Enhancing Road Safety through Machine Learning for Prediction of Unsafe Driving Behaviors
… study addresses two crucial challenges in road safety: analyzing traffic intersections to enhance safety by predicting potentially risky situations, and monitoring driver activity to prevent distracted driving accidents. Focusing on Virginia's intersections, we thoroughly examine traffic …

An Analysis of Emergency Vehicle Crash Characteristics
Crash data suggests that intersections are areas producing conflicts among the various road users because of entering and crossing movements. Traffic signal control systems may not always be sufficient in preventing collisions at intersections between emergency and other vehicles. The Firefighter …

3D Object Detection for Road Safety at Urban Intersections
Road safety is a critical issue, with road trauma resulting in 1.25 million fatalities and 50 million injuries annually worldwide. Using crash data and traditional methods, it can take years and even decades to collect enough data to evaluate the safety of complex road infrastructure, such as …

Evaluation of Traffic Operations at Intersections in Malfunction Flash Mode
… volume conditions. In order to assess the safety implications of these events and improve the process by which the mode of flash (yellow/red versus red/red) is selected, the research contained in this study evaluated driver behavior and the operational characteristics of intersections …

Effectiveness of Saskatchewan Government Insurance 2014 Traffic Safety Initiatives on Reducing Casualties
… as a result of the worsening state of road safety in Saskatchewan. A Special Committee on Traffic Safety was formed to enhance road safety by examining the dominant factors that cause traffic collisions in the province: impaired driving, distracted driving, excessive speed, intersection …

Development of a Threat Assessment Algorithm for Intersection Collision Avoidance Systems
Relative to other roadway segments, intersections occupy a small portion of the overall infrastructure; however, they represent the location for nearly 41 % of the annual automotive crashes in the United States. Thus, intersections are an inherently dangerous roadway element and a prime location …

Effects of Intersection Lighting Design on Driver Visual Performance, Perceived Visibility, and Glare
Nighttime intersection crashes account for nearly half of all the intersection crashes, making them a major traffic safety concern. Although providing lighting at intersections has proven to be a successful countermeasure against these crashes, existing approaches to designing lighting at …

A Framework and Analytical Methods for Evaluation of Preferential Treatment for Emergency and Transit Vehicles at Signalized Intersections
… priority for transit vehicles at signalized intersections. EV preemption employs technologies and signal control strategies seeking to reduce emergency vehicle crash potential and response times. Transit priority employs the same technologies with signal control strategies seeking to reduce …

Analysis and prediction of traffic accidents at urban intersections
… distance oscillation, on both traffic flow and intersection safety. A data-driven approach is proposed for identifying the Pareto optimal sets of parameter combinations that both maximise the flow volume and minimise the risk of crashes. The analysis of traffic flow is conducted by considering …

Investigating Violation Behavior at Intersections using Intelligent Transportation Systems: A Feasibility Analysis on Vehicle/Bicycle-to-Infrastructure Communications as a Potential Countermeasure
The focus of this dissertation is on safety improvement at intersections and presenting how Vehicle/Bicycle-to-Infrastructure Communications can be a potential countermeasure for crashes resulting from drivers' and cyclists' violations at intersections. The characteristics (e.g., acceleration …

Neural Network Trees And Simulation Databases: New Approaches For Signalized Intersection Crash Classification And Prediction
Intersection related crashes form a significant proportion of the crashes occurring on roadways. Many organizations such as the Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO) are considering intersection safety improvement as …

Safety, Operational, and Energy Impacts of In-Vehicle Adaptive Stop Displays Using Connected Vehicle Technology
Driving through an un-signalized intersection creates multiple opportunities for missed or misunderstood information. Stop signs, in particular, can be stolen, covered by vegetation, or rotated out of place, leading to an absence of information, contributing to inappropriate decision-making and …

Evaluation of the Effectiveness of Blank-Out Overhead Dynamic Advance Warning Signal Systems
… installed upstream of a high-speed signalized intersection (HSSI) warn motorists of impending signal changes in an effort to reduce the frequency of red-light running (RLR) and crashes. A new advance warning signal design was tested on an approach to an HSSI in Utah to study the effects of the …

Evaluation of the Applicability of the Interactive Highway Safety Design Model to Safety Audit of Two-Lane Rural Highways
The Interactive Highway Safety Design Model (IHSDM) is a suite of software developed by the Federal Highway Administration (FHWA) for monitoring and analyzing two-lane rural highways in the United States. As IHSDM is a fairly "young" program a limited amount of research has been conducted to …
