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 کاملVehicular crash data used to rank intersections by injury crash frequency and severity
This article contains data on research conducted in "A double standard model for allocating limited emergency medical service vehicle resources ensuring service reliability" (Liu et al., 2016) [1]. The crash counts were sorted out from comprehensive crash records of over one thousand major signalized intersections in the city of Chicago from 2004 to 2010. For each intersection, vehicular crashe...
متن کاملWindows XP Kernel Crash Analysis
PC users have started viewing crashes as a fact of life rather than a problem. To improve operating system dependability, systems designers and programmers must analyze and understand failure data. In this paper, we analyze Windows XP kernel crash data collected from a population of volunteers who contribute to the Berkeley Open Infrastructure for Network Computing (BOINC) project. We found tha...
متن کاملSnowstorm Event-based Crash Analysis
This study investigated the snowstorm impact on Wisconsin state highway system and assessed the winter maintenance effort in improving highway safety from a macroscopic perspective. Though the inverse relationship between the de-icing material consumption and the crash counts during the snowstorms is not reflected in the analysis, it implies that causes of snowstorm crashes are multifold. The f...
متن کاملCrash Frequency Analysis Using Hurdle Models with Random Effects Considering Short-Term Panel Data
Random effect panel data hurdle models are established to research the daily crash frequency on a mountainous section of highway I-70 in Colorado. Road Weather Information System (RWIS) real-time traffic and weather and road surface conditions are merged into the models incorporating road characteristics. The random effect hurdle negative binomial (REHNB) model is developed to study the daily c...
