Intellizone--WI

Status: Complete

Description: Intellizone is a product for giving advanced warning to drivers of slowing traffic entering work zones. Intellizone consists of a series of microwave detectors and portable message signs, linked together by wireless communication. The study site was the northbound direction of US 41 in Green Bay, Wisconsin, which underwent lane closures. There were two sources of data for evaluating the effectiveness of Intellizone: the Intellizone detectors and a questionnaire administered to drivers who had just passed through the work zone. Drivers were generally satisfied with the speed advisory signs and most drivers felt that the signs were accurate.
