主线机动容量合理分配的匝道协同控制
Reasonable allocation of flexible capacity for ramp coordinated metering
摘要
Abstract
The idea of flexible capacity and the problem of its reasonable allocation for ramp coordinated metering are put forth in consideration of the traffic characteristics of periphery road. The optimal coordinated control mete-ring of multi-ramps is discussed , and the efficiency and equity of flexible capacity allocation is analyzed by modif-ying the length of control cycle. A modified ramp latency model is posed using the method of queuing theory, and the related redundancy latency cycle amount is designed to evaluate the consequence quantitatively. With in-situ traffic flow data, two scenarios of no-control and coordinated with different flexible capacity using strategies are compared. Results demonstrate the advantages of the new method.关键词
