Vegetation Management

Common Roadside Invasives

This full-color reference guide highlights 100 invasive weeds commonly found along the Nation's roadsides. Included are common terrestrial and quickly spreading herbaceous plants, many of which are widespread and well-established problem weeds. State departments of transportation (DOTs) can use the guide as a tool to train personnel responsible for roadside management. With full-color illustrations of each weed species and lamination for protection from the elements, an accompanying field guide serves as a quick reference.

Proceedings of the 2002 Weeds Across Borders Conference

This publication features the proceedings from a conference held in May 2002 to examine the influence of surface transportation on the introduction and spread of invasive plants from a North American perspective. The recent trend to improve highway and rail traffic connections across the U.S. borders with Canada and Mexico leads to concerns that exotic plants will spread along the improved corridors as a result of increased cross-border traffic. The proceedings document the goals and results of the conference to connect across-the-border counterparts, share information, and determine possible partnerships that could help combat the further introduction and spread of invasive plants.

It All Adds Up to Cleaner Air: A Collaborative Transportation and Air Quality Public Education and Partnership Building Initiative, The First Five Years

It All Adds Up to Cleaner Air is a joint effort by FHWA and the U.S. Environmental Protection Agency (EPA) to educate the public about the connections between travel choices, congestion, and air quality. The report describes how FHWA and EPA initiated the campaign and shares the experiences of the demonstration communities that first implemented the program.

Sensitivity Analysis of MOBILE6

Motor Vehicle Emission Factor Model

FHWA recently completed a sensitivity analysis to evaluate the model behavior of MOBILE6, the current EPA model for emissions factors. The results provided an understanding of the model's behavior, especially the impacts of using localized data as compared with national default data. For copies of the report, contact Tianjia Tang at 404-562-3673.

Water Quality

The National Highway Runoff Data And Methodology Synthesis

This report provides an overview of the characteristics of highway stormwater runoff to help decisionmakers, planners, and highway engineers assess and mitigate possible adverse impacts on the Nation's receiving waters. It also provides a catalog of information, defines the necessary documentation needed to ensure the validity of data for water quality analyses, and evaluates available sources for current and foreseeable information needs. Contact Patricia Cazenas at 202-366-4085.

Management of the Discharge and Quality Of Highway Runoff in Karst Areas to Control Impacts to Ground Water

This publication presents the results of a pooled fund study to address the impacts of stormwater runoff from highways on groundwater in karst areas. The project also tested the effectiveness of a peat-filtration system in removing contaminants from highway runoff. Contact Connie Hill at 804-775-3378.

Wildlife

Wildlife Habitat Connectivity Across European Highways

This report presents the findings from an international technology scan tour sponsored by FHWA, the American Association of State Highway and Transportation Officials, and the National Cooperative Highway Research Program. The goal of the scan was to learn about European strategies to address habitat and wildlife issues associated with transportation systems. A delegation of Federal, State, and conservation group representatives visited France, Germany, the Netherlands, Slovenia, and Switzerland to observe and document efforts in Europe. The report provides conclusions and recommendations for U.S. applications in the areas of policy, communications, guidance manuals, and research on wildlife and transportation.

Wetlands

Wetlands Accounting Database

FHWA developed this interactive database as a tool to provide users with updatable information on all classes of highway projects with wetlands impacts and 404 permit requirements. The database can track and summarize the status of wetlands permits and data on impacts and mitigation for construction projects on a State, regional, or national basis. Information available in the database includes project number and type (bridge, reconstruction, etc.), location, drainage characteristics of the wetlands impacted, mitigation activities, costs per unit area, and the status of project permits. The database will help manage wetlands impacts from highway projects and compile performance data on mitigation tactics. For a copy of the database, contact Fred Bank in the FHWA Office of Natural and Human Environment at 202-366-5004 or fred.bank@fhwa.dot.gov.
