IEEE Transactions on Intelligent Transportation Systems, (IEEE TITS), 2025.

• proposed a mixed traffic flow control structure, utilizing multi-lane fleets composed of a small portion of CAVs in mixed flow as mobile actuators. Multiple fleets formed within the mixed traffic flow feature a novel structure and a valve-like function that regulates both traffic volume and speed, referred to as “valve fleets”, which are applied to decongest freeway bottlenecks.

IEEE Transactions on Intelligent Transportation Systems, (IEEE TITS), 2024.

• Proposed a multi-lane platoon formation scheme that coordinates the lane-changing decisions and longitudinal trajectories of CAVs to form platoons based on each vehicle’s target lane, aiming to reduce the negative impact of lane-changing maneuvers on traffic flow and improve platoon formation efficiency. The platoon configurations and vehicles’ motions are jointly optimizaed dynamically to enhance flexibility.

• Proposed a trajectory optimization method for platoon formation that assigns and regulates vehicles distributed across different lanes into platoons with undefined vehicular sequences, aiming to reduce vehicle delays and time consumption.
