Slab track is generally noisier than conventional ballasted track, so noise control measures that can be applied to a slab are of great importance. Several treatments have been studied under controlled conditions through experiments on 1:5 scale model with and without the presence train body. These consist absorptive rubber mats surface low barrier introduced close track. The reduction evaluate...

An experimental approach to road mitigation that maximizes inferential power is essential to ensure that mitigation is both ecologically-effective and cost-effective. Here, we set out the need for and standards of using an experimental approach to road mitigation, in order to improve knowledge of the influence of mitigation measures on wildlife populations. We point out two key areas that need ...
