"A before-and-after analysis of photographic evidence and interviews with experts suggests the transition to a new vendor last spring was accompanied by a subtle but significant lowering of the threshold for yellow light times," reports David Kidwell.

"City hearing officers have noticed the trend and are increasingly tossing tickets because the yellow light time stamped on the citation is less than the 3-second minimum required by the city, the Tribune analysis showed."

Xerox State & Local Solutions took over the program in March after a bribery scandal brought down the previous vendor, Redflex Traffic Systems, Inc.
