Automated vehicles have the potential to revolutionize our nation's transportation systems as they promise to dramatically reduce congestion, accidents, and fuel usage. Namely, as it becomes possible to precisely exert control on and coordinate the movement and placement of vehicles along a stretch of highway, the separation distance between vehicles can be reduced, thus increasing flow and minimizing congestion. Precise and coordinated vehicle controls and placements also improve predictability, resulting in fewer instances of sudden braking, which reduce fuel usage and accidents. Most existing research has focused on the steady-state behaviors and operations of automated vehicles, such as platooning, and assumes complete knowledge of the system, e.g., the number of vehicles and their destinations and/or neglects dynamic or transition operations such as exiting a highway and lane changing. Uncoordinated lane-changing and exiting behaviors by automated vehicles can significantly reduce the flow of traffic as vehicles will require larger separations, are forced to slow down, or worse, collide. In this paper, we present a collision-free runtime approach to efficiently organize the departures of automated vehicles from a highway environment while maintaining highway capacity in extremely dynamic conditions. To maximize the number of safe departures, the key ideas are to: 1) determine when, and where to, an exiting vehicle should lane change in order to make a successful exit given current traffic conditions as provided by connected vehicle technology and 2) execute the actual lane-change operations using a reservation-based approach. Simulation results show that, by coordinating vehicles' behaviors, traffic flow can be improved by up to five times of today's typical flow while ensuring a 100% exit success rate in a collision-free manner.

Abstract-This paper presents an approach to lane assignment for highway vehicles that increases traffic throughput while ensuring they exit successfully at their destinations. Most of current traffic management systems do not consider lane organization of vehicles and only regulate traffic flows by controlling traffic signals or ramp meters. However, traffic throughput and efficient use of highways can be increased by coordinating driver behaviors intelligently. The goal of this research is to form a distributed control strategy for cars themselves to select lanes using inter-vehicle communication.Initial results are promising and demonstrate that intelligent lane selection can decrease vehicle traffic time.

“…A static lane assignment problem ([l], [Z], [3], [4]) has been studied to grasp the essential features of lane scheduling under simplifying assumptions that decouple the system wide traffic flow problem from the dynamic effects of the motion of individual vehicles. These assumptions include coarse time discretization of the daily operating cycle (and neglect of coupling of flows between different time instants), fixed capacities of lanes and sections of the AHS, approximate (implicit) representation of maneuvering delays in determining the optimal and suboptimal lane assignments and non-consideration of the actual control and communication strategies used.…”

Recent activities in advancing surface transportation systems have focused on the development of IVHS (Intelligent Vehicle Highway Systems) and in particular AHS (Automated Highway Systems). They aim to enhance system operation and maintenance in order to reduce congestion, enhance safety, reduce travel time, improve trip quality and produce beneficial effects on the environment. Another important component of the overall program in advancing surface transportation is the Corridor project. In this paper, we propose an algorithm for route guidance combined with lane assignment, on urban highways in Corridor systems as a means of traffic control that can be integrated with overall plans for controlling traffic in such systems. The proposed algorithm makes use of a simulator that is capable of micro-modeling traffic on semi or fully automated highways.
