What Strategies are Used to Manage Ramp-based Traffic?
• Ramp metering – Controlling vehicles entering a freeway facility through the use of traffic signal(s) deployed on freeway entrance ramps. • Ramp closure – Controlling vehicles entering or exiting a freeway facility by restricting vehicles access to a ramp on a temporary, intermittent, or permanent basis. • Special use treatments – Controlling traffic and promoting the use of multi-occupant vehicles through preferential treatments given to a specific class of vehicle. • Ramp terminal treatments – Controlling traffic through improvements (e.g., signal timing, widening lanes, pavement makings, adding turn lanes, etc.) made at the ramp terminal. Ramp terminal strategies are often lower cost solutions that either seek to improve existing conditions, and/or maximize the benefits of other ramp management strategies like ramp metering.
