“…19 A study in Brazil that examined utility wires indicated they may also present the risk of electrocution/electrical fire. 51 Studies show an association between visible utility wires and negative health outcomes. 19 Computer vision models were unable to accurately identify other indicators of physical disorder, including litter (too small to be seen), graffiti (rare outside of some urban settings), and poor building condition (large variation in appearance).…”

“…From images, we also extracted the presence of visible wires. The literature on visible wires is nascent and more of this work has been done abroad, for instance in Rio de Janeiro, where the wires represent both an unsightly presence and a possible electrocution/electrical fire risk [28]. In the United States, visible wires have mainly a visual impact on the landscape.…”

“…Visible utility wires hanging overhead are visually striking and may impact residents’ aesthetic sense of their environment, altering perceptions of safety or pleasurability and influencing both mental health (by affecting stress levels) and physical health (by disincentivizing walking). Other studies that have examined this indicator have been done outside the U.S., where they may also represent an unsightly presence and electrocution/electrical fire risk [ 27 ]. Computer vision models have struggled with small objects, precluding us from labeling other indicators of physical disorder such as litter or trash [ 19 ].…”
