%X 引入可变限速的思想，考虑影响施工区车速的因素如V/C、 大车率、 服从率等因素，提出基于交通流理论和交通冲突技术的施工区可变限速模型. 通过仿真进行了模型的标定，并基于算例得到施工区的限速值. 研究结果表明： 该模型能克服现有限速方法的不足.<br>The paper introduces the variable speed limit thought，considers the V/C，large vehicle mix rates，the compliance rates and other factors，puts forward the variable speed control model based on traffic conflict technique and the traffic flow theory of the work zone. The paper calibrates the model through the vissim simulation，and based on an example calculates the value of speed limits. The result shows that the model can overcome the shortage of the current speed limits
