Crashes at highway rail grade crossings (HRGCs) are often involved with fatalities due to the momentum of a train. This study collected nine years (2010–2018) of fatal HRGC crashes from the Fatality Analysis Reporting System (FARS) to perform the a

The use of statistical models for analyzing traffic safety (crash) data has been well-established. However, time series techniques have traditionally been underrepresented in the corresponding literature, due to challenges in data collection, along w

This study aims to rank high crash risk areas and measure the impacts of accessibility and other spatial and socio-economic factors on county-level crash severities while controlling for spatial and temporal unobserved effects. Among other insights,

Intersection crashes are a safety concern for many transportation agencies, and crashes related to red light running (RLR) vehicles are of particular interest. Many camera-based RLR detection systems are controversial with the public, and there is re

In updating road-user fees, highway agencies are motivated by the twin objectives of equity and efficiency. The concepts of marginal pavement consumption cost (MPCC) and the fourth-power law have been used in past research in a bid to establish effic

The average delay is a commonly used measure for characterizing the performance of signalized intersections. Current methods for estimating the average delay rely on models that are based on traffic volumes and green times. In practice, the developme
