Abstract

This paper examines factors that affect the ability of drivers to recall Portable Changeable Message Sign (PCMS) messages in highway work zones. A Chi square analysis has found that the time of day, driver's age, type of vehicle, and familiarity with the site are relevant factors, and that drivers were more likely to recall messages that contain action rather than problem statements. A regression analysis revealed that drivers recalled the PCMS message components that they desired to see almost twice as often, and that drivers familiar with the construction site were almost twice as likely to observe an action statement.
