Baggage transfer is a critical factor in determining connecting schedules at hub airports. This paper examines the potential benefits of "ramp transfers"-bags that bypass the hub sorting facility because they have been presorted at their point of origin. It presents three idealized baggage...

Real data show that reserving a lane for carpools on congested freeways induces a smoothing effect that is characterized by significantly higher bottleneck discharge flows (capacities) in adjacent lanes. The effect is reproducible across days and freeway sites: it was observed, without...

This paper describes a freeway incident detection scheme that does not rely on complicated theories. The procedure compares the occupancy information recorded by two neighboring loop detectors to determine whether an incident has occurred in the intervening segment, using a recipe that is...
