|Mn/DOT Traffic Data|
|DataTools Index||March 07, 2014|
The Minnesota Department of Transportation collects traffic data on the freeway system throughout the Twin Cities Metro area. This data is archived and made available to the public via our data tools, DataExtract and DataPlot.
DataPlot is a tool for graphing detector data.
DataExtract is a tool for extracting detector data to a csv file for analysis.
The All Detector Report can be used for locating detectors and stations.
It is recommended that you have at least 64 MB of RAM to run either application, preferably more. They have been tested on Windows 2000, Windows XP and Linux, but should work fine on any operating system which supports a current version of Java (1.6).
These applications require unrestricted network and PC access. By design,
Java Web Start restricts this access. You will be prompted to
allow unrestricted access but advised not to do so. Disregard
this advise and click the "Start" button to allow access.
The applications require the Java Runtime Environment 1.6 or higher. If you do not have it, you will be asked to install it. This must be done by
someone with local admin privileges. If you attempt to install
it without proper privileges, the installation will fail and you will
get a "bad installation" error. When successfully installed, you may start up the Java Web Start Application Manager and run it from there.
If the calendar dates are all grayed out, it is likely because the
application can't communicate with the traffic data server. If you are
behind a corporate firewall, please make sure that
TCP port 8080 is open.
