Abstract:
A method of an urban road network asset valuation includes: selecting a road network in an urban built-up region as a research object; segmenting each road in the network to different road sections; sequentially calculating the own asset, the epitaxial asset and the utility asset of each road section, the epitaxial asset being a change of an asset of the road section caused by buildings around the road section, and the utility asset being influence of a road section topological structure on the asset of the road section; accumulating the own, epitaxial, and utility assets of the road section to obtain the asset of the road section; accumulating the asset of each road section in one road to obtain the corresponding road asset; and accumulating the asset of each road in the network to obtain the valuated asset of the urban road network in the selected region.

Claim (Index 6):
The method according to  claim 5 , wherein in the step of calculating the utility asset of the road section k, firstly, two parameters, Edge Betweenness and traffic volume are defined, the Edge Betweenness means a proportion of the number of paths passing through the edge in the total number of all shortest paths on a road network, and the traffic volume means the number of passing vehicles in a unit time;\n next, assuming that \u03c3 ab =the number of shortest paths between the node a and the node b, \u03c3 ab k =the numbers of shortest paths between the node a and the node b passing through the road section k, the Edge Betweenness B k  is formulated as follows: B k = \u2211 a , b \u2208 N a \u2260 b \ue89e ( \u03c3 ab k \ue89e / \ue89e \u03c3 ab ) ; the length of the path between the node a and the node b is defined as the sum of impedance of all edges which the path includes, when sum of the impedance of all the edges which the path includes is minimum, the path is the shortest path between the node a and the node b, the impedance W k  of the road section k is defined as follows: W k = 1 F k , Where F k =service capacity value of the road section k; next the utility asset is valuated by two parameters, Edge Betweenness and traffic volume, the Edge Betweenness and the traffic volume are standardized and are changed into dimensionless quantities: \u03b2 k = B k - B min G B max G - B min G \u03b3 k = T k - T min G T max G - T min G Where B min G =minimum Edge Betweenness in the road network G; B max G =maximum Edge Betweenness in the road network G; T k =traffic volume of the road section k; T min G =minimum traffic volume in the road network G; and T max G =maximum traffic volume in the road network G; next, the weight \u03d5 is given to mean the influence of the Edge Betweenness on the utility asset of the road section, so that the weight by the traffic volume is (1\u2212\u03d5), subject to 0<\u03d5<1, the influence effectiveness of the topological structure on the asset of the road section is formulated as \u03c1 k =\u03d5*\u03b2 k +(1\u2212\u03d5)*\u03b3 k  and the utility asset S k  is defined as follows:\n S k =\u03c1 k *E k .
