In this paper we investigate (in)security aspects of Automatic Dependent Surveillance-Broadcast (ADS-B) protocol. ADS-B is intended to be widely deployed in Air Traffic Management (ATM) Surveillance systems by 2020. One of the goals of ADS-B is to increase safety of air traffic. While the security of ADS-B was previously questioned, in this paper we demonstrate that attacks are both easy and pr...

INTRODUCTION Air pollution is an important problem for São Paulo city and vehicles are the main source. About 11 million people are exposed to this pollution. OBJECTIVE To examine studies realized about air pollution and its effects on health of the population of São Paulo (Brazil) and methods of assessing exposure to pollution related to traffic. METHODS We performed a literature review us...

The paper deals with the Zagreb Terminal Airspace capacity. The basic scenario has been modelled using the RAMSPlus simulator and capacity has been calculated by using the WMSE method which takes into account the peakhour workload based on air traffic controllers’ tasks. The problem of traffic congestion has been analyzed and several case study scenarios have been simulated. The conducted simul...

Future air traffic systems aim at increasing both the capacity and safety of the system, necessitating the development of new metrics and advisory tools for controllers’ workload in real-time. Psychophysiological data such as Electroencephalography (EEG) are used to contrast and validate subjective assessments and workload indices. EEG used within augmented cognition systems form situation awar...

Today’s air traffic management system is not expected to scale to the projected increase in traffic over the next two decades. Enhancing collaboration between the controllers and the users of the airspace could lessen the impact of the resulting air traffic flow problems. We summarize a new concept that has been proposed for collaborative air traffic flow management, the problems it is meant to...

In high-density urban air mobility (UAM) operations, mitigating congestion and reducing structural constraints are key challenges. Pioneering airspace design projects expect the vehicles to fit into structured UAM corridor networks. However, most existing transport networks not capable of handling increasing traffic demand, which is likely cause congestion, complexity, safety issues. To adapt d...

Problem statement: The reduction in ambient air pollution is a universal goal-particularly in urban areas, the lack of resources often necessitates identification and prioritization of sources of air pollutants. Efficient planning and effective management of environmental pollutants is thus important for optimum utilization of limited resources. Approach: This study examined seven years of data...

A primary function of air traffic flow management is to strategically shape traffic demand to match capacities (e.g., airport arrival/departure rate limits and Sector capacities), without imposing excessive delay. In the current United States National Airspace System (NAS), the disruptions modulating capacities and hence traffic management are predominantly weather events, including convection,...
