Release Risk and Optimization of Railroad Tank Car Safety Design

The performance metric for tank cars and other hazardous materials vehicles involved in accidents has generally been conditional probability of release given involvement in an accident. This metric considers the probability of a release event occurring but does not take into account the quantity of product lost in a release incident. In this paper, a new metric termed “release risk” is introduc...

A Numerical Model for Railroad Freight Car-to-Car End Impact

A numerical model based on Lagrange-D’Alembert principle is proposed for car-to-car end impact in this paper. In the numerical model, the friction forces are treated by using local linearization model when solving the differential equations. A computer program has been developed for the numerical model based on Runge-Kutta fourth-order method. The results are compared with the Multibody Dynamic...

When caring stops, staffing doesn't really matter.

How well do we understand the people side of staffing, and do we recognize the importance therein? Delivering care without caring is simply wrong. Health care leaders must take this concern seriously and find ways to invest in and set up structures that support healthy processing, by individual caregivers, of the many emotional situations that are a natural part of care delivery. Individual car...

Car Delay Model near Bus Stops with Mixed Traffic Flow

This paper proposes a model for estimating car delays at bus stops under mixed traffic using probability theory and queuing theory. The roadway is divided to serve motorized and nonmotorized traffic streams. Bus stops are located on the nonmotorized lanes. When buses dwell at the stop, they block the bicycles. Thus, two conflict points between car stream and other traffic stream are identified....
