This report constitutes the final report for Calendar Year 2001 (CY01) under Contract Number NAS2-99072 for the third year of a three-year research project entitled “Development of Fast-Time Simulation Techniques to Model Safety Issues in the National Airspace System.” The objective of this research is to investigate and develop techniques to enable NAS fast-time simulation modeling to be useful for conducting safety analysis. The research efforts focus on examining the type of safety issues that could be appropriately modeled by fast-time simulations and developing, testing, and...

In this article we use four different indices to measure cost performance of the European Airline Industry. By using the number of routes as an indicator of Network Size, we are able to estimate indicators of Economies of Density, Network Size and Spatial Scope. By estimating total and variable cost functions we are also able to calculate an index of the excess capacity of the firms. For this purpose, we use data from the years 1984 to 1998, a period during which several deregulation measures were imposed on the European airline industry. Some of the implications of this deregulation...

Over the past several years, Urban Air Mobility (UAM) has galvanized enthusiasm from investors and researchers, marrying expertise in aircraft design, transportation, logistics, artificial intelligence, battery chemistry, and broader policymaking. However, two significant questions remain unexplored: (1) What is the value of UAM in a region’s transportation network?, and (2) How can UAM be effectively deployed to realize and maximize this value to all stakeholders, including riders and local economies? To adequately understand the value proposition of UAM for metropolitan areas, we develop...

At a national level it is common to express the amount of air travel in terms of the number of revenue passenger miles flown or the number of enplaned passengers. This provides a way to resolve the difficulty of how to aggregate measures of air travel in many different markets of many different distances. However, information about the distribution of trip lengths is lost in the process. This information is of interest for a number of reasons. The type of aircraft that is most appropriate for different markets depends on the distances involved. The length of the trip is also likely to...
