Abstract: With the development of active safety technology and autonomous driving technology, high precision map has been used in many applications. A road geometry analytical model based on mileage parameter was proposed for high precision map. By constructing the orthogonal polynomials based on the data set and using restricted least-square method, the geometric description parameters were dynamically calculated based on maximum fitting error. The model can precisely describe the road geometry, and minimize the data redundancy. It can also ensure the continuity and smoothness of the road geometry. The model was used for high precision map production of 120 km highway. Taking three typical roads as examples, the advantages of proposed model were validated.

Key words: road geometry, analytical model, high precision map, orthogonal polynomials, restricted least-square method
