MUTCD code search interface


mutcdcodesearch.png This program provides the database interface to search the Manual on Uniform Traffic Control Devices codes. Each sign image is excerpted from the PDF manual. Users can specify the search option at the Query options box. The properties of each sign will be displayed when a user select a sign. Additionally, to see all signs in the database (currently 667 types), press Show all signs at the bottom of the query window.

Operating system

I developed this software on Windows XP.


Once you installed the program, you have to modify the mutcd.ini file located under /mutcd/data/mutcd.ini to meet with your directory configuration. Specifically, basedir and datadir should be modified. Followed the format in there.

Open mutcd.ini with any text editor. Modify the directory in there
