Content SummaryWe propose an optimal feedback control strategy for lane-changing control at bottleneck locations, assuming that a percentage of vehicles, equipped with vehicle automation and communication systems, are capable of receiving and executing specific lane-changing orders or recommendations. Based on a simplified multi-lane motorway traffic flow model, we formulate an optimal feedback control problem, cast as a linear quadratic regulator problem, aiming at maximising the throughput at bottleneck locations, via optimal lane assignment of vehicles upstream of the bottleneck. The feedback control decisions are based on appropriate choice of set-points for traffic densities and real-time measurements of the state of the system. We also present an extremum seeking algorithm to seek the optimal set-points using only the measurement of a cost that is representative of the achieved traffic conditions. The proposed strategy is tested on a nonlinear first-order macroscopic multilane traffic flow model, which accounts also for the capacity drop phenomenon.en
