Semi-Automation of Interstate-90 Variable Speed Limit (I-90 VSL) Corridor in Ohio's Advanced Traffic Management System (ATMS)

The current process to adjust speeds on the corridor includes utilizing various data/tools such as speed sensors, CCTV cameras, road weather information systems (RWIS), and communications from local authorities. A Statewide Traffic Management Center (TMC) Specialist has to manually monitor the information from the sources then make a decision as to whether speeds should be adjusted in the corridor. Ohio Department of Transportation (ODOT) would like to remove the subjectivity of this process by creating a set of thresholds/criteria to change speeds based on data-driven research. The goal of this research is to provide data-based decision support in a semi-automated fashion to improve the efficiency and effectiveness of managing the I-90 Variable Speed Limit (VSL) Corridor.
