The practice of implementing urban plans for the construction area City Belgrade has shown that in some cases they do not contain enough elements to implement directly. This is especially true special purpose sites and facilities, whose design require pre-definition more detailed conditions rules landscaping construction. In order address such issues, authors explore developing analyses case ai...

This paper presents a novel approach to managing the aircraft taxi-out process at airports, by posing the problem in a network congestion control framework. A network model of the airport surface with stochastic link travel times is first developed. The model parameters for Boston Logan International Airport are estimated using empirical data from a surface surveillance system. Using the entry ...

A runway incursion is a situation where two or more aircraft or vehicles occupy one runway simultaneously and as such create a potentially dangerous situation. We can think of many situations where two aircraft/vehicles occupy the same runway simultaneously, but do not cause a conflicting situation, e.g. two taxiing aircraft on a closed runway or a departing aircraft lining up behind a landing ...

The increasing complexity of Air Traffic System is pushing toward the development of innovative and more automated tools conceived to manage it. In this scenario an important role is assumed by HCI (Human Computer Interfaces) used by air traffic controllers and operators to visualize and interact with air traffic data. Currently, information about 3D scenery are displayed with a two-dimensional...

Airport traffic consists of aircraft performing landing, takeoff and taxi procedures. It is controlled by air traffic controller (ATC). To safely perform this task he/she uses traffic surveillance equipment and voice communication systems to issue control clearances. One of the most important indicators of this process efficiency is practical airport capacity, which refers to the number of airc...

• Runway incursions and conflicts present a persistent problem in airport ground operations. Numerous critical conflicts and several fatal accidents have occurred as a result of unauthorized or otherwise inappropriate entry of aircraft or surface vehicles onto an active runway. This article describes a detailed survey of runway-conflict accidents and high-hazard incidents res,ulting from inappr...

As demanded at Collective Employment Agreement (CEA), three ergonomic assessment of work (AEW) were made into an airport from a big Brazilian city (in particular, at the flight tower), with a 2 years interval between them. The objective was to produce a report pointing out problems and solutions. At the third time (2010), were verified that the work conditions where almost the same from 2006 an...

The oscillations of tall slender towers under environmental loads are usually of large amplitude. In order to protect these structures, suitable absorbers can be installed to control or limit the amplitude of oscillation. In this paper, passive and hybrid control strategies are used to improve the dynamic response of a tall tower. A pendulum attached to the top of the tower is used as a vibrati...

Today, tower cranes are in widespread use on construction sites all around the world. An important issue that arises when operating these cranes is the oscillatory behavior that occurs during payload transportation, which can have severe effects on safety as well as accuracy of payload delivery. Due to the nonlinear nature of the rotating crane motion, controlling these oscillations is a comple...
