Geometric effect analysis of highway-rail grade crossing safety performance.

•Survival analysis in highway rail grade crossing safety analysis is introduced.•Crossing geometric factors, traffic exposure, and highway/railway characteristics are found significant contributors.•Effects on crash frequency and crash severity are researched.•Geometric factors’ long-term effects on cumulative probability of crash severity and occurrence over 30 years is evaluated.•Crossings with three main tracks contribute the highest long-term crash probability.
