This work contributes to study the application of extreme value theory (EVT) in road safety analysis, estimating the risk of being involved in an entering–circulating collision in single-lane roundabouts. Detailed trajectory data of the vehicles were derived from a driving simulator experiment, and the time-to-collision (TTC) was used as a surrogate measure of safety. Three EVT approaches were applied, tested and compared: (1) the Generalized Extreme Value distribution used in the block maxima… Expand
Safety analysis of unsignalized intersections: a bivariate extreme value approach
ABSTRACT Application of extreme value theory (EVT) to road safety analysis is gaining interest, thanks to its ability to produce quick and reliable safety evaluations without the use of crash data.Expand

Road safety of passing maneuvers: A bivariate extreme value theory approach under non-stationary conditions.
This work applies the Block Maxima method and estimates several extremal univariate and bivariate models, including the logistic copula, and shows that accounting for driver specific characteristics and road infrastructure variables improve the head-on and rear-end collision probabilities estimation.

Validating the Bayesian hierarchical extreme value model for traffic conflict-based crash estimation on freeway segments with site-level factors.
The model was applied to data of lane change conflicts collected from 11 basic freeway segments in Guangdong Province, China and showed that Bayesian hierarchical extreme value models significantly outperform the at-site models in terms of crash estimation accuracy and precision. Expand

A bivariate Bayesian hierarchical extreme value model for traffic conflict-based crash estimation
A bivariate Bayesian hierarchal extreme value modeling method is developed that consists of a bivariate extreme value model that integrates different conflict indicators in a unified framework and a Bayesian hierarchical structure that combines traffic conflicts of different sites and accounts for heterogeneity in conflict extremes.

Freeway safety estimation using extreme value theory approaches: a comparative study.
The comparison of results from the two modeling approaches indicates that the POT approach performs better than BM approach from the aspects of data utilization, estimate accuracy and estimate reliability, and much more robust estimated return levels are recommended for freeway safety evaluation.

Roundabouts have been used widely on all road classes in the United Kingdom because they are considered safer than other types of intersections in general. The objective of this study was to examineExpand
Using Extreme Value Theory for the Prediction of Head-On Collisions During Passing Maneuvres
The Generalized Extreme Value distribution as an EV method using the minimum time-to-collision with the opposing vehicle during passing maneuvers achieves good fit with respect to head-on collisions' prediction indicating that this is a promising approach for safety evaluation. Expand

The extreme value theory approach to safety estimation.
A novel application of the extreme value theory to estimate safety is proposed, considered proactive in that it no longer requires historical crash data for the model calibration and evaluated by applying it to right-angle collisions at signalized intersections. Expand
