Denver has failed to enforce its red-light camera contract, collecting $75 fines but not collecting the data necessary to determine whether the program actually is reducing red-light running, reports the Rocky Mountain News. The contractor, Redflex Traffic Systems of Scottsdale, Az., hasn’t submitted a single page of the mountains of data the contract requires since the cameras went live last summer, including statistics that would disclose whether it must reimburse money for system failures. The Denver Police Department failed to demand any of the required reports until a Rocky Mountain News Open Records Act request showed there weren’t any to be found.
More than 11,200 tickets were mailed out through November. The raw data that is available lends credence to standard traffic engineering practice outside Denver that increasing yellow-light timing reduces red-light running. After the newspaper reported that Denver uses the legal minimum three seconds of yellow, despite an engineering formula calling for more, the city agreed to add time at all four camera locations. According to police data through November, at three of the locations where the yellow was boosted to four or five seconds, a daily average of nine, 10 and 16 tickets are issued. That’s significantly less than Redflex studies at those locations last year, when the yellows were three seconds.
