Abstract:
A simple highway segment followed by a bottleneck is considered, subject to a wave or pulse of traffic demand, having restricted duration and a maximum which is higher than the capacity of the bottleneck. The proposed control of the flux is to impose a reduction of the maximum speed allowed in the segment, based on the measured arrival rate of vehicles (feedforward). The performance criterion is the weighted sum of the average traffic time with the average " stop and go " or queue time. The search for the optimal control rule is done through simulation with the software Arena; statistical distributions are " triangular ".
