  During the last decade, road network vulnerability assessment has received an
increasing attention. On one hand, it is due to the significant advances in
Network Science and the potentialities that its tools offer. On the other hand,
it is due to its utility for urban planning and emergency response. Despite
these facts and the increasingly available data, related work is still sparse
in Latin America, even more so in Ecuador. Due to its geographical, historical,
and social characteristics, the city of Quito is considered as a case study. At
first, the spatial distributions of several topological centrality measures are
analyzed. As expected, there are hotspots where high values of these measures
concentrate. These results serve to further simulate several strategies for
disconnecting the urban road network. Finally, we observe that centrality-based
strategies are more effective than randomly-based strategies in disconnecting
the network.
