高等级公路匝道调节器设置的数学模型

Mathematical Model of Layout of High Grade Highway Ramp Metering System

本文探讨高等级公路匝道调节器设置对匝道转线车流运行模式的影响。从研究交汇运行特性入手，获取交汇断面边界流量；依据排队和合流理论，分析控制方式与合流运行的相互关系；利用网络和随机服务理论得到匝道调节器设置的数学模型。

This paper inquires into the influence of the layout of high grade highway ’sramp metering system on the operation mode of ramp turning traffic flow. From the study ofmerging operation characteristics,the boundary traffic of the merging section is obtained. Then based-on the queueing theory and merging theory,the rglation between control modeand merging operation is analysed.Mathematical model of the layout of ramp metering sys-tem is obtained by utilizing network and random service theory.
