Examining the effects of site selection criteria for evaluating the effectiveness of traffic safety countermeasures
Regression-to-the-mean Biased estimate Safety index Site selection effects Before–after study Empirical Bayes method
2012/4/26
The primary objective of this paper is to describe how site selection effects can influence the safety effectiveness of treatments. More specifically, the goal is to quantify the bias for the safety e...
Measuring direct and indirect treatment effects using safety performance intervention functions
Intervention models Full Bayes estimation Poisson–lognormal regression Random parameters models Treatment effectiveness index
2012/4/14
Recent traffic safety research has advocated the use of the Full Bayes (FB) approach to conduct controlled before–after safety evaluations. The FB approach was shown to offer both methodological and d...
Propagated failure analysis for non-repairable systems considering both global and selective effects
Reliability Failure propagation Failure isolation Global effect Selective effect
2012/4/22
This paper proposes an algorithm for the reliability analysis of non-repairable binary systems subject to competing failure propagation and failure isolation events with both global and selective fail...
Coupling effects of foam ceramics on the flame and shock wave of gas explosion q
Foam ceramics Gas explosion Flame Shock wave Coupling effects
2012/3/31
The coupling of gas explosion flame and shock wave is analyzed. In the gas explosion process, shock wave is affected by the flame directly, and shock wave also induces the flame. Inhibiting explosion ...
