Policy Implications• There is a large gap in air quality monitoring.

• Air monitoring station locations must be mandated to be near highways

Skills Used• Modeling• Measurement• Original Data (air monitoring stations)• Hot Spot Analysis• Network Analysis (Closest facility)• Chart• Buffering• Inset Map• Select by attributes (major highways derived from all highways and selected by FCC

category of A15)

• Geocoding
