摘　　要：阐述互通匝道中超高取值的问题,根据匝道功能,确定汽车在匝道上实际运行车速。根据实际运行车速来确定匝道超高值,达到匝道安全、舒适行车的要求。Superelevation valuating of interchange lamps is introduced in this paper. According to functions of ramps, the actual driving speed of vehicles in ramps is determined, and superelevation of ramps is determined based on actual driving speed, so to meet with the requests for safe and comfortable driving in ramps.

关 键 词：互通 匝道 超高 实际运行车速
