On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

A series of spatial syntactic variables is discussed in the paper. Taking Wuhan's traffic axial map as a case, spatial syntactic variables of multi-scale spatial extent based on GIS are analyzed. A conclusion is that the accessibility is the key factor that weighs an urban spatial morphology, and the integration degree is a direct variable describing accessibility.

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.

Taking the active network as a research task, the input accessibility, the Coates graph of matrix and graph transmission etc are used to analyze the relation between reducibility of the coefficient matrix of the state equation and the electric separability of the network or the electric accessibility of the network for the first time, acquiring sufficient and necessary conditions that coefficient matrix of the state equation is reducible. Network Graph Theory, Matrix Theory and System Theory over F etc are used to derive the structural controllability criterion of the passive network over F for the first time. Then according to these theoretic results, the structural controllability problems of the active network over F are studied, acquiring several structural controllability conclusions of the active network.

The case of a bus route in Qinghuangdao was studied. The analysis results show that the efficient way to improve bus accessibility is to keep bus headway not more than 5 min, so that the optimum bus-stop spacing is below 600 m no matter how much the bus passenger demand is. But on condition of higher bus headways, optimum bus-stop spacing should be in the range of 900 to 1400 m and the bus accessibility would drop more remarkably compared with lower bus headways.
