Based on the shortest path matrix of 20 cities, we have quantitatively evaluated the highway network development level of the region by the accessibility index, extension index, conglomeration index, and etc. The result shows that in the space structure the highway network development level is a "core-margin" model. The cities with higher accessibility indexes gather around Zhengzhou City, while those with lower ones distribute in the margin. The order among conglomeration index is accordant to that of accessibility index.
