Effects of emergency medical services times on traffic injury severity: A random effects ordered probit approach

open access: yesTraffic Injury Prevention, 2018
Objective: Emergency medical services (EMS) play a vital role in the postcrash effort to reduce fatalities by providing first aid treatment and transportation to medical facilities. This study aims to analyze the time required for crash reporting and EMS arrival in fatal traffic crashes and to explore the effects of EMS time on the traffic injury ...

Korean Welfare Panel Data: A Computational Bayesian Method for Ordered Probit Random Effects Models [PDF]

open access: yesCommunications for Statistical Applications and Methods, 2014
We introduce a MCMC sampling for a generalized linear normal random effects model with the ordered probit link function based on latent variables from suitable truncated normal distribution. Such models have proven useful in practice and we have observed numerically reasonable results in the estimation of fixed effects when the random effect term is ...

Exploring injury severity of pedestrian-vehicle crashes at intersections: unbalanced panel mixed ordered probit model

open access: yesEuropean Transport Research Review, 2021
Although the pedestrian deaths have been declining in recent years, the pedestrian-vehicle death rate in Croatia is still pretty high. This study intended to explore the injury severity of pedestrian-vehicle crashes with panel mixed ordered probit model ...

Firm-related training tracks: a random effects ordered probit model [PDF]

open access: yesEconomics of Education Review, 2003
A random effects ordered response model of training is estimated to analyze the existence of training tracks and time varying coefficients in training frequency. Two waves of a Dutch panel survey of workers are used covering the period 1992-1996. The amount of training received by workers increased during the period 1994-1996 compared to 1992-1994 ...

Effects of design consistency measures and roadside hazard types on run-off-road crash severity: Application of random parameters hierarchical ordered probit model

open access: yesAnalytic Methods in Accident Research, 2023
Run-off-road crashes are one of the most significant causes of road deaths worldwide. Given such significant safety concerns, a number of earlier studies examined the critical factors contributing towards run-off-road crash severity outcomes, mostly by using the information compiled in the official crash database.

Investigation on the Injury Severity of Drivers in Rear-End Collisions Between Cars Using a Random Parameters Bivariate Ordered Probit Model

open access: yesInternational Journal of Environmental Research and Public Health, 2019
The existing studies on drivers’ injury severity include numerous statistical models that assess potential factors affecting the level of injury. These models should address specific concerns tailored to different crash characteristics.

Analysis of the impacts of risk factors on teenage and older driver injury severity using random-parameter ordered probit

open access: yesCanadian Journal of Civil Engineering, 2020
The study analyzed injury severity of teenage and older drivers using 2015–2016 crash data from New Mexico. The fitness of the random-parameter ordered probit models developed for each age group was tested using likelihood ratio, comparing them to a ...
