Résumé :

The need for shared freight and passenger rail corridors in the United States is increasing due to the growing demand for regional and intercity passenger transport. Several researches have been conducted on reducing the risk of freight train accidents, but little research has been done on the risk of passenger train accidents. The accident rates of passenger trains have declined in the past two decades; however, faster and more frequent passenger train services require even higher safety standards, and therefore further reduction to the risk of passenger train accidents is needed. The research presented in this paper analyzed the passenger train accidents in the United States using the Federal Railroad Administration train accident database to understand the trend of passenger train accident rates, the frequency and severity of different types of accidents, and to explore the major factors that cause them. Derailments and collisions were identified as the most significant types of passenger train accidents, and track failures and human factors, respectively, were the primary causes of those accidents. Accidents caused due to human factors and train operations such as train speed violations and failure to obey signals are often high-consequence accidents and therefore pose the greatest risk. Higher risk infrastructure-related factors include track geometry defects and broken rails or welds. This study on passenger train accidents provides a solid foundation for further research on improving the safety of passenger rail and shared-use rail corridors.

Résumé :

Spin training has not been required for students working towards their private or commercial certificates for the past 70 years. Switching to a stall-prevention mindset within training aimed to make spin recovery unnecessary; however, stall-type accidents, consisting of stalls, spins, and spirals, still occur and are highly fatal. Although past studies have analyzed accidents, interviewed pilots at different levels, and made recommendations for changes in the industry, stall-type accidents are no less fatal now, at a fatality ratio of approximately 40–50% yearly. The research discussed in this paper aims to summarize and present accident stall-type statistics in aggregate over the past five decades and motivate future pilot- and training-centered research to address the high presence of stall-type accidents in aviation. Specifically, this article uses NTSB accident reports to answer the research question of whether there have been changes in the prevalence of spins among both fatal and non-datal fixed-wing accidents in the United States over the past sixty years. The methodology breaks down the accident analysis in three groups, based on the time period in which they occurred, due to differences in the reporting methods used. This paper finds that the prevalence and fatality ratio of stall-type accidents has remained high over the past six decades and that stall-type accidents are more than twice as fatal as an average accident. To remedy the high accident count, we recommend experimental ground and simulator-based training to improve pilot knowledge, skill, and performance.

Résumé :

Rules and regulations for accident mitigation have been implemented between all players. It is necessary to use new technologies and resources for human factors to mitigate future accidents to decrease accidents. It has been verified that accidents by sabotage are currently non-existent and that most of the fatalities are during the flight and in the runway approach phase. Severe accidents with associated fatalities are a small number that tend to decrease over time. Human errors, although with all the mitigations over time, are still the most significant cause of accidents; although accidents have decreased, other factors may be related to this type of error, such as the lack of personnel for the operation of a flight. Accidents can also be related to other factors, such as economic factors. GDP growth is positively correlated with accidents, and inflation is negatively correlated. It is also found that the inflation factor is also related to the number of flights due to a lack of demand.

Résumé :

Tree work has a high accident rate compared to many other occupations. News accounts of recent accidents can be easily accessed through the internet, though this may not provide a true picture of the number and types of accidents occurring. U.S. government bureaus and agencies have produced reports citing the number and circumstances of fatal accidents in the profession. The government’s information is obtained from many sources and may not accurately identify types or frequency of these accidents. A survey of the accidents and safety training among tree care companies was conducted using a mail questionnaire based on the Tailored Design Method. The company managers responding to the survey overwhelming identified having trained field workers as very important yet only about two-thirds of their companies conducted any training. The training most often conducted was on aerial lifts, chain saws, and chipper, which was provided by company employees in a field setting. Driver’s training was not part of a formal safety program for most of the companies. Aerial rescue was practiced by about one-fourth of the surveyed companies. The most common fatal accidents involved contact with an electrical conductor followed by being struck by a falling limb. The relative number of fatal accidents by event or exposure in this survey was similar to that identified by two federal government reports on fatal accident in the field.

Résumé :

Roundabouts have become popular in Australia and many countries in Europe during the past few decades. In the United States of America, however, roundabouts are just beginning to be recognized as an alternative treatment for roadway intersections. An effort was made to collect traffic and traffic crash data for existing roundabouts in the United States and to perform a statistical analysis to determine the effectiveness of roundabouts as a treatment for intersecting roadways. General information about thirteen roundabouts located in Maryland, Florida, Nevada, and California was collected and is included for readers’ use. In addition, six retrofitted roundabout sites with accident data ranging from 1 to 3 years before and after were analyzed. In all but one case, the reduction in accidents for roundabout sites was in the range of 60 to 70 percent. A chi-squared test and a normal approximation test were performed using the accident data from these six roundabout sites. Both of these tests indicated a significant difference in the reduction of frequency and mean of accidents at 95 and 99 percent confidence levels, respectively, between pre-roundabout and post-roundabout periods. Results, though limited, are encouraging and in line with findings of past European and Australian studies involving roundabouts. Additional studies on the safety performance of U.S. roundabouts should be conducted in the future when more data are available to reinforce these findings.

Résumé :

Since the enactment of the Occupational Safety and Health Act in 1981, the Korea Occupational Safety and Health Agency has endeavored to prevent fall accidents in the construction industry. However, many fatalities still occur in the South Korean construction industry. Meanwhile, the United States improved various systems and conducted studies to prevent fall accidents, significantly reducing such occurrences in the construction industry. The objective of this study is to present improvements to South Korea’s fall prevention technology by analyzing the laws and programs of the United States. To achieve this, this study has analyzed the United States’ fall prevention technology and derived improvements applicable in South Korea through an expert opinion survey. This study suggests to (1) set the height standard of a fall accident to 2 m, (2) adopt an active fall prevention system, (3) create a map of fallen fatalities, and (4) employ safety experts to support foreign workers. In the future, the results of this study are expected to be used as basic data for policies and programs related to fall accidents in the construction industry.

Résumé :

Inflight loss of control (LOC-I) is a significant cause of General Aviation (GA) fixed-wing aircraft accidents. The United States National Transportation Safety Board’s database provides a rich source of accident data, but conventional analyses of the database yield limited insights to LOC-I. We investigate the causes of 5,726 LOC-I fixed‑wing GA aircraft accidents in the United States in 1999–2008 and 2009–2017 using a state-based modeling approach. The multi-year analysis helps discern changes in causation trends over the last two decades. Our analysis highlights LOC-I causes such as pilot actions and mechanical issues that were not discernible in previous research efforts. The logic rules in the state-based approach help infer missing information from the National Transportation Safety Board (NTSB) accident reports. We inferred that 4.84% (1999–2008) and 7.46% (2009–2017) of LOC-I accidents involved a preflight hazardous aircraft condition. We also inferred that 20.11% (1999–2008) and 19.59% (2009–2017) of LOC-I accidents happened because the aircraft hit an object or terrain. By removing redundant coding and identifying when codes are missing, the state-based approach potentially provides a more consistent way of coding accidents compared to the current coding system.

Résumé :

A 28-year (1982–2009) retrospective investigation was carried out for 3,102 fixed-wing agricultural aircraft involved in the aerial application (Part 137) of pesticides or fertilizers (crop dusting). In total, 64% of the pilots remained uninjured, while 10% of accidents were fatal. This type of aviation is unique as proportionally more accidents occurred during the maneuvering / aerial application and landing phases, involving low-altitude crashes. Collision with poorly visible obstacles in the landscape was involved in 27% of the crashes. These accidents were more likely to involve fatalities, occurred predominantly during maneuvering at the application site, and were often attributed to human error (inappropriate visual lookout and clearance). Recommendations discussed include markings on objects that may improve low-altitude navigation.

Résumé :

In view of public concern about health impairment from accidental radiation exposure, the record of forty years experience in the utilization of nuclear energy was reviewed. All reported exposure incidents producing health effects from external radiation sources and internal radionuclide contamination in the United States and some in other countries have been included. Preparations for the management of such accidents will be considered briefly. The relationship of this actual accident experience to the unresolved problems in management planning and professional and public education for future accidents like that at the Three Mile Island nuclear power station in Middletown, Pennsylvania, March 1979, but with potential associated health impairment, was discussed. The complete paper is published in the Proceedings of the 3rd World Congress for Emergency and Disaster Medicine, organized by the “Club of Mainz” in Rome, Italy, 1983 (see Manni, C and Magalini, S, Springer Publ, Heidelberg, 1984).

Résumé :

General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994 - 2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and injuries attributed to general aviation accidents in the United States, understanding the costs to society is of great importance. This chapter estimates the direct and indirect costs associated with general aviation accidents in the United States. The indirect costs are estimated via the human capital approach in addition to the willingness-to-pay approach. The average annual accident costs attributed to general aviation are found to be $2.32 billion and $3.81 billion (2006 US$) utilizing the human capital approach and willingness-to-pay approach, respectively. These values appear to be fairly robust when subjected to a sensitivity analysis. These costs highlight the large societal benefits from accident and fatality reduction. The final chapter derives a second-best optimal aviation gasoline tax developed from previous general equilibrium frameworks. This optimal tax reflects both the lead pollution and accident externalities, as well as the balance between excise taxes and labor taxes to finance government spending. The calculated optimal tax rate is $4.07 per gallon, which is over 20 times greater than the current tax rate and 5 times greater than the Federal Aviation Administration proposed tax rate. The calculated optimal tax rate is also over 3 times greater than automobile gasoline optimal tax rates calculated by previous studies. The Pigovian component is $1.36, and we observe that the accident externality is taxed more severely than the pollution externality. The largest component of the optimal tax rate is the Ramsey component. At $2.70, the Ramsey component reflects the ability of the government to raise revenue aviation gasoline which is price inelastic. The calculated optimal tax is estimated to reduce lead emissions by over 10 percent and reduce accidents by 20 percent. Although unlikely to be adopted by policy makers, the optimal tax benefits are apparent and it sheds light on the need to reduce these negative externalities via policy changes.

Résumé :

Thesis (Ph.D.)--Boston University
This dissertation probes critical questions about the relationship between the production of cultural meanings, social power, and material objects. By using the public discourse on traffic accidents in the United States as a historical case study, this study investigates in particular the various ways by which social groups respond to unintended technological consequences and dangers within definitional processes of collectively constructing a social problem. The textual-thematic analysis draws largely upon theories from social problems literature and science & technology studies, as it looks at a number of salient historical claimsmakers, sites of discourse production, and cultural vehicles of meaning making. Specifically, the contributions of the private insurance industry, safety establishment, consumer market, automobile clubs, and printed media are closely dissected to flesh out the contours and content of the accident problem's construction and development through time. In line with a contextual constructivist approach to social problems analysis, the research has observed the emergence, evolution, and eventual waning of the accident issue along several structural anchors that provide possible explanations for some of these dynamics. To a great extent, the traffic accident problem has gradually 'disappeared' in America throughout the twentieth century - a disappearance that is not physical but conceptual. Specifically, it means that the troubling social condition is defined as something to live with, a necessary evil of which there seems to be limited ability or desire to substantially affect or eradicate. The sociological concept I employ to name this particular trajectory towards problem attenuation is normalization. Applied to the case analyzed here, the findings offer a way to understand the processes by which traffic accidents become nom1alized in America as an acquiescent price to pay for the benefits of the automobile. Theoretically, these conclusions have laid the groundwork for producing a hypothetical model of social problems normalization. The model highlights the role played by several cultural devices of claimsmaking in affecting issue attenuation or 'disappearance.' When the problem is constructed through highly technicizing, commensurating, commodifying, and socially controlling modalities of sense making, the likelihood of its normalization and eventual floundering increases.

Résumé :

After an unfortunate series of accidents in the mid 1930’s the Air Transport Association (ATA) lobbied Congress for regulation of the industry. The ATA claimed that unfair competition was endangering the public safety. The Civil Aeronautics Act of 1938 created the Civil Aeronautics Board (CAB) and gave the CAB the authority to regulate the industry. During the regulation era airline ridership increased and safety improved. During the regulation period, opportunity for comparing the safety record of the regulated industry with the record of the unregulated portions of the industry was limited. The few attempts made rendered inconclusive results. During a period of high inflation and high interest rates in the 1970’s interest in deregulating the airlines arose. With passage of the Airline Deregulation Act of 1978, interest in the effects of regulation on airline safety was renewed. More than a decade has passed since deregulation. The industry has continued to improve its safety record during the deregulation period. The question remains: "How has deregulation affected airline safety?" In this study records of airline accidents and incidents investigated by the National Transportation Safety Board are examined. The occurrences are divided into those with causes that are under the airlines control and those that are not under their control. Those under the airlines control are regressed against time and a dummy variable for deregulation. The possible effects of airline profitability on the results are also explored. The results indicate that deregulation had an adverse effect on airline safety. The effects of alternative formulations are also examined. The effect though statistically significant is small. It does not suggest the need to return to a regulated airline industry. But, it does suggest the need for additional research into the connection between airline safety and competition.

Résumé :

The purpose of this study was to locate, examine, classify and analyze lawsuits based on student injuries due to alleged negligence in public school physical education and athletic programs in the United States during the period of 1980 to 1984. A preliminary investigation of the American Digest System revealed appropriate case citations for this study. Each citation was used to locate the lawsuit in the respective regional reporter of the National Reporter System. Each case was thoroughly studied and reported. The analysis of cases revealed that 21 sports-injury lawsuits in physical education and 24 in athletic programs occurred during this time period. Twenty-one lawsuits involving playground or other injuries were also examined for related information. Each case was classified and discussed according to the primary area of alleged negligence. These primary areas included standard of care, adequacy of instruction, adequacy of supervision, adequacy and safety of facilities and equipment, adequacy and safety of protective equipment and other related areas. Of all of the cases discussed in this study, 23 were ruled in favor of the plaintiff, with 15 held for the defendant. The doctrine of governmental immunity was upheld in 28 of the cases. The legal liability of school districts and boards of education and that of physical education teachers and athletic coaches was determined from this analysis. The status of governmental immunity and current trends of the court decisions were also discussed. The study concluded with implications for the field and recommendations for further study.

Résumé :

In conformity with the principles laid down in article 26 of the Chicago Convention and its Annex 13 concerning technical aircraft accident investigations, the United States and France respectively set up and developed their own investigation Boards, the NTSB and the BEA, which may be different by their organization and functioning but both aim at the same objective: the promotion of Air Safety.
To fulfil their complex mission in the best possible conditions and despite eventual pecuniary constraints, the pressure of the media, or the occasional tensions which may arise in case of concomitance with other investigations, the NTSB and the BEA rely on the renowned professionalism and high technical skills of their employees as well as on the participation in the investigation of members of the aeronautical industry who bring their expertise and contribute to the improvement of air safety.

Résumé :

Abstract Injuries stemming from automobile accidents are the most numerous and costly of all personal injuries in North America. They are also one of the most fertile areas of current experience and debate regarding the role of the tort system and its alternatives. In 1989, roughly 5 million Americans experienced auto-related injuries, 47,000 of which were fatal.1 In Canada, more than 200,000 people were injured in motor vehicle accidents in 1985 and more than 6,000 died.2 To put these figures in perspective, between 1945 and 1985 more Canadians died as a result of automobile accidents (168,319) than the combined total of Canadians killed in both world wars (102,703)..The costs of these injuries are enormous. In 1985, the economic costs (medical expenses, wage losses, and other out-of-pocket expenses) of automobile injuries in the United States are estimated to have totalled $50 billion, .and another estimate assessed the 1986 costs at $74.2 billion.5 Further, despite steady decreases in the annual number of traffic fatalities in Canada and the United States since the mid-1970s, injury insurance costs have risen sharply during this period, increasing by about 140% in the United States from 1977 to 1987..Largely in response to liability premium increases, governments and policy makers have shown renewed interest in no-fault alternatives to tort law in this area, after a long period of inaction following the initial enactment of no-fault schemes in 16 U.S. states and the province of Quebec between 1971 and 1977. Ontario adopted a no-fault regime in 1989, and existing approaches to preventing and compensating automobile injuries have come under increasing scrutiny as policy makers seek empirical evidence to guide current policy choices. This chapter reviews this evidence on the tort system and on alternative methods of injury prevention and compensation.

Résumé :

Abstract The need for crisis intervention in accidents is frequently underestimated. The number of people killed in traffic accidents every year is daunting: 42,682 in 2006. Encouragingly, data from the National Health, Transportation, and Safety Administration (NHTSA) indicates that the number of traffic fatalities in the United States declined 2% during 2005–2006, or 1.42 fatalities per 1 million miles driven—the lowest number in American history (National Health Transportation and Safety Administration, 2006). However, the number of people injured in other types of accidents has been rising. According to the Centers for Disease Control (CDC), there were approximately 108 million emergency room visits in the United States between 2004 and 2005. Many of these were the result of accidents, including work-related falls, traffic, crimes, and accidental drug/medication reactions (American College of Emergency Physicians [ACEP], 2008).

Résumé :

Abstract This chapter covers the development of casualty insurance and workers’ compensation. An early form of casualty insurance was travel insurance, which became available in the United States in the 1860s. The coverage soon broadened to cover all accidents and injuries causing disability. Accident insurers began to sell employers’ liability coverage as workplace injuries increased. Problems with this market led to the development of workers’ compensation in the early twentieth century. Workers’ compensation laws rolled out in different forms across states over nearly four decades. Progressive reformers hoped that workers’ compensation would be the basis for a broader set of social insurance programs, yet in the postwar period the country embraced a probusiness type of “Americanism” in which state insurance was viewed as a stepping stone to socialism. The provision of voluntary benefits to employees—welfare capitalism—began to emerge as the uniquely American solution to the unmet needs of workers.

Résumé :

This chapter focuses on child mortality. Child mortality is declining worldwide, according to a half-century’s worth of data from the Human Mortality Database and the World Health Organization (WHO). Since the 1980s, however, the United States has had higher rates of mortality for kids aged 0 to 19, compared to other wealthy Organization for Economic Cooperation and Development (OECD) nations. In 2013, the United Nations Children’s Fund (UNICEF) ranked the health and safety of children in the United States 25th out of 29 developed countries. Meanwhile, according to a 2018 Health Affairs study, from 2001 to 2010, the risk of death in the United States compared to peer nations was 76% greater for infants and 57% greater for children and youth age 1 to 19. In that same time frame, American teens age 15 to 19 were 82 times likelier to die from gun-related homicide. As such, US policymakers need to focus on preventing child mortality by preventing the largest contributors to this challenge: perinatal deaths, car accidents, and firearm assaults.

Résumé :

Abstract In many parts of the world, mobility has vastly improved over the past century. Increasing mobility combined with urbanization and (in some cases) rapid population growth is creating undesirable negative impacts on economies and individual quality of life. In 1995, commuters in the United States spent more than 2 billion hours in traffic jams, generating US$100 billion in lost productivity (USDOT 1998a). In 1996, 41,907 people were killed and another 3.5 million were injured in the United States due to automobile accidents (USDOT 1999a). In Japan, over 10,000 people die in traffic accidents each year, about 5.6 billion person hours were spent in traffic congestion.

Résumé :

The accident at the three reactor units at Fukushima Daiichi showed weaknesses in the plant coping capability for beyond design basis accidents caused by extreme external events. The weaknesses included plant design features, accident management procedures and guidance, and offsite emergency response. As a result, significant changes to plant coping capability have been made to light water reactors worldwide to enhance the coping capabilities for beyond design basis accidents. However, the response in the United States has been significantly different from that in Europe in a number of ways. In the United States, the regulator and the industry convened separate expert panels to review the Fukushima accident and make recommendations for enhancements. On the regulatory side, a series of three Orders were issued and that required the implementation of certain enhancements (Mitigation strategies, hardened vents for certain BWRs, spent fuel pool level indication) to ensure adequate protection for the health and safety of the public. Other enhancements were subject to the “Backfit Rule” which requires that changes to regulatory requirements be shown to be cost beneficial using accepted methodologies. Simultaneously, the industry took independent steps to develop a diverse and flexible coping strategies (known as FLEX) and other enhancements. The focus in the United States was clearly on enhancements to guarantee continued core, containment and spent fuel pool cooling in the event of beyond design basis accidents, particularly those resulting from extreme external events. In Europe, the regulatory agencies ordered the development and completion of “Stress Tests” for each reactor site. These Stress Tests were focused on identifying the capability of the plant and its staff to respond to increasingly severe external events. The Stress Tests not only examined the ability to maintain core, containment and spent fuel pool cooling but also the ability to mitigate the consequences of accidents that progress to core damage (i.e., a severe accident). Regulatory requirements were then issued by the national regulators that addressed the weaknesses identified from the Stress Tests. While many of the enhancements to the plant coping capability were similar to those in the United States, significant hardware enhancements were also required to reduce the consequences of core damage accidents including hydrogen control and containment filtered venting. Finally, most European regulators also include severe accident management guidance (SAMG) as a regulatory requirement. In the United States, SAMG will be maintained as a voluntary industry commitment that is subject to regulatory oversight review.

Résumé :

Travel by rail in the United States is one of the safest modes of transportation available. On the rare occasion that major accidents do occur, they represent an opportunity for railroads to learn what has happened and what needs to be done to prevent reoccurrence. This paper provides several, detailed case studies of noteworthy passenger and rail transit accidents that have occurred in the United States, from the 1960s to the present. It discusses the outcome of these accidents, including changes that were implemented due to lessons learned. It also discusses unique and/or noteworthy aspects of each accident.

Résumé :

Railroads contribute to the national economy by carrying over 40% of intercity freight ton-miles in the United States. Train accidents cause damage to infrastructure and rolling stock, disrupt operations, and have the potential to result in casualties and damage the environment. A clear understanding and analysis of accident risk based on historical accidents can support the development and prioritization of effective accident prevention strategies. While extensive previous studies have focused on the safety risks associated with a variety of train operation conditions, much less work has been undertaken to evaluate train risk and safety under restricted speeds. As defined in 49 CFR 236 Subpart G, restricted speed is a speed that permits stopping within one-half the range of vision, but not exceeding 20 miles per hour. Nevertheless, some severe accidents at restricted speeds occurred in the last few years and are also highlighted in both NTSB and FRA reports. In this paper, we develop a quantitative analysis of restricted-speed accidents occurring between 2000 and 2016, based on the data from the U.S. Federal Railroad Administration. While overall accident rates have been proven to decline in prior studies, the preliminary results show that the rate of train accidents under restricted speeds fluctuates in the study period, without a significant increasing or decreasing trend. Furthermore, the distribution of restricted-speed accident severity, accident risk, and other pertinent characteristics are covered in this study.

Résumé :

Abstract Two hundred sixty-nine regulated pipeline system accidents caused fatalities and/or injuries in the United States between 2010 and 2018, resulting in 106 fatalities and 599 injuries requiring hospitalization. About 84% of these serious accidents occurred on gas distribution systems, which primarily transport natural gas. This study adapts probabilistic risk assessment (PRA) methods which are used predominantly in the space and nuclear industries to gas distribution systems in the U.S. Nationwide system and accident data are used to evaluate natural gas distribution system risks, estimate how many additional resources the public would be willing to dedicate to reduce or eliminate these risks, and determine which improvement areas warrant further evaluation. Recommendations regarding the overall PRA-based framework, as well as the scope, quality, and level of detail of the underlying data, are provided.

Résumé :

Railways have a substantial contribution to the economy of the United States. However, a train accident can result in casualties and extensive damages to infrastructure and the environment. Most of the prior research focused on derailments or grade-crossing accidents rather than the study of train collisions. The Federal Railroad Administration (FRA) identifies over 300 causes for all types of accidents, among which we aim to recognize the major factors that cause train collisions. Evaluating how collision frequency and severity vary with the accident cause is the key part of this research, in order to identify, evaluate and mitigate transportation risk. This paper presents a statistical analysis of passenger and freight train collisions in the United States from 2001 to 2015 to statistically analyze train collision frequency, severity, accident cause, and safety risk. The analysis finds that human errors and signal failures are among the most common causes of train collisions in U.S. in the 15-year study period. There is a significant decline in the overall train collision frequency by year. By observing these trends with respect to train collisions, possible accident prevention strategies could be developed and implemented accordingly.

Résumé :

Train accidents damage infrastructure and rolling stock, disrupt operations, and may result in casualties and environmental damage. While the majority of previous studies focused on the safety risks associated with train derailments or highway-rail grade crossing collisions, much less work has been undertaken to evaluate train collision risk. This paper develops a statistical risk analysis methodology for freight-train collisions in the United States between 2000 and 2014. Negative binomial regression models are developed to estimate the frequency of freight-train collisions as a function of year and traffic volume by accident cause. Train collision severity, measured by the average number of railcars derailed, varied with accident cause. Train collision risk, defined as the product of collision frequency and severity, is predicted for 2015 to 2017, based on the 2000 to 2014 safety trend. The statistical procedures developed in this paper can be adapted to various other types of consequences, such as damage costs or casualties. Ultimately, this paper and its sequent studies aim to provide the railroad industry with data analytic tools to discover useful information from historical accidents so as to make risk-informed safety decisions.

Abstract Nuclear facility safety is crucial to preventing and/or reducing high consequence-low probability accidents and, thus reducing the potential risks posed by United States Department of Energy (DOE) and National Nuclear Security Administration (NNSA) operations at their facilities/activities. DOE/NNSA has the responsibility of developing, issuing, maintaining, and enforcing nuclear safety Directives while fostering a culture that promotes nuclear safety research and development. Lessons learned from past accidents, near misses, and experiments/analyses are also important resources for improving operational nuclear safety in the safety community. This paper first identifies and describes the current Directives in place, including safety review and regulatory process, and safety programs that support implementation of the Directives. This paper also describes a contractor’s approach to identifying and implementing safety using these Directives and lessons-learned in multiple discipline areas of nuclear safety.

Résumé :

Commercial motor vehicle (CMV) safety is a major concern in the United States, including the District of Columbia (DC), where CMVs make up 15% of traffic. This research uses a comprehensive approach, combining statistical analysis and machine learning techniques, to investigate the impact of road pavement conditions on CMV accidents. The study integrates traffic crash data from the Traffic Accident Reporting and Analysis Systems Version 2.0 (TARAS2) database with pavement condition data provided by the District Department of Transportation (DDOT). Data spanning from 2016 to 2020 was collected and analyzed, focusing on CMV routes in DC. The analysis employs binary logistic regression to explore relationships between injury occurrence after a CMV crash and multiple independent variables. Additionally, Artificial Neural Network (ANN) models were developed to classify CMV crash injury severity. Importantly, the inclusion of pavement condition variables (International Roughness Index and Pavement Condition Index) substantially enhanced the accuracy of the logistic regression model, increasing predictability from 0.8% to 41%. The study also demonstrates the potential of Artificial Neural Network models in predicting CMV crash injury severity, achieving an accuracy of 60% and an F-measure of 0.52. These results highlight the importance of considering road pavement conditions in road safety policies and interventions. The study provides valuable insights for policymakers and stakeholders aiming to enhance road safety for CMVs in the District of Columbia and showcases the potential of machine learning techniques in understanding the complex interplay between road conditions and CMV crash occurrences.

Résumé :

Prescription opioid deaths have tripled since 1999, and currently opioid overdose kills 115 Americans per day on average (1). Prior to 2014, prescription opioids have been the primary driver of opioid-related mortality. In recent years, the United States has seen a steady decline in the rate of opioid prescription. At the same time, there has been a significant increase in the number of deaths attributed to non-prescription opioids such as heroin, illicitly manufactured fentanyl, and fentanyl analogues. In 2017, among 70,237 drug overdose deaths nationally, 47,600 (67.8%) involved opioids, with increases across age groups, racial/ethnic groups, and county urbanization levels in multiple states (2). The opioid epidemic is especially profound in Tennessee, which had the 3rd highest opioid prescription rate in the country in 2017 and an opioid-related death rate of 19.3 deaths per 100,000 persons, compared to the national average of 14.6 (3). This retrospective study analyzes autopsy data from West Tennessee Regional Forensic Center (WTRFC) from 2007 to 2017 to gain a better understanding of the effects of the opioid epidemic on West Tennessee and the surrounding areas. Data from opioid-related accidents and suicides were analyzed in order to identify trends in race, age, gender, location, types of opioids, and drug combinations involved in opioid-related deaths.

Résumé :

In 2019, the United States experienced more than 6,500 pedestrian fatalities involving motor vehicles which resulted in a 67% rise in nighttime pedestrian fatalities and only a 10% rise in daytime pedestrian fatalities. In an effort to reduce fatalities, this research developed a pedestrian detection and alert system through the application of a visual camera, infrared camera, and radar sensors combined with machine learning. The research team designed the system concept to achieve a high level of accuracy in pedestrian detection and avoidance during both the day and at night to avoid potentially fatal accidents involving pedestrians crossing a street. The working prototype of pedestrian detection and collision avoidance can be installed in present-day vehicles, with the visible camera used to detect pedestrians during the day and the infrared camera to detect pedestrians primarily during the night as well as at high glare from the sun during the day. The radar sensor is also used to detect the presence of a pedestrian and calculate their range and direction of motion relative to the vehicle. Through data fusion and deep learning, the ability to quickly analyze and classify a pedestrian’s presence at all times in a real-time monitoring system is achieved. The system can also be extended to cyclist and animal detection and avoidance, and could be deployed in an autonomous vehicle to assist in automatic braking systems (ABS).

Résumé :

In an effort to understand and decrease alcohol-impaired driving as a primary collision factor In California, the research team designed an evaluation plan for California Senate Bill 1046 and its focus on ignition interlock devices as a sentence for Driving Under Influence offense. This plan will evaluate whether Senate Bill 1046 affected the Driving Under the Influence crash frequency and severity, and whether sociodemographic and geographic factors influence its effectiveness. This report lays the foundation for the evaluation that will be conducted in 2024. The research team conducted a meta-analysis of the last 12 years of literature and research on ignition interlock programs inside and outside the United States. Based on the findings of this analysis, the recommended evaluation plan of the law revolves around three research questions that focus on the changes in the frequency/severity of DUI-related crashes in California, the impact of the law on recidivism and on interlock installation rates. To respond to these questions, the research team recommends a list of data that should be collected, such as the number of injuries and deaths resulting from alcohol-related motor vehicle accidents, installation rates of ignition interlocks compared to the prior five-year period, the number of individuals who were required to have an ignition interlock device installed who were convicted of an alcohol-related violation, as well as number of lockouts while an interlock is installed. The research team proposed several statistical approaches for the analysis of this data, such as descriptive statistics, time series analysis, analysis of variance, and logistic regression.

Résumé :

Every year, over 60,000 work zone crashes are reported in the United States (FHWA 2016). Such work zone crashes have resulted in over 4,400 fatal and 200,000 non-fatal injuries in the last 5 years (FHWA 2016, BLS 2014). Apart from the physical and emotional trauma, the annual cost of these injuries exceeds $4 million-representing significant wasted resources. To improve work zone safety, this research developed a system architecture for unveiling high-risk behavioral patterns among highway workers, equipment operators, and drivers within dynamic highway work zones. This research implemented the use of a connected virtual environment, which is an immersive hyper-realistic and virtual environment where multiple agents (e.g. workers, drivers, and equipment handlers) control independent simulators but experience an interactive and shared experience. For this project, the team conducted an in-depth analysis of accident investigation, simulated accident scenarios, and tested diverse interventions to prevent high-risk behavior. Overall, the research improved understanding of behavioral patterns that lead to injuries and fatalities of highway workers in order to better protect them in high-risk work environments. As part of making transportation smarter, this project contributes to smart behavioral safety analysis.
