Proactive AI for Intelligent Traffic Control

ProLight develops next-generation intelligent transportation systems that anticipate disruptions, predict network dynamics, and optimize urban mobility through advanced simulation, graph learning, predictive planning, and autonomous decision-making.

From reactive traffic control to
proactive network intelligence

Urban traffic networks are complex, uncertain, and vulnerable to disruptions. ProLight investigates how AI systems can predict future traffic states, reason over network-level interactions, and make robust control decisions before congestion propagates.
