Distributed autonomous intersection management with neuro-evolution
… Neuro-Evolution specifically to the field of intersection management, in order to study which methods are the most effective for this particular task. In particular we investigate three key hyper-parameters: Neuro-Evolution algorithm, task difficulty and problem exposure. A traffic simulator …

A delayed response policy for autonomous intersection management
… drivers, not autonomous vehicles. The Autonomous Intersection Management (AIM) project at UT Austin aims to propose a large-scale, real-time framework to be a substitute for current traffic light and stop signs. Automobiles in modern urban settings spend a lot of time idling at intersections. In …

A hybrid approach for intersection management in V2X-enabled connected vehicles
… in accurately perceiving and navigating through intersections mainly due to occlusions. This thesis addresses these challenges by integrating Vehicle-to-Everything (V2X) communication with onboard sensors to improve AV perception and decision-making capabilities. In particular, this thesis …

Fuzzy logic-based intersection management for delay minimization in intelligent transportation systems using V2X communication
… thesis proposed a fuzzy logic-based approach for intersection management using V2X communication and synchronization with regular traffic light systems to minimize vehicular traffic delays. The fuzzy logic model accepts queue length, waiting time, speed, and distance as input and output phase …

ENHANCING TRAFFIC FLOW USING VEHICLE DASHBOARD TRAFFIC LIGHTS WITH V2I NETWORKS
… flow on the streets, especially in regards to intersection management. Research studies have been conducted to replace the Pre-timed traffic lights at the intersections with adaptive traffic lights control systems that base their timings on the traffic flow. Other studies have suggested the use …

Planning for autonomous vehicles : ridesharing and traffic control
… vehicle routing (SAV) problem and the autonomous intersection management system (AIM) location problem. The SAV routing problem is finding the optimal SAV to passenger matching as well as the SAV route choice. Since widespread use of SAVs would have significant effects on traffic congestion, we …

A Real-Time Server Based Approach for Safe and Timely Intersection Crossings
… This manuscript focuses on traffic control at intersections, since urban roads with closely spaced intersections are often prone to queue spillbacks, which disrupt traffic flows across the entire network and increase congestion. While various intelligent traffic control solutions exist for …

Safe and Efficient Intelligent Intersection Control of Autonomous Vehicles
… we address a problem of safe and efficient intersection crossing traffic management of autonomous and connected ground traffic. Toward this objective, we propose several algorithms to handle different traffic environments. First, an algorithm that is called the Discrete-time occupancies …
