The real-time vehicle routing problem with time windows and simultaneous delivery/pickup demands (RT-VRPTWDP) is formulated as a mixed integer programming model which is repeatedly solved in the rolling time horizon. The real-time delivery/pickup demands are served by capacitated vehicles with limited initial loads. Moreover, pickup services aren’t(More)
This paper presents a stochastic optimal-control-based approach to real-time incident-responsive coordinated ramp control. The proposed coordinated ramp-control methodology includes two major functions, i.e., 1) identification of control-zone-based congestion patterns using the modified generalized-sequential-probability-ratio-testing technology and 2)(More)
