For the 3D visualization progress of highway projects, considering that the roadbeds are always numerous in quantity and different in sizes, the traditional 3D modeling method of roadbed always costs a lot of manpower and time. Thus, this paper investigates the 3D parametric modeling method of roadbed based on Cesium. Based on the analysis of parametric modeling method using Cesium, the secondary development is carried out on the Cesium API to realize the rapid generation of roadbed cross section and center line of highway in the software by using Polyline Volume Function, which contributes to the realization of rapid 3D modeling of roadbeds. For the convenience of the inspection and modification of the design scheme for roadbed cross section, the JavaScript code is applied to create the interface of parameter design of the standard roadbed cross section. Then the standard roadbed cross section can be created by directly inputting parameters, which realized the rapid model generation of standard roadbed cross section. The research results are able to provide decision-making basis for traffic planning departments in highway route selection and in other aspects.
