高等级公路可接受间隙控制系统分析与构模

Analysis and Forming-Model of Acceptable GapControl System (AGCS) on High-Class Highway

本文针对我国机动车辆构成的实际情况，简析高等级公路立交地段车流特性、可接受间隙控制系统组成和运作情况，并对系统进行了抽象简化，构造了控制系统分析模型。利用该模型，能够得出高等级公路上不同交通需求条件下控制系统的运行状况。模型适用性强，不但适用具有合流匝道的入口控制，而且能用于单入口匝道控制系统分析，文中提出的系统评价指标反映实际，给出的分析示例说明了系统的有效性、正确性和通用性。

To the actual condition of the vehicle composition in our country, thetraffic flow characteristics in interchange area, the composition andoperation of AGCS are synoptically analysed. Making AGCS simplified,ananalysis model is established. With the. model , the operation condition ofcontrol system with different traffic demands can be obtained. The modelis of common use. It can be used to entrance control of merging ramp andsystem analysis of simple entrance ramp. The appraisal indexes presentedare conformed to reality. The example given shows the effectiveness andcorrectness of the system,
