Many factors were found to affect the operating speed, such as, radius of horizontal curve or curvature change rate, grade, length of horizontal curve, deflection angle, sight distance, superelevation rate, side friction factor, and pavement conditions (Boscaino, Pratico 2001; Pratico et al.

This is very important for traffic safety and for lowering the expenses of railway repair and supervision, because even small changes can sometimes cause derailment, for example, superelevation can markedly change acting forces and vehicle behaviour having a negative impact on rolling stock wheels and rail wear.
A sampling of topics: modeling tree-induced effects on pedestrian exposure to road traffic pollution, biofuels, improving safety and sustainability of urban transport surfaces through the recycling of reclaimed extinguishing powders, analysis of the interaction between travel demand and rail capacity constraints, tunnel lighting design, urban car sharing, online monitoring of essential components of rail transport, evaluating superelevation in relation to drainage requirements and vehicle dynamics, and a design framework for measuring transit oriented development.
Due to the resonance effect a superelevation of the amplitude is done with resulting elevation values between about 1.
Topics addressed include alignment of railway lines, track maintenance and renewal, concrete sleepers, cures and superelevation, suburban railways in metro cities, signaling and interlocking, and tunneling, among other topics.
v]) [approximately equal to] 0,9[degrees] Horizontal Alignment The design of road curves should take into account the relationship between design speed and curvature, and how these relate to superelevation and friction.
According to his new model, it's far more likely that the highest flow marks reflect superelevation of a 3-to-10-m-deep flow of snow that raced around and up the side of the curve during an avalanche lasting about 23 seconds.
To my mind it is very important that we admit this superelevation in the very order of nature.
