There is great concern over growing road accidents and associated fatalities. In order to reduce accidents, improve congestion and offer smooth flow of traffic, several measures, such as providing intelligence to transport, providing communication infrastructure along the road, and vehicular communication, are being undertaken. Traffic safety information broadcast from traffic lights using Visi...

Traffic accidents at intersections in urban area are the most common and take a majority of the accident toll. Analysing and generating counter measures has been the major task for traffic safety officials and engineers. Without knowing the safety implications of the counter measures, the task normally concentrates on tackling accidents reflected in historic accident data. As more demand for tr...

One way to cope with the increasing traffic demand is to integrate standard solutions with more intelligent control measures. However, the result of possible interferences between intelligent control or information provision tools and other components of the overall traffic system is not easily predictable. This paper discusses the effects of integrating co-adaptive decision-making regarding ro...

car accidents are documented as a growing public health problem in iran as well as other developing countries. generally growing number of population and vehicles are not accompanied by extending road construction programs. these could be result in high death, disability, and economic loss in such country compare to develop one. this mainly affected young person who are economically more active...

road traffic injuries are known as the most prevalent childhood injury and besides being the greatest cause of child mortality, place an extraordinary burden on health care system. children’s limitation in cognitive, physical and social development makes them more vulnerable in road traffic injuries than adults. their small structure cause challenges to see and be seen and their risk taking beh...

OBJECTIVE To assess whether traffic-calming features are equitably distributed in the UK. DESIGN Cross-sectional database utilising geographical information system (GIS) and population data. SETTING Four large regions in England and Wales, including areas in south Wales, south-west England, east Midlands and Surrey, for which map data were available. MAIN OUTCOME MEASURES The total propor...

In this paper, we show anew image sensor for measuring traffic flow. The image sensor is set at an intersection. The image sensor measures t r af f i c flow by vehicle tracking. The tracking is done by gray level pattern matching. Gray level pattern matching is suitable for outdoor use since it is robust against change of scene brightness. Then we provide the hardware for high speed gray level ...

In this investigation, eight Air Force air traffic controllers (ATCs) performed three scenarios on TRACON (Terminal Radar Approach Control), a computer-based air traffic control (ATC) simulation. Two scenarios were used each with three levels of difficulty. One scenario varied traffic volume by manipulating the number of aircraft to be handled and the second scenario varied traffic complexity b...

1 a. Describe and explain CSFQ, AVQ and XCP. b. Explain the difference between the efficiently and fairness controllers in XCP. c. Discuss three performance measures that can be used to compare these three congestion control strategies. d. Discuss the advantages and disadvantages of these mechanisms with respect to handling Web traffic, UDP traffic, and traffic with specific Quality of Service ...

Performance and Objective Workload Evaluation Research (POWER) was developed to provide objective measures of ATC taskload and performance. POWER uses data extracted from National Airspace System (NAS) System Analysis Recording (SAR) files to compute a set of objective measures. A study was conducted to investigate the relationship of POWER measures with measures of sector complexity, controlle...
