A novel speed model for safety evaluation of freeway alignment in Euclidean 3D space.

CONCLUSIONS: It can be concluded that there is a clear correlation between velocity and spatial curvature, which is proved by variance analysis. The estimation results of the speed models are reliable as tested using a real engineering example. The study would provide a scientific basis for safety evaluation of freeway alignment.
