Highway Screening Analysis Tool - Google Earth map tool to identify estimated risk and hazard impacts from highways throughout the Bay Area.  Google Earth must be installed to run files. Click on different segments of the highways to view estimated risk and hazard impacts that represent the average annual daily traffic (AADT) count, fleet mix and other modeling parameters specific to that segment of the highway.  The estimated risk and hazard impacts were modeled at two different heights, 6ft. and 20 ft.  The 6 ft. height estimates should be used when receptors are located on the ground floor of a building; and the 20 ft. height estimates should be used when receptors are located on the second floor of a building.
