PAVEMENT MARKINGS as an alternative to red-light cameras:

New research sponsored by Florida’s Department of Transportation suggests a number of effective engineering alternatives can reduce red light running. Using an advanced driving simulator to monitor the reactions of ordinary drivers, University of Central Florida researchers concluded that improving street markings near intersections reduced red light running by 74 percent without increasing the likelihood of rear end collisions.

“The pavement marking countermeasure is a low-technology and inexpensive solution to reduce the number of motorists that run red lights,” the study concluded.

On the other hand, it’s not a source of revenue.

UPDATE: By comparison, traffic cameras increase accidents according to this Virginia study. But they also increase revenue!
