The objective of this study was to develop and test word and symbol traffic control and hazard messages for portable changeable message signs (PCMSs). The messages were designed for the standard PCMS with three lines of eight characters. First, a comprehensive listing of candidate PCMS messages was developed. This was done by interviewing State highway engineers, surveying PCMS manufacturers and questioning motorists. In those situations where subjects did not express an overwhelming sign preference additional field testing was done. The detection distances of the candidate messages were determined using a PCMS under both day and night conditions.

Portable Changeable Message Sign (PCMS) systems used in work zones are programmable supplementary traffic control devices that display messages composed of letters, symbols or both and provide information and instructions to the traveling public approaching work zone activities. The study seeks to develop warrants and criteria for PCMS deployment in Illinois highway work zones. It is recommended that PCMS systems be used during long- and intermediate-term stationary work, for traffic control through incident areas, and in projects where advance-time notification is needed. The discussion focuses on spacing criteria, number of signs required, sign visibility and message legibility, text alignment, distance criteria, message length, duration and type, project-level operational guidelines, message storage and dissemination, repair, maintenance and utility costs, as well as control and coordination issues. The study concludes that additional research is needed in order to: develop a comprehensive standardized statewide database of messages and message abbreviations; develop a comprehensive repository with information about the technology of the various components of the PCMS units; coordinate PCMS units used in highway work zones with a corridor or regional ATMS system; and maintain information about the use of a PCMS unit in a work zone project and possibly integrate it with other relevant information in a management system.
