Dynamic lane-use control has been in use for over 50 years on arterial streets, freeways, toll plazas, bridges, and tunnels. One could say lane-use control signals were the first form of active traffic management. And yet, they are one of the least-researched traffic control devices in the Manual on Uniform Traffic Control Devices.
The TRB National Cooperative Highway Research Program's NCHRP Research Report 1021: Application of Dynamic Lane-Use Control: Proposed Practices presents a comprehensive, human factor study of dynamic lane-use control signal applications to provide advanced warning of closures in arterial and freeway operations.
