UTC 2022 Funding - Cycle 2 Research Projects

Project Number: CY2-OSU-09
Project Title: Study the Effectiveness of ODOT’s Initiatives in Construction Work Zone Safety
Performing Institution: Oklahoma State University
Principal Investigators: Yongwei Shan and Joshua Li
Proposed Start and End Date: 10/01/2024 to 09/30/2025
Project Description: Work zone safety is a critical concern for transportation agencies, as work zones present numerous hazards such as narrowed lanes, lane shifts, and the presence of construction equipment. Speeding in construction work zones can lead to crashes that result in both fatalities and injuries for construction workers and drivers. The Oklahoma Department of Transportation (ODOT) has implemented various initiatives, including variable speed limits, Smart Work Zones, and the "Operation Hard Hat" program, to enhance work zone safety. However, the effectiveness of these initiatives and the factors influencing drivers’ compliance with speed limits in work zones require further investigation. This research project aims to evaluate the effectiveness of ODOT's current initiatives in promoting safe work zones and to identify the key factors that affect drivers' compliance with speed limits within these zones. The project will also address inconsistencies in how speed limits are applied across different districts and contractors, to develop clear, consistent guidance and policy to improve work zone safety statewide.
