Massachusetts is investing $75 million in thermal-camera technology designed to detect wrong-way drivers before they cause catastrophic crashes. This episode of TechMobility Topics examines how these intelligent roadway systems work, why early detection can save lives, and what it takes to integrate real-time monitoring with transportation infrastructure. More importantly, we tackle the broader policy question: why do major roadway safety improvements so often come only after fatal crashes? We explore whether proactive investment, rather than reactive spending, could prevent the next tragedy instead of simply responding to it afterward.
