TRB’s Transportation Research Record : Journal of the Transportation Research Board, No. 2011 includes 22 papers that explore environmental management system development efforts, high solar reflectance concrete for pavements, silt fence tieback design methodology, integrated modeling of vehicle emissions and travel demand, hybrid diesel-electric bus emissions modeling, diesel truck idling emissions, bus idling versus urban circulator, electronic toll collection impact on air pollution levels, forecasting impact of new engine technologies on fuel consumption and emissions, and odometer reading data errors. This issue of the TRR also examines environmental impact of asphalt rubber friction course overlays, estimating environmental impact of highway incidents, environmental impact of enhanced public transport systems in South Asia, global and country inventory of highway transportation fuel consumption and air pollutant emissions, air quality benefits of freeway high-occupancy vehicle lanes in Southern California, and developing the Integrated Transportation and Ecological Enhancements for Montana process. In addition, this TRR reviews the use of highway underpasses by large mammals and other wildlife, deviation from standard state noise wall policy, metrics for communicating aircraft noise effects, geophysical remote sensing for transportation archeological investigations, recycling construction and demolition waste, and local "bring sites" to reduce householder recycling mileage.
