This paper presents a before-after crash, injury and traffic study of constructing bicycle tracks and marking bicycle lanes in Copenhagen, Denmark. Corrections factors for changes in traffic volumes and crash / injury trends are included using a general comparison group in this non-experimental observational study. Analysis of long-term crash trends points towards no significant abnormal crash ...

ITE JOURNAL / SEPTEMBER 1998 DESPITE PROGRESS IN REDUCing motor vehicle crash deaths and injuries in the United States, sharp horizontal curves situated on narrow twolane highways—a common roadway design feature—pose a significant safety threat. According to data published by the National Highway Traffic Safety Administration, nearly 80 percent of all fatal crashes in the United States occur on...

375 Alcohol-impaired driving is a major public health problem in the United States. Traffic crashes involving alcohol killed more than 16,000 people in 1997 alone (National Highway Traffic Safety Administration [NHTSA] 1998b) and injure a million more each year (Blincoe 1996). Fatal traffic crashes, the leading cause of death for those aged 1 through 24, involve alcohol 4 times out of 10 (NHTSA...

INTRODUCTION In spite of recent advances in traffic surveillance technology and ever-growing concern over traffic safety, there have been very few research efforts establishing links between real-time traffic flow parameters and crash occurrence. This study aims at identifying patterns in the freeway loop detector data that potentially precede traffic crashes. METHOD The proposed solution ess...

Decision-makers have long speculated that building separate roads for trucks and passenger cars, or at least separating them on their own lanes would accomplish two major objectives: 1) they would make the roadways safer for passenger cars, and 2) roadways designed specifically for a select class of vehicles rather than for all vehicles might represent overall savings in construction costs. Thi...

background road traffic injuries are among the leading causes of death in the world and iran. objectives the aim of this study was to assess the role of age, sex, education, and time of accident on human casualties and mortalities of road crashes in iran. materials and methods this study was based on data gathered by iranian police department from the records of road crashes from april 4, 2008 ...

Increasing evidence suggests that neighborhood-based measures of socioeconomic status are correlated with traffic injury. The main objective of this study is to determine the differences in associations between predictive variables and injury crashes (i.e. including injury and fatal crashes). To this end, crash data, socio-demographic, socioeconomic characteristics and road network variables ar...
