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...
متن کاملA 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...
متن کاملAnalysis of Braking and Steering Performance in Car- Following Scenarios
This paper presents recent results of on-going research to build new maps of driver performance in car-following situations. The novel performance map is comprised of four driving states: low risk, conflict, near crash, and crash imminent – which correspond to advisory warning, crash imminent warning, and crash mitigation countermeasures. The paper addresses two questions dealing with the appro...
متن کاملOptimizing Railroad Tank Car Safety Design to Reduce Dangerous Goods Transportation Risk
This paper describes an optimization model developed to determine the most efficient way to enhance the safety design of tank cars used to transport toxic inhalation hazard (TIH) materials in North America and a quantitative risk analysis conducted to assess the risk and potential benefit of implementing enhanced safety-design tank cars. The conditional probability of release and the car's weig...
متن کاملNAPL source zone depletion model and its application to railroad-tank-car spills.
We developed a new semi-analytical source zone depletion model (SZDM) for multicomponent light nonaqueous phase liquids (LNAPLs) and incorporated this into an existing screening model for estimating cleanup times for chemical spills from railroad tank cars that previously considered only single-component LNAPLs. Results from the SZDM compare favorably to those from a three-dimensional numerical...
