Prof. Claudio Roncoli, (Aalto University, Finland), will deliver a talk entitled 'Integrated control of motorway bottlenecks via flow metering and lane assignment', at  the Technical University of Crete on September 10, 2018.

Abstract: 
Lane-changing control is a promising feature that can be exploited for traffic management at bottleneck locations (e.g., lane-drops, on-ramp merges), where human drivers usually perform suboptimal lane-changes based on erroneous perceptions, which may trigger congestion. In the presence of a sufficient percentage of vehicles equipped with lane-changing automatic controllers or advisory systems, the overall throughput at the bottleneck location may be improved by execution of specific lane-changing commands dictated by a central decision maker.

We address in this talk the problem of maximising the outflow at motorway bottlenecks via a combined exploitation of flow metering and lane-changing control, by proposing a novel integrated approach that allows to jointly exploit mainstream (or ramp) flow metering together with lane-changing control, while accounting for unmeasured demand flows and incomplete measurements. The proposed control strategy aims at regulating the mainstream flow, actuated, for example, via ramp metering or variable speed limits, and the lane assignment of vehicles upstream of a bottleneck location in order to maximise the bottleneck throughput. Moreover, the proposed strategy is capable of handling efficiently the case of mixed traffic, where manual vehicles may not receive or may not follow the prescribed lane-changing commands.
