Ramp metering is commonly used in major metropolitan areas to reduce freeway delay and improve safety. It does this by 1) smoothing the flow of traffic at the merge and thereby increasing effective freeway capacity and safety and 2) reducing the traffic entering the freeway which reduces the volume to capacity ratio. Topics covered by this chapter include:
Ramp meter physical installation requirements and ranges of metering rates.
Traffic flow breakdown models and the role of ramp metering in improving breakdown.
Ramp metering strategies including pretimed, traffic responsive, isolated and systemwide ramp metering.
Ramp storage requirements and ramp queue control strategies.
Ramp metering acceptance by the public.
Ramp metering benefits model.
