Latest Patents

Xie’s latest patents include innovative methods and systems for adaptive traffic signal control. His scalable urban traffic control system offers a new approach to real-time management of traffic signal networks. The methods described exploit a novel conceptualization of the signal network control problem as a decentralized process. Each intersection in the network independently and asynchronously solves a single-machine scheduling problem in a rolling horizon fashion to allocate green time to local traffic. Intersections communicate planned outflows to their downstream neighbors, increasing visibility of future incoming traffic and achieving coordinated behavior. This novel formulation abstracts vehicle flows into clusters, enabling orders-of-magnitude speedup over previous time-based formulations. This allows for truly real-time (second-by-second) responses to changing conditions.
