Lane control signs, supported by surveillance and detection technologies, allow the temporary closure of lanes to avoid incidents on freeways.

Simulation shows an optimized CAV control framework can increase the effective capacity of high-volume corridors.(3/18/19)

Simulation shows V2I applications that use real-time traffic data to recommend merge maneuvers can increase throughput 18 to 22 percent compared to existing systems that use message displays on overhead gantries.(01/13/2019)

Part-time shoulder simulated to decrease travel time by up to 1.86 minutes per kilometer along congested segments of Philadelphia interstate.(11/21/18)

An Active Traffic Management System (ATM) on I-66 in Northern Virginia reduced total (all severity), multiple-vehicle (all severity), and rear-end (all severity) crashes, 6 percent, 10 percent, and 11 percent, respectively.(10/01/2018)

In a recurring congestion scenario, ramp metering, variable speed limits, and hard shoulder running found to improve corridor travel time and network performance by 5 to 16 percent. (09/01/2018)

During an incident, motorists can see up to a 50 percent savings in travel time with MDOT’s Flex Route lane control system.(11/13/2017)

Collisions on I-5 in Washington State have been reduced by 65-75 percent in a 7.5 mile corridor where an active traffic management system was deployed.(November 19, 2010)

Simulated deployment of Integrated Corridor Management (ICM) technologies on the I-394 corridor in Minneapolis show a benefit-cost ratio of 22:1 over ten years.(November 2010)

Speeds in general purpose lanes slightly increased with the implementation of HOT lanes.(November 2006)

It was estimated that variable speed limit signs and lane control signals installed on the autobahn in Germany would generate cost savings due to crash reductions that would be equal to the cost of the system within two to three years of deployment. (August 1999)

Advanced traffic management systems in the Netherlands and Germany reduced crash rates by 20 to 23 percent.(August 1999)
