To investigate pedestrian exposure when only pedestrian-crash data are available, the quasi-induced exposure method is used to identify the factors that contributed to pedestrian-vehicle crashes in Las Vegas from 2004 to 2008. The results show that overall crash severity, light conditions and weather conditions are potentially risky factors in pedestrian crashes, and the time of day or day of t...
We designed this questionnaire-based study to determine the risk of auto crashes among Alzheimer's disease (AD) patients who continued to drive after the onset of AD, compared with normal age-matched control subjects and other drivers' statistical records. While ultimately all AD patients will become incapable of driving, it is not known whether, under current licensing regulations and self-imp...
OBJECTIVE The initial months of licensure are especially hazardous for teenagers. Factors leading to crashes of novice 16-year-old drivers were identified. METHOD Sixteen year-olds in Connecticut who were involved in nonfatal crashes during the first 8 months of licensure were interviewed, and police crash reports were examined. Crash types and contributing factors were identified. RESULTS ...
OBJECTIVES Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: 1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and...
Motorcycles are popular in Asian countries including Sri Lanka and it is becoming an important part of transportation in the country. Despite its popularity, little research has been conducted to study the impact of motorcycles on road safety in Sri Lanka. The objective of this study was to investigate the risk factors of crashes involving motorcycles. Data was obtained from Police crash record...
Bicycling crashes on streetcar (tram) or train tracks: mixed methods to identify prevention measures
BACKGROUND Streetcar or train tracks in urban areas are difficult for bicyclists to negotiate and are a cause of crashes and injuries. This study used mixed methods to identify measures to prevent such crashes, by examining track-related crashes that resulted in injuries to cyclists, and obtaining information from the local transit agency and bike shops. METHODS We compared personal, trip, an...
In this short note we discuss recent attempts to describe pre-crash market dynamics with analogies from theory of critical phenomena. Stochastic dynamics is a commonly used approach to describe the time evolution of financial markets. The large number of agents, their complex mutual influence and obscure decision making all of these leave the probabilistic picture as the only viable way to desc...
In India, 486,476 crashes are reported and 137,572 fatalities during 2013. Major share of crashes (28.8% of total crashes) are on National Highways. Considering high importance of NHs in overall road network with respect to its connectivity to state capitals and business centres, and cater to high share of traffic (40%), there is an urgent need to investigate factors contributing to crashes on ...
Demographic and alcohol-related data collected from eight-grade students (age 13 years) were used in logistic regression to predict subsequent first-year driving crashes and offenses (age 17 years). For young men's crashes and offenses, good-fitting models used living situation (both parents or not), parents' attitude about teen drinking (negative or neutral), and the interaction term. Young me...
PROBLEM Automobile crashes remain a prominent cause of death and injury for teenagers in the United States. While it is generally agreed that graduated drivers licensing (GDL) influences crash rates, it is unclear which components have the strongest effect on any specific types of crashes. METHOD We analyze the relative effect of different stages of GDL on teenage fatal and injury crash risk ...
