Changes to the National Airspace System will occur as part of the Next Generation Air Transport System. The consequences of these changes on the situation awareness of pilots and air traffic controllers need to be identified. Before situation awareness metrics can be deployed towards this goal, metrics that can unambiguously capture baseline levels of situation awareness in the current day Nati...

This paper presents the validation method and its evaluation of the spontaneous braking and lane changing with scope awareness parameter. By using the real traffic flow data, the traffic cellular automaton model that accommodate these two driver behaviors, e.g., spontaneous braking and driver scope awareness has been compared and evaluated. The real traffic flow data have been observed via vide...

In general, traffic service quality can be described by different parameters and the traffic level of service (LOS) is mainly determined by one of them, such as traffic flow or traffic speed. However, the traffic phenomenon is extremely complex; its characteristics cannot be well represented only by one single parameter. The aim of this research is to determine a more representable LOS based on...

Following some former epidemiological studies led in the general population, consumption of psycho active medicinal drugs concerned 18% o f adults, females for the most part o f them (70% ), with a high relative age (55,5 years); 45% o f them had used those drugs during the year before the study and 25% used them since more than 10 years ( Haeusler 1988). In teenagers, 8% were multiple users an...

According to the characteristics of airport pavement traffic, we discuss a method of building an airport pavement traffic model which is based on CPN theory and simulate a practical situation as well. The method overcomes the shortage of modelling with normal Petri Net theory, solves the difficult problems of airport pavement traffic such as complex traffic nets, frequent road changing, etc., r...
