Other Traffic Counts Other sources of traffic counts that are currently available include screenline, city, bordercrossing, and SCATS counts. SEMCOG has the screenline counts stored in an Access database similar in structure to the county databases Data from the Cities of Monroe, Farmington Hills, and Southfield are added to the RTCD. SEMCOG has details about the structure of the border-crossing and SCATS data and is looking to transfer this data to the RTCD.
