ERJ staff report (DS)
London -- A new technology is available for measuring tyre pressure as well as tread-depth on moving vehicles. The ProContour system uses lasers and cameras to measure tread depth as a tyre passes over a sensing unit.
Data can then be sent to a team waiting further down the road who then have the option to stop vehicles with illegal or near-illegal tyres.
Each unit costs around Â£43 000 (euro 50 000). The system is temporarily fixed on the road surface and is capable of measuring, all at normal traffic speeds:
Wear pattern (indicator of potentially dangerous chassis damage)
Tread type (differentiation between summer and winter tyres)
UK press reports have suggested that the UK police are investigating this as a possible technology for law enforcement, but a spokeswoman for the Association of Chief Police Officers (ACPO) said it is unlikely the UK would deploy the system as the data is not admissable in a court of law and the system is prohibitively expensive.
She said this is one piece of technology among many which one of their consultants observed as part of his brief to keep up to date with current developments.
