Ramp metering (Traffic engineering)

found: Work cat.: Das, A. Assessment of ramp metering strategies, 2005:abstr. (Freeway ramp metering systems have been successfully used in the United States since the 1960s to improve traffic flow ... These systems improve freeway flow by regulating the rate at which vehicles are allowed to enter the freeway at the entrance ramps)

The proceedings of the 2003 IEEE International Conference on Intelligent Transportation Systems, 2003:v. 2, p. 1060 (Ramp metering is the application of control devices such as metering signals to regulate the number of vehicles entering the freeway in order to achieve some operational objective. Ramp metering can keep mainline volumes below capacity by controlling the number of vehicle entering the freeway)

found: KSCE journal of civil engineering, May 2004:p. 335 (Simulation-based evaluation for urban expressway ramp metering ... Ramp meters are traffic signals that control traffic at entrances to freeways and address two primary objectives. The first is to control the number of vehicles that are allowed to enter the freeway; and the second is to break up the platoons of vehicles released from an upstream traffic signal)
