The recently completed NCHRP 08-83 study (see excerpt below) on “Analytical Travel Forecasting Approaches for Project-Level Planning and Design” addressed project-level transportation modeling in detail but only addressed air quality…
While there are a number of published studies that provide information to state and local agencies about the potential emission reduction benefits of control strategies that are designed to reduce…
There is a need for invasive species control performance standards. NCHRP Synthesis 363 identified that there are few studies that quantify benefits of invasive secies control, thus highway departments often commit…
Transportation agencies worldwide are increasingly seeking ways to cost-effectively improve the sustainability of their various activities, particularly by reducing their greenhouse gas emissions. The PVNB is one technology that highway…
When applying MOVES (MOtor Vehicle Emission Simulator) in project-level PM (particulate matter) conformity analysis, link-based traffic characteristics are required at local roadway level so as to ensure realistically representation of…
Research Idea Scope Background: Current municipal and transportation-related stormwater permits in western Washington require the use of low impact development (LID) as the preferred and commonly used approach to managing…
Background: Natural and engineered dispersion are best management practices (BMPs) designed to receive highway runoff from sheet flow for the purposes of water quality treatment and flow control. These BMPs…
Background: This research proposal seeks to study Portland Cement Pervious Concrete’s (PCPC) ability to remove pollutants, particularly heavy metals, and reduce surface volume flows from highway runoff. This study will…
Regulatory-mandated air quality analysis, such as SIP analysis, transportation conformity determinations, and project level evaluations typically require the use of multiple models (model chain) to analyze a complex chain of land use…
To identify the likelihood of suitable roost tree occupancy for both the Indiana and Northern Long-eared bat as the distance from cleared ROW increases. This would require a multi-year habitat…
