This trap is a result of a program Livonia put into effect called STAR I am unsure of what the acromym means but I kno it has something to do with enforcing intersections in Livonia during busy days and the cops sit in parking lots around the intersection and will gun people and a car down the street will write people up it varies between north and southbound traffic they are also very strict on running the red light and which is a problem because the light goint North/South on merriman is green for about 30 sec
