By considering the length and "width" of the road in urban transportation systems, this paper empirically investigates the topological structure properties for three realistic urban road networks in the United States, where road segments and junctions are represented by links and nodes, respectively. Links and nodes are embedded in metric spaces and the small-world effect is discussed in regular networks with metric spaces. The "width" of a road can be alternatively described by its capacity. Distributions of degree, capacity and length for these three realistic urban road networks are mainly analyzed. Finally, load distribution in these urban road networks is also explored.
Keywords:Transportation Engineering; Urban road networks; Load distribution; Topological structure
