摘　　要：以陕西省西宝高速公路为依托,设定高速公路运行状况的安全性评价指标以及效率性评价指标。采用VISSIM仿真的方法获取各项指标的仿真数值,通过对混行和分车道限速两种情形下仿真数值结果的比对分析确定不同限速方案下的指标变化情况,进而分析得出分车道限速方法的适应性。Relying on Xibao Expressway in Shanxi province, safety evaluation indexes and efficiency evaluation indexes of expressway operation status are set up,and the VISSIM simulation method is adopted,so as to obtain the simulation values of various indexes. Through the comparative analysis on simulation value results under two kinds of conditions like mixed flow and divided lane speed- limiting,the conditions of indexes changes under different speed- limiting schemes are determined,so as to analyze and obtain the adaptability of divided lane speed- limiting method.
