AbstractThe external space is an important factor contributing to city construction. he openness is often used to measure the external spaces. The original openness models have some limitations such as that the view angles are confined to upward angles or the space under the viewpoint is ignored. This paper developed a new model based on the original 3D-openness model and index set of comprehensive quantification is established. The 3D-openness of main road is also extracted and analyzed. A typical block of 3D-openness parameters are discussed in different ways. The new model could be used in urban landscape design and city planning.
