Safety Investigation of Crash Rates During Hurricane Evacuations
<p>This study aimed to investigate crash rates across four distinct periods—evacuation, re-entry, emergency, and non-emergency—during Hurricanes Matthew (2016), Irma (2017), and Michael (2018). A notable gap in existing research pertains to understanding crash rates during these critical phases of …

Effectiveness of Mandatory Driver Training Programs for Fire Service Drivers
… is defined by a decrease in the number of crashes per number of runs. Two states were identified for comparison, one with mandatory driver training requirements, Washington State (WA) and the other with no requirements, Pennsylvania (PA). Data was collected from state Department of …

Effects of Age-Related Declines in Visual Motion Processing on Older Driver Safety
… thresholds were associated with number of crashes in the simulator and other indices of unsafe driving. Study 2 examined whether the PMCT-2 could predict older driver performance during a different set of simulated driving scenarios, and whether it was associated retrospectively with real …

Evaluating the Impact of Access Density on Pedestrian and Bicycle Safety
… of access density on pedestrian and bicycle crash rates in urban areas of Florida. Access management, defined as the strategic control of vehicular access points along roadways, plays a crucial role in mitigating conflicts between various roadway users. Previous research has established a …

Characterizing Human Driving Behavior Through an Analysis of Naturalistic Driving Data
Reducing the number of motor vehicle crashes is one of the major challenges of our times. Current strategies to reduce crash rates can be divided into two groups: identifying risky driving behavior prior to crashes to proactively reduce risk and automating some or all human driving tasks using …

Assessing the Safety Impacts of Access Management Techniques
… for analysis of the safety impacts. Although crash rates were not necessarily reduced as a result of the access management techniques, other safety improvements were observed. The raised medians generally reduced the more serious types of collisions, which resulted in a decrease in the …

Deterrence, punishment severity and drink-driving
… an interrupted time-series analysis of road crash rates (Study 1) and an analysis of drink-driving reoffending rates before and after the penalty changes were implemented (Study 2). Study 1 showed a significant increase in a surrogate measure of alcohol-related road crashes after the tougher …

Development of an automated GIS tool to identify and rank high pedestrian crash zones
… United States. Identification of high pedestrian crash zones is an important component to help allocate resources to enhance pedestrian safety by reducing the number and severity of crashes in a cost effective way. High crash zones identify the locations that pose high risks to pedestrians. The …

Optimal Automated Vehicle Piloting: Avoiding Perfection being the Enemy of the Good
… accident-free, it shows potential in reducing crash rates. This work introduces a mathematical framework designed to maximize social welfare through AV pilots, integrating elements such as safety metrics, technology diffusion, and learning effects. The framework’s three models address scenarios …

Efficacy, national/international practices and motivational factors of lifelong driver education for the aging population
… programs to significant reductions in accident rates for seniors. But older driver education has produced certain outcomes that have been indirectly linked to driver safety. Among these secondary outcomes that led to significant reductions in crash rates are increases in self-regulation (i.e., …

A Prioritization Process for Access Management Implementation in Utah
… identifying features, characteristics, and crash history for 175 arterial road segments on Utah state routes. Stepwise linear regression was applied to the data collected to determine which characteristics of the roads were correlated with crash rate, crash severity, and specific collision …

Impact of highway work zones on traffic crashes: A case study in Michigan
… as work zones experience a significant amount of crashes and fatalities each year. To mitigate some of the factors that contribute to these crashes, this paper attempts to deliver guidelines on how to update relevant crash data, identify relevant factors, and create recommendations accordingly. …

Safety Effects Of Traffic Signal Installations On State Road Intersections In Northeast Florida
… how the installations of traffic signals affect crash experience at intersections, to identify those factors which help predict crashes after a signal is installed, and to develop a crash prediction model. It is the intent of this thesis to supplement the Manual on Uniform Traffic Control Devices …
