“…For example, a triaxial accelerometer [8] was used to measure the acceleration and global positioning system (GPS) was used to obtain position detection. After data collection, they designed an embedded system (hardware, firmware, and software) to assess the dynamic motion factors that affect the comfort in public transportation systems.…”

“…But the improvement value is neglected in practice, because the calculation approach is incomplete and the basic data are hard to obtain. Most of the current theoretical researches are devoted to establishing the index system which influences the passenger comfort [5,6], exploring the comfort range of one exact factor [7], introducing some high technologies and facilities that are helpful to obtain the passenger comfort parameters accurately and easily [8,9], or studying the relationship between the passenger comfort and transportation management [10]. There are no quantitative & Wencheng Huang 1261992248@qq.com 1 calculation approaches to calculate passenger comfort benefits, so it is important to find out a new approach, which can be used both in theoretical research and engineering practice.…”

A comfortable environment in railway passenger coaches can be regarded as a resource for social consumption during the transport process. Railway passenger comfort benefits (RPCBs) can be regarded as a special generalized cost. In this paper, we select a series of objective and subjective indexes to formulate a quantitative method of calculating the RPCB with considering ticket fares. This method includes three steps: make the initial data dimensionless, calculate the weight of each index, and finally calculate the RPCBs. The proposed method was validated with the data collected from two types of trains: G13 from Beijing South to Shanghai Hongqiao and T109 from Beijing to Shanghai. Also, questionnaire survey was conducted in both trains. After data processing, the results show that there is a linear relationship between the RPCB and ticket fare with a correlation coefficient of 0.9616.

“…In [18], Castellanos and Fruett constructed an embedded system in which the acceleration and jerk magnitudes were used to evaluate the passenger comfort in public transportation. By taking the derivative of (2) with respect to time, the acceleration function of train decelerating operation can be gotten as follows:…”

Only the actual following distance that is a little greater than the optimum safety following distance at any time can make the following train move in safety and efficiency. For this purpose, a new calibration method is studied for the real-time calculation of the dynamically optimum safety following distance. To cope with the complex situations of train following operation, the mathematic model of train deceleration operation based on the hyperbolic function with a variable acceleration control strategy is established to simulate the speed-changing behavior of high-speed train steered by the well-experienced driver. Using the evaluation of train behavior adjustment quality and the numerical analysis theory, we build the fitting function of the optimum absolute safety following distance changing with the following train's velocity for the real-time calibration of safe following distance under absolute braking mode. And then, we discussed the real-time calculation of the optimum safety following distance under relative braking mode (i.e., the relative safety following distance). The study results will help a high-speed train to evaluate and optimize its own following behavior according to the current operation states of train following system, the actual following distance, and the absolute or relative safety following distance. The actual following distance is rationally controlled by the scientific adjustment of the following train's behavior so that train following movement can be always safe, efficient, and smooth (comfortable).

Over the last twenty years, the railways in Britain have seen rapid growth, with patronage doubling and the level of train service increasing by 50%. However, these successes have also led to challenges. In particular real unit costs are estimated to have increased by 50%, with particularly marked increases in infrastructure renewal and enhancement costs. Against this background, the University of Southampton have been leading the Track 21 and Track to the Future projects, funded by the Engineering and Physical Sciences Research Council. These projects are assessing how to make ballasted track systems more durable given higher traffic levels and how to reduce the costs of maintenance and renewal.Track 21 considered a number of engineering interventions of which this paper focusses on one, under sleeper pads (USPs). The cost implications of this intervention are assessed for the South West Main Line using an industry-specific model, VTISM (vehicle track interaction strategic model), adapted in two ways. First, the results of laboratory experiments from specialist test rigs are incorporated into the model. Secondly, the wider effects of increased reliability, improved ride quality and reduced vibration are also considered within a cost-benefit analysis framework. It is found that USPs can lead to substantial financial savings and, depending on assumptions concerning noise impacts, are likely to have substantial wider social benefits.
