Mitigating the Severity of Level Crossing Accidents and Derailments

道口和重型公路车辆数量的不断增加导致道口事故和脱轨更加频繁和严重。尽管使用了主动预警系统，但澳大利亚每年平均发生100起平交事故。为了缓解这些碰撞，本研究旨在通过改变公路和铁路道口的水平，并在这些改进的平交道口的凹槽中设置护栏，来制定降低碰撞能量和有效的车轮约束以防止脱轨的理论。这些理论旨在利用非线性动态计算方法和实验室实验来发展。预计这些结果将能够降低平交事故的严重性，从而挽救脱轨的生命和成本。

Ongoing increases in the number of level crossings and heavy road vehicles cause more frequent and severe level crossing accidents and derailments. Despite the use of active warning systems, each year, on average, 100 level crossing accidents occur in Australia. With a view to mitigating these crashes, this research aims to formulate theories for reduction in crash energy and effective wheel constraints to prevent derailment by modifying the levels of road and rail crossings and providing guard rails in the recesses of these modified level crossings. The theories are intended be developed using nonlinear dynamic computational methods and laboratory experiments. The outcomes are expected to enable reduction in the severity of level crossing accidents and hence save lives and costs of derailment.
