Traffic Data - Traffic AADT Maps
If you are working on or contracted to do an MDT project, do not use traffic data from this map. Please continue sending your formal traffic data requests via .
Welcome to MDT's Interactive Traffic web map!
Please utilize this map if you are looking for Annual Average Daily Traffic (AADT).
The Traffic web map contains a basemap, a set of data layers, which include interactive pop-up windows with information about the data, and navigation tools to pan around and zoom in to the map.
There are multiple layers of information being displayed on the map therefore you must zoom in to see detail such as the traffic count location sites. Once zoomed in, the map displays a point and a line layer containing AADT’s collected at those points and the line segments referenced to those collection points.
Click on the features in the map to display details. The pop-up box displays data in multiple slides – scroll through the slides using the arrow at the top of the box.
If you would like to view more detailed traffic data, please visit our traffic count database system (TCDS).
