The project would generally involve a panel of state DOTs and EPA with a mandate to develop sample project-level studies (modeling and documentation) for particulate (and carbon monoxide and NO2…
NESHAP applies to demolition and “renovation” (modification); requires prior inspection for presence of asbestos and remediation prior to demolition/renovation if possible; what’s the best way and time/place to do that? Is it necessary…
EPA’s 1-hour NO2 standard is low enough to potentially cause problems, and they require near-road monitoring to determine attainment. What are the best methods for modeling roadway and rail (non-electric) NO2 microscale impacts?…
If a project has known lead-contaminated soils, what are the best management practices for construction and maintenance activities in those areas for purposes of both worker safety and protection of nearby areas?…
Problem Evidence suggests that there are synergies between transit, land use, and pricing strategies that enhance the greenhouse gas (GHG) reduction effect of each when implemented together. However, more detailed…
Problem Most studies to date have relied on annual percent increases from baseline transit ridership in order to project the greenhouse gas emission reduction potential of transit investments. This study would…
Problem Early federal transit-related greenhouse gas (GHG) efforts such as the American Recovery and Reinvestment Act’s (ARRA) Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) grants enable transit agencies…
Problem There are several steps in the freight processing system, from warehousing, manufacture, and distribution that generate trips, usually by truck, between these stages. Often import material is in a disaggregated…
Need for the Research Stormwater runoff from transportation Rights-of-Way (ROW) may contain nutrients (particularly phosphorus and nitrogen) and may contain pathogens (though it is unclear if DOTs are a source that would…
