Abstract & Overview
Superelevation design can basically be regarded as an important part of highway route design system. In the specific design process, designers need to strictly comply with the requirements of superelevation design specifications to ensure the driving stability of curved road section. However, due to the differences of road operation conditions in different regions of China, there are many uncertain factors in the design of super elevation, resulting in design errors. In order to reduce design errors as much as possible, this paper mainly based on the highway route design, highway route design problems and key measures are summarized for reference.
