the location of the sensor for going the speed limit
Unfortunately, placing sensors that far back from the intersection is costly, both in initial installation and maintenance. Most sensors in the US are right at the stop-lines for the intersection only (with frustrating effect when an overly light scooter or other phenomenon stops the sensor from sensing a vehicle).
