Abstract

"Transportation infrastructure is a critical foundation for economic productivity, yet agencies still face challenges in translating the expanding transportation datasets into defensible, phase-specific risk-governance tools. This dissertation addresses this gap by developing analytical and empirical, data-driven approaches to support risk governance across the transportation project lifecycle. Module 1 uses a panel model with bid-letting data to examine how out-of-state contractor participation affects pre-award competition and to derive entry-governance rules. Module 2 analyzes nonfatal injury data through iterative multiple linear regression and fatality data through association-rule change mining to identify multi-factor safety-risk configurations and develop adaptive safety-governance provisions. Module 3 develops a game-theoretic model calibrated with historical price-index data to assess whether price adjustment clauses achieve equitable risk sharing. Module 4 uses expert-elicited survey data and structural equation modeling to validate the factors affecting smart-contract feasibility and translate them into an implementation roadmap. Module 5 applies an ANOVA/MANOVA screening pipeline to Emergency Relief Fund allocation records to identify statistically distinctive highway disaster case studies that can inform resilience governance. Collectively, the modules replace ad hoc decision-making with an integrated analytical–empirical toolkit that translates lifecycle evidence into actionable risk-governance policy. These include procurement rules that support competitive entry, safety provisions targeting key injury and fatality configurations, contract calibration rules to manage price volatility, a validated roadmap for smart-contract integration, and reproducible logic for selecting disaster case studies"-- Abstract, p. iii
