The Michigan Department of Transportation (MDOT) presently manages a project for providing operational control and service for a portion of the freeway system within the city of Detroit. This Detroit freeway operations group is well known as the Surveillance Control and Driver Information (or SCANDI) System. The project consists of four subsystems; Motorist-Aid Telephones, Changeable Message Signs, Television Surveillance, and Ramp Metering. The benefits from ramp metering are more than anticipated and could be even greater with revisions to the metering plan. The television surveillance operation is performing adequately in detecting freeway incidents along critical sections of the Ford Freeway. The motorist aid telephones are used fairly extensively despite their poor condition and limited reliability. The changeable message signs cannot be properly evaluated because of their very poor visibility, but we believe they should play a role of informing the motorist as part of an incident management plan.
