Many long-span bridges have been built throughout the world in recent years but they are often subject to multiple types of dynamic loads, especially those located in wind-prone regions and carrying both trains and road vehicles. To ensure the safety and functionality of these bridges, dynamic responses of long-span bridges are often required for bridge assessment. Given that there are several ...

Transportation planning models are typically used to estimate future traffic patterns, peak period traffic, travel time, and various environmental or other related traffic flow characteristics. Unfortunately, traffic safety is seldom, if ever, explicitly considered proactively during the transportation planning process. This omission is attributed to various factors, including the lack of avail...

Driver fatigue remains a significant cause of motor-vehicle accidents worldwide. New technologies are increasingly utilised to improve road safety, but there are no effective on-road measures for fatigue. While simulated driving tasks are sensitive, and simple performance tasks have been used in industrial fatigue management systems (FMS) to quantify risk, little is known about the relationship...

Quantitative risk assessment (QRA) models are used to estimate the risks of transporting dangerous goods and to assess the merits of introducing alternative risk reduction measures for different transportation scenarios and assumptions. A comprehensive QRA model recently was developed in Europe for application to road tunnels. This model can assess the merits of a limited number of "native safe...

Much research that occurs within the field of traffic psychology leads to the development of effective road safety countermeasures. There may, however, be psychological research being undertaken in other domains, such as aviation or mining, that has the potential to both provide new directions for, and enhance the effectiveness of, current road safety countermeasures. The purpose of this report...

Vehicle dynamic safety warning system based on data fusion is researched and designed in this paper. Dynamic information of vehicle, road and environment can be collected in real time. By analyzing and processing these data, active safety warning information is achieved for individual vehicle on different work condition. Security characteristic parameter, road conditions and traffic meteorologi...

The last decade has seen a large amount of road safety effort put into investigating the socalled ‘older driver problem’. As a consequence, our knowledge of older drivers and their functional performance, their driving and crash patterns and their crash risk, has increased substantially. However the research has given little direct attention to the special challenges that older drivers pose to ...

objectives: self-assessment, as one type of alternative assessment, with the increased attention to learner-centered curricula, needs analysis, and learner autonomy has gained popularity in recent years. the aim of this study was to investigate the effect of self-assessment on javanroodian foreign language (kordestan) learners’ oral performance ability. methods: the assessment program involved ...
