针对高速公路客车货车混行相互干扰造成交通效率下降的现象，基于客货分道划分方法，提出高速公 路客货分道动态控制的理念。以美国加利福尼亚州i5高速公路为例，运用vissim软件建立模型，对单向三车道、 四车道和五车道在不同的交通流量和不同的客货比下进行仿真，分析对客货分道控制的效果，绘制客货分道动 态控制系统流程图。研究结果表明：客货分道在一定的条件下能够有效降低车辆的平均延误，提高车辆的平均 速度；客货分道动态控制系统的有效适用范围，单向四车道客车与货车的标准量比值为1/8～20；单向单车道客 车与货车的标准量比值为1/4～20；单向五车道客车与货车的标准量比值为1/12～10。
Aiming at the phenomenon that the mutual interference of mixed traffic of passenger car and truck on expressway，causing the decline of traffic efficiency，the concept of dynamic control of passenger-cargo division lane in highway was proposed based on the passenger and freight lane division method. Taking the i5 expressway in California as an example，the model was established using the vissim software. Three，four and five lanes with different passenger-cargo ratio were simulated under different traffic flow. The control effect of passenger-cargo lane separation was analyzed. And the flow chart of lane separation dynamic control system was drawn. The research results show that the separation of passenger-cargo lane can effectively reduce the average delay of vehicles，and improve the average speed of vehicles. The effective application range of dynamic control system of passenger-cargo separation can be described as，the standard quantity ratio of passenger car to truck for one-way four lane is 1/8～20，the value for three lane is 1/4～20，the value for five lane is 1/12～10.
