The products of Networked Software must meet customers' business needs in addition to features other than the functional requirements, non-functional characteristics. In order to ensure the system performance, reliability, maintainability and scalability, it is necessary that non-functional conflict digestion method to be optimized so that the higher the efficiency of the implementation of Netw...

This paper presents findings of a research study designed to provide insight into the issue of intent information exchange in constrained en-route air-traffic operations and its effect on pilot decision-making and flight performance. The piloted simulation was conducted in the Air Traffic Operations Laboratory at the NASA Langley Research Center. Two operational modes for autonomous flight mana...

Road traffic accidents are the single greatest cause of fatality in the workplace and the primary cause of all accidental death in the US to the age of 78. However, behavioural analysis of response in the final seconds and milliseconds before collision has been a most difficult proposition since the quantitative recording of such events has largely been beyond cost feasibility for road transpor...

In this paper performance analysis and comparison of a SB (Synchronous Bulk) and FPCF (Forward-Planning Conflict-Free) packet switches is joined with different types of traffic. Real traffic flows were captured in various network environments. Based on real traffic flows, MWM (Multifractal Wavelet Model) and Poisson equivalent synthetic traffic flows were generated. Performance is evaluated by ...

Earlier studies on the subject of subjective judgment of traffic conflicts showed that untrained subjects can reliably judge the dangerousness of filmed traffic conflicts. It was concluded that these judgements were based on a concept of dangerousness. In line with these findings two experiments were conducted. Experiment 1 tested the hypothesis that traffic experts (traffic engineers trained t...

Nowadays, many cities face increasing traffic demand and in conclusion, traffic congestion often becomes chronic and traffic accidents accumulate. One of the main instruments to control the traffic in the road network are traffic signals and they are established to cope with these problems. However, traffic signals are subject to changing requirements and conflicts of goals. In addition, questi...

The objective of this study was to assess the prevalence and determinants of khat chewing, and explore its social, economic and work impacts and examine its relation with road traffic accidents (RTA) among professional drivers in Jazan region, Saudi Arabia. A cross-sectional study was conducted on 215 drivers recruited from transport stations in Jazan region by random cluster sampling. An inter...

This document discribes different optimization methods applied to the air traffic management domain. The first part details genetic algorithms and introduces a crossover operator adapted to partially separated problems. The operator is tested on an airport ground traffic optimization problem. In the second part, the conflict resolution problem is optimized with different (centralized or autonom...
