Perceived service quality in bus transit service: A structural equation approach
TL;DR: The Overall Service Quality of a public transport system has been jointly explained by these two overall evaluations when a Structural Equation Model (SEM) approach is adopted.
Journal ArticleDOI
Analysis of traffic accident injury severity on Spanish rural highways using Bayesian networks
TL;DR: An analysis of 1536 accidents on rural highways in Spain is presented, where 18 variables representing the aforementioned contributing factors were used to build 3 different BNs that classified the severity of accidents into slightly injured and killed or severely injured.
Journal ArticleDOI

Juan de Oña,Rocío de Oña +1 more
TL;DR: This paper seeks to summarize the evolution of research and current thinking as it relates to the different methodological approaches for SQ evaluation in the PT sector over the years and to provide a discussion of future directions.
Journal ArticleDOI
Analysis of traffic accidents on rural highways using Latent Class Clustering and Bayesian Networks
TL;DR: Bayesian Networks (BNs) are used to identify the main factors involved in accident severity for both, the entire database (EDB) and the clusters previously obtained by LCC and the results show that the combined use of both techniques is very interesting as it reveals further information that would not have been obtained without prior segmentation of the data.
Journal ArticleDOI
Analysis of traffic accident severity using Decision Rules via Decision Trees
TL;DR: This study focuses on traffic accident data from rural roads in Granada (Spain) from 2003 to 2009 and shows that it can obtain more than 70 relevant rules from the data using the new method, whereas with only one DT the authors would have extracted only five relevantrules from the same dataset.
