摘要：	This study was conducted to verify the compliance of vehicular and pedestrian LED traffic signal modules with the Institute of Transportation Engineers specifications; and to assess drivers preferences of the LED modules. Four vehicular modules (ACS, Dialight, Leotek, and Lumination) and three pedestrian LED modules (Dialight, Leotek, and Lumination) were used. The compliance verification primarily involved reviewing the independent-lab testing reports, visual inspection of the modules, and analyzing the manufacturers responses to the questionnaires prepared by the research team. The solid LED modules provided by ASC had several issues with compliance with the ITE specification; however, the modules from other companies either complied or complied with reservation with all the ITE Specifications. No general conclusion were made for the arrow modules since at the time of completion of this study, ITE had not adopted a final specification for them. For pedestrian modules, all companies submitted independent lab test reports for some of the modules, but not for all. The reports showed that all these modules either complied with, or complied with reservation with most of the ITE specifications. To assess drivers preferences, 120 drivers participated in the evaluation of the modules.
