• Abstract:
  Challenging roadway characteristics and high truck percentages create operational and safety concerns on I-80 in WY. High crash frequencies and delays are observed every year. WYDOT is looking for potential mitigation strategies to alleviate those problems. Researchers performed operational and safety analyses along I-80, with a focus on high truck percentages and climbing lanes as the most promising countermeasures for steep vertical grades. The operational analysis was performed through microsimulation and a creation of shock-wave based models, while the safety analysis included descriptive statistics, and cross-sectional and propensity-scores models to estimate the safety effectiveness of climbing lanes.
