Whenever a long queue is detected at the metered ramp, the signaltiming should be adjusted to reduce the traffic flows entering the ramp. 當管匝道上排隊較長(cháng)時(shí)，系統將通過(guò)自動(dòng)調整來(lái)減少進(jìn)入匝道的車(chē)流量，以保證匝道控制系統的有效性，避免匝道排隊過(guò)長(cháng)，減少高速公路癱瘓的可能性。
The decomposition and coordination methods applied to large system design are used for coordinated ramp metering on freeways. 摘要采用大系統分解和協(xié)調的方法研究高速公路多匝道的協(xié)調控制問(wèn)題。
