Experimental studies of cognitively based air traffic control complexity metrics for future operational concepts
… need to be developed. This thesis developed the structure for a cognitively based complexity metric, Modified Aircraft Count (MAC). Cognitive complexity is decomposed based on in- individual aircraft complexity factors and sector level complexity factors. The complexity con- contributing of each …

Estimating the impacts of route changes for Chicago's rapid transit system
… significantly in recent decades but the current route structure is not optimized for current demand, leading to portions of the system which are underutilized and others which are overburdened and congested. As ridership has grown, congestion has increased on certain portions of the system, …

EXPLORING TRANSFORMATION OF STREET LAYOUT IN THE OLD CITY OF BEIJING: CASE STUDIES OF QIANMEN AND XISI
… The study seeks to understand the spatial structure and character of a metropolitan area by examining the patterns of its component parts and the process of its evolution. In particular, street pattern and route structure are the focuses rather than entire urban form subject. After the …

Composite variable formulations for express shipment service network design
… We focus on simultaneously determining the route structure, the assignment of fleet types to routes, and the flow of packages on aircraft. Traditional formulations for network design involve modeling both flow decisions and design decisions explicitly. The bounds provided by their linear …

Increasing Flexibility in the Design and Operation of Instrument Flight Procedures
… characteristics of airspaces by defining their route structure. The design of procedures is limited by a variety of constraints that restrict achievable aircraft trajectories. Many constraints originate from safety considerations and can interact in complex ways to limit flight procedure …
