Signal Plan Locator
This tool is designed to help you find digital copies of the traffic signal plans.
The files are available in PDF as well as TIF format. The latter
can be used as reference within a MicroStation file.
Please read the materials in the help section to
get acquainted with the operation of this tool.
Keep in mind, that the size of each file may be anywhere from 100 KB to 5 MB.
Depending on your connection speed you might experience some delay in opening the files.

Maryland Signals on the Map
Google Earth users can download the GIS version of Signal Plan Locator
and view it as a map along with other geo-coded information. Once the file is open, you will notice
the signals are sorted by county. You may access the plans for each signal by either clicking
on the signal icon or the corresponding item on the left. A pop-up window will appear on the map with a link to the plans
(if they are available for that location). Please note: you may have to adjust the settings in Google Earth if you would
like the plans to open in a separate window. We will post a new version of this file with every update.
We depend on your feedback to improve the quality of our products. If you find any errors
in the way the documents are presented, or have a suggestion concerning the operation of this program,
please e-mail the Traffic Engineering Design Division of Office of Traffic and Safety at: LLiang1@mdot.maryland.gov.
