Based on the hierarchical characteristics of passengers transfer behavior and the statedependent queuing model, the D-M/G/C/C queuing network simulation model was put forward for simulating the coordination of subjective passenger behavior and objective distribution environment. Then, the generation method and algorithm of the model is elaborated. In case study, the simulation results are consi...

OBJECTIVES To describe the trip characteristics of vehicle crashes involving children, and to examine the effect of situational factors on front row seating or inappropriate restraint for young children. METHODS A cross sectional study was conducted on children <16 years in crashes of insured vehicles in 15 US states, with data collected using insurance claims records and a telephone intervie...

In this paper, we capture the moderating effect of aggressive driving behavior while assessing the influence of a comprehensive set of variables on injury severity. In doing so, we are able to account for the indirect effects of variables on injury severity through their influence on aggressive driving behavior, as well as the direct effect of variables on injury severity. The methodology used ...

Air transport system has always been involved in all aspects of life because of its high potential in transporting passengers and goods. In this research we surveys the effects of travel variables on demand of domestic air transport, and for gathering required information from passengers, a questionnaire was designed including 20 effective parameters on air transport demand with questions These...

Demand-responsive transport systems use shuttles to provide door-to-door shared-rides for its passengers. The operating cost of the shuttles depends on the pick-up and drop-off locations of the passengers. It is challenging to design a fair cost-sharing mechanism that offers fare quotes to potential passengers without having any knowledge of future ride requests since different passengers cause...

Public transport information systems have been shown to positively affect passengers’ usage of their city’s transport infrastructure, by providing information such as the location and schedules of trains and buses. These systems, however, lack qualitative information about passengers’ ongoing experiences and may be out of date. In this work, we examine how smartphones can be leveraged to provid...

1. Let us agree on the following notation. Lower-case Latin letters from a to n (inclusively) with indices and without them will be used as variables for nonnegative integers, the remaining lower-case Latin letters will be used as variables for integers. Analogously, lower case Greek letters from to will be used as metavariables for nonnegative integers, and the rest of the Greek letters will b...

fischer-tropsch synthesis is a promising route for production of light olefins via co hydrogenation over transition metals. co is one of the most active metals for fischer-tropsch synthesis. some different variables such as preparation parameters and operational factors can strongly affect the selectivity of fischer-tropsch synthesis toward the special products. in the case of preparation varia...

Genomic instability causes cancers to acquire hundreds to thousands of mutations and chromosomal alterations during their somatic evolution. Most of these mutations and alterations are termed passengers because they do not confer cancer phenotypes. Evolutionary simulations and cancer geno...
