The Congestion Toolbox is a comprehensive collection of tools that can be used to measure, manage, reduce and alleviate congestion.  These tools include access management, corridor planning, managed lanes, ramp metering, roundabouts, traffic signal coordination, land-use planning and many others.

Access Management is the careful planning of the location, design, and operation of driveways, median openings, interchanges, and street connections.  The purpose of access management is to provide access to land development in a manner that preserves the safety and efficiency of the transportation system.

Roundabouts is one type of intersection that may be used to improve safety, reduce congestion, calm traffic and improve aesthetics.
