(author), Wändell, J. (author)The noise produced during a train pass-by originates from several different sources such as propulsion noise, noise from auxiliary equipment, aerodynamic noise and rolling noise. The rolling noise is radiated by the wheels and the track and is excited by the wheel and rail unevenness, usually referred to as roughness. The current TSI Noise...article 2018

Martens, M.H. (author), Fox, M. (author), TNO Defensie en Veiligheid (author)Fixation times are known to decrease after multiple exposures to the same road in simulated environments. The present study investigates whether this also holds for real driving and for watching a video, which was taped during driving (while simulating steering and braking). It appeared that the fixation times for traffic signs, information...article 2007

Monk-Steel, A.D. (author), Thompson, D.J. (author), de Beer, F.G. (author), Janssens, M.H.A. (author), TNO Industrie en Techniek (author)Curve squeal noise is of growing concern for the railway industry as rail systems become more widespread in densely populated areas. In response to the pressure to minimise environmental pollution, there is a demand for a deeper understanding of the phenomenon and to develop a methodical approach to managing the wheel-rail system. Under curving,...article 2006

Miedema, H.M.E. (author), Instituut voor Ruimtelijke Organisatie TNO (author)Relationships between exposure to noise [metric: day-night level (DNL) or day-evening-night level (DENL)] from a single source (aircraft, road traffic, or railways) and annoyance based on a large international dataset have been published earlier. Also for stationary sources relationships have been assessed. Here the annoyance equivalents model...article 2004

Claessens, M.T. (author), van Dijk, N.M. (author), Zwaneveld, P.J. (author), Instituut voor Ruimtelijke Organisatie TNO (author)We consider the problem of cost optimal railway line allocation for passenger trains for the Dutch railway system. At present, the allocation of passenger lines by Dutch Railways is based on maximizing the number of direct travelers. This paper develops an alternative approach that takes operating costs into account. A mathematical programming...article 1998
