基于ALINEA算法的上海快速路入口匝道控制方法

ALINEA Algorithmbased Onramp Control for Expressways in Shanghai

摘要:

通过分析上海典型匝道——内环内侧武夷路上匝道，将国外运用较为成功的单点控制方法——ALINEA算法，在附加考虑匝道排队长度限制的基础上，运用于实际的工程实践.经过离线模拟，发现主线速度得以提高,同时匝道流量的脉冲性被一定程度地平滑了.故认为:以ALINEA算法为基础的控制方法,适用于上海快速路入口匝道控制.

Abstract:

ALINEA algorithm is adopted to solve the congestion of the merging area of Wuyi onramp with a consideration of the restriction of the queue length by analyzing the the geometric layout and traffic data of the Wuyi onramp.Results show that the speed of the mainline has enhanced and the pulse characteristics of ramp volumes has weakened by offline simulation. So ALINEA algorithm is deemed to be a suitable method for onramp control of Shanghai expressway.
