Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2005 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, researchers document the development of a field guide for portable changeable message sign use in work zones. Included in the report is a summary and critique of available national and state-level standards and guidance on portable changeable message sign (PCMS) use, description of the components included in the field guide, and implementation considerations for field guide deployment. The field guide was developed as a stand-alone product, but is included for illustrative purposes as an appendix to this report.

This book was released on 2005 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, researchers document the results of a laptop-based human factors study of alternative formats of presenting advance notice work zone information on portable changeable message signs (PCMSs) and a Texas Transportation Institute (TII) driving simulator study of the ability of motorists to capture and process information on two PCMSs used in sequence to convey information about upcoming traffic situations. Based on the studies, researchers recommend that messages that require the display of calendar dates for future roadwork and other traffic control activities should utilize a message format consisting of the three-character abbreviation of the month (e.g., APR for April) in conjunction with the date. When future work activities span several days all in the same month, the month needs be noted only once in the message (i.e., APR 21-23) rather than repeating the month (i.e., APR 21-APR 23). The ITI driver simulator study results indicate the need to keep overall messages at or below the four-unit maximum recommended in existing guidelines. Researchers found that presenting five units of information on sequential PCMSs resulted in low comprehension rates, below what would be acceptable for highway applications. However, by keeping the message length to four units, it does appear that the use of sequential PCMSs will result in comprehension rates comparable to those obtained by presenting the same information at a single location on a large dynamic message sign (DMS), and is recommended as an acceptable formatting approach for TxDOT. Comprehension may be enhanced by repeating one of the units of information on both PCMSs.
