The use of late night (off-peak) flashing operations was evaluated as part of previous phases.
As it currently stands, Lincoln does not implement late night (off-peak) flashing schedules for the signals. The industry has leaned away from this in recent years, based upon recommendations from Federal Highway Administration (FHWA) regarding safety concerns.
It comes down to a benefit/cost issue. The bottom line is there will be many updates to signal operations resulting from Green Light Lincoln, but they will be data driven, and based upon best practices, and latest industry standards.
