Dynamic Flood Risk Assessment For Transportation Infrastructure In Fresno, Ca, Yushin Ahn, Fayzul Pasha
Mineta Transportation Institute
Urban roadway flooding in flat metropolitan environments often shows up as small areas of standing water rather than large, flowing floods. In low-gradient urban environments, subtle micro-topographic features—such as pavement crowns, curbs, and localized depressions—often control where surface water accumulates following rainfall. Accurately identifying these localized ponding areas is important for roadway flood screening and infrastructure management. This study develops a LiDAR-based depression mapping framework to identify roadway segments susceptible to surface ponding in flat urban environments. High-resolution airborne LiDAR datasets were used to generate detailed elevation maps (down to less than a foot in resolution) from ground-classified point clouds …

Late-Night And Early-Morning Train Scheduling With Non-Traffic Hour Maintenance Window In Urban Rail Transit Systems, Yaochen Ma, Hai Yang, Hai Wang
Research Collection School Of Computing and Information Systems
Regular maintenance during non-traffic hours (NTH) is vital for the resilience of urban rail transit (URT) systems, yet an insufficient NTH maintenance window poses a challenge for URT systems in various cities. For instance, the Hong Kong MTR Corporation has noted that the required NTH maintenance time often exceeds the available window, prompting service adjustments such as earlier late-night closures and/or later early-morning starts. To address this challenge, this study develops an optimal scheduling framework that links late-night and early-morning URT services through the NTH maintenance window requirement to maximize public welfare. A Decoupled Optimization Model (DOM) first derives closed-form …

Congestion Pricing: A Comprehensive Look At International Congestion Pricing Models And Applying Them To The United States, Ian Ertel
Electronic Theses and Dissertations
Urban traffic congestion imposes large costs through wasted time, excess fuel consumption, air pollution, and lost productivity. Although congestion pricing has been recognized as the economically efficient remedy since Pigou and Vickrey, implementation has been rare. This thesis examines the conditions under which congestion pricing succeeds by analyzing three pioneering cases: London, Singapore, and New York City. Across all three, charges reduced traffic volumes and improved speeds within the priced zones. Benefits extended beyond cordon boundaries, with measurable improvements on untolled suburban roads. The distributional effects depended on how revenues were recycled rather than on the charge itself. Political viability, …
