+# DAC Traffic Impacts CSIS Metric
+# Pseudo Code
+
+# For projects in list:
+  # Sum AADT values across segments (i.e. peak/off-peak, HOV/non-HOV)
+  # Repeat for truck AADT
+  # Apply a weighting factor of 6 to the truck AADT
+  # Sum car and weighted truck AADT to get AADT value
+  # Repeat for both build and no-build scenarios
+  # Calculate the percent change in truck-weighted AADT
+
+# Join the build and no-build AADT data to the project spatial geometry on the project name field
+
+# Generate a 500 meter buffer for all project geometries
+
+# read in EQI Traffoc Exposure Screen
+
+# If the project geometry buffer DOES NOT touch an EQI Traffic Exposure Screened geography, the project score defaults to 0
+# Else If the project geometry buffer DOES touch an EQI Traffic Exposure Screened geography, the change in truck-weighted AADT is considered and a relevant score is determined.
