Investigation of Effects of Inherent Variation and Spatiotemporal Dependency on Urban Travel-Speed Prediction
(ASCE, 2020)Urban traffic prediction is a challenging task due to the complexity of urban networks. Many studies have been conducted to improve the prediction accuracy, but the limitation still remains that their accuracy varies with ... -
Right-Hook Crash Scenario: Effects of Environmental Factors on Driver’s Visual Attention and Crash Risk
(ASCE, 2020)A right-hook (RH) crash is a common type of bicycle–motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection in right-hand driving countries. Despite the frequency and ... -
Base Train Equivalents for Multiple Train Types Based on Delay-Based Capacity Analysis
(ASCE, 2020)Different types of trains may have substantially dissimilar characteristics, which result in various capacity effects. The concept of base train equivalent (BTE) has been previously proposed to standardize different train ... -
Pedestrian Crossing Warrants for Urban Midblock Crossings under Mixed-Traffic Environment
