Crash data analysis: collective vs. individual crash level approach.
INTRODUCTION Traffic safety literature has traditionally focused on identification of location profiles where "more crashes are likely to occur" over a period of time. The analysis involves estimation of crash frequency and/or rate (i.e., frequency normalized based on some measure of exposure) with geometric design features (e.g., number of lanes) and traffic characteristics (e.g., Average Annu...
متن کاملCARE: An Automobile Crash Data Analysis Tool
T he University of Alabama, with National Highway Transportation Safety Administration funding for traffic accident problem identification and evaluation, has developed the Critical Analysis Reporting Environment software system to analyze automobile crash data. CARE’s developers designed it for use by transportation safety engineers and policymakers, rather than trained statisticians. To date,...
متن کاملHeavy Vehicle Crash Rate Analysis: a Comparison of Heterogeneity Methods Using Idaho Crash Data
Studies investigating crash rates by roadway classification are few and far between and even more so if extended to focus on heavy vehicles. This study explores and compares two advanced econometric methods, random-parameter Tobit regression and latent class Tobit regression, to determine contributing factors for heavy vehicle crashes per million-vehicle-miles-traveled while accounting for the ...
متن کاملUnderstanding traffic crash under-reporting: Linking police and medical records to individual and crash characteristics.
OBJECTIVE This study aligns to the body of research dedicated to estimating the underreporting of road crash injuries and adds the perspective of understanding individual and crash factors contributing to the decision to report a crash to the police, the hospital, or both. METHOD This study focuses on road crash injuries that occurred in the province of Funen, Denmark, between 2003 and 2007 a...
متن کاملData Mining on Crash Simulation Data
The work presented in this paper is part of the cooperative research project AUTO–OPT carried out by twelve partners from the automotive industries. One major work package concerns the application of data mining methods in the area of automotive design. Suitable methods for data preparation and data analysis are developed. The objective of the work is the re–use of data stored in the crash–simu...
