Active traffic management (ATM) aims to dynamically manage recurrent and non-recurrent congestion based on prevailing and predicted traffic conditions. Researchers analyzed the effectiveness of the US Route 23 Flex route opened by Michigan Department of Transportation (MDOT) in 2017 to mitigate peak-hour congestion, reduce incident response times, and improve safety. The Flex route uses the corridor’s 11-foot wide inside shoulders as dynamic lanes over a length of 8.5 miles. Researchers analyzed the performance of the Flex route, the safety of the adjusted roadway, driver perceptions, and the costs and benefits provided. Operational performance data was collected using various sources including probe vehicle data, microwave vehicle detection system reports, permanent traffic recorder data, ATM reports, and incident clearance data. Real-world safety data was collected before the lane was installed, from 2012 to 2015, and after, from 2018 to 2019.
