分析了提高高速公路收费站通行能力的有效方法，对高速公路车辆在进入收费站前采取强制的客货车分流，并研究减速设施的合理前置距离．通过在强制分流点前合理位置设置道路指示标志，采用安全的强制减速设施控制车速后，选用限高措施对小型车和货车进行强制分流以提高收费站通行能力．应用VISSIM软件对实行强制分流后收费站通行能力与采用分流设施前收费站通行能力进行比较，验证了分流设施的有效性．

英文摘要：

The paper analyzes the effective methods to increase the capacity of highway toil gate. Man-datory van shunt measures are taken to the vehicles before entering the toll gate. The proposing direc-tion of deceleration facility is researched. Reasonable road directional signs are set in front of the forced diversion point and safe forced deceleration facilities are set to control the speed. Then the heigb~t limit installation is selected to diverse small cars and big trucks to increase the capacity of toll gate. Finally, the capacity of toll gate before and after adopting compulsory diversion facility is com-pared with application of VISSIM software. The effectiveness of the diversion facilities is testified.
