After downloading and opening the KMZ file, please note the turning movements are organized by year.
- Zoom in to the intersection you are seeking. The number in the colored hexagon symbol indicates the year that turning movement data is available.
- Click on the hexagon and a pop-up dialog will appear with summary information about the intersection. Some intersections may have multiple years of data and clicking on a hexagon will result in a symbol for each year that data is available.
- Click on the link at the bottom of the dialog window to view a PDF diagram of the intersection with turning movement
data. New roadway and intersection relocations may cause dots for older turning movements to appear off the
current location of the roadway. Google Earth's historical imagery tool may allow you to view the former
alignment of the roadway.
