Most traffic signal lights within the City of Spokane are controlled and monitored by a central computer located inside the Operations Complex. The computer adjusts the signal timing and coordination to match the predominate traffic patterns on the City's arterial roadway system which is primarily determined by historical data obtained by frequent vehicle traffic counts. As a general rule, traffic flow is optimized for inbound directions in the morning and set for outbound patterns in the afternoon.
