  2. Operational policies and fee structures for vehicle use on highways. Dr. Labi's work in this area was requested by the Indiana House of Representatives and has spawned changes in state law regarding overweight truck operations and highway cost allocation and finance.
  3. Development of tools based constrained multiple-objective optimization of infrastructure resources and investment tradeoffs. This work includes multi-objective optimization for project selection in network-level management of bridges, pavements, safety, and other highway assets, decision support system for optimal scheduling of highway maintenance, and safety improvement programming for rural two-lane highways using constrained optimization at a system-of-systems level.
  4. Derivation of theoretical constructs for assessments of infrastructure renewal effectiveness. Developed theoretical constructs and statistics/econometrics-based methodologies to assess the effectiveness, in terms of the increased longevity or enhanced condition, of emerging classes of treatments applied to highway assets (pavements and bridges).
  5. Development of frameworks for region-wide investment decision-making and impact evaluation. Incorporation of safety in network-level transportation planning; linking interstate pavement preservation investment to performance; accessibility and connectivity assessments; efficiency measurement of highway bridge replacement and rehabilitation and of the operational performance of public transportation agencies.
  6. Project management and cost estimation in highway infrastructure development. infrastructure user cost estimation; asset preservation or replacement cost functions; planning-phase cost estimation; change orders in highway construction; and time and cost overruns in construction contracts.
