There have been great efforts to develop traffic crash prediction models for various types of facilities. The crash models have played a key role to identify crash hotspots and evaluate …
Objectives This paper aimed to (i) differentiate the effects of contributory factors on crash risks related to different transportation modes, ie, motor vehicle, bicycle and pedestrian;(ii) …
According to crash configuration and pre-crash conditions, traffic crashes are classified into different collision types. Based on the literature, multi-vehicle crashes, such as head-on, rear …

This study aims at contributing to the literature on pedestrian and bicyclist safety by building on the conventional count regression models to explore exogenous factors affecting …
BACKGROUND: Traditional crash prediction models, such as generalized linear regression model, are incapable of taking into account multilevel data structure. Therefore they suffer …
This study attempts to explore the viability of dual-state models (ie, zero-inflated and hurdle models) for traffic analysis zones (TAZs) based pedestrian and bicycle crash frequency …
Introduction Macro-level traffic safety analysis has been undertaken at different spatial configurations. However, clear guidelines for the appropriate zonal system selection for …
