Traffic Light Scam II

More on the Italian traffic light scam. I wrote to Mr. Arrighetti asking for comment, and received this from Silvia Guelpa, who says she is a consultant to the company. In summary, she’s arguing that the company, and its founder Stefano Arrighetti, haven’t done anything wrong and that if anyone has broken the law it’s the companies and police who have been responsible for changing the settings which created the huge volume of tickets.

She makes the points that

  • KRIA is a manufacturer and does not sell to the City Councils but to Companies who rent the T-RED to the Police with contracts based on the number of ticket (about 30%).
  • T-RED—the system–does not actually control the traffic lights, which are managed by a controller.
  • T-RED can be configured to detect immediately after the red phase begins or after a configured delay (0-10.000ms). Local Police and Companies renting the systems set the yellow on the controller for as short a period as possible and reset to zero the above mentioned delay, in order to increase the number of tickets.

This, she says, is what is causing the abnormal number of tickets.

She also says there has already been one investigation, by Milan’s attorney, which concluded after one year that KRIA is “absolutely innocent and out of any private interest.” That investigation, she says, resulted in the arrest of “bosses of the companies buying and renting T-RED and they admitted that they forced and won many tenders incorrectly.”

But with public outcry still strong—three million tickets still had to be paid—Verona’s attorney started investigating KRIA’s certification—whether or not its system had all the right paperwork. The idea, she says, was to find an excuse to cancel all the tickets.

KRIA believes it has all the right certification, arguing that the only parts which need to be certified are “the fixed, immutable components of the device”–cameras, lighting systems, PC and PCI board. But Ms Guelpa says the attorney’s power “is unlimited during the investigation phase. They can even arrest people.”

Her argument is basically that Mr. Arrighetti is being made a scapegoat on a technicality.

Lesson from this? I guess I’m still reeling from the idea that police forces would fiddle the system to fill their coffers, not just in Italy but elsewhere. But I guess the bigger point is that all kinds of technology are susceptible to this kind of manipulation, which raises the question: Quis custodiet ipsos custodes?

The Traffic Light Scam

If true, this is a scam that is going to fuel the conspiracy theories of every driver who feels they were fined unfairly for crossing a red light. Police in Italy have arrested the inventor of a smart traffic light system, and are investigating another 108 people, on suspicion of tampering with the software to speed up the transition from amber to to red, netting the local police and others in on the scam millions of dollars of extra fines.

The question is: Is this kind of thing limited only to Italy?

The Independent writes:

Stefano Arrighetti, 45, an engineering graduate from Genoa who created the “T-Redspeed” system, is under house arrest, and 108 other people are under investigation after it was alleged that his intelligent lights were programmed to turn from amber to red in half the regulation time. The technology, which was adopted all over Italy, employs three cameras designed to assess the three-dimensional placement of vehicles passing a red light and store their number plates on a connected computer system.

Those now under investigation include 63 municipal police commanders, 39 local government officials and the managers of seven private companies.

The fraud, The Independent says, was uncovered by Roberto Franzini, police chief of Lerici, on the Ligurian coast, who – in February 2007 – noticed the abnormal number of fines being issued for jumping red lights. “There were 1,439 for the previous two months,” he said. “It seemed too much: at the most our patrols catch 15 per day.” He went to check the lights and found that they were changing to red after three seconds instead of the five seconds that had been normal.

Unanswered, of course, is why it’s taken two years for the fraud to be stopped and investigated. The inventor’s lawyer has said he is innocent. Mr Arrighetti’s LinkedIn page is here. He is described as the owner of Kria, a Milan-based company which sells the T-Redspeed and other traffic monitoring systems.

The T-Redspeed system is described in the company literature as “the newest and most innovative digital system for vehicle speed and red light violation detection. Based on special video cameras, it doesn’t require additional sensors (inductive loops, radars or lasers). It measures the speed of the vehicles (instantaneous and average) up to 300 km/h.”

Some forum posters have suggested a system used by British authorities, RedSpeed, is the same, but on first glance it doesn’t look like it. That said, reducing the amber phase seems to be a widespread source of extra revenue: The National Motorists Association of America has found six cities that have shortened the amber phase beyond the legal amount, apparently as a way to increase revenue.
