The metropolitan area of Lima and Callao located on the central coast of Peru, experiences high seismicity. However, the effects on critical infrastructure, particularly the urban road network, have been insufficiently studied. This study aims to evaluate two indexes using a matrix database, organized into four categories with 17 evaluation parameters, within a representative study area that includes all soil types defined by Peruvian regulations. First, data were collected to parameterize the main factors for determining seismic vulnerability indexes, which identify the most vulnerable sectors or roads. A second index of operational functionality assesses the road’s importance and its performance during peak and off-peak hours to identify which roads would remain operational in disaster. This selection prioritizes roads with greater capacity to connect main facilities, support urban logistics and facilitate passenger transport, particularly in areas with major mass transportation systems and the national highway that transports goods to the north, center, and south of the country.
