Data collected on Uber drivers’ smartphones could help monitor bridges and stop them from collapsing, a new study suggests. Collecting drivers’ GPS location and acceleration data – both automatically recorded by ridesharing apps like Uber – give structural engineers key insights into a bridge’s health, according to the research. It would provide them with almost constant real-time monitoring of a bridge’s robustness and potentially reduce the number of deadly collapses. Sky News
