Traffic congestion is a global issue, which occurs during rush hour but also in situations of
emergency causing massive congestion. This paper proposes a method for building a
weighted road network by using the real-time traffic situation and the inherent characteristics
of Urban Road Networks (URNs). To research the cascading failure vulnerability of URNs
three kinds of node importance indexes are constructed from the structure, function, and
traffic flow characteristics. Then the feasibility and validity of the proposed model are verified …
