RISConnecting Motor Vehicle Crashes with Emergency Medical Services Performance: Spatial Assessment for the Korean Freeway System
Publisher: ASCE
Abstract: The purpose of this study is twofold: to assess prehospital emergency medical service performance and to improve the traffic crash survival rate on Korean freeways. To achieve these objectives, this study utilized a logit ...
Conditional Quantile Analysis for Crash Count Data
Publisher: American Society of Civil Engineers
Abstract: Crashes are important evidence for identifying deficiencies existing in highway systems, but they are random and rare. The investigation of the nature of the problem normally draws on crashes collected over a multiyear ...
Injury Severity of Multivehicle Crash in Rainy Weather
Publisher: American Society of Civil Engineers
Abstract: As part of the Wisconsin road weather safety initiative, the objective of this study was to microscopically assess the factor effects on the severities of multivehicle-involved crashes on high-speed roadways during rainfall ...
Predicting Collision Risk between Trucks and Interstate Overpasses
Publisher: American Society of Civil Engineers
Spatial Analysis of Weather Crash Patterns
Publisher: American Society of Civil Engineers
Abstract: Spatial statistical techniques can be an effective tool for analyzing patterns and autocorrelation in crash data, especially weather-related crashes. Since weather is a geographic phenomenon, it tends to show distinct ...
Combination of Big and Small Data: Empirical Study on the Distribution and Factors of Catering Space Popularity in Nanjing, China
Publisher: American Society of Civil Engineers
Abstract: Using big and small data in urban studies has its advantages and limitations. Combining both data types instead of focusing only on big data is necessary. We took Nanjing as a case study to analyze the popularity of catering ...
Experimental Study on the Mechanical Property Improvement of MICP by Adding Different Polysaccharide Polymers
Publisher: American Society of Civil Engineers
Abstract: The low mechanical properties of microbially induced calcium carbonate precipitation (MICP) significantly hinder the engineering application of this technology. Four polysaccharide polymers, including low-viscosity ...
Hierarchical Bayesian Estimation of Safety Performance Functions for Two-Lane Highways Using Markov Chain Monte Carlo Modeling
Publisher: American Society of Civil Engineers
Abstract: A critical part of any risk assessment is identifying how to represent exposure to the risk involved. Recent research shows that the relationship between crash count and traffic volume is nonlinear; consequently, a simple ...
Interactive Process of Microsimulation and Logistic Regression for Short-Term Work Zone Traffic Diversion
Publisher: American Society of Civil Engineers
Abstract: The rapidly growing number of work zones on national highways is having significant operational impacts due to the temporary loss of capacity. Work zone impact on safety and mobility creates a strong need to alleviate work ...
Handling Imbalanced Data for Real-Time Crash Prediction: Application of Boosting and Sampling Techniques
Publisher: ASCE
Abstract: With a growing number of intelligent transportation system sensors and the networkwide deployment of those across the nation’s roadway facilities, current research and practices should concentrate on more proactive safety ...
