This is an interactive web map of the eight-county OKI region around Cincinnati, Ohio. Each point plotted on the map marks the location of a traffic counter and shows the Average Annual Daily Traffic (AADT) — the typical number of vehicles that pass that location on a given day. Use the map controls or your keyboard to pan and zoom; the number of points shown updates as you move and zoom the map. Selecting a point opens a detail popup with three tabs: an Info tab listing the location, AADT, count year and data source; a Counts tab with a yearly table of traffic volumes broken down by direction and by trucks; and a Charts tab graphing traffic volume by hour of day. You can download the data for an individual point from its popup, or download data for a county or a custom selection from the Data panel. Because only up to 500 points are shown at once, zoom in for more detail in busy areas. If you cannot use the map directly, the same data can be downloaded as CSV files from the Data panel in the menu.
