This report documents the findings of research sponsored by the Los Angeles World Airports to examine the influence of airport capacity constraints on airline fleet mix and to explore the potential effects of policy options to influence airlines to use larger aircraft types and thereby...

Inspecting and monitoring oil-gas pipelines, roads, bridges, canals are very important in ensuring the reliability and life expectancy of these civil systems. An autonomous Unmanned Aerial Vehicle (UAV) can decrease the operational costs, expedite the monitoring process and be used in situations...

This is the final report for the project entitled "Evaluation of the Effects of Intelligent Cruise Control Vehicles in Mixed Traffic". The project was initially under MOU392 and switched to Task Order 4217 at the beginning of the 2nd year of the project. Due to this administrative change a final...

This paper proposes a macroscopic behavioral theory of traffic dynamics for homogeneous, multi-lane freeways. The theory makes predictions for separate groups of lanes while recognizing that the traffic stream is usually composed of aggressive and timid drivers. Its principles are so simple that...

This report presents the results of its assessment of transit service integration practices in the United States. Initially, a review of the literature was performed that identified the various types of service integration policies that have been and are being implemented including...

There have been significant improvements in recent years in transportation and emissions modeling, in order to better evaluate transportation operational effects and associated vehicle emissions. In particular, instantaneous or modal emissions models have been developed for a variety of...

This report presents and describes the expanded database containing 873 aviation accidents which occurred within five miles of an airport. Section 2 contains a description of the development of the database and a discussion of the criteria used in selecting accidents for the database. Section 3...

We comparatively assess the influence of adaptive cruise control (ACC) and cooperative adaptive cruise control (CACC) systems on highway traffic behaviors. The primary goal is to study the design and implementation of vehicle-vehicle/roadside-vehicle communication, which enhances an ACC system...

In this report the authors present a unified framework for carrying out safety calculations for the automated highway problem and obtain sufficient conditions for a set of continuous controllers to be safe and use these conditions to design a discrete scheme that switches between them....
