Portable Changeable Message Sign
Portable CMS

AEL/SEL Category 03OE-03-SIGN
Communicate critical info to motorists instantly. 
The programmable, trailer-mounted, solar-powered Portable Changeable Message Sign (PCMS) represents the latest advances in changeable message sign technology. With the ability to furnish timely, pertinent, and dynamic traffic information to the motorist via alphanumeric text and/or graphic displays, it provides the operator a measure of traffic control, incident management, and congestion mitigation unmatched by other signs.

Capable of displaying one-, two-, or three-line alphanumeric messages (each line comprised of eight individual display panels), the sign is capable of displaying a library of graphic messages consisting of Manual on Uniform Traffic Control Devices Part VI arrow board functions. The PCMS has the memory capacity to retain 199 programmed messages, 199 user-generated messages, and 250 message sequences (up to six messages / sequences).

The brightness, or intensity, of the LED portion of the display may be controlled manually, or alternatively may be regulated automatically via a photosensitive circuit that adjusts the LED intensity in response to ambient illumination, thus assuring superior visibility and legibility under all lighting conditions.
The trailer-mounted sign may be operated remotely through the use of central host software to provide compatibility with existing ITS systems. Options include, but are not limited to, landline, cellular, and CDPD/TCPIP (Internet Protocol). Additionally, the sign may be used in traffic calming/speed awareness applications via an optional radar interface that makes it capable of not only displaying cautionary messages, but also actual vehicle speeds that exceed a user-programmable threshold.

Portable Changeable Message Signs qualify for certain FEMA fire protection and safety grants.
