Safer Work Zones Through ITS

The Florida Department of Transportation has developed an Interim Traffic Management System (ITMS) to address congestion on I-95 during its eight-year construction project affecting 46 miles. This system is designed to be rapidly deployable, mobile, and reconfigurable, promoting safety through effective traffic management. Key features include real-time information dissemination, dynamic message signs, and data capture for incident tracking. Evaluations assess public perception, partner agency feedback, and the operational effectiveness of the ITMS in reducing travel delays and crashes.
