Maybe!

I might question the benefits of making the poor area even poorer via fines they likely can't afford. I might wonder if there are confounding factors like poorly maintained roads and vehicles at play. I might wonder if the yellow lights have the same timing as in the suburbs.

Are the small fines for red light violations costlier, or the impact on health and life from the collisions red light running inevitably causes? I think letting poor areas be high traffic injury areas through deliberate neglect is even costlier to the poor who live there than red light fines.

[whimsicalism]

I might question why you are so opposed to interventions that save the lives of people in poorer neighborhoods (disproportionately not owners of cars).

I question the premise that it will.
