| 摘要： | This paper presents the development of a centrally controlled segmented system wide adaptive ramp metering (SWARM) system. This adaptive ramp metering approach includes the use of two algorithms SWARM 1 and SWARM 2. The development of this system was initiated by the California Department of Transportation's (Caltrans) Freeway Traffic Management System in the Los Angeles area. One of the largest systems in the world, it encompasses over 30,000 traffic detectors and 1,200 ramp meters. Currently, ramp metering operations are based on time-of-day tables that are periodically updated and an automatic local mainline responsive algorithm. |
