According to jackie, according to jackie, the green light illuminates her before the red light because she is traveling toward the green light

I believe the answer is: 
The green light illuminates her before the red light because she sees the green light flash first
This most likely happen because  Jackie perceives herself as a fixed or stationary object, and both red and green lights are placed on the exact same distance away from her while the truth is that the distance between the two lights might be different.
