Abstract: A recently proposed paradigm for vehicular traffic in the era of CAV(connected and automated vehicles), called TrafficFluid, involves lane-freevehicle movement. Lane-free traffic implies that incremental road widening(narrowing) leads to corresponding incremental increase (decrease) of capacity;and this opens the way for consideration of real-time internal boundary controlon highways and arterials, in order to flexibly share the total (bothdirections) road width and capacity among the two directions in dependence ofthe bi-directional demand and traffic conditions, so as to maximize the total(two directions) flow efficiency. The problem is formulated as a convex QP(Quadratic Programming) problem that may be solved efficiently, andrepresentative case studies shed light on and demonstrate the features,capabilities and potential of the novel control action.
