Global Warning Signal Integration as a Tool for Work Zone Safety and Efficiency

In this two-part study, the authors investigate ways for making the overall visual appearance of a work zone more compatible with the needs of passers-by. In the first part, psychophysical tests were conducted to assess the effect on lane keeping ability when the work zone signals were ignited synchronously, as opposed to asynchronous ignition. In the second part, the authors investigated the feasibility of using wireless communication to coordinate light ignition times and to create coherence among the warning lights. Addition consideration was given to the feasibility of triggering the signals in sequence to create a visible pattern that is instructive to the passing driver.
