摘　　要：阐述了高等级公路视距加宽计算方法在高等级公路设计中的应用。通过行驶速度建议值修正停车视距计算公式,对比计算横净距和公路既有横净距,确定公路视距加宽值,并提出具体解决措施。该方法适用于以小客车为主要车型的高等级公路平面视距加宽计算,可以提高公路设计工作效率,可以在一定程度上避免视距不足导致交通安全事故的发生。The application of sight distance widening calculation method in high-grade highway design is elaborated.The calculation formula of stopping sight distance is modified through the recommended value of driving speed,the calculated transverse clear distance is compared with the existing one of the highway,the widening value of highway sight distance is determined,and the specific solutions are put forward.This method is applicable to the widening calculation of plane sight distance of high-grade highway with passenger cars as the main vehicle type,which can improve the work efficiency of highway design and avoid traffic safety accidents caused by insufficient sight distance to a certain extent.
