Designing effective aviation security systems has become a problem of national concern. Passenger screening is an important component of aviation security. Developing real-time passenger screening strategies can be quite challenging. This paper identifies a methodology that can be used in real-time to optimally assign passengers to aviation security resources for the Sequential Stochastic Multi...

The mechanisms for young drivers being at increased risk of collision with peer aged passengers in the car are not well understood. Most studies infer a link between passenger distraction and the number of passengers, but a causal link has not been previously shown. A group of young drivers with their full Ontario, Canada G license were tested in a simulated driving environment in three conditi...

Aimed at the complicated problems of attraction characteristics regarding passenger flow in urban rail transit network, the concept of the gravity field of passenger flow is proposed in this paper. We establish the computation methods of field strength and potential energy to reveal the potential attraction relationship among stations from the perspective of the collection and distribution of p...

The focus of recent research on disruption management in public transportation networks more and more shifts from operator-related aspects to improving the service quality. It is, however, not yet well understood how the passenger demand changes in a disrupted situation. Forecasts of passenger demand traditionally focus on the long-term. Forecasts for disruption management on the contrary requi...

Schedule disruptions require airlines to intervene through the process of recovery; this involves modifications to the planned schedule, aircraft routings, crew pairings and passenger itineraries. Passenger recovery is generally considered as the final stage in this process, and hence passengers experience unnecessarily large impacts resulting from flight delays and cancellations. Most recovery...

Air travel is becoming increasingly more accessible to people both through the availability of low cost flights. Health problems may arise due to anxiety and unfamiliarity with airport departure procedures prior to flying, whilst during the air travel, problems may arise as a result of the food served on board, differences in the environmental conditions inside the cabin, the risk of crossinfec...

Heavy-duty trucks make up only 3% of the on-road vehicle fleet, yet they account for > 7% of vehicle miles traveled in the United States. They also contribute a significant proportion of regulated ambient emissions. Heavy vehicles emit emissions at different rates than passenger vehicles. They may also behave differently on-road, yet may be treated similarly to passenger vehicles in emissions m...

Autotransporters are a superfamily of virulence factors produced by Gram-negative bacteria consisting of a large N-terminal extracellular domain ("passenger domain") and a C-terminal beta barrel domain ("beta domain"). The mechanism by which the passenger domain is translocated across the outer membrane (OM) is unknown. Here we show that the insertion of a small linker into the passenger domain...

OBJECTIVE To estimate the risk of serious nonfatal injuries in frontal crashes among belted children seated in the right front seat of vehicles in which second-generation passenger air bags deployed compared with that of belted children seated in the right front seat of vehicles in which first-generation passenger air bags deployed. DESIGN AND SETTING We enrolled a probability sample of 1781 ...

This paper continues our work on perturbation analysis of multimodal transportation networks (TNs) by means of a stochastic hybrid automaton (SHA) model. We focus here on the approximate computation, in particular on the major bottleneck consisting in the high dimensionality of systems of stochastic differential balance equations (SDEs) that define the continuous passenger-flow dynamics in the ...
