With the rapid development of high-speed railway and the changes of the tourists’ requirement, it is imperative to the integrate advantages of aviation and rail. This paper constructs the air-rail integration model based on the current development situation and characteristics of Chinese railways. In allusion to the search problem of connecting path in air-rail integration network, a constraine...
In our Rail Human Factors approach, we define the human as the starting point for our interdisciplinary research on the design of human-machine interfaces in railway systems. One key focus of this approach is on the future workplace of the rail traffic controller. In this paper, a collaboration project between human factors scientists and trained rail traffic controllers is presented. Based on ...
This paper focuses on the problem about how to efficiently process the emergency of rail transit and guarantee the lowest accident loss in a short period of time, which is the urban rail transit management policy that makers are faced with, and which develops a high integrated system with strong information based on contingency plans to give the decision aid of urban rail transit emergency even...
What do you do to start reading rail human factors around the world impacts on and of people for successful rail operations? Searching the book that you love to read first or find an interesting book that will make you want to read? Everybody has difference with their reason of reading a book. Actuary, reading habit must be from earlier. Many people may be love to read, but not a book. It's not...
This paper presents the responses of the railway vehicle and track components in terms of contact forces and displacements. The considered vehicle model is a five-DOF pitch-plane lumped parameter quarter car model supported on two-dimensional track systems comprising three layers. The car body is linked with the vehicle bogie through secondary suspension springs and damper elements, which is fu...
Low-voltage low-power comparators implemented in standard digital processes are of increasing importance in different integrated applications. In this paper a 1-V fully-differential lowpower MOSFET-only comparator with rail-to-rail input swing is presented which can be suitably used in very low-voltage lowpower pipelined A/D converters. This comparator utilizes a resistive divider configuration...
Rail corrugation is a phenomenon that leads to a waving in the rails with wavelengths typically between 3 cm and 100 cm and amplitude levels of several microns. The genesis of this waving is complex. Rail corrugation is a recognized problem that leads to excess vibration on the rails and vehicles to a point of reducing their life span and compromising safety. In urban areas excess vibration noi...
The objective of this study was to make a comparative evaluation of mainline and sub-urban rail vehicles in terms of ergonomic variables of Safety and Comfort. As an end result the objectives were also to make recommendations for the rail vehicle manufacturers industry for future vehicle design. The results of the evaluation allowed us to draw some conclusions and recommendations about future r...
This paper examines the impact of a new light rail system on single-family housing values in Charlotte, North Carolina, from 1997 to 2008. We use a Hedonic Price Analysis (HPA) to estimate how proximity to light rail, housing characteristics, and spatial components (at a block group level) affect single-family housing values. The same method is applied to each of the four time periods (t1, t2, ...
An ultra-low voltage rail-to-rail operational trans conductance amplifier (OTA) based on a standard digital 0.18μm CMOS process is described in this paper. Techniques for designing a 0.6 volt fully differential OTA are discussed including bias and reference current generator circuit. To rail-to-rail operation complementary input differential pairs are used where Bulk driven technique is used to...
