Disabled parking reminder system

A disabled parking reminder system is a motion detector sensor which produces an loudspeaker announcement when a motorist attempts to park in a dedicated parking bay for persons with a disabled parking permit. The purpose of the system is to deter non-disabled parking permit motorists from taking up these spaces.

Spacehog
In 1996, the United Kingdom firm Disabled Parking Systems Ltd developed a system called Spacehog, a bollard containing sensors with radio transmitters which communicate information to electronics in nearby audio signs. The technology was employed in leading chains such as Asda and B&Q. By August 2005, Asda would roll-out 4,000 Spacehogs at more than 150 stores.
