation fitted to it every time it is driven - me!

This scheme is NOT intelligent, it is passing important speed decisions away from the driver, who by law has to undergo a minimum level of training, to a machine which abitrarily limits the speed of the vehicle based upon the speed limit. This is not intelligence, it is the very opposite.

If this goes ahead then I can see the number of KSi's going through the roof.

did you actually read the definition then ?

This is not a good idea. We want their money. Warning them will only work if we are warning them so constantly, that they tire of the warnings and ignore them, thus ensuring our income.This is pointless. Presently, we set the speed limits low enough so that they can't help but to break them at least as often as they do now. Allowing the driver to override the posted speed 'limit' is what we are already doing. We would be spending money to allow drivers to avoid giving us money, so this is right out.This is an interesting idea. This would effectively create a mass transit system, using everyone's personal vehicles. Since we would be giving up the revenue generated by speeding violations, we would naturally have to increase the purchase and maintenance costs of the personal vehicles going forward to include and 'maintain' the additional technological load required - as we have done in the past with other 'safety features'.Your amygdala and your gut will provide sufficient information here; ignore all scientific facts and figures, especially the majority of it, which contradicts what we insist on calling "the known relationship". If your gut is right half of the time, why not just trust your gut all the time? We have more important things to spend other people's money on, so we can get it back.
The initially expected measure of benefit of nearly every safety feature that has ever been invented has been never been fully realized by their users, a phenomenon which a researcher by the name of John Adams terms
'Risk Compensation'.

Seatbelts, antilock brakes, and all other 'safety features' are either mitigated to varying degrees by the users, or are themselves attempts to circumvent either the user's risk compensation[s], or other driver shortcomings (I.E.: Emergency Brake Assist circumvents both those drivers who respond to ABS pulsations by backing off brake pressure, and those who simply can't or won't step on the brake hard enough in the first place).

Cutting to the chase, ladies and gents, Intelligent Speed Adaptation provides us with a quandry.
Up until this point, we have depended upon the statistically normal behavior of the public to regulate their own travelling speeds, resulting in a windfall which largely is the reason why we are able to discuss ISA presently.

I submit that if we properly implement ISA, we can both save more lives, and increase revenues for all involved parties. If not, there exists a serious possibility that we might neither save lives, nor profit.

The Rules for ALL ROAD USERS:
1) No one gets hurt
2) Nothing gets hit, except to protect others; see Rule#1
3) The Laws of Physics are invincible and immutable - so-called 'laws' of men are not
4) You are always immediately and ultimately responsible for your safety first, then proximately responsible for everyone's
Do not let other road users' mistakes become yours, nor yours become others
5) The rest, including laws of the land, is thoughtful observation, prescience, etiquette, decorum, and cooperation

All of which will be useless unless Galileo gets "on the road"
The current gps system has large blank spots, and many of the posted limits are changed so often that the ISA database [in car] would need updating
every few hours.
Note also that the system does not start at the speed limit, but at a "zone" NEAR the limit



Yes, as if.



[translation] We would have to remove older vehicles from the vehicle pool eventually[/translation]



How about the potential for isa equipped vehicles to CAUSE the accident by slowing-down BEFORE the posted limit starts, or when the posted limit is higher than the stored limit ?



Rather a lot seems to be either assumed, or relies upon models.
How accurate can something be when it produces different results when used [for instance] in a 30mph scenario when it was developed for a 20mph scenario ?

I can see I'm going to have to read through the whole bundle carefully. But, much seems to be approximated or based upon computer models. Like the global warming models ?
