Real-Time Framework to Predict Crash Likelihood and Cluster Crash Severity

Transportation Research Record: Journal of the Transportation Research Board, 2023
This study proposes a three-stage framework for real-time crash likelihood and severity prediction. Firstly, a real-time crash likelihood prediction model was developed. Secondly, a real-time crash severity clustering model was proposed to cluster the crashes into different severity levels. Thirdly, a severity clustering validation model was developed

Impact of pavement conditions on crash severity

Accident Analysis & Prevention, 2013
Pavement condition has been known as a key factor related to ride quality, but it is less clear how exactly pavement conditions are related to traffic crashes. The researchers used Geographic Information System (GIS) to link Texas Department of Transportation (TxDOT) Crash Record Information System (CRIS) data and Pavement Management Information System

Evaluation of Vehicle-Based Crash Severity Metrics

Traffic Injury Prevention, 2015
Vehicle change in velocity (delta-v) is a widely used crash severity metric used to estimate occupant injury risk. Despite its widespread use, delta-v has several limitations. Of most concern, delta-v is a vehicle-based metric which does not consider the crash pulse or the performance of occupant restraints, e.g. seatbelts and airbags.

Combined Crash Frequency–Crash Severity Evaluation of Geometric Design Decisions

Transportation Research Record: Journal of the Transportation Research Board, 2015
This paper quantified the effects of freeway ramp spacing and auxiliary lane presence on crash frequency and crash severity. Crash frequencies were predicted with a safety performance function, and crash severities were estimated with what was termed a “severity distribution function.” The paper then demonstrated how to combine quantitative knowledge ...

Urban Streetscape Design and Crash Severity

Transportation Research Record: Journal of the Transportation Research Board, 2015
Streetscape design is increasingly acknowledged as a tool for improving traffic safety and livability in urban settings. While traditional highway safety engineering promotes removing obstacles from and widening roadside clear zones to reduce collision potential, a contrasting framework proposes that smaller, more enclosed streetscapes may encourage ...

Multilevel Discrete Outcome Modeling for Crash Severity: A Novel Approach for Crash Severity Models

Transportation Research Record: Journal of the Transportation Research Board
Combining a total crash count model and a crash severity probability model simultaneously to predict crashes by severity is challenging because crash count models are implemented at an aggregate scale, that is, by sites (segments or intersections), while crash severity probability models are at a disaggregate scale, that is, by crashes or persons ...

Developing Truck Corridor Crash Severity Index

Transportation Research Record: Journal of the Transportation Research Board, 2013
According to NHTSA, more than 400,000 truck accidents occurred in 2009 and approximately 7,800 of those were fatal crashes. Compared with extensive studies conducted on freeway truck safety, the research on arterial streets is considerably disproportionate. Making the connections between truck traffic generators, arterial streets are key links in door-

Influential factors for severe traffic crashes

Proceedings of 2011 IEEE International Conference on Vehicular Electronics and Safety, 2011
Transportation safety is of great concerns in our daily life. Both passive safety systems (such as seatbelt) and active safety systems (such as adaptive cruise control, i.e., ACC) have been proposed to reduce traffic accidents, especially in mitigating severity of an accident.

PTSD after severe vehicular crashes.

Annals of advances in automotive medicine. Association for the Advancement of Automotive Medicine. Annual Scientific Conference, 2011
To describe predictors of PTSD after motor vehicle crashes (MVC).MVC patients were interviewed during their hospitalization and at 6 and 12 months post-injury. Interviews included information about behavioral factors, circumstances around the crash, recovery and PTSD screening.

Bayesian hierarchical modelling of traffic barrier crash severity

International Journal of Injury Control and Safety Promotion, 2020
Severe vehicle crashes have resulted in a large-scale social and economic loss. As a result, the reduction of those crashes has become one of the key objectives of policy makers. Although traffic barriers have been utilized to reduce the run-of-road crash severity, still those crashes account for a high number of severe crashes.
