• Abstract:
  Ramp metering is a traffic management tool used to increase the efficiency and safety of the ; traffic operations on freeways. It is one of the most cost effective ways of managing traffic flow. ; It improves traffic flow on congested freeways and often significantly delays the necessity of ; undertaking major freeway improvement projects. ; Freeway ramp meters are traffic signals installed on the freeway on-ramps to regulate the traffic ; entering the freeway system. Ramp meters allow the traffic to enter the freeway at a rate ; dependent on the conditions of freeway mainline traffic. They generally operate during the traffic ; peak periods. The main objective of ramp meters is to maintain the freeway traffic volumes ; below the freeway capacity, and to provide an acceptable level of service. In highly populated ; metropolitan areas, this objective is difficult to maintain for long periods of time due to high ; freeway and on-ramps traffic demand. Stop and go traffic conditions are normally delayed and/or ; shortened and congestion related traffic accidents are highly reduced. ; Freeway ramp meters are often used in conjunction with preferential High Occupancy Vehicles ; (HOV) non-metered lanes in District 7, to provide time saving incentives for use of carpool, ; vanpools and public transit.
