Deadlier Road Accidents? Traffic Safety Regulations And Heterogeneous Motorists’ Behavior, Christine Ho, Madhav S. Aney

Research Collection School Of Economics

In 2003, China enacted the Road Traffic Safety Law in an attempt to promote traffic safety.We employ a difference-in-differences strategy on province level data, where fire accidentsare used as a control group for road accidents, to estimate the effects of the law on road accidents and casualties. Our findings suggest that while the law was successful in decreasing thenumber of accidents and casualties, the ratio of deaths to accidents and injuries to accidentsincreased. Exploring the potential channels, we find no evidence that “hit-and-kill” incentives,that is, incentives for motorists to kill the pedestrians that they hit due to China’s peculiar personal …

Analysis Of The Frequency And Severity Of Rear-End Crashes In Work Zones, Yi Qi, Raghavan Srinivasan, Hualiang Teng, Robert Baker

Yi Qi

OBJECTIVE: The objective of this study was to identify the factors that influence the frequency and severity of rear-end crashes in work zones because rear-end crashes represent a significant proportion of crashes that occur in work zones. METHODS: Truncated count data models were developed to identify influencing factors on the frequency of rear-end crashes in work zones and ordered probit models were developed to evaluate influencing factors on the severity of rear-end crashes in work zones. RESULTS: Most of the variables identified in this study for these 2 models were significant at the 95 percent level. The statistics for models …

Simultaneous Equation Modeling For Crash Rate Of Freeway Segments, Anthony Ramos

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2010, the total number of reported traffic crashes in the state of Nevada was 51,664 of which 235 (0.6%) resulted in one or more deaths (Nevada Department of Transportation, 2012). The state's "Zero Fatalities" traffic safety campaign aims to reduce the rate even further. Out of the total number of crashes, Clark County (includes Las Vegas) accounted for 78.89%. This study examines safety improvement by developing advanced crash prediction models. The system of crash prediction equations consider geometric conditions and traffic volume using simultaneous equation modeling (SEM). The models are based on geometric characteristics and traffic volume data collected …

Investigation Of Crashes And Identifying The Best Practices For Setting Up Speed Zones In Towns Along Rural Highways In Nevada, Krishna Prasad Shrestha

Joseph Shrestha

In 2010, 51,664 crashes occurred in Nevada. Only about 9% of those crashes occurred in rural areas of the state. However, if only fatal crashes are considered, 41% of those fatal crashes occurred in rural areas. Generally, speed zones are provided in towns along rural highways to reduce speed-related crashes. However, a guideline is necessary for a consistent procedure to setup speed zones throughout the state. The main objectives of this study are to determine factors associated with crashes and to identify the best practices for setting up speed zones in towns along rural highways.

Driving Forces: Factors Affecting Police Officer Injuries In Motor Vehicle Incidents In The United States, Carol Servino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traffic-related incidents were the leading cause of fatal injuries to officers in 14 of 15 years between 1997 and 2012. Vehicle crashes occur at the individual officer level, but chiefs are responsible for agency performance, creating and implementing police policy, and developing organizational culture. This quantitative survey research study draws from organizational culture theory and asks chiefs in state, county, and city police organizations what they believe are salient factors in crashes causing injuries and death to police officers in the United States. Independent variables include safety belt laws, written driving policies (including communication technology commonly used in police vehicles), …

Police Injury Crashes And The Intersections Of Policy, Technology, And Culture, Carol Servino

Graduate Research Symposium (GCUA) (2010 - 2017)

Motor vehicle crashes caused the majority fatalities to police officers in the U. S. for more than a decade, yet little is known about factors contributing to injury crashes. This research project required original data collection. A national survey of police chiefs in state, county, and local agencies of all sizes was conducted online in June and July, 2012. Questions focused on various driving policies and practices, including those related to communication technology commonly used in police patrol vehicles. Other questions included hypothetical situations to explore the culture of driving safety in individual police organizations. The majority of chiefs clearly …

Hispanic Ethnicity, Male Gender And Age Predict Restraint Use And Hospital Resource Utilization In Pediatric Trauma, Deborah A. Kuhls, Lynne Fullerton-Gleason, Virginia A. Landry, Julie A. Rabeau, Elizabeth Snavely, John J. Fildes

Journal of Health Disparities Research and Practice

Child restraint reduces the severity of injuries in motor vehicle crashes. Racial/ethnic groups appear to have differing restraint use rates. The objective of this study was to identify restraint use differences between ethnic and other demographic subgroups of pediatric trauma patients. Prospective data were analyzed for 1072 consecutive pediatric patients aged 19 or less who were involved in motor vehicle crashes and brought to our Trauma Center over a 42 month period. The demographic breakdown of this study cohort was 55.3% male, 21.4% Hispanic, 9.7% African American, 64.5% Caucasian, 2.2% Asian and 2.2% other. The highest rates of restraint use …

Broken Windows, Police, &Traffic Safety, Carol Servino

Graduate Research Symposium (GCUA) (2010 - 2017)

Abstract This research explores application of the “broken windows” theory of public disorder and urban decline to the pattern and problem of police officer fatalities in motor vehicle crashes. It contextualizes the influential theory into a 45-year timeline of significant events related to legislative efforts and traffic safety behavioral safety programs in the United States. It finds one police agency that reported fewer crimes and fewer crashes after implementing a community-wide Safe Streets program designed around “broken windows” theory in 1997. It pays particular attention to states with the highest percentages of law enforcement officer fatalities in motor vehicle crashes, …

Statistical Analysis Of Fatalities Due To Vehicle Accidents In Las Vegas, Nv, Annabelle Marie Mathis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this thesis is to investigate factors that affect the odds of having a fatality in a vehicle collision. We will be looking at characteristics of the driver that caused the accident (age, gender, behavior, actions, influences, and seat belt worn), the characteristics of the vehicle the driver drove (type of vehicle, and air bag deployment), the characteristics of the environment in which the accident occurred (weather, road condition, lighting, time of day, the day of the week, and month of the year), the characteristics of the crash (direction of accident and how many vehicles were involved), and …

Injury In Nevada, Michelle Chino, Jonathon Lavalley, Darlene R. Haff, Deborah A. Harris, Andrea R. Rivers

Public Health Faculty Publications

Injury is a major threat to health and safety. In a typical day in the US, 400 people will die as the result of an injury, 7,500 will be hospitalized due to an injury, and more than 150,000 will suffer an injury severe enough to restrict activities and seek medical attention. Many of these deaths, hospitalizations, and disabling events will be the result of motor vehicle crashes. Others will result from vio­lence, falls, drowning, and poisoning – all of which are considered injuries.

The costs of injury are high. In the United States, the cost of injuries is estimated to …

Validation Of Waimss Incident Duration Estimation Model, Wei Wu, Pushkin Kachroo, Kaan Ozbay

Electrical & Computer Engineering Faculty Research

This paper presents an effort to validate the traffic incident duration estimation model of WAIMSS (wide area incident management support system). Duration estimation model of WAIMSS predicts the incident duration based on an estimation tree which was calibrated using incident data collected in Northern Virginia. Due to the limited sample size, a full scale test of the distribution, mean and variance of incident duration was performed only for the root node of the estimation tree, white only mean tests were executed at all other nodes whenever a data subset was available. Further studies were also conducted on the model error …

Wide-Area Incident Management System On The Internet, Kaan Ozbay, Pushkin Kachroo

Electrical & Computer Engineering Faculty Research

The incident management process consists of four sequential steps-incident detection, response, clearance and recovery. Each of these components comprises of a number of operations and coordinated decision-making between the agencies involved. The provision of computer based support tools for the personnel involved will help develop appropriate strategies and increase efficiency and expediency. Existing systems are developed on various traditional computing platforms. However, with the advent of World Wide Web and Internet based programming tools such as Java, it is now possible to develop platform independent decision support tools for the incident management agencies. Any agency will be able to use …
