Latent Factors of Severity in Truck-Involved and Non-Truck-Involved Crashes on Freeways
Truck-involved crashes have higher crash severity than non-truck-involved crashes. There have been many studies about the frequency of crashes and the development of severity models, but those studies only analyzed the relationship between observed variables. To identify why more people are injured or killed when trucks are involved in the crash, we must examine to quantify the complex causal r...
متن کاملCrash Frequency Modeling Using Real-Time Environmental and Traffic Data and Unbalanced Panel Data Models
Traffic and environmental conditions (e.g., weather conditions), which frequently change with time, have a significant impact on crash occurrence. Traditional crash frequency models with large temporal scales and aggregated variables are not sufficient to capture the time-varying nature of driving environmental factors, causing significant loss of critical information on crash frequency modelin...
متن کاملDevelopment of Models for Crash Prediction and Collision Estimation- A Case Study for Hyderabad City
Road traffic crash is a cause of unnatural death and occupies fifth position in the world as per WHO records. Road crashes in India are alarming in situation while road safety is professionally lacking and politically missing. Hyderabad city, the capital of newly formed Telangana State occupies sixth position in occurrence of road crashes. An attempt is made to understan...
متن کاملZero Inflated Negative Binomial for Modeling Heavy Vehicle Crash Rate on Indian Rural Highway
Poisson regression and negative binomial regression have been widely used to model the road crashes and to predict crash frequency. Zero inflated models have been shown to be a powerful tool to predict crash frequency when crash data are characterized by preponderance of zero. This paper presents the research work aiming to correlate the road traffic crash rate with road geometry and traffic ch...
متن کاملDifferences in Factors Affecting Various Crash Types with High Numbers of Fatalities and Injuries in China
OBJECTIVES Road traffic crashes that involve very high numbers of fatalities and injuries arouse public concern wherever they occur. In China, there are two categories of such crashes: a crash that results in 10-30 fatalities, 50-100 serious injuries or a total cost of 50-100 million RMB ($US8-16m) is a "serious road traffic crash" (SRTC), while a crash that is even more severe or costly is a "...
